DEVELOPMENT OF EFFICIENT WINDROW COMPOSTING TECHNIQUE FOR FOOD WASTE AND ITS OPTIMIZATION

Abstract

Urban regions have a critical issue of solid management waste because of its high growing rate of production. Untreated solid waste had caused many diseases in human beings like cholera, yellow fever and dengue fever. Windrow composting for food waste including bio-degradable and recyclable nature were checked for different compositions of food waste. Food waste composting by aerobically was carried out at South East Asian institute of Sciences, UAF. Three different windrows were reinforced with treatments of tap water, sewage water and microbial spray. Aerobic composting required different temperature tolerating microbes to complete the composting process. The analysis have been done in laboratory for many compost effecting parameters. Results showed that organic content analysis have better for composting of food waste. Three composting windrows were developed with three different treatments T1, T2 and T3 for food waste. Windrows were treated with sewerage water, tap water and effective microbial spray using specifically food waste. The compost of food waste prepared by the treatment of microbial spray was found better than the two treatments as having pH 8.63, organic content 68.91%, moisture content 28.09%, carbon 32.38%, nitrogen 0.67%, Phosphorous 1.3% and potassium 0.81%. Physical and chemical characteristics of compost has been analyzed, presented and transformed in graphs to check the relevance in all the composting parameters throughout the three composting piles of waste like M.C, Temperature, pH, O.C, C, N, P, K.
