Os subprodutos da vinha são resíduos agrícolas abundantemente disponíveis em Portugal. O sector vitivinícola é um dos sectores mais representativos da economia agrícola, sendo a vinha e o olival as duas culturas permanentes dominantes em Portugal. Da atividade vitivinícola resultam várias toneladas de subprodutos entre os quais se destaca a madeira de poda de videira, o subproduto da vinha disponível em maior quantidade (massa). Os objetivos do presente trabalho consistiram na quantificação da madeira de poda de videira produzida a nível nacional (Portugal Continental) e na proposta de soluções para aproveitamento do subproduto em questão. A quantificação da madeira foi efetuada recorrendo a pesquisas realizadas junto de empresas e entidades do ramo vitivinícola. Por outro lado, a proposta de soluções de aproveitamento da madeira de poda foi feita recorrendo a exemplos estudados/implementados em Portugal e/ou noutros países, não só para este tipo de subprodutos como para outros semelhantes (como por exemplo: poda de oliveira e madeira florestal). Pelo que a presente dissertação é baseada em pesquisa e análise de dados existentes e posteriormente tratamento dos mesmos (se aplicável). Atualmente, a madeira de poda de videira representa maioritariamente uma perda de recursos e em muito dos casos acarreta para o produtor, um custo sem qualquer retorno. Para procurar soluções que permitissem conferir valor acrescentado a este subproduto da vinha, primeiramente, realizou-se um levantamento da quantidade de madeira de poda resultante das vinhas a nível nacional por NUTS II de forma a determinar a sua dispersão no território, tendo-se obtido um valor estimado de 974 mil toneladas. Seguidamente, foram estudadas três possibilidades de aproveitamento da madeira de poda: produção de Biochar, produção de biocombustíveis e produção de energia em centrais de biomassa. Para cada uma das possibilidades de aproveitamento avaliadas, foi feita uma análise da implementação de um polo industrial de conversão do subproduto num produto de valor acrescentado, tendo em conta os locais de maior produção de madeira de poda no país, as vias de transporte disponíveis e ainda o custo associado ao seu transporte. Foi ainda analisado o aproveitamento das indústrias existentes na periferia das regiões vitivinícolas de modo a avaliar a sustentabilidade do processo tanto a nível económico como ambiental. Vine by-products are agricultural residues abundantly available in Portugal. The winemaking sector is one of the most important areas of the Portuguese agriculture economy. The vineyards alongside olive groves are the two dominant permanent crops in Portugal. The winemaking activity creates several tons of by-products, among those there is the vine pruning wood, which is the biggest by-product created in this activity. The aim of the present dissertation is to quantify the available vine pruning wood at national level (Mainland Portugal) and to propose solutions for its use as a by-product. Moreover, the proposal solutions for pruning wood uses were based into studied/implemented examples in Portugal and/or in other countries, not only for this type of by-products but for similar ones (such as: olive pruning and forest wood). Therefore, the present dissertation was based on the research and analysis of existing data and the later treatment of them (if applicable). So far, vine pruning represents a great loss of resources and in most cases an unavoidable cost for the producer. In order to find solutions to add value to this by-product, surveys were carried out to determine the amount of pruning wood available at a NUTS II level. The surveys were done at the NUTS II level in order to determine their dispersal in the country. From the surveys, it was possible to estimate 974 tons of vine pruning wood available at national level. Then, three solutions for the pruning wood were studied: Biochar production, biofuel production and energy production in biomass plants. For each of the solutions, studies were carried out regarding the feasibility of the proposed processing plants to convert the by-product in an added value product. The studies analyzed the places with the greatest pruning wood production in the country, the transport routes available and the cost associated with shipping. It was also studied the use of industries near the wine regions to evaluate the sustainability of the process at both economic and environmental level.

As sociedades modernas são completamente dependentes de energia e totalmente dominadas pelos combustíveis fósseis. Contudo, questões do foro económico, geoestratégico e ambiental, das quais se destacam o elevado preço, a segurança do abastecimento, o possível esgotamento e as alterações no meio ambiente causadas pela sua exploração e utilização, evidenciam a urgência de um novo paradigma energético mundial. Com a presente dissertação pretende-se fazer uma reflexão sobre os desafios deste novo paradigma energético, o qual implica uma melhor gestão dos recursos energéticos, quer seja pela poupança quer seja pelo uso mais eficiente dos mesmos. É também muito importante neste âmbito travar a dependência dos combustíveis fósseis, substituindo-os por energias limpas. Assim sendo, este estudo foca de que forma e com que intensidade a descarbonização das economias modernas se está a realizar, privilegiando o uso de fontes de energia renovável em detrimento dos combustíveis fósseis, cuja combustão é considerada a mais importante causa antropogénica do aquecimento global. É dado particular ênfase à economia europeia e a Portugal, em especial, caracterizado por uma forte dependência de combustíveis fósseis. O incremento de energias renováveis na produção energética, o aumento da eficiência energética e a exploração dos depósitos de petróleo e gás natural, que são hoje conhecidos em solo luso, podem permitir aliviar a pesada fatura energética nacional. É feita ainda uma breve apresentação da política energética comunitária e nacional e respetivo enquadramento legal. Modern societies are completely dependent on energy and totally dominated by fossil fuels. However, economic, geostrategic and environmental issues, such as the high price level, supply security reasons, the possible exhaustion and environment damages caused by the exploitation and use of fossil fuels, stand out the urgent need for a new world energy paradigm. This dissertation reflects on the challenges of this new energy paradigm. It inevitably implies a far better management of energy resources, whether by saving or using them more efficiently. Clean energy is also very important and it plays a crucial role if the world wants to stop the huge dependence on fossil fuels. Therefore, this study focuses on how and with what intensity the decarbonization of modern economies is happening, favouring renewable energy sources instead of fossil fuels whose combustion is leading to global warming. This study gives particular emphasis to the European economy and, specially, to Portugal. Our country is strongly dependent on fossil fuels. The increase of renewable energy sources in energy production, the increase in energy efficiency and the exploitation of oil and natural gas deposits, which are currently known in Portuguese soil, can help relieving our heavy national energy bill. Finally, there is a brief presentation of European and national energy policy and its legal framework.

