摘要

本研究旨在计算与现有的垃圾填埋处理方法相比，垃圾分类做法可避免的沥滤液量和处理成本。数学公式用于分析废物分类率、沥滤液量和处理成本。研究结果显示，99.4% 的混合垃圾被填埋处理，每年产生 56.5 万立方米的沥滤液，估计处理成本为 1982 万马来西亚令吉（436 万美元）。垃圾分类仅占 0.06%，却减少了 354 立方米的沥滤液，每年节省处理费用 1.242 万马来西亚令吉（273 万美元）。研究结果认为，垃圾分类做法可以减少沥滤液的产生和处理成本以及对环境的影响，从而降低垃圾管理成本。

Estimation of Leachate Volume and Treatment Cost Avoidance Through Waste Segregation Programme in Malaysia

This study aims to calculate the avoided leachate volume and treatment cost from waste segregation practices compared to the existing waste disposal methods of landfilling. The mathematical equations were used to analyse the waste segregation rate, leachate volume and treatment cost. The study findings reveal that 99.4% of mixed waste was disposed of in landfills, resulting in an annual generation of 565 thousand cubic meters (m3) of leachate with an estimated treatment cost of MYR 19.82 million (USD 4.36 million). The segregated waste, which accounts for only 0.06%, reduces 354 m3 in leachate volume and a cost-saving of MYR 12.42 thousand (USD 2.73 thousand) in the treatment expenses per year. The findings concluded that waste segregation practice could reduce waste management costs by reducing leachate production and treatment costs and environmental impacts.
