几十年来，利用城市固体废物(MSW)生产能源已在全球范围内实施。然而，马来西亚仍然高度依赖垃圾填埋场来管理城市生活垃圾。由于对温室气体(GHG)排放和土地稀缺的担忧，马来西亚迫切需要更好的废物管理战略。本研究旨在评估垃圾转化为能源(WTE)对城市生活垃圾管理的能源、经济和环境(3E)影响。选择马来西亚现有的一个垃圾填埋场作为案例研究，考虑采用先进的垃圾处理技术，包括垃圾填埋气回收系统(LFGRS)、焚烧、厌氧消化(AD)和气化。该研究对不同的WTE方案进行了互动比较，并进一步讨论了废物焚烧和AD作为马来西亚两种潜在的WTE备选方案的问题。3E评估显示，当考虑发电和制热时，焚烧是更好的技术选择；然而，仅考虑发电时，发现焚烧更有利。(C)2015爱思唯尔有限公司。保留所有权利。
The utilisation of municipal solid waste (MSW) for energy production has been implemented globally for many decades. Malaysia, however, is still highly dependent on landfills for MSW management. Because of the concern for greenhouse gases (GHG) emission and the scarcity of land, Malaysia has an urgent need for a better waste management strategy. This study aims to evaluate the energy, economic and environmental (3E) impact of waste-to-energy (WTE) for municipal solid waste management. An existing landfill in Malaysia is selected as the case study for consideration to adopt the advanced WTE technologies including the landfill gas recovery system (LFGRS), incineration, anaerobic digestion (AD), and gasification. The study presented an interactive comparison of different WTE scenarios and followed by further discussion on waste incineration and AD as the two potential WTE options in Malaysia. The 3E assessment reveals incineration as the superior technology choice when the production of electricity and heat were considered; however, AD is found to be more favourable under the consideration of electricity production only.
