Esta dissertação pretende ser um contributo para um conhecimento mais aprofundado sobre a importância do turismo criativo no desenvolvimento de um modelo sustentável de um destino turístico urbano. Deste modo, a dissertação desenvolve-se em três partes. A primeira centra-se numa revisão da literatura mais aprofundada sobre a criatividade e o turismo criativo com um foco específico na sustentabilidade criativa urbana. A segunda e a terceira parte concentram-se no estudo de dois casos. O primeiro, o caso de Barcelona, é um destino turístico que desenvolveu com sucesso o turismo criativo e foi reconhecido internacionalmente como boas práticas de turismo criativo sustentável. O segundo, o caso de Lisboa, é um destino que possui um grande potencial cultural e criativo. A análise observatória do estudo de caso de Barcelona permitiu apresentar uma proposta de modelo geral de turismo criativo e dar pistas a Lisboa em termos das etapas do desenvolvimento do turismo criativo, da gestão e das estratégias. A abordagem desta dissertação foca-se numa metodologia qualitativa, apoiando-se em algumas entrevistas. No que se refere aos principais resultados, descobriu-se que Lisboa apresenta as premissas para um desenvolvimento de turismo criativo. This dissertation intends to be a contribute for a better understanding of the importance of creative tourism in the development of a sustainable model of an urban tourist destination. Thus, the dissertation develops in three parts. The first concentrates on a review of the literature on creativity and creative tourism with a specific focus on urban creative sustainability. The second and the third parts aim to study two cases. The first, the case of Barcelona, is a tourist destination that has successfully developed the creative tourism and was internationally recognized for good sustainable creative tourism practices. The second, the case of Lisbon, is a destination that has a great cultural and creative potential. The observatory analysis of the case study of Barcelona has allowed to present a proposal for a general model of creative tourism and gives clues to Lisbon in terms of the stages of the development of creative tourism, management and strategies. The approach of this dissertation focuses on a qualitative methodology, relying on some interviews. With regard to the main results, it was found that Lisbon presents the assumptions for a development of creative tourism. Orientação: Jorge Mangorrinha

O turismo vai muito além da atração de turistas para destinos paradisíacos, representando uma contribuição indispensável para o desenvolvimento de um país. O crescimento deste setor torna-o cada vez mais relevante para a economia, pela sua influência em inúmeros ramos que o rodeiam. No entanto, os recursos e a infraestrutura necessária para sustentar esse enorme crescimento do setor levou a um aumento da pressão sobre os recursos naturais, a biodiversidade e as comunidades locais. Num contexto marítimo-turístico (MT) a nível nacional, observa-se um cenário dominado pelo reaproveitamento de embarcações antigas ou originalmente destinadas a outra função sem a mínima adaptação e pela utilização da mesma embarcação para diferentes tipos de programas marítimos. Por outro lado no contexto internacional, os serviços marítimo-turísticos caracterizam-se por uma enorme dependência da sazonalidade, deparando-se com uma ampla variação do nível de procura, dificultada ainda pela variação das condições climáticas ente épocas. Em comum existe uma falta de investimento e inovação na construção ou reconstrução de embarcações com fontes de energias sustentáveis e adequadas ao tipo de atividade específico onde atuam. Os objetivos da investigação procuraram preencher esta lacuna, tanto a nível de adequação da embarcação aos requisitos de cada atividade, como da adaptação às condições impostas pela sazonalidade, considerando, simultaneamente, a inclusão de estratégias sustentáveis no setor. De forma a fazer o enquadramento do tema, analisaram-se os requisitos das atividades disponibilizadas e dos respetivos utilizadores, as necessidades e limitações da embarcação, as possibilidades para a integração da modularidade, bem como as vantagens e desvantagens das fontes de propulsão e materiais possíveis. Numa fase seguinte foram analisados e selecionados os dados mais relevantes para a posterior orientação do projeto, que constitui a etapa seguinte. Nesta investigação foi projetado um modelo que poderá representar, num futuro próximo, um contributo na construção de embarcações turísticas em sistemas modulares. De forma a alcançar tais objetivos, foi aplicada uma metodologia mista, fundamentada em três metodologias de base qualitativa não intervencionista e intervencionista. Esta inicia-se com a crítica da literatura, usada na fase seguinte para formalizar e testar uma hipótese através da investigação ativa, com entrevistas e casos de estudo. De seguida passa-se para a fase intervencionista de cariz projetual com a proposta de um modelo. Aplicando esta metodologia o objetivo será a consolidação da proposta para que o resultado da investigação seja um projeto inovador que responda aos requisitos atuais do mercado. O estudo de uma embarcação turística modular e sustentável pode representar um caminho para uma solução viável e promissora neste setor, sendo a falta de inovação e investimento, a pressão ambiental e a forte sazonalidade três problemáticas tão atuais e próximas da área de investigação. ABSTRACT: Tourism goes far beyond attracting tourists to paradisiacal destinations, representing an indispensable contribution to the development of a country. The growth of this sector makes it increasingly relevant to the economy, due to its influence in numerous branches that surround it. However, the resources and infrastructure needed to sustain this huge growth in the sector has led to increased pressure on natural resources, biodiversity and local communities. In a maritime-tourist context (MT) at national level, there is a scenario dominated by the reuse of old vessels or originally intended for another function without the slightest adaptation