In recent years, Malaysia has been facing an alarming situation of municipal solid waste (MSW) issue that is becoming worse to date. Population growth is causing Malaysians to also have increasing domestic waste generation that has exceeded 200,000 tons per month. Management systems for waste disposal is very limited, and the main approach in Malaysia is landfilling which has many problems including little to no leachate treatment. This paper presents a proposal to add benefit to the MSW to be a new precursor to produce activated carbon that can be used to replace non-renewable fuels such as coal and crude oil as a precursor, for leachate treatment. In this study, the composition of MSW used were 77.6% organics and food waste, and 22.4% plastics. The proximate analysis shows that the MSW is suitable to be used as a precursor to produce activated carbon due to its high carbon content which is 45%. Physical activation method was implemented by heating the MSW-derived carbon using CO2 gas at 700 – 900°C. After activation, morphology of the MSW-derived activated carbon indicates a presence of pore structure. From this study, it has been observed that the higher the activation temperature, the greater the surface area and pore volume of the MSW-derived activated carbon. The average pore size of MSW-derived activated carbon was less than 5 nm, that would be able to filter out heavy metals found in the leachate which has an average diameter of 10 nm, hence suitable to be used for leachate treatment.
