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
