Except for PC, all other methods of composting satisfied all the indices for stability/maturity of compost at the 60th day of sampling whereas PC achieved the critical limit values for most of the indices at the 80th day. The evolution of total nitrogen and germination index also varied significantly (P ≤ 0.001) with time, but their variation among the composting methods was not significant (P > 0.05). The evolution of composting temperature, pH, EC, \(\) ratio, OC, C:N ratio and total volatile solids varied significantly among the composting methods and with composting time. The analysis of variance was performed using SAS software and the significant differences were determined using Fisher’s LSD test at P ≤ 0.05 level. The changes in physico-chemical and biological characteristics of the compost were examined at 20 days interval for 100 days using standard laboratory procedures. The composting treatments were arranged in a completely randomized block design with three replications. windrow composting (WC), Vermicomposting (VC), pit composting (PC) and combined windrow and vermicomposting (WVC) on the stabilization, maturation and sanitization of mixtures of municipal solid organic waste and dried faecal sludge. ![]() This study was aimed to investigate the comparative effectiveness of four different methods of composting viz. ![]() Composting methods vary in duration of decomposition and potency of stability, maturity and sanitation. Composting is one of the integrated waste management strategies used for the recycling of organic wastes into a useful product.