A presente dissertação aborda a Bioeconomia enquanto estratégia económica que tem como plano de ação a utilização sustentável dos recursos renováveis para fins industriais e alimentares, garantindo simultaneamente a proteção do meio ambiente. Dado o caráter transversal da Bioeconomia esta constitui uma oportunidade única para enfrentar desafios atuais da sociedade interligados, tais como: a segurança alimentar, a escassez de recursos naturais, a dependência de recursos fósseis e as alterações climáticas, a par com um crescimento económico sustentável. Com este trabalho pretende-se compreender a Bioeconomia enquanto novo paradigma económico. É analisada a Bioeconomia na produção de recursos biológicos renováveis e na conversão dos mesmos recursos e fluxos de resíduos em produtos de valor acrescentado, tais como alimentos para consumo humano e animal, produtos de base biológica e bioenergia. Neste contexto, a investigação e a inovação são determinantes, assim como a interação entre as atuais políticas de promoção da Bioeconomia a nível da União Europeia e do mundo, de modo a fomentar as melhores práticas em questões globais em domínios como os da saúde, alterações demográficas e bem-estar da população mundial e com vista à implementação de uma política bioeconómica global. Com o trabalho, pretende-se ainda obter uma visão de como a Bioeconomia vem sendo implementada no mundo, verificando-se que vem avançando a um ritmo acelerado em muitos países europeus, bem como em alguns países americanos e asiáticos. This dissertation is about Bioeconomy as an economic strategy that aims the sustainable use of renewable resources for industrial and food purposes, while ensuring the protection of the environment. Given the cross-cutting nature of Bioeconomy, it is a unique opportunity to address today's interlinked societal challenges such as: food security, natural resources scarcity, dependence on fossil fuels and climate change, together with sustainable economic growth. The dissertation aims a better understanding of Bioeconomy as a new economic paradigm. It focuses the production of renewable biological resources and the conversion of the same resources and waste streams into value added products such as food and feed, biobased products and bioenergy. In this context, research and innovation are crucial, as well as the interaction between the current promotion policies of Bioeconomy in the European Union and in the world, in order to promote best practices in global issues such as health, demographic change and well-being of the world's population and also aiming the implementation of a global Bioeconomy strategy. The dissertation also aims to get a global picture about how Bioeconomy is being implemented worldwide. It has gained special emphasis in many European countries, as well as in some American and Asian countries.

A indústria da moda é a segunda maior poluidora industrial depois da aviação, respondendo por até 10 % da poluição global. No entanto, apesar desse impacto ambiental amplamente divulgado, a indústria continua a crescer, em parte devido ao surgimento da fast fashion, que depende da mão de obra de baixo custo, do consumo excessivo e de vestuário de curta duração. Posto isto, é essencial que haja uma desaceleração da produção, de volta para a slow fashion, a introdução de práticas sustentáveis por toda a cadeia de abastecimento e uma mudança no comportamento do consumidor. A presente dissertação contribuiu para a melhoria da sustentabilidade da Sonae Fashion, onde o principal objetivo foi o apoio na definição da estratégia de melhoria e no desenvolvimento de modelo negócio para o plástico e denim responsável. Em relação ao denim da marca Salsa, foi necessário analisar a sua rastreabilidade (pegada ambiental, logística, geografia), estudar benchmarks de denim sustentável e responsável, e desenvolver um plano de alternativas mais sustentável. Relativamente aos plásticos das marcas MO, Zippy e Salsa, foi necessário analisar todo o plástico das lojas, desde a sua chegada à loja até à sua saída, quantificar, tipificar e cadastrar os tipos de plásticos, estudar alternativas para reduzir o seu consumo e apoiar a definição de estratégia e modelo de negócio para a sustentabilidade, circularidade e reciclagem do plástico. Concluiu-se, em relação ao denim, que 1 par de calças de ganga 100 % algodão consome 2 096 L de água, 760 g de algodão, 3,31 g de soluções químicas, 3,36 g de hipoclorito de sódio e 0,4 kg de pedra-pomes, necessita de uma área de 4,81 m2 , e tem uma pegada de carbono de, 6,01 kg. Através destes resultados foi possível desenvolver um modelo de negócio para tornar o denim ambientalmente mais responsável optando, por exemplo, pelo uso de cânhamo como matéria-prima, pela implementação de tecnologias de acabamento com menor consumo de água e químicos e pela conscientização dos consumidores em relação aos seus impactos. Nos plásticos, após a quantificação e tipificação do plástico que chega ao consumidor final nas lojas MO e Zippy, foi possível concluir que no ano de 2019 o mais consumido foi o PEBD, cerca de 74 toneladas, e o segundo mais consumido foi o PVC, cerca de 39 toneladas. Para além disso, confirmou-se que o plástico gerado nas lojas MO, Zippy e Salsa, é corretamente tratado, sendo recolhido e encaminhado para a reciclagem. Com estes resultados, foi possível desenvolver um modelo de negócio para o plástico através da eliminação, substituição e reutilização das embalagens. The fashion industry is the second largest industrial polluter after aviation, accounting for up to 10 % of global pollution. Yet, despite this widely publicized environmental impact, the industry continues to grow, in part due to the rise of fast fashion, which relies on cheap labor, overconsumption and short lived clothing. That being said, it is essential that there is a slowdown in production, back to slow fashion, the introduction of sustainable practices throughout the supply chain and a change in consumer behavior. This dissertation contributed to improving Sonae Fashion's sustainability, where the main objective was to support the definition of the improvement strategy and the development of a business model for responsible plastic and denim. In relation to denim from the Salsa brand, it was necessary to analyze the traceability of denim (environmental footprint, logistics, geography), study sustainable and responsible denim benchmarks, and develop a plan of more sustainable alternatives. Regarding plastics of the MO, Zippy and Salsa brands, it was necessary to analyze all the plastic from the MO, Zippy and Salsa stores from its arrival at the store to its departure, quantify, typify and register the types of plastics, study alternatives to reduce the consumption and support the definition of a strategy and business model for the sustainability, circularity and recycling of plastic. It was concluded, in relation to denim, that 1 pair of 100 % cotton jeans consumes 2 096 L of water, 760 g of cotton, 3,31 g of chemical solutions, 3,36 g of sodium hypochlorite and 0,4 kg of pumice stone, needs an area of 4,81 m2 , and has a carbon footprint of about 6,01 kg. Through these results, it was possible to develop a business model to make denim more environmentally responsible, opting, for example, for the use of hemp as a raw material, for the implementation of finishing technologies with less consumption of water and chemicals and for the awareness of the consumers regardind their impacts. In plastics, after quantifying and typifying the plastic that reaches the final consumer at MO and Zippy stores, it was possible to conclude that in 2019 the most consumed was LDPE, around 74 tons, and the second most consumed was PVC, about 39 tons. Furthermore, it was confirmed that the plastic generated in the MO, Zippy and Salsa stores is correctly treated, being collected and sent for recycling. With these results, it was possible to develop a business model for plastic through the elimination, replacement and reuse of packaging. Dissertação de mestrado integrado em Engenharia Biológica

