Abstract

The paper focuses to introduce a sustainable Food Waste (FW) management framework to facilitate an efficient FW segregation from other types of waste in Municipal Solid Waste (MSW) through an optical sorting system, valorization to biogas via Anaerobic Digestion (AD) and further for power generation considering Karachi as a case study. For sustainable resolution to the acute waste disposal issue, a frame work for food waste collection, sorting and recycling is proposed considering the current waste management practices and local government policies. The process for obtaining biogas fuel from food waste has been widely practiced by many countries like Norway, Sweden and France. This study indicates the forecast for energy production from biogas which may reach to 994 GWh by the year 2030 in Karachi. Thus, this proposed management framework can bring the epitome of the waste to wealth concept for the sustainable collection and recycling of food waste to renewable energy in order to facilitate the clean environment and may result in reduction of reliance on landfills, promote circular economy and lessen the energy gap between power demand and supply in Karachi city.
