Urbanization has resulted in a significant accumulation of waste densely populated areas. Effective household separation practices within urban areas are crucial for advancing the concept circular economy. The informal system contributed remarkably to material circulation, but it not been appropriately valued. Through partnership among municipal solid authorities, condominium building residents, and pickers, latter can be engaged community assist separation. This initiative would only enhance their income reduce probable occupational risks also augment recycling rate community. Based on insights from current picker assignment policy Taichung City, this study established mathematical programming model by considering overall volume proximal distance neighborhood, facilitating individual multiple communities neighborhood area. Consequently, concerned pickers may increase avoid constraints picking up recyclables high-occupational-risk Additionally, unsorted garbage According findings case studies, developed could obtain an optimal solution or acceptable approximate short timeframe. In contrast outcomes existing policy, application total sorted recyclables, which was directly proportional 2.3 2.6 times.
