Environmental Life Cycle Assessments of Chicken Manure Compost Using Tobacco Residue, Mushroom Bran, and Biochar as Additives

As an environmental management method, the (life cycle assessment) LCA method can be used to compare differences between various waste treatment processes in order provide environmentally friendly and economically feasible for management. This study focused on reutilization of typical organic produce fertilizer southwest China life assessment evaluate three aerobic chicken manure composting scenarios modified with additives (biochar, mushroom bran, tobacco residue) from economic perspective. The results show that total loads optimized treatments using bran biochar mixed as were reduced by 30.0% 35.1%, respectively, compared control (viz. composted residue). Compared treatment, without improved profit 23.9% 35.4%, respectively. work reflected combined mode manure, residue, is process, which more suitable resource utilization China.