Currently there is a growing concern about climate change resulting from increased CO2 emissions, leading to an increasing demand of buildings that are more sustainable and energy efficient. The AEC industry have been acquiring more demanding standards of sustainability and energy efficiency, requiring analysis processes to be more complex and integrated with each other. Therefore, it has become vital to implement BIM, enabling greater efficiency in the collaborative process between actors. Thus, the use of BIM can contribute to sustainability through forecasting energy consumption and their usage costs with credibility, reliability and consistency of results. The study of the benefits and barriers to the introduction of BIM in energy analysis of buildings and the analysis of the interoperability between BIM tools and specialized software for energy analysis becomes relevant, as well as the study of workflows that provide good efficiency, which will boost its correct implementation in the AEC industry Currently there is a growing concern about climate change resulting from increased CO2 emissions, leading to an increasing demand of buildings that are more sustainable and energy efficient.

A generalidade dos hotéis apresenta um serviço que nem sempre deixa o cliente satisfeito, coexistindo diferentes perspetivas no que concerne o valor acrescentado dos produtos, do ponto de vista do gestor, e aquilo que se poderá designar pela experiência do turista e a forma como este perceciona o serviço. No sentido de mudar esse paradigma e responder a tendências atuais, as unidades hoteleiras começam a demonstrar uma maior preocupação com a sustentabilidade e a personalização do serviço, muito embora ainda estejam muito longe de alcançar um patamar de sustentabilidade percebido pelo cliente. Este projeto visa desenvolver um projeto para a criação de um hotel com infraestruturas adequadas a clientes com dificuldades de mobilidade, física, visual ou auditiva, criando acessos em todas as áreas comuns para que os mesmos se sintam integrados. Para além dessa vertente, o hotel primará pela sustentabilidade, desde as fontes de energia utilizadas, passando pela economia circular, no sentido de abranger todos os critérios de sustentabilidade e políticas de desenvolvimento sustentável. Para além das infraestruturas, o principal elemento diferenciador deste hotel será o tipo de serviço oferecido aos clientes, que será personalizado, permitindo aos mesmos visitar sem preocupações vários destinos e até experienciar atividades completamente inovadoras. Tendo por base este pressupostos, definiram-se objetivos específicos que se encontram orientados para a sustentabilidade e adaptabilidade, sendo eles os seguintes: a definição de estratégias de economia circular na infraestrutura paisagística do hotel; o desenvolvimento da procura pelo serviço diferenciador na área da hotelaria e turismo; o desenvolvimento de solução para mobilidade reduzida; o aumento da utilização de energias renováveis; a definição de novas estratégias de sustentabilidade na hotelaria; Recorrendo à elaboração de um plano de negócios, no âmbito do desenvolvimento deste projeto, realizou-se uma a análise de mercado, tendo por base um inquérito por questionário aplicado a profissionais de hotelaria e turismo e a viajantes e turistas, no sentido de permitir recolher e confrontar diferentes perspetivas relativas à temática da inclusão e da sustentabilidade. Procedeu-se ainda à análise económica e financeira através do modelo FINICIA desenvolvido por IAPMEI – Agência para a Competitividade e Inovação que permitiu analisar a rendibilidade e viabilidade da empresa. Como principais resultados encontramos um VAL positivo nos três métodos utilizados. Sendo estes métodos o pós financiamento, com um VAL positivo de 2 632 489€, o pré-financiamento, com um VAL positivo de 1 466 645€ e o investidor, com um VAL positivo de 1 883 207€. Concluímos que o projeto é viável uma vez que o VAL é positivo nos três métodos referidos. Este plano de negócios demonstra que o projeto pode avançar para a concretização efetiva.

São as empresas e as organizações em geral, os motores fundamentais da economia e da geração de riqueza e de valor, estando este valor não só associado aos seus produtos e serviços, mas também à forma como os desenvolvem e ao impacto que a sua atividade pode provocar. Numa adaptação aos novos tempos e às necessidades do mercado, as empresas estão cada vez mais conscientes do impacto que podem ter a nível económico, social e ambiental. A sustentabilidade pode ser vista como uma vertente estratégica, que permite às organizações otimizar as suas atividades e adotar uma postura de proatividade e de desenvolvimento sustentável. Contudo, para obter real sustentabilidade, não basta otimizar e reduzir, é também necessário aplicar estratégias e colocar em prática medidas de forma a garantir os níveis mínimos dos ativos ambientais, protegendo assim gerações futuras. Este estudo pretende responder à questão de investigação: “Como é que o relatório de sustentabilidade pode ser uma mais-valia para a indústria automóvel?", através de um caso de estudo na empresa Mário da Costa Martins. Pretende-se então compreender quais as práticas sustentáveis usadas na indústria automóvel, o que é possível melhorar e de que forma. No relatório de sustentabilidade, que esta dissertação pretende desenvolver, será aplicada a metodologia sugerida pela Global Reporting Initiative (GRI). Foi ainda proposta uma metodologia de análise inovadora que permite avaliar o desempenho de sustentabilidade da empresa através do relatório de sustentabilidade elaborado. Companies and organizations in general are the fundamental movers and shakers of the economy and responsible for much of the wealth, with this value not only associated with products and services that they provide, but also with the way they develop them and the impact that their activity can have on society. In order to adapt to new times and market needs, companies are increasingly aware of the impact they can have on an economic, social and environmental level. Sustainability can be seen as a strategic aspect, which allows organizations to optimize activities and adopt a proactive and sustainable stance towards development. However, to achieve real sustainability, it is not enough to optimize and cut costs, it is also necessary to apply strategies and put measures into practice in order to guarantee the minimum levels of environmental assets, thus protecting future generations. This study aims to answer the research question: "How can the sustainability report add value to the automotive industry?", through a case study at the company Mário da Costa Martins. This study focuses on sustainable practices already in practice in the automotive industry, what and how can things in MCM be improved. The methodology suggested by the Global Reporting Initiative (GRI) will be applied on the sustainability report, which this dissertation intends to develop. A new method to evaluate firms’ sustainability performance through sustainability report was developed and presented. Dissertação de mestrado em Economia Monetária Bancária e Financeira