and by the use of the same vessel for different types of maritime programs. On the other hand, in the international context, maritime-touristic services are characterized by an enormous dependence on seasonality, facing a wide variation in the level of demand, further hampered by the variation of climatic conditions between seasons. In common, there is a lack of investment and innovation in the construction or reconstruction of vessels with sustainable energy sources and appropriate to the specific type of activity in which they operate. The research objectives sought to fill this gap, both in terms of adapting the vessel to the requirements of each activity, as well as adapting to the conditions imposed by seasonality, while considering the inclusion of sustainable strategies in the sector. In order to frame the theme, the requirements of the activities provided and the respective users were analyzed, the needs and limitations of the vessel, the possibilities for integrating modularity, as well as the advantages and disadvantages of the propulsion sources and possible materials . In a next phase, the most relevant data were analyzed and selected for the later orientation of the project, which constitutes the next stage. In this investigation, a model was designed that could represent, in the near future, a contribution in the construction of tourist boats in modular systems. In order to achieve these objectives, a mixed methodology was applied, based on three non-interventionist and interventional qualitative methodologies. This begins with the criticism of the literature, used in the next phase to formalize and test a hypothesis through active investigation, with interviews and case studies. Then we move on to the interventionist phase of a design nature with the proposal of a model. Applying this methodology the objective will be the consolidation of the proposal so that the result of the investigation is an innovative project that responds to the current requirements of the market. The study of a modular and sustainable tourist vessel can represent a path to a viable and promising solution in this sector, with the lack of innovation and investment, environmental pressure and strong seasonality being three issues so current and close to the research area.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Master thesis 2024 PortugalPublisher:Instituto Superior de Economia e Gestão Authors: Silva, Viviane Conceição da;Esta dissertação investiga a implementação de uma plataforma tecnológica para monitorar métricas (Environmental, Social, and Governance - ESG) 1 no sector energético, com foco na Galp Energia, uma das principais empresas do sector em Portugal. Este estudo é motivado pela necessidade de a empresa cumprir as rigorosas exigências impostas pela nova Corporate Sustainability Reporting Directive (CSRD)2 da União Europeia. A plataforma adotada tem como objetivo centralizar e automatizar a gestão dos dados ESG, esperando melhorias na precisão, transparência e conformidade dos relatórios. A pesquisa baseia-se numa revisão de literatura que sustenta a realização de sete entrevistas com os principais responsáveis pela implementação do projeto, bem como com os futuros utilizadores da nova plataforma. Estas entrevistas são complementadas por uma análise documental fornecida pela Galp, incluindo informação detalhada sobre o processo de seleção e desenvolvimento da plataforma, relatórios institucionais e outras fontes disponíveis na internet. Da revisão de literatura aprende-se que os desafios da implementação de uma plataforma tecnológica para gestão de ESG são: a integração de dados provenientes de múltiplas fontes, a complexidade da adaptação organizacional e a necessidade de garantir a coerência entre as práticas operacionais e os requisitos regulatórios. Por outro lado, os benefícios incluem uma maior eficiência operacional, redução de custos associados à monitorização dos indicadores ESG e um fortalecimento da capacidade da empresa em gerir a sustentabilidade de forma holística e integrada. Embora a utilização de plataformas tecnológicas para a gestão de métricas ESG seja um fenómeno relativamente recente, há uma crescente quantidade de literatura que explora os seus benefícios e desafios. Contudo, devido à novidade do tema, ainda existe uma carência de bibliografia mais consolidada que permita uma análise aprofundada e abrangente do impacto destas soluções no longo prazo. Esta lacuna reforça a relevância do presente estudo, que visa contribuir para o corpo de conhecimento existente, oferecendo uma visão prática e detalhada da implementação de uma plataforma ESG numa empresa do sector energético. O estudo de caso permitiu concluir que a adoção da plataforma tecnológica poderá resultar em melhorias significativas na capacidade da Galp Energia de cumprir as exigências regulatórias e de apresentar relatórios ESG mais completos e precisos. Além disso, a utilização de uma ferramenta centralizada, se bem-sucedida após a sua implementação, poderá proporcionar uma maior agilidade na tomada de decisões estratégicas, com base em dados fiáveis e em tempo real, contribuindo para a consolidação da posição da Galp como líder em sustentabilidade no sector energético. This dissertation investigates the implementation of a technological platform for monitoring Environmental, Social, and Governance (ESG) metrics in the energy sector, focusing on Galp Energia, one of the leading companies in the sector in Portugal. This study is motivated by the need for the company to comply with the stringent requirements imposed by the European Union's new Corporate Sustainability Reporting Directive (CSRD). The adopted platform aims to centralize and automate the management of ESG data, with the expectation of improving the accuracy, transparency, and compliance of reports. The research is based on a literature review that supports seven interviews with key personnel responsible for the project’s implementation and future users of the platform, complemented by a documentary analysis provided by Galp. This documentation includes information on the selection and