description Publicationkeyboard_double_arrow_right Conference object 2013 FrancePublisher:D.M. HOGARTH Authors: Chopart, Jean-Louis; Bonnal, Laurent; Martiné, Jean-François; Sabatier, Daniel;Two studies conducted in Guadeloupe (West Indies) and Réunion (Indian Ocean) islands were designed to investigate the benefits of producing sugarcane as an energy crop and to assess the influence of agroclimatic factors on energy efficiency, respectively. In this context, it is essential to know the low heating value of the dry above-ground biomass (LHVd, MJ/kg) and its energy yield (EY, MJ/m2) in order to select the best varieties and set up a payment method for growers. Eighteen Poaceae (sugarcane and Erianthus) cultivars were compared under wet tropical environmental conditions in Guadeloupe. Three sugarcane cultivars were studied in four contrasting environments in Réunion. The partition sampling and biomass measurement procedures were identical at both locations. Low heating value (LHV) predictions were achieved using near-infrared reflectance spectroscopy (NIRS) after specific calibration (Guadeloupe), or arithmetically after lignocellulosic compound prediction (Réunion). In both studies, LHV variability was very low and slightly dependent on the site, cultivar and above-ground biomass components (millable stalks and tops, and green and dead leaves). Considering the overall dry above-ground biomass (DAB, kg/m2), the LHVd was calculated by averaging 159 samples (mean 16.65 MJ/kg) in Guadeloupe and 315 samples (mean 16.45 MJ/kg) for Réunion. An excellent linear relationship between the DAB and its EY, regardless of cultivar, age and environment, was found (n = 474 and R² = 0.99). Sugarcane energy content assessment could thus be simplified by measuring the DAB, while enabling development of a faster method of payment for growers based on the DAB measurement and the correlation between DAB and EY. Finally, the findings of this study should allow growers to rapidly determine the commercial value of their sugarcane crops, and also enable purchasers to assess the amount of recoverable energy.

The importance of emission control has increased sharply due to increased need of energy from combustion. However, biomass utilization in energy production is not free from problems because of physical and chemical characteristics which are substantially different from conventional energy sources. In this situation, the quantity and quality of emissions as well as used renewable source as wood or corn grain are often unknown. To assess this problem the paper addresses the objectives to quantify the amount of greenhouse gases during the combustion of corn as compared to the emissions in fossil combustion (natural gas, LPG and diesel boiler). The test was carried out in Friuli Venezia Giulia in 2006-2008 to determine the air pollution (CO, NO, NO2, NOx, SO2 and CO2) from fuel combustion in the family boilers with power between 20-30 kWt. The flue gas emission was measured with a professional semi-continuous multi-gas analyzer, (Vario plus industrial, MRU air Neckarsulm-Obereisesheim). Data showed a lower emission of fossil fuel compared to corn in family boilers in reference to pollutants in the flue gas (NOx, SO2 and CO). In particular way the biomass combustion make a higher concentration of carbon monoxide (for a incomplete combustion because there aren’t a good mixing between fuel and air) and nitrogen oxides (in relation at higher content of nitrogen in herbaceous biomass in comparison of another fuel).

In the past concrete industry has satisfied these needs well. However, for a variety of reasons, the situation has changed dramatically in the last years. First of all, the concrete industry is the largest consumer of natural resources. Secondly, Portland cement, the binder of modern concrete mixtures, is not as environmentally friendly. The world's cement production, in fact, contributes to the earth's atmosphere about 7% of the total CO2 emissions, CO2 being one of the primary greenhouse gas (GHG) responsible for global warming and climate change. As a consequence, concrete industry in the future has to face two antithetically needs. In other words, how the concrete industry can feed the growing population needs being - at the same time - sustainable? The answer to this question is represented by the ?3R-Green Strategy? widely discussed in the first chapter of this PhD thesis: Reduction in consumption of gross energy for construction materials production, Reduction in polluting emissions and Reduction in consuming not renewable natural resources. In particular, this thesis is focused on the alternative binders to Portland cement such as alkali-activated slag cements and calcium sulphoaluminate cement-based binders in order to manufacture sustainable mixtures for special applications such as repair mortars, lightweight reinforced plasters and concretes for slabs on ground. The experimental results show the feasibility of manufacturing both EN 1504-3 R3 class mortars and Portland-free concretes for jointless slabs on ground with calcium sulphoaluminate cement, supplementary cementitious materials (fly ash, ground granulated blast furnace slag) and hydrated lime instead of Portland cement. Moreover, alkali-activated mortars and concretes seem to be a reasonable alternative to natural hydraulic lime-based and/or traditional Portland cement-based mixtures for rehabilitation or restoration of ancient masonry buildings and existing concretes structures. Finally, a new sustainability index was developed taking into account the environmental impact, the performances and the durability of mixtures. In particular, in the environmental impact section, the natural raw materials consumption, the greenhouse gas emissions and the energy consumption have been considered. Furthermore, depending on the applications and the environments, design parameters and properties related to durability have been assigned to each mixture. less

