social life cycle assessment of biofuel production 2019
... However, it is important to consider the potential feedback effects and unintended consequences of implementing reformulated diesel marketing strategies, which may impose additional costs on society. Therefore, policymakers and the public should be mindful of the economic, social, and environmental implications of any developed fuel policy [65]. In this context, it is important to explore the sustainability of higher alcohol production. ...
... He also proposed the LCSA plan, which posits that society relies on the economy, and the economy depends on the global environment. LCSA is a valuable tool for supporting product development, including eco-design features that reduce the negative life cycle impacts on the environment, society, and economy [65] Fig. 9.2 illustrates the fundamental components and issues involved in evaluating the sustainability of various systems. Using LCSA to evaluate the sustainability of higher alcohol production as a fuel additive, policymakers can ensure that their decisions are guided by a comprehensive understanding of their choices' environmental, economic, and social implications. ...
One of the most current discussions in the transportation sector is air pollution caused by diesel engines. In fact, even with the advances in engine technologies, the combustion of diesel in internal combustion engines leads to the significant release of toxic gases into the atmosphere, such as particulate matter and nitrogen oxide, posing threats to human health and the environment. Although researchers proposed replacing petroleum-based diesel with bio-based diesel, technical, environmental, and economic challenges make their sustainability questionable. In line with that, more sustainable techniques have been introduced to reduce the toxic gas emissions from diesel combustion. Modifying diesel properties using fuel additives or reformulation is a straightforward and economical alternative among these techniques. Various additives, such as oxygenated, cetane number improvers, metal-based compounds, antioxidants, lubricity improvers, and cold flow improvers, are commercially used to improve diesel properties. Among these, higher alcohols as oxygenated additives due to their higher oxygen content and latent heat than diesel can shift the combustion process toward lower temperatures, lowering particulate matter and nitrogen oxide emissions. Despite the promising results offered by higher alcohols as fuel additives for diesel, the sustainability of their production from an environmental, economic, and social point of view should not be neglected. In better words, the decision-making process should not focus on the effects of higher alcohols on exhaust pollutants only, but also it should consider the principles of sustainable development in the background process of higher alcohols, that is, a cradle-to-grave approach. Life cycle sustainability assessment is a valuable tool to address this problem through systematical evaluation of environmental, economic, and social background processes or production of higher alcohols. This chapter aims to better understand the environmental, economic, and social aspects of higher alcohol production based on a life cycle sustainability assessment approach.
... S-LCA and S-CBA can help the organization deliver its missioncritical services, engage its communities, and increase trust among stakeholders. S-LCA is a method that assesses the social and socioeconomic impacts of a product throughout its life cycle, from raw material extraction to disposal (Mattioda et al., 2020). On the other hand, S-CBA is a method that compares the social costs and benefits of a project or policy, taking into account the externalities that are not reflected in the market price (Zhang et al., 2021). ...
This work presents a comprehensive Social Life Cycle Assessment (S-LCA) and Social Cost-Benefit Analysis (S-CBA) conducted as part of a research project, studying biofuel production for the maritime and aviation sectors, from various types of non-food waste biomasses. The inclusion of social considerations complements and expands on the environmental and economic ones. The importance of social group criteria was determined through expert questionnaires, leading to the identification of social impacts groups and social criteria from stakeholders across participating countries. The results successfully identified and quantified social impacts, and align with those reported in similar cases in relevant literature. Social Cost-Benefits, monetarizing social factors, demonstrated several social benefits, including reduction in Greenhouse Gas Emissions. However, it also highlighted social costs, such as Economic Costs associated with the initial investment. The study revealed critical social hotspots within the impact categories, making significant strides in understanding the social impacts of biofuel production, providing valuable insights for decision-makers, and contributing to the broader goal of sustainable and socially responsible biofuel production.
... the biofuel yielded could not compete effectively with non-renewable fuels in the market. Yet, the techno- Mattioda et al. (2020), state that the integration of sustainability into biorefinery project design faces 83 challenges such as a comprehensive analysis that considers social impacts, limited data availability, 84 disciplinary limitations, and the subjectivity of sustainability. 85 ...
... Despite being a rather neglected area within the literature related to bio-based products in general, the social dimension has gained importance over the last years, and the S-LCA method has been increasingly employed (Falcone and Imbert, 2018;Imbert and Falcone, 2020). Several S-LCA studies related to bioenergy have been indeed published so far (e.g., Ekener et al., 2018;Manik et al., 2013;Mattioda et al., 2020;Petersen et al., 2014). Although employing different system boundaries, as for instance some of them did not consider the consumption phase, several main socio-economic issues have emerged, encompassing, among others, short-and long-term effects on human health, labor and gender issues, property rights, access to land, food security, wealth and well-being creation. ...
The bioenergy sector is becoming of increasing interest: the European Union is not an exception. Indeed, it is in need of solutions to face one of the worst energy crises of the last century. The sector’s growth faces numerous challenges. The main use of energy crops, as feedstock, generates stiff competition on the use of land for food and energy purposes. The production of bioenergy has relevant environmental implications in terms of greenhouse gas emissions. The social aspects related to the bioenergy sector are also poten- tial obstacles to its development. These pressing issues for policymakers call for a better understanding on how national and international laws should regulate the growth of the bioenergy sector. Flying over the economic, environmental, social, and legislative aspects faced by the bioenergy sec- tor, we conclude on threads, opportunities, and priorities that should be considered for its development and propose directions for future studies.
Os sistemas ou cadeias produtivos apresentam desafios quanto ao que se refere à sustentabilidade nas organizações, diante das dinâmicas em torno da mitigação e adaptação às mudanças climáticas, do alcance dos Objetivos de Desenvolvimento Sustentável (ODS) da Organização das Nações Unidas (ONU) e, mais recentemente, em função da pande- mia de covid-19. Isso evidencia que as empresas não são apenas meros atores econômicos, mas desempenham papéis com interfaces ecosso- cioeconômicas, o que sugere que as cadeias produtivas sustentáveis são novos processos de governança.
Assessing the prospective climate preservation potential of novel, innovative, but immature chemical production techniques is limited by the high number of process synthesis options and the lack of reliable, high-throughput quantitative sustainability pre-screening methods. This study presents the sequential use of data-driven hybrid prediction (ANN-RSM-DOM) to streamline waste-to-dimethyl ether (DME) upcycling using a set of sustainability criteria. Artificial neural networks (ANNs) are developed to generate in silico waste valorization experimental results and ex-ante model the operating space of biorefineries applying the organic fraction of municipal solid waste (OFMSW) and sewage sludge (SS). Aspen Plus process flowsheeting and ANN simulations are postprocessed using the response surface methodology (RSM) and desirability optimization method (DOM) to improve the in-depth mechanistic understanding of environmental systems and identify the most benign configurations. The hybrid prediction highlights the importance of targeted waste selection based on elemental composition and the need to design waste-specific DME synthesis to improve techno-economic and environmental performances. The developed framework reveals plant configurations with concurrent climate benefits (-1.241 and -2.128 kg CO2-eq (kg DME)-1) and low DME production costs (0.382 and 0.492 € (kg DME)-1) using OFMSW and SS feedstocks. Overall, the multi-scale explorative hybrid prediction facilitates early stage process synthesis, assists in the design of block units with nonlinear characteristics, resolves the simultaneous analysis of qualitative and quantitative variables, and enables the high-throughput sustainability screening of low technological readiness level processes.
