Abstract

Abstract:Solid wastemanagement is a basic and integral part of human living. All over the globe 1.3billion tons per year municipal solid waste (MSW) is generated which isexpected to increase up to 2.2 billion tons per year by 2025, against which0.0365 billion tons per year is generated by India alone. Solid waste ismanaged by local bodies of countries or states involving steps of collection,processing, transportation, recycling and disposal of solid waste. However, inmost of the countries, factors such as lack of infrastructure, financialsupport and technology which are not up to the required level leading toinefficient waste management services. Further, since construction is one ofthe basic need for development and GDP growth for any country, thus governmentpolicies are promoting rapid construction growth. This rapid constructiongrowth with the lack of infrastructure for waste handling is contributingabnormally for waste generation during any construction, maintenance and demolitionphases of a building. Thisstudy reviewed and applied the concept life cycle assessment (LCA) which is aparameter of green rating tool and which can be followed for a building by anygovernment and private body. Benefits of implementing the concept life cycleassessment can then be compared with conventionally constructed buildings. Theresults can be used for policy decisions as well as strategic decisions onwaste management systems during building planning phase only which will notonly help in reducing the waste generation by reusing but also save cost andtime for disposal activities. It has been observed that by simply adopting thesteel material in place of concrete for building frame construction, thereduction in the overall total municipal solid waste can be made by 3.96percent.