The current fashion design, production, and consumption system, known as ‘fast fashion’, is characterized by the manufacturing of low-quality garments in a short period of time carried out in developing countries. In parallel with the deficits in social responsibility and human rights, the prevailing ‘take-make-dispose’ system in the fashion industry is one of the main causes of environmental pollution that concerns the climate change, scarcity of natural resources and health problems for the living beings. Due to these facts, discussions on Circular Design strategies – for waste reduction, components recycling, and materials reuse – became increasingly relevant throughout the globe. This paper’s aspiration is to outline a perspective towards a Circular Fashion. The concept of the Design for Sustainability requires a holistic view throughout de-signing strategies as well as the establishment of cyclical systems for the production site. Notwithstanding, the efficient integration of social and cultural dimensions are vital for Sustainable Fashion’s triumph.

Bioethanol appears to be one potential solution, especially second-generation production from renewable biomass.In order to use lignocellulosic feedstock to produce bioethanol, its polysaccharide components, cellulose and hemicellulose, must be hydrolysed into soluble sugars, which can then be converted into ethanol by fermentative microorganisms such as Geobacillus thermoglucosidasius TM242 used by the company ReBio Technologies Ltd.To date, the cost of commercial enzymes used during the hydrolysis process remains a major economic consideration in the production of second-generation bioethanol as an alternative fuel. The research project presented in this thesis aims to improve this rate-limiting step of microbial bioethanol production through an investigation of the different enzymes associated with hemicellulose hydrolysis. Firstly, the TM242 genome sequence revealed a number of genes encoding glycoside-hydrolases. Six of these genes were cloned and expressed in E. coli and the recombinant enzymes characterised; three of them, two β-xylosidases and an α arabinofuranosidase, are relevant to xylan hydrolysis, and were found to be highly active and thermostable. Crystallisation of one of the β-xylosidases permitted the determination of a high-resolution (1.7 Å) structure of the apo-enzyme along with a lower resolution (2.6 Å) structure of the enzyme-substrate complex, resulting in the first reported structure of a GH52 family member (Espina et al., 2014).Secondly, as the TM242 microorganism lacks xylanase enzymes, four genes encoding xylanases from closely-related Geobacillus strains were cloned and expressed in E. coli, with one of them being also successfully cloned and expressed in G. thermoglucosidasius TM242. This heterologous xylanase was secreted in active form representing an enhanced biomass utilisation by TM242.In conclusion, it is felt that the findings presented here have the potential to make a valuable contribution towards second-generation bioethanol production.

