Municipal solid waste requires effective management to avoid adverse environmental impacts, such as pollution emissions and leachate discharge, and to enhance economic feasibility and societal acceptance. The current waste policy lacks the synergistic and integrated effect of the 3Ps dimensions – planet (environment), prosperity (economic), and people (social) – leading to unsustainable municipal solid waste management. This study develops a novel 3Ps nexus graphical portfolio that can be universally adoptable in various regions to quantitatively evaluate the life cycle sustainability of solid waste facilities relative to business-as-usual (i.e., open landfill). The 3Ps assessments, which share the backbone of life cycle analysis, are conducted to form the portfolio. Taking Malaysia as a case study, mechanical material recovery facility is the most sustainable solid waste facility, outperforming open landfill by 7.5 (environmental), 2.7 (economic), and 1.95 (social) times, followed by incineration, anaerobic digestion, tunnel composting, and sanitary landfill. Mechanical material recovery facility (−67.7 Pt) and incineration (−9.26 Pt) are the only solid waste treatment facilities with net environmental benefits due to the 298- and 4.18-times environmental saving effect, respectively, from their generated value-added by-product. Ten scenarios are further analysed, combining existing national municipal solid waste policies and zero-landfill targets. A scenario with 40% recycling is the most sustainable scenario for fulfilling the 3Ps. Recycling is recommended to be coupled with tunnel composting and anaerobic digestion to treat heterogeneous waste, rendering the scenario 1.04–33 times more sustainable than other integrated scenarios. To align with the 2030 Agenda, waste segregation is essential for sustainable waste management and can be supported by technology improvement, financial subsidy, and legislative enforcement.

城市固体废物需要有效管理，以避免污染排放和渗滤液排放等不利环境影响，并提高经济可行性和社会接受度。当前的废物政策缺乏3P维度——地球（环境）、繁荣（经济）和人民（社会）——的协同和综合效应，导致城市固体废物管理不可持续。本研究开发了一种新颖的 3P 关系图形组合，可在各个地区普遍采用，以定量评估固体废物设施相对于正常运营（即开放式垃圾填埋场）的生命周期可持续性。3P 评估共享生命周期分析的支柱，用于形成投资组合。以马来西亚为例，机械材料回收设施是最可持续的固体废物设施，其表现比露天垃圾填埋场高出7.5（环境）、2.7（经济）和1.95（社会）倍，其次是焚烧、厌氧消化、隧道堆肥、和卫生填埋场。机械材料回收设施（-67.7 Pt）和焚烧设施（-9.26 Pt）是唯一具有净环境效益的固体废物处理设施，因为其产生的附加值分别为298倍和4.18倍的环境节约效应。产品。结合现有的国家城市固体废物政策和零填埋目标，进一步分析了十种情景。40% 回收率的场景是实现 3P 的最可持续的场景。建议将回收与隧道堆肥和厌氧消化相结合来处理异质废物，使该场景的可持续性比其他综合场景高1.04-33倍。为了与 2030 年议程保持一致，废物分类对于可持续废物管理至关重要，并且可以得到以下支持：技术改进、财政补贴和立法执行。