A sustentabilidade é um fenómeno que cada vez tem mais importância nos dias de hoje. Os consumidores estão mais informados e conscientes do impacto que as suas escolhas de consumo podem ter no ambiente e na sociedade. Em simultâneo, como resposta a estas preocupações e com o intuito de tornar o mundo num lugar melhor, as empresas sentem a necessidade de criar novas estratégias. A responsabilidade social corporativa e o “green marketing” são algumas das tendências e práticas. Estas têm, por um lado, o objetivo de minimizar o seu impacto e, por outro, o de promover um mundo mais equilibrado a nível económico, social e ambiental. Esta temática tem vindo a crescer e a apresentar novas oportunidades para as marcas. Este relatório resulta de um trabalho de pesquisa e análise desenvolvido no estágio curricular realizado entre Fevereiro de 2019 e Fevereiro de 2020 na marca Lipton, integrante da multinacional Unilever. O principal objetivo é perceber quais as estratégias da marca para promover um consumo mais responsável e sustentável. Sustainability is a phenomenon that has been becoming a very important matter nowadays. Customers are becoming highly informed and conscious about the impact that their consuming choices have on the environment and the society. Simultaneously, as an answer to these matters and to turn the world into a better place, companies are being forced to take action in order to minimize their negative impact, developing new sustainable measures. Corporate social responsibility and green marketing are some of the strategies adopted. Furthermore, companies have the goal to make this world a more economic, social and environmentally balanced one. In fact, this reality has brought an opportunity for brands to reinvent themselves. This report was emerged by an internship held for Lipton from February 2019 to February 2020, integrant brand of Unilever. The main goal is to understand which strategies were chosen to promote a responsible and sustainable consumption.

As alterações climáticas são um tema de extrema importância nos dias de hoje sendo um tópico que preocupa a população mundial. Alguns fatores humanos são responsáveis por este fenómeno, tais como a queima de combustíveis fósseis, nomeadamente a queima de petróleo, carvão ou gás que liberta CO2 e N2O para a atmosfera, o uso de fertilizantes, aumento da atividade pecuária e causas associadas à desflorestação. O impacto cada vez mais acentuado do CO2 atmosférico, assim como da temperatura, tem desencadeado um avanço de fenómenos naturais desde secas e precipitação intensa, até à evidência de perda nutricional de proteína, ferro (Fe) e zinco (Zn) em diversos vegetais, incluindo as leguminosas como soja (Glycine max. L.) e feijão (Phaseolus vulgaris L.). Em particular, as populações de países em desenvolvimento, que tenham grande dependência nas leguminosas como fontes de nutrientes, poderão vir a ser especialmente impactadas devido ao CO2 elevado. Neste projeto estudaram-se duas leguminosas, a soja cv. Thorne e o cv. Papo de rola. Realizaram-se dois ensaios: o primeiro a 400 ppm (CO2 ambiental), e o segundo a 800 ppm (valores previstos para 2050) e, em cada um destes, as plantas foram crescidas na presença e na ausência de Fe. As plantas foram mantidas em câmaras de fitoclima com temperatura, humidade e CO2 controlado. Após a recolha de dados e análise estatística percebeu-se que na soja existe um aumento do peso seco a alto CO2 (+ 52,09 % em folhas e + 60,47 % em raízes). Também se verifica que as amostras de soja e feijão que que cresceram com Fe desenvolvem-se mais (+ 67,49 % em peso seco das folhas e + 60,70 % em raízes de soja; + 91,11 % em folhas e + 77,95 % em raízes de feijão). No entanto, houve reduções na atividade da redutase férrica radicular (94,79 % em soja e 72,19 % para feijão), no teor de clorofila foliar (75,42 % em soja e 73,39 % em feijão) e na taxa fotossintética (90,46 % em soja e 58,13 % em feijão) quando comparadas com as plantas crescidas a CO2 ambiental e na ausência de Fe. Nas análises nutricionais, verifica-se maior teor proteico (55,32 %), retenção mineral (especialmente Fe e Zn), assim como, maior teor de ácidos e açúcares a CO2 ambiental com Fe. Em síntese, a soja e o feijão crescidos com Fe indicam melhores condições de sobrevivência para a planta, sendo que o maior crescimento a alto CO2 não determina necessariamente maior teor nutricional. Climate change is a topic of great importance these days being a subject of concern to the world´s population. Several human factors are responsible for this event, such as the burning of fossil fuels, namely of oil, coal or gas -that release CO2 and N2O to the atmosphere, the use of fertilizers, increased livestock production and deforestation. The increasing impact of atmospheric CO2, as well as temperature has triggered an advance of natural phenomena from droughts and intense precipitation to the evidence of nutritional loss of protein, iron (Fe) and zinc (Zn) in several plants, including legumes such as soybean (Glycine max. L.) and common bean (Phaseolus vulgaris L.). Populations in developing countries which are highly reliant on legumes as main sources of nutrients may be especially vulnerble in the future due to elevated CO2. Here, two legume grains, soybean cv. Thorne and common bean cv. Papo de rola were analyzed. Plants were grown in growth chambers, with controlled temperature, humidity and CO2. Two experiments were carried out, the first one at 400 ppm (environmental CO2) and the second at 800 ppm (values predicted for 2050). In each experiment, a set of plants grew with Fe and another set without this mineral. After data collection and statistical analysis it was observed that in soybean there is an increased dry weight at high CO2 (52.09 % in leaves and 60.47 % in roots). It is also verified that the samples of soybean and beans that grew with Fe had higher biomass (67.49 % in leaves and 60.70 % in roots of soybean; 91.11 % in leaves and 77.95 % in roots of common beans). However, there was a reduction in the activity of the root iron reductase (94.79 % in soybeans and 72.19 % in beans), in leaf chlorophyll content (75.42 % in soybean and 73.39 % in bean) and photosynthetic rate (90.46 % in soybean and 58.13 % in beans) when compared to plants that grew at ambient CO2 and in the absence of Fe. With regards to the nutritional analysis, a higher protein concentration (55.32 %), mineral retention, especially Fe and Zn, was verified, as well as a higher content of organic acids and sugars at ambient CO2 with Fe. In summary, Fe promotes better survival conditions for soybean and bean, and the higher growth at high CO2 does not reflect in higher nutritional content.

