Efficient and sustainable municipal solid-waste management is a social, environmental, and economic challenge. One practice that enhances the success of municipal solid-waste management is building and operating a household separation at source infrastructure for recycling. In this study, we use game-theory tools to identify difficulties that a municipality and its residents face in building and operating infrastructure for recycling under the Extended Producer Responsibility law. The model presents a holistic and broad perspective on the social and economic parameters that affect the efficiency of recycling in a municipality. We explain the strategies available to players and the factors affecting the utilities gained by waste separation and recycling. We present several Nash equilibria in pure and mixed strategies and specify the coordination game conditions. The model identifies parameters and their effect on the decision to recycle. The study presents changes needed to streamline a recycling system for an efficient equilibrium.
高效且可持续的城市固体废弃物管理是一项社会、环境和经济挑战。一种提高城市固体废弃物管理成功率的做法是建设并运营用于回收的源头家庭分类基础设施。在本研究中，我们运用博弈论工具来识别市政当局及其居民在《生产者延伸责任法》下建设和运营回收基础设施时所面临的困难。该模型从整体和广泛的角度阐述了影响城市回收效率的社会和经济参数。我们解释了参与者可用的策略以及影响通过废物分类和回收所获得效用的因素。我们给出了纯策略和混合策略中的几个纳什均衡，并明确了协调博弈条件。该模型识别了参数及其对回收决策的影响。本研究提出了为实现高效均衡而简化回收系统所需的变革。