development process of the platform, institutional reports, and publicly available online sources. From the literature review, it is learned that the challenges of implementing a technological platform for ESG management include the integration of data from multiple sources, the complexity of organizational adaptation, and the need to ensure consistency between operational practices and regulatory requirements. On the other hand, the benefits include increased operational efficiency, reduced costs associated with monitoring ESG indicators, and enhanced company capacity to manage sustainability in a holistic and integrated manner. Although the use of technological platforms for managing ESG metrics is a relatively recent phenomenon, there is a growing body of literature that explores its benefits and challenges. However, due to the novelty of the subject, there remains a lack of more consolidated bibliographical sources that allow for a comprehensive and in-depth analysis of the long-term impact of these solutions. This gap underscores the relevance of the present study, which aims to contribute to the existing body of knowledge by offering a practical and detailed view of the implementation of an ESG platform in an energy company. The case study concluded that the adoption of the technological platform could result in significant improvements in Galp Energia's ability to meet regulatory requirements and produce more comprehensive and accurate ESG reports. Furthermore, the use of a centralized tool, if successfully implemented, could provide greater agility in strategic decision-making, based on reliable and real-time data, contributing to consolidating Galp's position as a leader in sustainability within the energy sector. info:eu-repo/semantics/publishedVersion

Mestrado em Engenharia Civil e do Ambiente na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Viana do Castelo As alterações climáticas constituem uma grande ameaça ambiental, social e económica que o mundo enfrente nos dias de hoje. O setor dos resíduos sólidos desempenha um papel importante neste combate, dado que sendo responsável por 3 a 5% das emissões dos Gases de Efeito de Estufa (GEE), de acordo com estudos da ISWA, pode contribuir com o sequestro de cerca de 13% desses gases. Os aterros sanitários, devido à composição dos resíduos depositados ser maioritariamente matéria orgânica, é uma fonte de produção de biogás, em que o metano é maioritário, sendo 21 a 25 vezes (dados do IPCC) mais nefasto para a atmosfera que o dióxido de carbono, o outro constituinte maioritário do biogás. Assim, a extração do biogás em aterros sanitários e a sua queima constitui uma das medidas mais efetivas para a diminuição do risco e no combate às alterações climáticas. Os resíduos urbanos dos 6 municípios da RESULIMA depositam cerca de 356 t/dia de resíduos urbanos (2015). A desgaseificação é feita através de poços, normalmente implantados considerando um raio de influência de desgaseificação de cada poço de 25 metros. No entanto, tem-se verificado que as emissões também se processam através das camadas de cobertura fora da ação destes poços e, sobretudo, durante a exploração, através das coberturas provisórias ou intermédias realizadas com terras e que importa quantificar. No presente trabalho foram realizadas medições contínuas do biogás nos diversos poços de desgaseificação para avaliar a evolução quantitativa e qualitativa de geração de biogás no aterro, com o tempo. Também se analisaram os dados históricos do biogás, que a empresa RESULIMA detém, em complemento dos dados obtidos no decurso dos trabalhos. Numa segunda etapa, com o objetivo de avaliar o efeito barreira à passagem de gases das coberturas intermédias, procedeu-se à medição das emissões fugidias do biogás com câmara de fluxo em diversos pontos do topo do aterro, com espessuras diferentes, constatando-se que a eficiência à passagem de gases das camadas de coberturas intermédias depende do material e da espessura do mesmo, bem como do modo de operação do aterro, de que se salienta o grau de compactação. Climate change is currently a major environmental, social and economic threat which the world is facing. The solid waste sector plays an important role in this fight as, according to ISWA studies, it accounts for 3 to 5% of the greenhouse gas emissions (GHG) and can contribute to the sequestration of about 13% of these gases. Due to the fact that deposited waste is mainly composed of organic matter, landfills are a source of biogas production, most of which is methane, which makes it 21 to 25 times (IPCC data) more harmful to the atmosphere than carbon dioxide, the other major constituent of biogas. Therefore, the extraction of biogas from landfills and its burning is one of the most effective measures for reducing risks and fighting climate change. The 6 municipalities of RESULIMA deposit around 356 t / day of urban waste (2015). The degassing is done by means of wells that are usually implanted considering a 25-metre radius of influence of degassing of each well. However, it has been found that the emissions are also processed through the cover layers beyond the action of these wells and, especially during the study, through the temporary or intermediate covers carried out with soil, which it is also important to quantify. Throughout this study, continuous measurements of the biogas were carried out in the various degassing wells to evaluate the quantitative and qualitative evolution of biogas generation in the landfill over time. The historical biogas data that RESULIMA owns was also analysed, in addition to the information obtained during the study. During a second phase, with the aim of evaluating the barrier effect of the passage of gases from the intermediate cover layers, the fleeting emissions of the biogas were measured with a chamber gas-flow meter at several points of the top of the landfill, with different thicknesses, which led to the conclusion that the gas flow efficiency of the intermediate cover layers depends on the material and the thickness thereof, as well as on the operation mode and compactness of the landfill.