Os subprodutos da vinha são resíduos agrícolas abundantemente disponíveis em Portugal. O sector vitivinícola é um dos sectores mais representativos da economia agrícola, sendo a vinha e o olival as duas culturas permanentes dominantes em Portugal. Da atividade vitivinícola resultam várias toneladas de subprodutos entre os quais se destaca a madeira de poda de videira, o subproduto da vinha disponível em maior quantidade (massa). Os objetivos do presente trabalho consistiram na quantificação da madeira de poda de videira produzida a nível nacional (Portugal Continental) e na proposta de soluções para aproveitamento do subproduto em questão. A quantificação da madeira foi efetuada recorrendo a pesquisas realizadas junto de empresas e entidades do ramo vitivinícola. Por outro lado, a proposta de soluções de aproveitamento da madeira de poda foi feita recorrendo a exemplos estudados/implementados em Portugal e/ou noutros países, não só para este tipo de subprodutos como para outros semelhantes (como por exemplo: poda de oliveira e madeira florestal). Pelo que a presente dissertação é baseada em pesquisa e análise de dados existentes e posteriormente tratamento dos mesmos (se aplicável). Atualmente, a madeira de poda de videira representa maioritariamente uma perda de recursos e em muito dos casos acarreta para o produtor, um custo sem qualquer retorno. Para procurar soluções que permitissem conferir valor acrescentado a este subproduto da vinha, primeiramente, realizou-se um levantamento da quantidade de madeira de poda resultante das vinhas a nível nacional por NUTS II de forma a determinar a sua dispersão no território, tendo-se obtido um valor estimado de 974 mil toneladas. Seguidamente, foram estudadas três possibilidades de aproveitamento da madeira de poda: produção de Biochar, produção de biocombustíveis e produção de energia em centrais de biomassa. Para cada uma das possibilidades de aproveitamento avaliadas, foi feita uma análise da implementação de um polo industrial de conversão do subproduto num produto de valor acrescentado, tendo em conta os locais de maior produção de madeira de poda no país, as vias de transporte disponíveis e ainda o custo associado ao seu transporte. Foi ainda analisado o aproveitamento das indústrias existentes na periferia das regiões vitivinícolas de modo a avaliar a sustentabilidade do processo tanto a nível económico como ambiental. Vine by-products are agricultural residues abundantly available in Portugal. The winemaking sector is one of the most important areas of the Portuguese agriculture economy. The vineyards alongside olive groves are the two dominant permanent crops in Portugal. The winemaking activity creates several tons of by-products, among those there is the vine pruning wood, which is the biggest by-product created in this activity. The aim of the present dissertation is to quantify the available vine pruning wood at national level (Mainland Portugal) and to propose solutions for its use as a by-product. Moreover, the proposal solutions for pruning wood uses were based into studied/implemented examples in Portugal and/or in other countries, not only for this type of by-products but for similar ones (such as: olive pruning and forest wood). Therefore, the present dissertation was based on the research and analysis of existing data and the later treatment of them (if applicable). So far, vine pruning represents a great loss of resources and in most cases an unavoidable cost for the producer. In order to find solutions to add value to this by-product, surveys were carried out to determine the amount of pruning wood available at a NUTS II level. The surveys were done at the NUTS II level in order to determine their dispersal in the country. From the surveys, it was possible to estimate 974 tons of vine pruning wood available at national level. Then, three solutions for the pruning wood were studied: Biochar production, biofuel production and energy production in biomass plants. For each of the solutions, studies were carried out regarding the feasibility of the proposed processing plants to convert the by-product in an added value product. The studies analyzed the places with the greatest pruning wood production in the country, the transport routes available and the cost associated with shipping. It was also studied the use of industries near the wine regions to evaluate the sustainability of the process at both economic and environmental level.

As sociedades modernas são completamente dependentes de energia e totalmente dominadas pelos combustíveis fósseis. Contudo, questões do foro económico, geoestratégico e ambiental, das quais se destacam o elevado preço, a segurança do abastecimento, o possível esgotamento e as alterações no meio ambiente causadas pela sua exploração e utilização, evidenciam a urgência de um novo paradigma energético mundial. Com a presente dissertação pretende-se fazer uma reflexão sobre os desafios deste novo paradigma energético, o qual implica uma melhor gestão dos recursos energéticos, quer seja pela poupança quer seja pelo uso mais eficiente dos mesmos. É também muito importante neste âmbito travar a dependência dos combustíveis fósseis, substituindo-os por energias limpas. Assim sendo, este estudo foca de que forma e com que intensidade a descarbonização das economias modernas se está a realizar, privilegiando o uso de fontes de energia renovável em detrimento dos combustíveis fósseis, cuja combustão é considerada a mais importante causa antropogénica do aquecimento global. É dado particular ênfase à economia europeia e a Portugal, em especial, caracterizado por uma forte dependência de combustíveis fósseis. O incremento de energias renováveis na produção energética, o aumento da eficiência energética e a exploração dos depósitos de petróleo e gás natural, que são hoje conhecidos em solo luso, podem permitir aliviar a pesada fatura energética nacional. É feita ainda uma breve apresentação da política energética comunitária e nacional e respetivo enquadramento legal. Modern societies are completely dependent on energy and totally dominated by fossil fuels. However, economic, geostrategic and environmental issues, such as the high price level, supply security reasons, the possible exhaustion and environment damages caused by the exploitation and use of fossil fuels, stand out the urgent need for a new world energy paradigm. This dissertation reflects on the challenges of this new energy paradigm. It inevitably implies a far better management of energy resources, whether by saving or using them more efficiently. Clean energy is also very important and it plays a crucial role if the world wants to stop the huge dependence on fossil fuels. Therefore, this study focuses on how and with what intensity the decarbonization of modern economies is happening, favouring renewable energy sources instead of fossil fuels whose combustion is leading to global warming. This study gives particular emphasis to the European economy and, specially, to Portugal. Our country is strongly dependent on fossil fuels. The increase of renewable energy sources in energy production, the increase in energy efficiency and the exploitation of oil and natural gas deposits, which are currently known in Portuguese soil, can help relieving our heavy national energy bill. Finally, there is a brief presentation of European and national energy policy and its legal framework.

