建立可持续的土壤废物管理做法意味着尽量减少与气候变化(温室气体：温室气体)和生态系统酸化(氨：NH3)有关的环境损失。虽然已对固体废物管理的若干管理战略进行了调查，以量化与不同环境和作业条件有关的氮(N)和碳(C)损失，但其总体效果仍不确定。在此背景下，我们通过系统的回顾对当前的科学信息进行了分析。我们量化了温室气体排放、NH3排放和总氮损失对不同固体废物管理策略(传统固体储存、翻转堆肥、强制通风堆肥、覆盖、压实、添加/替代膨胀剂和使用添加剂)的响应。我们的研究是基于对涉及304个观察的50篇研究文章的荟萃分析。我们的结果表明，通过添加或替代某些膨胀剂来改善堆体(垃圾或粪便堆)的结构，可以显著减少一氧化二氮(N2O)和甲烷(CH4)的排放，分别减少53%和71%。与强制通风堆肥系统不同，翻转堆肥系统显示出减少温室气体(N2O：50%和CH4：71%)的潜力。膨胀剂和两种堆肥系统都涉及到一定程度的污染交换，因为它们显著增加了膨胀剂、翻堆和强制通风堆肥的NH3排放量35%、54%和121%。基于氧气供应限制的覆盖或压实等措施对温室气体的减排效果不显著，但覆盖和压实的NH3排放量分别显著减少了61%和54%。特定添加剂的使用显著减少了69%的NH3损失。我们的荟萃分析表明，有足够的证据可以从固体废物中提炼未来的政府间气候变化专门委员会(IPCC)方法，特别是固体废物堆肥实践。因此，需要采取更全面和更综合的办法来制定更可持续的固体废物管理系统。
The establishment of sustainable soil waste management practices implies minimizing their environmental losses associated with climate change (greenhouse gases: GHGs) and ecosystems acidification (ammonia: NH3). Although a number of management strategies for solid waste management have been investigated to quantify nitrogen (N) and carbon (C) losses in relation to varied environmental and operational conditions, their overall effect is still uncertain. In this context, we have analyzed the current scientific information through a systematic review. We quantified the response of GHG emissions, NH3 emissions, and total N losses to different solid waste management strategies (conventional solid storage, turned composting, forced aerated composting, covering, compaction, addition/substitution of bulking agents and the use of additives). Our study is based on a meta-analysis of 50 research articles involving 304 observations. Our results indicated that improving the structure of the pile (waste or manure heap) via addition or substitution of certain bulking agents significantly reduced nitrous oxide (N2O) and methane (CH4) emissions by 53% and 71%, respectively. Turned composting systems, unlike forced aerated composted systems, showed potential for reducing GHGs (N2O: 50% and CH4: 71%). Bulking agents and both composting systems involved a certain degree of pollution swapping as they significantly promoted NH3 emissions by 35%, 54%, and 121% for bulking agents, turned and forced aerated composting, respectively. Strategies based on the restriction of O2 supply, such as covering or compaction, did not show significant effects on reducing GHGs but substantially decreased NH3 emissions by 61% and 54% for covering and compaction, respectively. The use of specific additives significantly reduced NH3 losses by 69%. Our meta-analysis suggested that there is enough evidence to refine future Intergovernmental Panel on Climate Change (IPCC) methodologies from solid waste, especially for solid waste composting practices. More holistic and integrated approaches are therefore required to develop more sustainable solid waste management systems.
