In recent years, considerable studies have been devoted to investigating the effect of biochar application on organic solid waste composting. This review provides an up-to-date overview of biochar amendment on composting processes and compost quality. Biochar production, characteristics, and its application coupled with the basic concepts of composting are briefly introduced before detailing the effects of biochar addition on composting. According to recent studies, biochar has exhibited great potential for enhancing composting. It is evident that biochar addition in composting can: (1) improve compost mixture physicochemical properties, (2) enhance microbial activities and promote organic matter decomposition, (3) reduce ammonia (NH) and greenhouse gas (GHG) emissions, and (4) upgrade compost quality by increasing the total/available nutrient content, enhancing maturity, and decreasing phytotoxicity. Despite that, further research is needed to explore the mechanism of biochar addition on composting and to evaluate the agricultural and environmental performances of co-composted biochar compost.
近年来，人们投入了相当多的研究来调查生物炭应用对有机固体废物堆肥的影响。本综述提供了生物炭改良对堆肥过程和堆肥质量的最新概述。在详细介绍生物炭添加对堆肥的影响之前，简要介绍了生物炭的生产、特性及其与堆肥基本概念的结合。根据最近的研究，生物炭在堆肥中显示出了很大的潜力。显然，生物炭在堆肥中的添加可以：（1）改善堆肥混合物的物理化学性质，（2）增强微生物活性并促进有机物分解，（3）减少氨（NH）和温室气体（GHG）排放，以及（4）通过增加总/有效养分含量、提高成熟度和降低植物毒性来提高堆肥质量。尽管如此，仍需要进一步研究来探索生物炭添加对堆肥的作用机制，并评估共堆肥生物炭堆肥的农业和环境性能。
