本研究は、インドネシアの一般廃棄物(MSW)から製造された廃棄物燃料(RDF)の火力発電所での混焼に関するライフサイクルアセスメント(LCA)を実施。粗粉砕と発電所への輸送が主な温暖化ホットスポットで、RDF 1トン当たり7.49kg CO2eqのGWPを算出。一方、回避排出量は年間MSW 1トン当たり773.56kg CO2eqと推定され、99.9%の削減率を示した。RDFの再生可能エネルギー源と廃棄物管理の二重の利点を実証。
English
This study conducts a life cycle assessment (LCA) of refuse-derived fuel (RDF) from municipal solid waste for co-firing in coal power plants in Indonesia. The global warming potential (GWP) is 7.49 kg CO2 eq per ton of RDF, with coarse grinding and transport as hotspots. Avoided emissions reach 773.56 kg CO2 eq per ton of MSW per year, a 99.9% reduction. Results highlight RDF's dual role as renewable energy and waste management solution.

日本のGX文脈において
インドネシアは廃棄物発電と混焼政策を推進中。本研究はRDFの環境性能を定量評価し、日本の廃棄物発電やバイオマス混焼政策への示唆も含む。日本では一般廃棄物発電が普及しているが、RDFのLCAデータは限られており、本研究成果は比較対象として有用。
In the global GX context
Indonesia's increasing waste and coal dependence make RDF co-firing a promising transition strategy. This LCA provides rigorous GWP and avoided emission data, relevant for global waste-to-energy and co-firing policy. While Indonesia-specific, the methodology applies to other developing countries facing similar waste and energy challenges.

📄 Abstract（原文）
Abstract The increasing generation of municipal solid waste (MSW) in Indonesia poses significant environmental challenges, including the accumulation of organic waste in landfills that contributes to greenhouse gas emissions, while simultaneously offering opportunities for renewable energy production. Converting MSW into refuse‐derived fuel (RDF) for co‐firing in coal‐fired power plants provides a dual benefit by reducing waste accumulation and supplying a low‐carbon energy source. This study evaluates the environmental performance of RDF using a life cycle assessment (LCA) approach, with a functional unit of one ton of RDF and a cradle‐to‐gate system boundary encompassing all processes from waste collection to delivery at the power plant gate. Global warming potential (GWP) was assessed using the Centrum voor Milieukunde – Impact Assessment (CML‐IA) baseline method. Primary data were collected directly from waste handling and RDF production activities in Banten, Indonesia. Secondary data, it obtained from scientific literature and the Ecoinvent 3.8 with allocation at the point of substitution system model. The life cycle impact assessment GWP of RDF was determined to be 7.49 kg CO 2 eq per ton, with coarse grinding identified as the primary hotspot, contributing 2.72 kg CO 2 eq, followed by transportation to the power plant at 2.10 kg CO 2 eq. Potential avoided emissions were quantified at 773.56 kg CO 2 eq per ton of MSW per year, representing a reduction of approximately 99.9%. These results highlight RDF's dual role as a renewable energy source and an effective waste‐management, demonstrating its substantial climate mitigation potential and supporting sustainable energy policies in Indonesia.
