Abstract

The Malaysian inhabitants has been growing at a rate of 2.4% per annum or about 600,000 per annum since 1994.So, the municipal solid waste (MSW) generation also increases, which makes MSW management vital. In 2003, the average amount of MSW generated in Malaysia was 0.5-0.8 kg/ person/day. And, by the year 2020, the quantity of MSW generated was estimated to have increased to 31,000 tons. Currently, landfilling is the only method used for the discarding of municipal solid waste in Malaysia, and the majority of the landfill sites are open dumping areas, which causes severe environmental and social threats. So, the aim of this study is taking into account the present condition of disposal options in Selangor state regarding environmental point of view. Life cycle Analysis is a method which is used to consider disposal methods. In this Article life cycle assessment tool is used to weigh up different treatment scenarios with Eco-indicator (Europe 99) methodology which is applied to model different scenarios. Research, showed that all scenarios has a high amount of different potential impacts, Otherwise analysis illustrated first scenario which is the existing condition of Malaysian disposal method, is not preferable than others because of its high contribution on climate change, respiratory organics and carcinogens. Scenario 3 also has high impacts on respiratory inorganic, ecotoxicity and acidification. In addition, second scenario has the average impacts and its situation is between S1 and S3. However, environmental impacts of disposal methods could be considered by decision makers in future and it should be completed by different solid waste management methods and defining different scenarios in the country to introduce the most environmentally and economic method to the authorities.
