Abstract

Abstract: Industrial ecology based symbiotic system approach is applied to Indian municipal solid waste (MSW) for population size of one million, taking various alternative techniques: anaerobic digestion (AD), compost, refuses derived fuel (RDF), incineration and gasification. Considering the virtual operation of the existing plants for production of electricity and products, the economic and environmental evaluation of each technique is presented. For environmental impact assessment global warming, acidification, photochemical oxidation and eutrophication categories are considered. The conceptual analysis depicts that AD has maximum tendency to reduce global warming (123 tonne CO2 eq./day) along with the economic benefits of 19099 INR/day (293 $/day). Gasification shows maximum reduction in acidification, photochemical oxidation and eutrophication by 189 kg SO2 eq./day, 33 kg C2 H4 eq./day and 12 kg PO4 eq./day with economic benefits of 46956 INR/day (722 $/day). Integrated operation of AD and gasification gives maximum economic benefits (INR 66056/day or 1016 $/day) with highest reduction in environmental impact (for all categories) as compared to a single technology and any other combination of technologies. Industrial ecology approach for MSW management system affects the economic and environmental results to significant level that can influence the policy and decision making. Graphical abstract: Image 1 Highlights: Discussed status of MSW, its various processing techniques and Government policy in India. Highlighted some economical factors that are vital for evaluation to identifying a sustainable MSW management system. Industrial ecology approach is applied to Indian MSW considering population size of one million. Comprehensively evaluated and compared five technologies in economic and environmental terms. Proposed a sustainable MSW management system in economic and environmental terms.
