Developing circularity, renewability and efficiency indicators for sustainable resource management: Propanol production as a showcase

چکیده
Resource efficiency analysis is an important tool in the chemical sector to evaluate performance of new process concepts. However, such does not account for renewability and circularity resources. Therefore, a resource use analysis, including those two aspects, proposed this paper. A indicator recovery were calculated as measure circularity, respectively. In addition, was determined at different levels. At life cycle level, cumulative exergy extraction natural environment method applied degree perfection, waste-as-resources, calculated. Exergy calculations used determine exergetic chain plant level identify inefficiencies. propanol production concept, using biogas (scenario BG), marginal gas MG) associated AG), selected case study. Exergetic efficiencies are high individual (between 90 100%). preceding scenario BG inefficient (exergetic 12%). The amounts 45–68% due content recycling stream low conversion methane into per pass. Scenario AG has highest perfection (including waste-as-resources) compared other scenarios (28% against 6 14% MG). contrast, when looking both renewability, efficiency, identified most promising scenario. Thus, study shows that it include three aspects analysis. Finally, implementing renewable electricity heat integration concept may increase efficiency. • (REU) proposed. Circularity integrated Propanol from unconventional sources efficient starting gas. seems interesting based on REU

Early researchers identified key concepts and developed tactics for multiple-option management of nematodes. Although the emphasis on integrated pest management over the past three decades has promoted strategies and tactics for nematode management, comprehensive studies on the related soil biology-ecology are relatively recent. Traditional management tactics include host resistance (where avai...
