Municipal solid waste generation and disposal is a problem not only in India but all over the world. Presently majority of such waste is being dumped indiscriminately over vacant lands causing problems of odor, methane generation leading to air pollution, leaching effect polluting ground water and runoff polluting water bodies. Technological options are available to treat this solid waste and convert it into usable products but the biggest problem is its segregation preferably at the source of generation or even at the disposal area. Municipal solid waste generated in India consists of 15 percent non biodegradable which has high calorific contents and can be converted into power generation. Remaining 85 percent is degradable which can either be converted into compost or bio fuels. Under the present context, sustainable municipal waste management strategy needs to be evolved and put in place with effective implementation to address the issue of environmental pollution. An attempt has therefore been made by the authors of the present paper to take up a case study of Kanpur, India for managing such wastes having sustainable approach. The authors have worked out trends of population starting from the year 1951 and projected to 2051. Similarly waste generation trends established on the lines of population. An effort has also been made as to how much compost, bio fuel and power can be generated along with economic value to make it sustainable on a time scale.

The problem associated inappropriate management of municipal waste to the ecosystem cannot be overemphasized. This study involved the physical characterization of municipal solid waste streams in 4 commercial dumpsites in Yenagoa Metropolis, using the quartile estimate method. Results showed that out of a total mass of 79.82kg; the individual mass composition was reported for garbage (food) waste 33.32 (39%), paper waste 14.90 kg (40.82%), plastic waste 5.12 kg (6%), nylon 11.01kg (13%), metal 4.31 kg (5%), wood 2.29 kg (3%), electronic 5.69 kg (7%), glass/ceramic 3.48 kg (4%) and unclassified waste whose mass was 4.62kg (5%). Disposal of untreated and unsegregated/uncharacterized waste adverse effect to the environment. It is hereby recommended that the populace to desist from illicit disposal of waste stream. In addition all stakeholders and Government in particular should formulate policies the reduction, reuse and recycling of waste stream.
