Abstract

In order to determine the effectiveness of turning frequency in maturity in kitchen waste composting process. Four treatments by setting up different turning frequency which are twice a week, once a week, once every two weeks and never turning were conducted during kitchen waste compositing with corn straw as compost amendment. Temperature, O2, GI, EC, pH were carried out as indexes. Results show that these treatments met the Chinese standard for 5-7days for sanitation except the treatment of never turned compost material. Only the treatment with turned material once a week up to the standard of maturity during co-composting completely; however, the treatment with turned compost material twice a week and never turned compost material are up to the standard of harmless only. Comprehensive above results, turn compost material once a week is the best turning frequency for kitchen waste composting.
