主　　题：Composting 

摘      要：There is high solid waste generation rate and about 90% is land filled and only 5% is composted in Ethiopia. Therefore, we carried out study on municipal solid wastes composting using Trichoderma harzianum inoculants and use as biofertilizer. From physicochemical analysis of matured compost the results were within the range of acceptable limits set by most countries guidelines for agricultural inputs. Furthermore, matured compost showed the mean number of bacterial colonies ranges from 9.18 × 106 to 1.86 × 107 cfu g-1 and whereas fungal colonies ranges from 1.27 × 104 to 1.59 × 104 cfu g-1. Composting facilitated the recovery of biodegradable organic wastes by converting into organic fertilizers and minimized the overflow of municipal solid waste dumped to landfills. In present study using Trichoderma harzianum inoculants did not further improve compost physicochemical properties as compared to the control treatments with only natural microbial decomposers. Therefore, inoculants of Trichoderma harzianum to facilitate composting and the recovery of biodegradable organic wastes needs further study for others parameters optimization. © 2019 Widener University School of Civil Engineering.
