Abstract

Solid waste management is a tedious process in developing countries. Unscientific disposal of solid wastes leads to severe environmental disasters and health problems. The states which have a burden over the environment and public health are considering environment-friendly and cost-effective mechanisms for solid waste management. The solid waste management issues have already become very severe in cities and towns as the disposal facilities are geared to a large amount of waste generated. The explored mechanisms include vermicomposting and organic waste digestion by the larvae of black soldier fly. As the composition of decayed matter varies due to physicochemical and biological components, the physicochemical and biological parameters in decomposing solid waste are important. A vast number of studies were already carried out recently on solid waste management in the western region. Hence, the present study is focused on exploring fluctuations of temperature and Stratiomyidae larval density of composting in a tropical climate. The research was carried out in 2 stages. In the first stage, a preliminary study was conducted to find out whether the addition of garden waste to composting kitchen waste has affected the dipteran larvae that colonize the compost. The preliminary study showed that with the addition of garden leaves into the unit the abundance and the diversity of fly larvae go down drastically. Therefore, in the second stage, the proper study was carried out without adding any garden wastes and using kitchen waste only. It is concluded that the increase in temperature leads to microbial activity while fly larval activity indirectly enhances microbial activity which promotes composting.
