CIRCULAR ECONOMIC MODEL OF INTEGRATED WASTE MANAGEMENT: A CASE OF EXISTING WASTE MANAGEMENT IN POPULATED URBAN AREA

The current waste management system does not only focus on environmental issues but also on social and economic aspects. Therefore, an integrated solid waste management system (ISWMS) has been widely implemented; however, most of the implemented systems have been addressed issues partially in such factors as technology or informal sector involvement. This study integrates three groups directly involved in waste management system particularly in developing countries comprising the government, the society, and the informal sector. This type of integration is believed to be able to reduce waste in the source, improve the waste pickers' income, and enhance regional waste management performance leading to the decrease of environmental pollution. In addition, maximizing waste reduction through recycling processes is also likely to lead to circular economy which is proven to efficiently save virgin natural resources. This study employed a dynamics system using Powersim 10 software. The simulation results showed that waste reduction in the source significantly enhanced, income of the informal sector increased, waste management performance improved yet the budgeting decreased, and exploitation of virgin natural resources decreased.