Reducing agronomic input supply can significantly contribute to decrease the environmental impact of bioenergy cropping systems. Currently, there is a renewed industrial interest in non-food oil crops for different end-uses application. Among species from Brassica genus, Brassica carinata A. Braun is an interesting winter annual crop in warm and semi-arid environments and may provide a rotation alternative with cereal crops, sourcing non-edible oil for the industry, additional incomes to the farmers and soil benefits. The present study compared four Brassica carinata lines (GID-6165, GIP-6164, GID-6091, GID-6084) under two different organic fertilization levels (80 and 160 kg N ha-1) in a semiarid Mediterranean area. These four lines have not been tested in Southern Italy previously, nor under the present low-input cultivation practices in semiarid Mediterranean area. Main findings showed a significant fertilization effect (P=0.05), with the high-input providing higher seed yields and harvest index than low-input. There was no genotype effect, however, the gap between potential (i.e. seed yield at the programmed plant density) and actual yields was rather high for GID-6165 and GID-6080. On the other hand, genotype had the largest effect on the thousand seed weight and the residual biomass yield. In general, GID-6091 and GID-6165 reached seed physiological maturity earlier than GID-6084 and GID-6164 lines. The present study proved that improved B. carinata lines can be grown in semiarid Mediterranean area under low-input organic systems, providing satisfactory seed yields. However, seedbed preparation was noticed to be key to narrow the gap between potential and actual seed yield, particularly under the present clay soil.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Conference object 2023 TurkeyPublisher:Bilgesina Yayınevi Authors: Deviren, Halis; Aydın, Hüseyin;The high level of emissions and pollution caused by diesel engines increases the importance of developing low-emission and high-efficiency fuel technologies. Implementing various modifications in engines has the potential to reduce emissions, however, these adjustments can lead to technical difficulties and inefficiencies in terms of cost. In this case, as an alternative solution, the use of diesel fuel (DF), biodiesel (B100), nanoparticle and light or heavy alcohol mixtures can be considered; these fuels can help engines produce less polluting emissions. As it is known, the main reason why internal combustion engines emit emissions such as particulate matter, hydrocarbon (HC), and carbon monoxide (CO) into the atmosphere is incomplete combustion of the fuel. The high oxygen content of fuels such as biodiesel and alcohol can solve these combustion problems. The focus of this study is a detailed investigation of the effect on emissions of mixtures of DF, B100 derived from safflower seed oil with a low Free Fatty Acid (%FFAs) value, and n-decanol. Emission values obtained for DF, B100, 50%/50% volume ratio diesel/biodiesel (DF50B50), 50%/50% volume ratio diesel/n-decanol (DF50DE50), 50%/25%/25% volume ratio diesel/biodiesel/n-decanol (DF50B25DE25), Emission values of 50%/35%/15% diesel/biodiesel/n-decanol (DF50B35DE15) and 50%/45%/5% diesel/biodiesel/n-decanol (DF50B45DE5) blends were compared. Among these blends, compared to DF at maximum load, DF50B50, DF50DE50, DF50B25DE25, DF50B35DE15, and DF50B45DE5 fuels reduced smoke opacity (SO) by 80.17%, 86.78%, 54.55%, 21.49%, and increased it by 15.70%, respectively. Under the same load conditions, compared to DF, NOx emissions were reduced by 19.18%, 21.38%, 17.30%, increased by 34.91%, and reduced by 15.72% respectively with DF50B50, DF50DE50, DF50B25DE25, DF50B35DE15, and DF50B45DE5 fuels. Under the same load conditions, CO emissions were also reduced by 23.08%, 15.38%, 16.15%, increased by 40%, and reduced by 16.92% respectively with DF50B50, DF50DE50, DF50B25DE25, DF50B35DE15, and DF50B45DE5 fuels.

The new challenges posed at the European level, with the Next Generation EU, and at the national level, with the National Recovery and Resilience Plan, increase the priority of measuring spatial transformation through specific indicators. For this purpose, it is crucial to measure the effect of the transformations provided by current planning with respect to the goals of 2030 Agenda to assess their sustainability/unsustainability and, if necessary, propose improvements in the field of territorial planning. The work presented describes a research experience developed in collaboration with the Abruzzo Region, in Southern Italy, to support regional activities for the drafting of the Regional Sustainable Development Strategy (RSDS). The proposed methodology consists of a dynamic analysis through which it is possible to assess the positioning of regional planning in relation to the National Sustainable Development Strategy (NSDS) and the 17 Sustainable Development Goals (SDGs). Such position can be evaluated by carrying out a coherence analysis between the objectives of the Abruzzo Region's Plans and those of 2030 Agenda together with the selection of a set of indicators useful for monitoring the sustainability of territorial transformations expected by regional planning. In particular, the first recognition of the sustainability indicators was carried out from the ones proposed by the Italian National Institute of Statistics (ISTAT) and the Italian Institute for Environmental Protection and Research (ISPRA).