Este trabalho teve como objectivo avaliar a viabilidade de produção de biodiesel pelo processo de hidroesterificação utilizando como matéria-prima os óleos alimentares usados produzidos nos estabelecimentos hoteleiros e de restauração na ilha de São Vicente. Apesar de o biodiesel apresentar-se uma alternativa promissora como combustível, para substituição do diesel mineral, ocasiona alguns problemas no processo convencional de produção, transesterificação, que requer matérias-primas com baixo teor em humidade e acidez, o que não permite que matérias-primas de baixo custo como o óleo alimentar usado sejam uma opção promissora na rota produtiva. Por outro lado, o processo de hidroesterificação permite o uso de quaisquer matérias-primas independentemente do teor em humidade e acidez. Inicialmente foi realizado uma pesquisa de campo para avaliar a quantidade de resíduo de óleo gerado pelos estabelecimentos comerciais de São Vicente e se os mesmos estariam dispostos a doarem o óleo alimentar usado a uma entidade de recolha para fins recicláveis. Dos 40 estabelecimentos comerciais entrevistados, todos mostraram-se disponíveis em entregar o óleo à entidade recolhedora. Depois prosseguiu-se a produção do biodiesel em escala laboratorial para analisar as opções de produção pelo processo de transesterificação em 2 etapas e pela hidroesterificação como forma a verificar a melhor rota produtiva. Os resultados obtidos mostraram que o biodiesel obtido a partir da transesterificação do óleo alimentar usado apresentou um rendimento reacional de 67,2% em massa e o biodiesel obtido a partir de hidroesterificação do óleo alimentar usado apresentou um rendimento reacional de 78 % em massa. Para converter os óleos alimentares usados em biodiesel pela hidroesterificação será necessário um investimento para implementação de uma fábrica com capacidade de 7.920L/mês no valor de 3.783.499$00ECV. Baseando em um rendimento otimizado do processo da fábrica de 85% de produção de biodiesel e 10% de glicerina foi estimado o custo de produção de 1L de biodiesel no valor de 211$00ECV.

Silva; Catarino, Justina; Camocho, David; Alexandre, Jorge;RESUMO: O objectivo da Enterprise Europe Network é ajudar as empresas a inovar e a competir melhor internacionalmente. As empresas que pretendam inovar e competir podem estabelecer parcerias com as suas congéneres estrangeiras utilizando esta rede. Necessitam também de instrumentos que lhes permitam avaliar o seu desempenho. As crescentes preocupações com o Desenvolvimento Sustentável levaram ao progressivo reequacionamento das atividades empresariais tendo em conta os aspetos ambientais e sociais e não apenas os tradicionalmente utilizados na avaliação do desempenho das empresas, essencialmente os económicos e técnicos. É assim que surge a necessidade de uma atualização da metologia da Análise do Valor, passando a integrar os componentes da Sustentabilidade na definição de Valor Sustentável. O Valor Ssutentável, proposto nesta brochura, é um indicador calculado a partir da relação desempenho versus recursos envolvidos de modo a garantir esse desempenho. Tem em linha de conta a tripla linha de base da sustentabilidade e não apenas interesses economicistas contribuindo também para a circularidade da economia. ABSTRACT: The aim of the Enterprise Europe Network is to help companies innovate and compete better internationally. Companies wishing to innovate and compete can establish partnerships with their foreign counterparts using this network. Bust they also need instruments that allow them to assess their performance. The growing concerns with Sustainable Development have led to the progressive re-alignment of business activities taking into account environmental and social aspects and not just those traditionally used in assessing the performance of companies, essentially economic and technical. This led to the need of updating the Value Analysis methodology, integrating the components of Sustainability in the definition of Sustainable Value. The Sustainable Value, proposed in this brochure, is an indicator calculated based on the performance versus resources involved in order to guarantee this performance. It takes into account the triple baseline os sustainability and not only economic interest, also contributing to circularity of the economy. info:eu-repo/semantics/publishedVersion

The manufacture process of biodiesel produces approximately 10% glycerin, the main byproduct. Due to the growth of the biodiesel industry in Brazil and abroad, the high volumes of glycerin become a bottleneck in this chain, given that currently use the glycerin market serves a very narrow and specific. Many efforts have been directed to find strategic alternatives for the sustainable use of biodiesel derived glycerin. The competitiveness of the production chain, which originates with the glycerin byproduct of the manufacture of biodiesel, has as one of its determinants identifying technological routes and products to intensify the consumption of this product. In this dissertation, the goal was to determine how it is being done to manage technological innovation and progress in the identification and discussion of the influence which the glycerin is delivering on the biodiesel production chain, seeking possible ways to increase both competitiveness of Brazilian production chain glycerin and biodiesel. To achieve this, interviews were conducted with biodiesel producers, producers and consumers of glycerin and laboratories and research institutes. These interviews were conducted with the aid of a semi-structured questionnaire.

