Waste management in Malaysia remains a persistent economic and environmental challenge. Up to date, more than 80% of Malaysian solid waste disposed at landfills and dumpsites. Therefore, Malaysia is facing an urgent need to move towards a sustainable solid waste management and thus resource recovery from organic solid waste. Hence, this study aims to investigate the feasibility of energy and bio fertilizer recovery from organic fraction municipal solid waste (OFMSW) via anaerobic digestion. The economic and environmental benefit analysis was investigated. Approximate and elementary analysis of OFMSW samples were carried out to estimate the potential production of biogas and bio fertilizer. It was found that organic waste contributes about 45% of the total MSW generated in Malaysia. Anaerobic digestion of 50% of organic waste is expected to produce 3941 MWh/day of electrical energy and 2500 t/day of bio fertilizer. In terms of environmental impacts, 2735 t/day of Carbon dioxide (CO₂) emission, 1128 m²/day of landfilling area and 481 m³/day of leachate can be avoided. A net revenue of 3300 million RM (1 US Dollar ≈ 4.15 RM) can be generated by the sales of electricity via Feed-in-Tariff (FiT), sales of biofertilizer to local agricultural industries and inclusive of the saving generated from the reduction of OFMSW landfilling operations and leachate treatment at landfills. Economic development can go hand-in-hand with environmental sound practices in the field of waste management.

马来西亚的废物管理仍然是持续的经济和环境挑战。迄今为止，马来西亚80％以上的固体废物都被丢弃在垃圾填埋场和垃圾场。因此，马来西亚迫切需要实现可持续的固体废物管理，从而从有机固体废物中回收资源。因此，本研究旨在研究通过厌氧消化从有机部分城市固体废物（OFMSW）中回收能源和生物肥料的可行性。进行了经济和环境效益分析。对OFMSW样品进行了近似和元素分析，以估算沼气和生物肥料的潜在产量。研究发现，有机废物约占马来西亚城市固体废弃物总排放量的45％。厌氧消化50％的有机废物预计将产生3941 MWh /天的电能和2500吨/天的生物肥料。就环境影响而言，每天2735吨二氧化碳（CO₂）可以避免排放，避免了1128 m ² /天的垃圾填埋场和481 m ³ /天的渗滤液。通过上网电价（FiT）的电力销售，向当地农业的生物肥料销售以及包括减少农业生产所产生的节余，可以产生33亿林吉特（1美元≈4.15马币）的净收入。 OFMSW垃圾填埋场操作和垃圾填埋场渗滤液处理。经济发展可以与废物管理领域的环境无害实践并驾齐驱。