A presente dissertação aborda a Bioeconomia enquanto estratégia económica que tem como plano de ação a utilização sustentável dos recursos renováveis para fins industriais e alimentares, garantindo simultaneamente a proteção do meio ambiente. Dado o caráter transversal da Bioeconomia esta constitui uma oportunidade única para enfrentar desafios atuais da sociedade interligados, tais como: a segurança alimentar, a escassez de recursos naturais, a dependência de recursos fósseis e as alterações climáticas, a par com um crescimento económico sustentável. Com este trabalho pretende-se compreender a Bioeconomia enquanto novo paradigma económico. É analisada a Bioeconomia na produção de recursos biológicos renováveis e na conversão dos mesmos recursos e fluxos de resíduos em produtos de valor acrescentado, tais como alimentos para consumo humano e animal, produtos de base biológica e bioenergia. Neste contexto, a investigação e a inovação são determinantes, assim como a interação entre as atuais políticas de promoção da Bioeconomia a nível da União Europeia e do mundo, de modo a fomentar as melhores práticas em questões globais em domínios como os da saúde, alterações demográficas e bem-estar da população mundial e com vista à implementação de uma política bioeconómica global. Com o trabalho, pretende-se ainda obter uma visão de como a Bioeconomia vem sendo implementada no mundo, verificando-se que vem avançando a um ritmo acelerado em muitos países europeus, bem como em alguns países americanos e asiáticos. This dissertation is about Bioeconomy as an economic strategy that aims the sustainable use of renewable resources for industrial and food purposes, while ensuring the protection of the environment. Given the cross-cutting nature of Bioeconomy, it is a unique opportunity to address today's interlinked societal challenges such as: food security, natural resources scarcity, dependence on fossil fuels and climate change, together with sustainable economic growth. The dissertation aims a better understanding of Bioeconomy as a new economic paradigm. It focuses the production of renewable biological resources and the conversion of the same resources and waste streams into value added products such as food and feed, biobased products and bioenergy. In this context, research and innovation are crucial, as well as the interaction between the current promotion policies of Bioeconomy in the European Union and in the world, in order to promote best practices in global issues such as health, demographic change and well-being of the world's population and also aiming the implementation of a global Bioeconomy strategy. The dissertation also aims to get a global picture about how Bioeconomy is being implemented worldwide. It has gained special emphasis in many European countries, as well as in some American and Asian countries.

A indústria da moda é a segunda maior poluidora industrial depois da aviação, respondendo por até 10 % da poluição global. No entanto, apesar desse impacto ambiental amplamente divulgado, a indústria continua a crescer, em parte devido ao surgimento da fast fashion, que depende da mão de obra de baixo custo, do consumo excessivo e de vestuário de curta duração. Posto isto, é essencial que haja uma desaceleração da produção, de volta para a slow fashion, a introdução de práticas sustentáveis por toda a cadeia de abastecimento e uma mudança no comportamento do consumidor. A presente dissertação contribuiu para a melhoria da sustentabilidade da Sonae Fashion, onde o principal objetivo foi o apoio na definição da estratégia de melhoria e no desenvolvimento de modelo negócio para o plástico e denim responsável. Em relação ao denim da marca Salsa, foi necessário analisar a sua rastreabilidade (pegada ambiental, logística, geografia), estudar benchmarks de denim sustentável e responsável, e desenvolver um plano de alternativas mais sustentável. Relativamente aos plásticos das marcas MO, Zippy e Salsa, foi necessário analisar todo o plástico das lojas, desde a sua chegada à loja até à sua saída, quantificar, tipificar e cadastrar os tipos de plásticos, estudar alternativas para reduzir o seu consumo e apoiar a definição de estratégia e modelo de negócio para a sustentabilidade, circularidade e reciclagem do plástico. Concluiu-se, em relação ao denim, que 1 par de calças de ganga 100 % algodão consome 2 096 L de água, 760 g de algodão, 3,31 g de soluções químicas, 3,36 g de hipoclorito de sódio e 0,4 kg de pedra-pomes, necessita de uma área de 4,81 m2 , e tem uma pegada de carbono de, 6,01 kg. Através destes resultados foi possível desenvolver um modelo de negócio para tornar o denim ambientalmente mais responsável optando, por exemplo, pelo uso de cânhamo como matéria-prima, pela implementação de tecnologias de acabamento com menor consumo de água e químicos e pela conscientização dos consumidores em relação aos seus impactos. Nos plásticos, após a quantificação e tipificação do plástico que chega ao consumidor final nas lojas MO e Zippy, foi possível concluir que no ano de 2019 o mais consumido foi o PEBD, cerca de 74 toneladas, e o segundo mais consumido foi o PVC, cerca de 39 toneladas. Para além disso, confirmou-se que o plástico gerado nas lojas MO, Zippy e Salsa, é corretamente tratado, sendo recolhido e encaminhado para a reciclagem. Com estes resultados, foi possível desenvolver um modelo de negócio para o plástico através da eliminação, substituição e reutilização das embalagens. The fashion industry is the second largest industrial polluter after aviation, accounting for up to 10 % of global pollution. Yet, despite this widely publicized environmental impact, the industry continues to grow, in part due to the rise of fast fashion, which relies on cheap labor, overconsumption and short lived clothing. That being said, it is essential that there is a slowdown in production, back to slow fashion, the introduction of sustainable practices throughout the supply chain and a change in consumer behavior. This dissertation contributed to improving Sonae Fashion's sustainability, where the main objective was to support the definition of the improvement strategy and the development of a business model for responsible plastic and denim. In relation to denim from the Salsa brand, it was necessary to analyze the traceability of denim (environmental footprint, logistics, geography), study sustainable and responsible denim benchmarks, and develop a plan of more sustainable alternatives. Regarding plastics of the MO, Zippy and Salsa brands, it was necessary to analyze all the plastic from the MO, Zippy and Salsa stores from its arrival at the store to its departure, quantify, typify and register the types of plastics, study alternatives to reduce the consumption and support the definition of a strategy and business model for the sustainability, circularity and recycling of plastic. It was concluded, in relation to denim, that 1 pair of 100 % cotton jeans consumes 2 096 L of water, 760 g of cotton, 3,31 g of chemical solutions, 3,36 g of sodium hypochlorite and 0,4 kg of pumice stone, needs an area of 4,81 m2 , and has a carbon footprint of about 6,01 kg. Through these results, it was possible to develop a business model to make denim more environmentally responsible, opting, for example, for the use of hemp as a raw material, for the implementation of finishing technologies with less consumption of water and chemicals and for the awareness of the consumers regardind their impacts. In plastics, after quantifying and typifying the plastic that reaches the final consumer at MO and Zippy stores, it was possible to conclude that in 2019 the most consumed was LDPE, around 74 tons, and the second most consumed was PVC, about 39 tons. Furthermore, it was confirmed that the plastic generated in the MO, Zippy and Salsa stores is correctly treated, being collected and sent for recycling. With these results, it was possible to develop a business model for plastic through the elimination, replacement and reuse of packaging. Dissertação de mestrado integrado em Engenharia Biológica

