Abstract

Batang Regency encountered persistent waste management challenges, requiring effective mitigation strategies. This study evaluated residential waste management utilizing life cycle assessment (LCA) and material flow analysis (MFA) to propose sustainable plans. Three scenarios were compared: the current conditions (Scenario 1) had the highest environmental impact. In contrast, Scenarios 2 and 3, which included sorting and recycling processes, demonstrated improved energy and product recovery, making them more sustainable. The results indicated that Scenario 1 had a global warming potential (GWP) of up to 1.65E+04 CO₂ eq/t MSW, Scenario 2 had up to 2.88E+03 CO₂ eq/t MSW, and Scenario 3 had up to 3.08E+03 03 CO₂ eq/t MSW. Scenario 2 exhibited a lower GWP than Scenario 1, while Scenario 3, although higher in GWP, was recommended for excluding landfills. These findings highlighted the potential for waste sorting improvements and adjustments to classified waste treatment with environmental regulations, supporting sustainability in Batang Regency's waste management.

加强巴塘县的废物管理：将循环经济原则与生命周期评估和物料流分析相结合

巴塘县（Batang Regency）面临着持续的废物管理挑战，需要有效的缓解策略。本研究利用生命周期评估（LCA）和物质流分析（MFA）对住宅废物管理进行了评估，以提出可持续发展计划。对三种方案进行了比较：当前状况（方案 1）对环境的影响最大。相比之下，方案 2 和方案 3（包括分类和回收流程）在能源和产品回收方面有所改善，更具可持续性。结果表明，方案 1 的全球升温潜能值（GWP）高达 1.65E+04 CO2 当量/吨 MSW，方案 2 高达 2.88E+03 CO2 当量/吨 MSW，方案 3 高达 3.08E+03 03 CO2 当量/吨 MSW。方案 2 的全球升温潜能值低于方案 1，而方案 3 虽然全球升温潜能值较高，但建议将其排除在垃圾填埋场之外。这些发现凸显了改进废物分类和调整废物分类处理以符合环境法规的潜力，从而支持巴塘县废物管理的可持续性。
