ABSTRACT In developing Asian countries, the municipal cooperations are unable to handle the increasing amount of municipal solid waste, which into the uncollected waste being spread on roads and in other public areas leading to tremendous pollution and destruction of land and negative impact on human health. Generation of municipal solid waste increases with the rapid urbanization and accelerated economic development with in the rapidly growing advanced technological societies. The nature of municipal solid waste is a term usually applied to a heterogeneous collection group of waste produced in urban areas, the nature of which varies from region to region. The common problem faced by all developing Asian countries, is the disposal of municipal solid waste and availability of land fill site area. Present study explains the correlation analysis of among different factors of municipal solid waste and the objective is to assess the future municipal solid waste stream in Asian developing countries. The other goal of this study was to calculate the future land area that would be required for landfill site disposal in Asian developing countries.

    ABSTRACT: Since, landfill areas are still the most widely used solid waste disposal method across the world, leachate generated from landfills should be given importance. Leachate of landfills exerts environmental risks mostly on surface and groundwater with its high pollutant content, which may cause unbearable water quality. This leads to the obligation for decontamination and remediation program to be taken into progress for the landfill area. Among a number of alternatives to cope with leachate, one is to employ the technology of phytoremediation. The main objective of this study was to determine the N accumulation ratios and the effects of landfill leachate in diluted proportions of chosen ratios (as 1/1, 1/2, 1/4, 0), on the growth and development of Cynodon dactylon, Stenotaphrum secundatum, Paspalum notatum, Pennisetum clandestinum, Mentha piperita, Rosmarinus officinalis, Nerium oleander, Pelargonium peltatum and Kochia scoparia species. In order to simulate the actual conditions of the landfill, soil covering the landfill is taken and used as medium for the trials. The study showed that S. secundatum, K. scoparia and N. oleander species had an impressive survival rate of 100%, being irrigated with pure leachate, while the others' survival rates were between 0 to 35% under the same conditions. As expected, application of leachate to the plants caused an increase in the accumulation of N, in the upper parts of all plants except P. peltatum. The highest N content increase was observed at S. Secundatum set, accumulating 3.70 times higher than its control set, whereas P. clandestinum value was 3.41 times of its control set.

    ABSTRACT: Sustainability in waste management has been discussed since the last decade. However there is no consensus. Sustainability in one nation may not apply to another. There are many drivers affecting sustainability and the impact varies from one country to another, depending on political, socio-economic and environmental factors. The scenario is more complicated in Asia due to rapid industrialization and urbanization and changing waste composition and generation rates. Waste management technologies are generally conservative in Asia and the need for integrated waste management is imperative. Impact of waste management could be local, regional or global as can be seen in climate change and environmental degradation.

    ABSTRACT: The present scenario of municipal solid waste management (MSWM) in four study countries of Asia - namely China, India, Sri Lanka and Thailand is highlighted comparing technical, economic, legal and, health issues. An overview of various aspects of the municipal solid waste (MSW) is provided comprising all domestic and non- hazardous wastes in the urban areas of the above countries with emphasis on the generation and composition of MSW, management needs, collection systems practiced, transportation and disposal systems used. The collections systems and their lacunae, the recycling practiced with respect to the involvement of the government and the private sectors are underlined. Disposal methods in India and Thailand find mention in particular for landfill and incineration. Other issues taken up are the effects on MSW due to cultural aspects and climatic variations. Further to that it is reflected on the public awareness and participation of the community in MSWM as well as the involvement of the NGOs and the private sector. Finally, the emerging trends with respect to the integrated solid waste management (ISWM) have been discussed.
