modeling barriers of solid waste to energy practices: an indian perspective

in recent years managing solid wastes has been one of the burning problems in front of state and local municipal authorities. this is mainly due to scarcity of lands for landfill sites. in this context experts suggest that conversion of solid waste to energy and useful component is the best approach to reduce space and public health related problems. the entire process has to be managed by technologies that prevent pollution and protect the environment and at the same time minimize the cost through recovery of energy. energy recovery in the form of electricity, heat and fuel from the waste using different technologies is possible through a variety of processes, including incineration, gasification, pyrolysis and anaerobic digestion. these processes are often grouped under “waste to energy technologies”. the objective of the study is twofold. first authors assessed the current status of solid waste management practices in india. secondly the leading barriers are identified and interpretive structural modeling technique and micmac analysis is performed to identify the contextual interrelationships between leading barriers influencing the solid waste to energy programs in the country. finally the conclusions are drawn which will assist policy makers in designing sustainable waste management programs.
