摘要：Based on large quantity and low resource utilization of edible fungi residue in Beijing, the life cycleassessment of edible fungi residue compost was carried out. The environmental impacts includingglobal warming (GW), acidification (AC), eutrophication (EU) and photochemical ozone (PO) wereevaluated. Results indicated that edible fungi residue compost was the major risk to acidification andeutrophication. On the contrary, global warming and photochemical ozone were at a low level ofpotential environmental impact. The potential environment impact of four impact classes and the sum ofthem were 3.58×10 -7 PE, 1.93×10 -5 PE, 1.75×10 -5 PE, 3.40×10 -6 PE and 4.06×10 -5 PE respectively, alllower than China’s per capita impact potential. The data indicated that developing edible fungi residuecompost to replace part of using of the landfill and random stacking treatment could effectively reduceenvironment potential impact. Applied to edible fungi residue compost, life cycle assessment couldquantify the effect of different environment impact classes, which provide a scientific basis forselecting recycle technology and management plan.
