Abstract

Purpose of Review

Home composting is an effective way to treat household waste, but global uptake remains low because of insufficient recognition and technical limits. This review aims to promote the understanding, popularization, and application of home composting by summarizing the facilities, process performance, and product quality, and to sum up the crucial technical limits and potential solve methods.

Recent Findings

Home composting studies are carried out in 20–1200 L composters for 3–12 months with kitchen and garden feedstocks. During the process, emission amounts of methane (CH₄), nitrous oxide (N₂O), and ammonia (NH₃) are 0.002–2185 kg/Mg FW, 0.004–454 kg/Mg FW, and 0.025–972 kg/Mg FW, respectively. The thermophilic stage in home composting is insufficient for harmless requirement, while the home composting products could meet the standards for the use of organic fertilizer when the basic physical and chemical indicators, biological indicators, spectral indicators, and other indices are carried out in lab. Home composting products are non-toxic to plants and can promote plant growth. The crucial technical limits are caused by slow degradation of organic matter (OM), emission of greenhouse gases (GHGs) and a lack of maturity evaluation standard and directive for subsequent product utilization.

Summary

Suitable technology and evaluation standard could reduce gas emissions and improve maturity of home composting, which would provide an additional method for existing municipal waste management, therefore reducing the transportation and collection cost of household waste, and realizing the reduction, harmless, and resource recovery.

家庭堆肥法现场处理生活有机固体废物的研究进展

家庭堆肥是一种有效的处理生活垃圾的方法，但由于认识不足和技术限制，全球吸收量仍然很低。本文旨在通过对家庭堆肥的设施、工艺性能、产品质量等方面的综述，促进人们对家庭堆肥的认识、推广和应用，并总结其中的关键技术限制和可能的解决方法。最近的发现家庭堆肥研究进行了20-1200升堆肥与厨房和花园的原料3-12个月。在此过程中，甲烷(CH4)、氧化亚氮(N2O)和氨(NH3)的排放量分别为0.002 ~ 2185 kg/Mg FW、0.004 ~ 454 kg/Mg FW和0.025 ~ 972 kg/Mg FW。家庭堆肥的亲热阶段不足以满足无害化要求，而家庭堆肥产品在实验室进行基本理化指标、生物指标、光谱指标等指标时，可以满足有机肥的使用标准。家庭堆肥产品对植物无毒，能促进植物生长。关键的技术限制是由于有机物(OM)降解缓慢、温室气体(GHGs)排放和缺乏成熟度评价标准和后续产品利用指令。合适的技术和评价标准可以减少气体排放，提高家庭堆肥的成熟度，为现有的城市垃圾管理提供一种新的方法，从而降低生活垃圾的运输和收集成本，实现减量化、无害化和资源化。
