本レビューは、都市固形廃棄物（MSW）管理における好気性堆肥化を、嫌気性消化（AD）と比較して、より優れたCCUS経路として位置づける。好気性堆肥化はメタン排出を抑制し、有機炭素を腐植化土壌有機物として安定化させることで、長期的な炭素隔離を実現する。また、土壌改良や作物生産性向上などの農業的便益ももたらす。ADはバイオエネルギー回収が可能だが、メタン漏洩や消化物管理の不確実性がある。一方、好気性堆肥化はMRVの透明性が高く、炭素市場への統合に有利で、低コストで分散型展開が可能。Novcom技術などの革新により、21日での高速処理、病原体不活化、重金属の80%低減、99%のメタン削減が達成できる。

This review positions aerobic composting of municipal solid waste (MSW) as a superior CCUS pathway compared to anaerobic digestion (AD). Aerobic composting suppresses methane emissions and stabilizes organic carbon into humified soil organic matter, enabling durable carbon sequestration while improving soil properties and crop productivity. AD offers bioenergy recovery but faces uncertainties from fugitive methane and digestate management. Aerobic composting provides transparent MRV, additionality, and permanence for carbon markets, with low infrastructure needs enabling decentralized deployment. Innovations like Novcom achieve rapid bioconversion (~21 days), pathogen inactivation, 80% heavy metal reduction, and up to 99% methane mitigation.

📄 Abstract（原文）

Rapid urbanisation and the concomitant surge in municipal solid waste (MSW) generation are intensifying environmental and public health risks globally, notably through greenhouse gas (GHG) emissions and the loss of recoverable nutrients. Framed within an urban carbon–nutrient cycle perspective, this review critically positions aerobic composting as a scalable, low-risk carbon capture, utilisation, and storage (CCUS) pathway for MSW management, in contrast to forced methanogenesis via anaerobic digestion (AD). Synthesised evidence demonstrates that optimised aerobic composting systems effectively suppress methane emissions while facilitating the transformation and stabilisation of organic carbon into humified soil organic matter, thereby enabling durable carbon sequestration. Concurrently, compost application improves soil physicochemical properties, enhances water-holding capacity, and supports sustained crop productivity, linking waste management with climate-resilient agroecosystem functioning. Although AD enables bioenergy recovery, its net climate benefits remain conditional upon stringent control of fugitive methane emissions, efficient digestate management, and sustained operational stability—factors that often introduce uncertainty under field-scale conditions. In contrast, aerobic composting offers a more direct and comparatively lower-risk methane mitigation pathway, alongside distinct advantages for carbon market integration, including greater transparency in monitoring, reporting, and verification (MRV), and clearer demonstration of additionality and permanence. Its relatively low technological and infrastructural requirements further enable decentralised deployment, particularly in resource-constrained settings. Notably, emerging innovations such as Novcom technology underscore the transformative potential of advanced composting systems by enabling rapid MSW bioconversion (≈21 days), effective pathogen inactivation, and substantial reduction in heavy metal bioavailability (up to 80%) via organo-complexation. Critically, such systems achieve near-complete methane mitigation (up to 99%), reinforcing their climate mitigation efficacy without necessitating extensive infrastructure. Collectively, aerobic composting represents a robust and integrative solution for sustainable MSW management, delivering synergistic environmental, agronomic, and socio-economic co-benefits. This review advocates for its prioritisation within municipal policy frameworks and operational strategies, alongside targeted research on feedstock optimisation, process intensification, and long-term soil carbon dynamics to fully realise its CCUS potential.
