INNOVATIVE COMPOSTING PROCESS FOR ENHANCING ORGANIC WASTE MANAGEMENT IN URBAN AREAS

Abstract

Towns and cities produce large quantities of organic waste which is problematic for waste management structures. This work assesses contingency of new approaches to composting in the fight against the management of organic waste in urban areas. The research focuses on three key composting methods which include aerobic composting, anaerobic digestion and vermicomposting. Samples were obtained from the urban communities that practiced these measures for one year. It was revealed that aerobic composting if implemented lowers the quantity of organic waste through composting to sixty-five percent and attains the compost maturity index of 0.85 and simultane ously producing 40% less total greenhouse gasses compared to those produced when landfilling. Biogas from the anaerobic digestion with a methane content of 60% offers 1.2 kWh of energy per kilogram of the waste and results in a 70% minimisation in the waste. A survey of urban residents participating in these programs had a 70% satisfac tion level, further proving that the community is willing to participate in sustainable waste management. This work also reveals that composting strategies are useful in addressing the increasing problems of urban organic waste while lessening the effects on the environment and encouraging the growth of innovations in urban agricultural practices. Further studies should be conducted to look at how these techn