Currently there is a growing concern about climate change resulting from increased CO2 emissions, leading to an increasing demand of buildings that are more sustainable and energy efficient. The AEC industry have been acquiring more demanding standards of sustainability and energy efficiency, requiring analysis processes to be more complex and integrated with each other. Therefore, it has become vital to implement BIM, enabling greater efficiency in the collaborative process between actors. Thus, the use of BIM can contribute to sustainability through forecasting energy consumption and their usage costs with credibility, reliability and consistency of results. The study of the benefits and barriers to the introduction of BIM in energy analysis of buildings and the analysis of the interoperability between BIM tools and specialized software for energy analysis becomes relevant, as well as the study of workflows that provide good efficiency, which will boost its correct implementation in the AEC industry Currently there is a growing concern about climate change resulting from increased CO2 emissions, leading to an increasing demand of buildings that are more sustainable and energy efficient.

A generalidade dos hotéis apresenta um serviço que nem sempre deixa o cliente satisfeito, coexistindo diferentes perspetivas no que concerne o valor acrescentado dos produtos, do ponto de vista do gestor, e aquilo que se poderá designar pela experiência do turista e a forma como este perceciona o serviço. No sentido de mudar esse paradigma e responder a tendências atuais, as unidades hoteleiras começam a demonstrar uma maior preocupação com a sustentabilidade e a personalização do serviço, muito embora ainda estejam muito longe de alcançar um patamar de sustentabilidade percebido pelo cliente. Este projeto visa desenvolver um projeto para a criação de um hotel com infraestruturas adequadas a clientes com dificuldades de mobilidade, física, visual ou auditiva, criando acessos em todas as áreas comuns para que os mesmos se sintam integrados. Para além dessa vertente, o hotel primará pela sustentabilidade, desde as fontes de energia utilizadas, passando pela economia circular, no sentido de abranger todos os critérios de sustentabilidade e políticas de desenvolvimento sustentável. Para além das infraestruturas, o principal elemento diferenciador deste hotel será o tipo de serviço oferecido aos clientes, que será personalizado, permitindo aos mesmos visitar sem preocupações vários destinos e até experienciar atividades completamente inovadoras. Tendo por base este pressupostos, definiram-se objetivos específicos que se encontram orientados para a sustentabilidade e adaptabilidade, sendo eles os seguintes: a definição de estratégias de economia circular na infraestrutura paisagística do hotel; o desenvolvimento da procura pelo serviço diferenciador na área da hotelaria e turismo; o desenvolvimento de solução para mobilidade reduzida; o aumento da utilização de energias renováveis; a definição de novas estratégias de sustentabilidade na hotelaria; Recorrendo à elaboração de um plano de negócios, no âmbito do desenvolvimento deste projeto, realizou-se uma a análise de mercado, tendo por base um inquérito por questionário aplicado a profissionais de hotelaria e turismo e a viajantes e turistas, no sentido de permitir recolher e confrontar diferentes perspetivas relativas à temática da inclusão e da sustentabilidade. Procedeu-se ainda à análise económica e financeira através do modelo FINICIA desenvolvido por IAPMEI – Agência para a Competitividade e Inovação que permitiu analisar a rendibilidade e viabilidade da empresa. Como principais resultados encontramos um VAL positivo nos três métodos utilizados. Sendo estes métodos o pós financiamento, com um VAL positivo de 2 632 489€, o pré-financiamento, com um VAL positivo de 1 466 645€ e o investidor, com um VAL positivo de 1 883 207€. Concluímos que o projeto é viável uma vez que o VAL é positivo nos três métodos referidos. Este plano de negócios demonstra que o projeto pode avançar para a concretização efetiva.

São as empresas e as organizações em geral, os motores fundamentais da economia e da geração de riqueza e de valor, estando este valor não só associado aos seus produtos e serviços, mas também à forma como os desenvolvem e ao impacto que a sua atividade pode provocar. Numa adaptação aos novos tempos e às necessidades do mercado, as empresas estão cada vez mais conscientes do impacto que podem ter a nível económico, social e ambiental. A sustentabilidade pode ser vista como uma vertente estratégica, que permite às organizações otimizar as suas atividades e adotar uma postura de proatividade e de desenvolvimento sustentável. Contudo, para obter real sustentabilidade, não basta otimizar e reduzir, é também necessário aplicar estratégias e colocar em prática medidas de forma a garantir os níveis mínimos dos ativos ambientais, protegendo assim gerações futuras. Este estudo pretende responder à questão de investigação: “Como é que o relatório de sustentabilidade pode ser uma mais-valia para a indústria automóvel?", através de um caso de estudo na empresa Mário da Costa Martins. Pretende-se então compreender quais as práticas sustentáveis usadas na indústria automóvel, o que é possível melhorar e de que forma. No relatório de sustentabilidade, que esta dissertação pretende desenvolver, será aplicada a metodologia sugerida pela Global Reporting Initiative (GRI). Foi ainda proposta uma metodologia de análise inovadora que permite avaliar o desempenho de sustentabilidade da empresa através do relatório de sustentabilidade elaborado. Companies and organizations in general are the fundamental movers and shakers of the economy and responsible for much of the wealth, with this value not only associated with products and services that they provide, but also with the way they develop them and the impact that their activity can have on society. In order to adapt to new times and market needs, companies are increasingly aware of the impact they can have on an economic, social and environmental level. Sustainability can be seen as a strategic aspect, which allows organizations to optimize activities and adopt a proactive and sustainable stance towards development. However, to achieve real sustainability, it is not enough to optimize and cut costs, it is also necessary to apply strategies and put measures into practice in order to guarantee the minimum levels of environmental assets, thus protecting future generations. This study aims to answer the research question: "How can the sustainability report add value to the automotive industry?", through a case study at the company Mário da Costa Martins. This study focuses on sustainable practices already in practice in the automotive industry, what and how can things in MCM be improved. The methodology suggested by the Global Reporting Initiative (GRI) will be applied on the sustainability report, which this dissertation intends to develop. A new method to evaluate firms’ sustainability performance through sustainability report was developed and presented. Dissertação de mestrado em Economia Monetária Bancária e Financeira