Esta dissertação pretende ser um contributo para um conhecimento mais aprofundado sobre a importância do turismo criativo no desenvolvimento de um modelo sustentável de um destino turístico urbano. Deste modo, a dissertação desenvolve-se em três partes. A primeira centra-se numa revisão da literatura mais aprofundada sobre a criatividade e o turismo criativo com um foco específico na sustentabilidade criativa urbana. A segunda e a terceira parte concentram-se no estudo de dois casos. O primeiro, o caso de Barcelona, é um destino turístico que desenvolveu com sucesso o turismo criativo e foi reconhecido internacionalmente como boas práticas de turismo criativo sustentável. O segundo, o caso de Lisboa, é um destino que possui um grande potencial cultural e criativo. A análise observatória do estudo de caso de Barcelona permitiu apresentar uma proposta de modelo geral de turismo criativo e dar pistas a Lisboa em termos das etapas do desenvolvimento do turismo criativo, da gestão e das estratégias. A abordagem desta dissertação foca-se numa metodologia qualitativa, apoiando-se em algumas entrevistas. No que se refere aos principais resultados, descobriu-se que Lisboa apresenta as premissas para um desenvolvimento de turismo criativo. This dissertation intends to be a contribute for a better understanding of the importance of creative tourism in the development of a sustainable model of an urban tourist destination. Thus, the dissertation develops in three parts. The first concentrates on a review of the literature on creativity and creative tourism with a specific focus on urban creative sustainability. The second and the third parts aim to study two cases. The first, the case of Barcelona, is a tourist destination that has successfully developed the creative tourism and was internationally recognized for good sustainable creative tourism practices. The second, the case of Lisbon, is a destination that has a great cultural and creative potential. The observatory analysis of the case study of Barcelona has allowed to present a proposal for a general model of creative tourism and gives clues to Lisbon in terms of the stages of the development of creative tourism, management and strategies. The approach of this dissertation focuses on a qualitative methodology, relying on some interviews. With regard to the main results, it was found that Lisbon presents the assumptions for a development of creative tourism. Orientação: Jorge Mangorrinha

O turismo vai muito além da atração de turistas para destinos paradisíacos, representando uma contribuição indispensável para o desenvolvimento de um país. O crescimento deste setor torna-o cada vez mais relevante para a economia, pela sua influência em inúmeros ramos que o rodeiam. No entanto, os recursos e a infraestrutura necessária para sustentar esse enorme crescimento do setor levou a um aumento da pressão sobre os recursos naturais, a biodiversidade e as comunidades locais. Num contexto marítimo-turístico (MT) a nível nacional, observa-se um cenário dominado pelo reaproveitamento de embarcações antigas ou originalmente destinadas a outra função sem a mínima adaptação e pela utilização da mesma embarcação para diferentes tipos de programas marítimos. Por outro lado no contexto internacional, os serviços marítimo-turísticos caracterizam-se por uma enorme dependência da sazonalidade, deparando-se com uma ampla variação do nível de procura, dificultada ainda pela variação das condições climáticas ente épocas. Em comum existe uma falta de investimento e inovação na construção ou reconstrução de embarcações com fontes de energias sustentáveis e adequadas ao tipo de atividade específico onde atuam. Os objetivos da investigação procuraram preencher esta lacuna, tanto a nível de adequação da embarcação aos requisitos de cada atividade, como da adaptação às condições impostas pela sazonalidade, considerando, simultaneamente, a inclusão de estratégias sustentáveis no setor. De forma a fazer o enquadramento do tema, analisaram-se os requisitos das atividades disponibilizadas e dos respetivos utilizadores, as necessidades e limitações da embarcação, as possibilidades para a integração da modularidade, bem como as vantagens e desvantagens das fontes de propulsão e materiais possíveis. Numa fase seguinte foram analisados e selecionados os dados mais relevantes para a posterior orientação do projeto, que constitui a etapa seguinte. Nesta investigação foi projetado um modelo que poderá representar, num futuro próximo, um contributo na construção de embarcações turísticas em sistemas modulares. De forma a alcançar tais objetivos, foi aplicada uma metodologia mista, fundamentada em três metodologias de base qualitativa não intervencionista e intervencionista. Esta inicia-se com a crítica da literatura, usada na fase seguinte para formalizar e testar uma hipótese através da investigação ativa, com entrevistas e casos de estudo. De seguida passa-se para a fase intervencionista de cariz projetual com a proposta de um modelo. Aplicando esta metodologia o objetivo será a consolidação da proposta para que o resultado da investigação seja um projeto inovador que responda aos requisitos atuais do mercado. O estudo de uma embarcação turística modular e sustentável pode representar um caminho para uma solução viável e promissora neste setor, sendo a falta de inovação e investimento, a pressão ambiental e a forte sazonalidade três problemáticas tão atuais e próximas da área de investigação. ABSTRACT: Tourism goes far beyond attracting tourists to paradisiacal destinations, representing an indispensable contribution to the development of a country. The growth of this sector makes it increasingly relevant to the economy, due to its influence in numerous branches that surround it. However, the resources and infrastructure needed to sustain this huge growth in the sector has led to increased pressure on natural resources, biodiversity and local communities. In a maritime-tourist context (MT) at national level, there is a scenario dominated by the reuse of old vessels or originally intended for another function without the slightest adaptation and by the use of the same vessel for different types of maritime programs. On the other hand, in the international context, maritime-touristic services are characterized by an enormous dependence on seasonality, facing a wide variation in the level of demand, further hampered by the variation of climatic conditions between seasons. In common, there is a lack of investment and innovation in the construction or reconstruction of vessels with sustainable energy sources and appropriate to the specific type of activity in which they operate. The research objectives sought to fill this gap, both in terms of adapting the vessel to the requirements of each activity, as well as adapting to the conditions imposed by seasonality, while considering the inclusion of sustainable strategies in the sector. In order to frame the theme, the requirements of the activities provided and the respective users were analyzed, the needs and limitations of the vessel, the possibilities for integrating modularity, as well as the advantages and disadvantages of the propulsion sources and possible materials . In a next phase, the most relevant data were analyzed and selected for the later orientation of the project, which constitutes the next stage. In this investigation, a model was designed that could represent, in the near future, a contribution in the construction of tourist boats in modular systems. In order to achieve these objectives, a mixed methodology was applied, based on three non-interventionist and interventional qualitative methodologies. This begins with the criticism of the literature, used in the next phase to formalize and test a hypothesis through active investigation, with interviews and case studies. Then we move on to the interventionist phase of a design nature with the proposal of a model. Applying this methodology the objective will be the consolidation of the proposal so that the result of the investigation is an innovative project that responds to the current requirements of the market. The study of a modular and sustainable tourist vessel can represent a path to a viable and promising solution in this sector, with the lack of innovation and investment, environmental pressure and strong seasonality being three issues so current and close to the research area.

