Development of a sustainable environmental preservation Centre (EPC) at Nawalapitiya for urban solid waste Management

Abstract

An Environmental Preservation Centre (EPC) was established to resolve the solid waste management crisis of Nawalapitiya Urban Council. Material Recovery Facility (MRF), Inclined Step Grate (ISG) composting system of 5.5 tonnes/ day capacity, screening, storage and residual landfill, the total area covered by the fence including buffer zone are the major components of the EPC. After separating recyclables at the MRF, the remaining biodegradable is fed in to ISG system. Residual landfill is designed for inert materials that are remaining after the MRF and composting facility operations. MRF and ISG system are already constructed and currently initiated the operations. This is technically and financially feasible sustainable approach for protecting the environment and posterity.