A sustentabilidade é um fenómeno que cada vez tem mais importância nos dias de hoje. Os consumidores estão mais informados e conscientes do impacto que as suas escolhas de consumo podem ter no ambiente e na sociedade. Em simultâneo, como resposta a estas preocupações e com o intuito de tornar o mundo num lugar melhor, as empresas sentem a necessidade de criar novas estratégias. A responsabilidade social corporativa e o “green marketing” são algumas das tendências e práticas. Estas têm, por um lado, o objetivo de minimizar o seu impacto e, por outro, o de promover um mundo mais equilibrado a nível económico, social e ambiental. Esta temática tem vindo a crescer e a apresentar novas oportunidades para as marcas. Este relatório resulta de um trabalho de pesquisa e análise desenvolvido no estágio curricular realizado entre Fevereiro de 2019 e Fevereiro de 2020 na marca Lipton, integrante da multinacional Unilever. O principal objetivo é perceber quais as estratégias da marca para promover um consumo mais responsável e sustentável. Sustainability is a phenomenon that has been becoming a very important matter nowadays. Customers are becoming highly informed and conscious about the impact that their consuming choices have on the environment and the society. Simultaneously, as an answer to these matters and to turn the world into a better place, companies are being forced to take action in order to minimize their negative impact, developing new sustainable measures. Corporate social responsibility and green marketing are some of the strategies adopted. Furthermore, companies have the goal to make this world a more economic, social and environmentally balanced one. In fact, this reality has brought an opportunity for brands to reinvent themselves. This report was emerged by an internship held for Lipton from February 2019 to February 2020, integrant brand of Unilever. The main goal is to understand which strategies were chosen to promote a responsible and sustainable consumption.

As alterações climáticas são um tema de extrema importância nos dias de hoje sendo um tópico que preocupa a população mundial. Alguns fatores humanos são responsáveis por este fenómeno, tais como a queima de combustíveis fósseis, nomeadamente a queima de petróleo, carvão ou gás que liberta CO2 e N2O para a atmosfera, o uso de fertilizantes, aumento da atividade pecuária e causas associadas à desflorestação. O impacto cada vez mais acentuado do CO2 atmosférico, assim como da temperatura, tem desencadeado um avanço de fenómenos naturais desde secas e precipitação intensa, até à evidência de perda nutricional de proteína, ferro (Fe) e zinco (Zn) em diversos vegetais, incluindo as leguminosas como soja (Glycine max. L.) e feijão (Phaseolus vulgaris L.). Em particular, as populações de países em desenvolvimento, que tenham grande dependência nas leguminosas como fontes de nutrientes, poderão vir a ser especialmente impactadas devido ao CO2 elevado. Neste projeto estudaram-se duas leguminosas, a soja cv. Thorne e o cv. Papo de rola. Realizaram-se dois ensaios: o primeiro a 400 ppm (CO2 ambiental), e o segundo a 800 ppm (valores previstos para 2050) e, em cada um destes, as plantas foram crescidas na presença e na ausência de Fe. As plantas foram mantidas em câmaras de fitoclima com temperatura, humidade e CO2 controlado. Após a recolha de dados e análise estatística percebeu-se que na soja existe um aumento do peso seco a alto CO2 (+ 52,09 % em folhas e + 60,47 % em raízes). Também se verifica que as amostras de soja e feijão que que cresceram com Fe desenvolvem-se mais (+ 67,49 % em peso seco das folhas e + 60,70 % em raízes de soja; + 91,11 % em folhas e + 77,95 % em raízes de feijão). No entanto, houve reduções na atividade da redutase férrica radicular (94,79 % em soja e 72,19 % para feijão), no teor de clorofila foliar (75,42 % em soja e 73,39 % em feijão) e na taxa fotossintética (90,46 % em soja e 58,13 % em feijão) quando comparadas com as plantas crescidas a CO2 ambiental e na ausência de Fe. Nas análises nutricionais, verifica-se maior teor proteico (55,32 %), retenção mineral (especialmente Fe e Zn), assim como, maior teor de ácidos e açúcares a CO2 ambiental com Fe. Em síntese, a soja e o feijão crescidos com Fe indicam melhores condições de sobrevivência para a planta, sendo que o maior crescimento a alto CO2 não determina necessariamente maior teor nutricional. Climate change is a topic of great importance these days being a subject of concern to the world´s population. Several human factors are responsible for this event, such as the burning of fossil fuels, namely of oil, coal or gas -that release CO2 and N2O to the atmosphere, the use of fertilizers, increased livestock production and deforestation. The increasing impact of atmospheric CO2, as well as temperature has triggered an advance of natural phenomena from droughts and intense precipitation to the evidence of nutritional loss of protein, iron (Fe) and zinc (Zn) in several plants, including legumes such as soybean (Glycine max. L.) and common bean (Phaseolus vulgaris L.). Populations in developing countries which are highly reliant on legumes as main sources of nutrients may be especially vulnerble in the future due to elevated CO2. Here, two legume grains, soybean cv. Thorne and common bean cv. Papo de rola were analyzed. Plants were grown in growth chambers, with controlled temperature, humidity and CO2. Two experiments were carried out, the first one at 400 ppm (environmental CO2) and the second at 800 ppm (values predicted for 2050). In each experiment, a set of plants grew with Fe and another set without this mineral. After data collection and statistical analysis it was observed that in soybean there is an increased dry weight at high CO2 (52.09 % in leaves and 60.47 % in roots). It is also verified that the samples of soybean and beans that grew with Fe had higher biomass (67.49 % in leaves and 60.70 % in roots of soybean; 91.11 % in leaves and 77.95 % in roots of common beans). However, there was a reduction in the activity of the root iron reductase (94.79 % in soybeans and 72.19 % in beans), in leaf chlorophyll content (75.42 % in soybean and 73.39 % in bean) and photosynthetic rate (90.46 % in soybean and 58.13 % in beans) when compared to plants that grew at ambient CO2 and in the absence of Fe. With regards to the nutritional analysis, a higher protein concentration (55.32 %), mineral retention, especially Fe and Zn, was verified, as well as a higher content of organic acids and sugars at ambient CO2 with Fe. In summary, Fe promotes better survival conditions for soybean and bean, and the higher growth at high CO2 does not reflect in higher nutritional content.