Este estudo é motivado pela necessidade de a empresa cumprir as rigorosas exigências impostas pela nova Corporate Sustainability Reporting Directive (CSRD)2 da União Europeia. A plataforma adotada tem como objetivo centralizar e automatizar a gestão dos dados ESG, esperando melhorias na precisão, transparência e conformidade dos relatórios. A pesquisa baseia-se numa revisão de literatura que sustenta a realização de sete entrevistas com os principais responsáveis pela implementação do projeto, bem como com os futuros utilizadores da nova plataforma. Estas entrevistas são complementadas por uma análise documental fornecida pela Galp, incluindo informação detalhada sobre o processo de seleção e desenvolvimento da plataforma, relatórios institucionais e outras fontes disponíveis na internet. Da revisão de literatura aprende-se que os desafios da implementação de uma plataforma tecnológica para gestão de ESG são: a integração de dados provenientes de múltiplas fontes, a complexidade da adaptação organizacional e a necessidade de garantir a coerência entre as práticas operacionais e os requisitos regulatórios. Por outro lado, os benefícios incluem uma maior eficiência operacional, redução de custos associados à monitorização dos indicadores ESG e um fortalecimento da capacidade da empresa em gerir a sustentabilidade de forma holística e integrada. Embora a utilização de plataformas tecnológicas para a gestão de métricas ESG seja um fenómeno relativamente recente, há uma crescente quantidade de literatura que explora os seus benefícios e desafios. Contudo, devido à novidade do tema, ainda existe uma carência de bibliografia mais consolidada que permita uma análise aprofundada e abrangente do impacto destas soluções no longo prazo. Esta lacuna reforça a relevância do presente estudo, que visa contribuir para o corpo de conhecimento existente, oferecendo uma visão prática e detalhada da implementação de uma plataforma ESG numa empresa do sector energético. O estudo de caso permitiu concluir que a adoção da plataforma tecnológica poderá resultar em melhorias significativas na capacidade da Galp Energia de cumprir as exigências regulatórias e de apresentar relatórios ESG mais completos e precisos. Além disso, a utilização de uma ferramenta centralizada, se bem-sucedida após a sua implementação, poderá proporcionar uma maior agilidade na tomada de decisões estratégicas, com base em dados fiáveis e em tempo real, contribuindo para a consolidação da posição da Galp como líder em sustentabilidade no sector energético. This dissertation investigates the implementation of a technological platform for monitoring Environmental, Social, and Governance (ESG) metrics in the energy sector, focusing on Galp Energia, one of the leading companies in the sector in Portugal. This study is motivated by the need for the company to comply with the stringent requirements imposed by the European Union's new Corporate Sustainability Reporting Directive (CSRD). The adopted platform aims to centralize and automate the management of ESG data, with the expectation of improving the accuracy, transparency, and compliance of reports. The research is based on a literature review that supports seven interviews with key personnel responsible for the project’s implementation and future users of the platform, complemented by a documentary analysis provided by Galp. This documentation includes information on the selection and development process of the platform, institutional reports, and publicly available online sources. From the literature review, it is learned that the challenges of implementing a technological platform for ESG management include the integration of data from multiple sources, the complexity of organizational adaptation, and the need to ensure consistency between operational practices and regulatory requirements. On the other hand, the benefits include increased operational efficiency, reduced costs associated with monitoring ESG indicators, and enhanced company capacity to manage sustainability in a holistic and integrated manner. Although the use of technological platforms for managing ESG metrics is a relatively recent phenomenon, there is a growing body of literature that explores its benefits and challenges. However, due to the novelty of the subject, there remains a lack of more consolidated bibliographical sources that allow for a comprehensive and in-depth analysis of the long-term impact of these solutions. This gap underscores the relevance of the present study, which aims to contribute to the existing body of knowledge by offering a practical and detailed view of the implementation of an ESG platform in an energy company. The case study concluded that the adoption of the technological platform could result in significant improvements in Galp Energia's ability to meet regulatory requirements and produce more comprehensive and accurate ESG reports. Furthermore, the use of a centralized tool, if successfully implemented, could provide greater agility in strategic decision-making, based on reliable and real-time data, contributing to consolidating Galp's position as a leader in sustainability within the energy sector. info:eu-repo/semantics/publishedVersion

These projects are generally materialized in specialized institutions in the development of high-level scientific solutions aimed at increasing intellectual and material corporate, governmental or social power. Within organizations, in view of the current increasingly globalized competitiveness, the decision-making process is fundamental. In this perspective of search for continuous improvement, it is essential the vision of the future by managers and researchers as well as the industry, so that they work integrated and articulated. In addition, governments and companies have suffered from political and economic crises that, with the use of techniques such as structural analysis and strategic prospecting, would be possible to be premeditated and better managed. Therefore, this dissertation project proposes an approach to scenario exploration for the Institute for Smart Grids at Federal University of Santa Maria, which carries out research, development and innovation activities. This research is based on a bibliographical and documentary review on the characteristics of the sector, competitive intelligence and scenario exploration.

