摘      要：With the substantial increase in solid waste due to industrialization and urbanization,the environmental damage has also aggravated,making the management of solid waste an important issue throughout the *** warming,species extinction,imbalance in nutrient cycle and random disposal of hazardous waste are some environmental problems threatening sustainable *** solid waste from the study area mainly consists of organic waste(66%),recyclables(25%) and miscellaneous waste(9%).About 10% of the organic waste is composted by public facilities funded by the government;whereas the entire miscellaneous waste is dumped at dumping sites without going through any *** 41% of the recyclables are sold to junk shops by households,and 28% are sorted out by scavengers at dumping *** EASEWASTE model is used to evaluate the impacts of existing solid waste management system on *** major gases which contribute to life cycle impact assessment are carbon dioxide(CO),methane(CH4),nitrous oxide(NO),CFCs(CFC-11,CFC-12,CFC-113,CFC-114 and CFC-115),HCFCs(HCFC-22,HCFC-123,HCFC-124 and HCFC-141 b),HFCs(HFC-125,HFC-134 a and HFC-152 a),halons,tetra chloromethane(CCl),1,1,1-trichloroethane(CClCH) and carbon monoxide(CO),and global warming potential is calculated by the EASEWASTE model at different timelines,i.e.20,100 and 500 years,*** toxicity via water and air is also evaluated and it found that the existing system is polluting the environment in many ways.
