Abstract

Malaysia is composed of the Peninsular Malaysia and the states of Sabah and Sarawak in the island of Borneo. As a country that moving forward to achieve the industrialized country status by the year 2020, Malaysia cannot escape from facing the solid waste management problems. There are a total 230 landfill in Malaysia. Landfills have been the most common methods of organized waste disposal. In most cases, open dumping is being practiced and takes place at about 50% of the total landfills. In addition, many landfills have opted to close rather than meet new while the quantity of waste generated yearly is much faster than the natural degradation process. Last year, about 7.34 million tones of solid wastes were generated, enough to fill up 42 buildings the same size as that of the world-renowned Petronas Twin Tower. Which each person generates about 1kg of solid waste per day. This solid waste volume is still increasing at the rate of 1.5% per year due to increase in urbanizations, change in living standards and consumption patterns. The case study, Ampar Tenang Landfill is situated near Sungai Labu, Sepang. Due to the continuous domestic waste generation, Ampar Tenang Landfill also currently overloading and serious leacheate spilling over the adjacent areas to the nearby Sungai Labu which is the main water supply for the Sepang and Nilai locality. Majority of the landfills in Malaysia are crude dumping ground, thus cause natural resource polluted and various environmental problems such as health hazards, surface water and ground water contamination, odors, etc. There are other treatment and/or disposal methods such as incineration and composting which could moderate the solid waste problems but they are not economically and socially viable at this moment. Thus, waste reduction, recovery and recycling play important roles in tackling the pressing solid waste problems.
