Abstract:
The increasing problems of population explosion and rapid urbanization has led to generation of huge amounts of waste, disposal of which is a major concern worldwide. Composting, a viable alternative for efficient disposal of the waste not only mitigates the environmental pollution problems but also benefits biomass production. However to get compost in short time it is important that the composting process should be accelerated. Efficient microorganisms play vital role in producing quality compost efficiently and thereby reducing the duration. The present study focuses on production of compost using kitchen waste through rapid composting employing efficient microorganisms, viz., Paecilomyces variottii (PV), Lactobacillus (LB) and Azotobacter chroococcum (AC), Pseudomonas fluorescens (PF). Studies at the field level showed positive interaction among the selected microbes. These microbes were further evaluated for rapid composting of waste (kitchen waste and cow dung in ratios (3:1). Four treatments, i.e., AC+LB, PV+LB, PF+LB, AC+PV+PF+LB, along with an uninoculated control were maintained. Experiment was preformed for a period of 60 days, during the course of which samples were periodically collected every 10 days and analyzed for various parameters, viz., microbial count, EC, pH, nutrients (C, N, P, K) celluloses, hemicelluloses and lignin. It was observed that all microbes showed good growth till 30 days of composting after which the growth started to cease with time. Lactobacillus, on the other hand, was completely absent in the last phase (50-60 days) of the composting. An increase in EC along with a shift from acidic to basic pH was recorded in the compost samples. The complex molecules (celluloses, hemicelluloses and lignin) and carbon content showed a significant decrease along with an increase in the nutritive content (N, P, K) of the compost. The study thus proved beneficial for effective management of kitchen waste by employing efficient micro-organisms along with production of nutrient rich biomass (manure).