Mestrado em Engenharia Civil e do Ambiente na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Viana do Castelo As alterações climáticas constituem uma grande ameaça ambiental, social e económica que o mundo enfrente nos dias de hoje. O setor dos resíduos sólidos desempenha um papel importante neste combate, dado que sendo responsável por 3 a 5% das emissões dos Gases de Efeito de Estufa (GEE), de acordo com estudos da ISWA, pode contribuir com o sequestro de cerca de 13% desses gases. Os aterros sanitários, devido à composição dos resíduos depositados ser maioritariamente matéria orgânica, é uma fonte de produção de biogás, em que o metano é maioritário, sendo 21 a 25 vezes (dados do IPCC) mais nefasto para a atmosfera que o dióxido de carbono, o outro constituinte maioritário do biogás. Assim, a extração do biogás em aterros sanitários e a sua queima constitui uma das medidas mais efetivas para a diminuição do risco e no combate às alterações climáticas. Os resíduos urbanos dos 6 municípios da RESULIMA depositam cerca de 356 t/dia de resíduos urbanos (2015). A desgaseificação é feita através de poços, normalmente implantados considerando um raio de influência de desgaseificação de cada poço de 25 metros. No entanto, tem-se verificado que as emissões também se processam através das camadas de cobertura fora da ação destes poços e, sobretudo, durante a exploração, através das coberturas provisórias ou intermédias realizadas com terras e que importa quantificar. No presente trabalho foram realizadas medições contínuas do biogás nos diversos poços de desgaseificação para avaliar a evolução quantitativa e qualitativa de geração de biogás no aterro, com o tempo. Também se analisaram os dados históricos do biogás, que a empresa RESULIMA detém, em complemento dos dados obtidos no decurso dos trabalhos. Numa segunda etapa, com o objetivo de avaliar o efeito barreira à passagem de gases das coberturas intermédias, procedeu-se à medição das emissões fugidias do biogás com câmara de fluxo em diversos pontos do topo do aterro, com espessuras diferentes, constatando-se que a eficiência à passagem de gases das camadas de coberturas intermédias depende do material e da espessura do mesmo, bem como do modo de operação do aterro, de que se salienta o grau de compactação. Climate change is currently a major environmental, social and economic threat which the world is facing. The solid waste sector plays an important role in this fight as, according to ISWA studies, it accounts for 3 to 5% of the greenhouse gas emissions (GHG) and can contribute to the sequestration of about 13% of these gases. Due to the fact that deposited waste is mainly composed of organic matter, landfills are a source of biogas production, most of which is methane, which makes it 21 to 25 times (IPCC data) more harmful to the atmosphere than carbon dioxide, the other major constituent of biogas. Therefore, the extraction of biogas from landfills and its burning is one of the most effective measures for reducing risks and fighting climate change. The 6 municipalities of RESULIMA deposit around 356 t / day of urban waste (2015). The degassing is done by means of wells that are usually implanted considering a 25-metre radius of influence of degassing of each well. However, it has been found that the emissions are also processed through the cover layers beyond the action of these wells and, especially during the study, through the temporary or intermediate covers carried out with soil, which it is also important to quantify. Throughout this study, continuous measurements of the biogas were carried out in the various degassing wells to evaluate the quantitative and qualitative evolution of biogas generation in the landfill over time. The historical biogas data that RESULIMA owns was also analysed, in addition to the information obtained during the study. During a second phase, with the aim of evaluating the barrier effect of the passage of gases from the intermediate cover layers, the fleeting emissions of the biogas were measured with a chamber gas-flow meter at several points of the top of the landfill, with different thicknesses, which led to the conclusion that the gas flow efficiency of the intermediate cover layers depends on the material and the thickness thereof, as well as on the operation mode and compactness of the landfill.

