Carbon reduction of plastic’s circular strategies: tracking the effects along supply chains with waste input–output modeling

Abstract Plastic is a material associated with various Greenhouse Gas (GHG) emissions along the life cycles of different products. Many economies have adopted or planned for strategies to reduce, reuse, and recycle plastic goods materials. The benefits reductions in waste generation GHG need be evaluated setting priority select policy instruments managing materials, products, wastes. Several studies made evaluations circulation using models. However, many models circular economy focused on effect macroeconomy rather than detailed supply chain effects an individual proposal. reason could lack environmental assessment model sufficient clear resolutions sectors, types, treatments. In addition, structure limits modeling scenarios diverting end-of-life products from treatments recycling reuse as secondary To bridge this gap, study input–output analysis methodology compiled baseline four flow stream data Taiwan reference classification kinds intervention review paper. We provide details about results settings solid recovered fuel power generation, closing loops bags, extending cabinets other improving chain’s resource efficiencies. illustration chains treatment activities, we present Sankey diagrams, which make more straightforward. developed method render diagram result input–output-based presented article.
