Abstract

Highlights: Bulking wastes enhance the enzymatic activity and rate of composting. Addition of WSW as bulking waste significantly improved compost quality. Inoculation of microbial consortium with bulking agent reduces the composting period. All three microbial strains are compatible and form a stable consortium. Abstract: The effect of various bulking waste such as wood shaving, agricultural and yard trimming waste combined with organic fraction of municipal solid waste (OFMSW) composting was investigated through assessing their influence on microbial enzymatic activities and quality of finished compost. All three piles of OFMSW with different bulking waste were inoculated with microbial consortium. The results revealed that OFMSW combined with wood shaving and microbial consortium ( Phanerochaete chrysosporium, Trichoderma viride and Pseudomonas aeruginosa ) were helpful tool to facilitate the enzymatic activity and shortened composting period within 4 weeks. Maximum enzymatic activity were observed in pile 1 and 3 during the first 3 weeks, while in pile 2 relatively very low. But phosphatase activity was relatively higher in all piles until the end of the process. Maturity parameters of compost quality also favored the pile 1 as the best formulation for OFMSW composting.
