Journal ArticleDOI
Improving pig manure composting efficiency employing Ca-bentonite
Quan Wang,Ronghua Li,Hanzhen Cai,Mukesh Kumar Awasthi,Mukesh Kumar Awasthi,Zengqiang Zhang,Jim J. Wang,Amjad Ali,Mahar Amanullah +8 more
TL;DR: In this article, the effect of added Ca-bentonite (CB) on nutrient transformation during pig manure (PM) composting and the related effects on Cu and Zn accumulation in crops were investigated.
Journal ArticleDOI
Comparative evaluation of the use of acidic additives on sewage sludge composting quality improvement, nitrogen conservation, and greenhouse gas reduction
Junting Pan,Hanzhen Cai,Zengqiang Zhang,Hongbin Liu,Ronghua Li,Hui Mao,Mukesh Kumar Awasthi,Quan Wang,Limei Zhai +8 more
TL;DR: According to comprehensive evolution of N loss, GHG emissions and compost maturity in this study, the feasibility of using AP, CA, and PM in high-quality compost production is promising and could improve the N conservation.
Journal ArticleDOI
In-vessel co-composting of biosolid: Focusing on mitigation of greenhouse gases emissions and nutrients conservation
Mukesh Kumar Awasthi,Mukesh Kumar Awasthi,Quan Wang,Hongyu Chen,Meijing Wang,Sanjeev Kumar Awasthi,Xiuna Ren,Hanzhen Cai,Ronghua Li,Zengqiang Zhang +9 more
TL;DR: In this article, the feasibility of Calcium-bentonite (Ca-B) combined with biochar (B) as an effective amendment for the cocomposting of dewatered fresh sewage sludge (DFSS) mixed with wheat straw (WS), focusing on mitigation of greenhouse gases (GHG) emission and nutrients loss.
Journal ArticleDOI
Sulfur-aided composting facilitates ammonia release mitigation, endocrine disrupting chemicals degradation and biosolids stabilization.
Ronghua Li,Kaili Xu,Amjad Ali,Hongxia Deng,Hanzhen Cai,Quan Wang,Junting Pan,Chein Chi Chang,Hongbin Liu,Zengqiang Zhang +9 more
TL;DR: Results implicated addition of S decreased alkalinity of compost system, mitigated NH3 volatilization, facilitated degradation of bisphenol A and estrogen in biosolids, and improved biosolid stabilization.
[Effects of Bentonite Amendment on Detoxification, Heavy Metal Passivation and Estrone Elimination of Sewage Sludge Compost].
TL;DR: The study indicated that bentonite addition of lower than 5% was acceptable for the sludge compost amendment, which had great potential in sludge hygienization, detoxification, heavy metal passivation and E1 elimination.