Este trabalho teve como objectivo avaliar a viabilidade de produção de biodiesel pelo processo de hidroesterificação utilizando como matéria-prima os óleos alimentares usados produzidos nos estabelecimentos hoteleiros e de restauração na ilha de São Vicente. Apesar de o biodiesel apresentar-se uma alternativa promissora como combustível, para substituição do diesel mineral, ocasiona alguns problemas no processo convencional de produção, transesterificação, que requer matérias-primas com baixo teor em humidade e acidez, o que não permite que matérias-primas de baixo custo como o óleo alimentar usado sejam uma opção promissora na rota produtiva. Por outro lado, o processo de hidroesterificação permite o uso de quaisquer matérias-primas independentemente do teor em humidade e acidez. Inicialmente foi realizado uma pesquisa de campo para avaliar a quantidade de resíduo de óleo gerado pelos estabelecimentos comerciais de São Vicente e se os mesmos estariam dispostos a doarem o óleo alimentar usado a uma entidade de recolha para fins recicláveis. Dos 40 estabelecimentos comerciais entrevistados, todos mostraram-se disponíveis em entregar o óleo à entidade recolhedora. Depois prosseguiu-se a produção do biodiesel em escala laboratorial para analisar as opções de produção pelo processo de transesterificação em 2 etapas e pela hidroesterificação como forma a verificar a melhor rota produtiva. Os resultados obtidos mostraram que o biodiesel obtido a partir da transesterificação do óleo alimentar usado apresentou um rendimento reacional de 67,2% em massa e o biodiesel obtido a partir de hidroesterificação do óleo alimentar usado apresentou um rendimento reacional de 78 % em massa. Para converter os óleos alimentares usados em biodiesel pela hidroesterificação será necessário um investimento para implementação de uma fábrica com capacidade de 7.920L/mês no valor de 3.783.499$00ECV. Baseando em um rendimento otimizado do processo da fábrica de 85% de produção de biodiesel e 10% de glicerina foi estimado o custo de produção de 1L de biodiesel no valor de 211$00ECV.

Silva; Catarino, Justina; Camocho, David; Alexandre, Jorge;RESUMO: O objectivo da Enterprise Europe Network é ajudar as empresas a inovar e a competir melhor internacionalmente. As empresas que pretendam inovar e competir podem estabelecer parcerias com as suas congéneres estrangeiras utilizando esta rede. Necessitam também de instrumentos que lhes permitam avaliar o seu desempenho. As crescentes preocupações com o Desenvolvimento Sustentável levaram ao progressivo reequacionamento das atividades empresariais tendo em conta os aspetos ambientais e sociais e não apenas os tradicionalmente utilizados na avaliação do desempenho das empresas, essencialmente os económicos e técnicos. É assim que surge a necessidade de uma atualização da metologia da Análise do Valor, passando a integrar os componentes da Sustentabilidade na definição de Valor Sustentável. O Valor Ssutentável, proposto nesta brochura, é um indicador calculado a partir da relação desempenho versus recursos envolvidos de modo a garantir esse desempenho. Tem em linha de conta a tripla linha de base da sustentabilidade e não apenas interesses economicistas contribuindo também para a circularidade da economia. ABSTRACT: The aim of the Enterprise Europe Network is to help companies innovate and compete better internationally. Companies wishing to innovate and compete can establish partnerships with their foreign counterparts using this network. Bust they also need instruments that allow them to assess their performance. The growing concerns with Sustainable Development have led to the progressive re-alignment of business activities taking into account environmental and social aspects and not just those traditionally used in assessing the performance of companies, essentially economic and technical. This led to the need of updating the Value Analysis methodology, integrating the components of Sustainability in the definition of Sustainable Value. The Sustainable Value, proposed in this brochure, is an indicator calculated based on the performance versus resources involved in order to guarantee this performance. It takes into account the triple baseline os sustainability and not only economic interest, also contributing to circularity of the economy. info:eu-repo/semantics/publishedVersion

The manufacture process of biodiesel produces approximately 10% glycerin, the main byproduct. Due to the growth of the biodiesel industry in Brazil and abroad, the high volumes of glycerin become a bottleneck in this chain, given that currently use the glycerin market serves a very narrow and specific. Many efforts have been directed to find strategic alternatives for the sustainable use of biodiesel derived glycerin. The competitiveness of the production chain, which originates with the glycerin byproduct of the manufacture of biodiesel, has as one of its determinants identifying technological routes and products to intensify the consumption of this product. In this dissertation, the goal was to determine how it is being done to manage technological innovation and progress in the identification and discussion of the influence which the glycerin is delivering on the biodiesel production chain, seeking possible ways to increase both competitiveness of Brazilian production chain glycerin and biodiesel. To achieve this, interviews were conducted with biodiesel producers, producers and consumers of glycerin and laboratories and research institutes. These interviews were conducted with the aid of a semi-structured questionnaire. A documentary analysis on patents involving the object of study was also performed to verify the main uses found for glycerin. With this, through a chain mapping of glycerol, was described and analyzed the dynamics of their operation and also identified the players who participate directly and indirectly, as well as the productive chains of biodiesel and glycerin are dealing with the management technological innovation aimed at the production thereof.
