Abstract

Based on large quantity and low resource utilization of edible fungi residue in Beijing, the life cycle assessment of edible fungi residue compost was carried out. The environmental impacts including global warming (GW), acidification (AC), eutrophication (EU) and photochemical ozone (PO) were evaluated. Results indicated that edible fungi residue compost was the major risk to acidification and eutrophication. On the contrary, global warming and photochemical ozone were at a low level of potential environmental impact. The potential environment impact of four impact classes and the sum of them 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, all lower than China’s per capita impact potential. The data indicated that developing edible fungi residue compost to replace part of using of the landfill and random stacking treatment could effectively reduce environment potential impact. Applied to edible fungi residue compost, life cycle assessment could quantify the effect of different environment impact classes, which provide a scientific basis for selecting recycle technology and management plan.
