Energy recovery from Municipal Solid Waste in Mauritius is considered as a solution to enhance the country's energy security and tackle imminent waste management issues. This study applies an Analytical Hierarchy Process model for identifying the best waste to energy technology, which can be set up in Mauritius while taking into consideration technical as well as sustainability indicators. Incineration, gasification, pyrolysis and anaerobic digestion, were considered for the purpose of this study. As a result of the analysis, anaerobic digestion was ranked as the prioritised technology when social acceptance indicator, identified as the critical criterion, was attributed a high weight. When the effects of the critical criterion was either attenuated or eliminated during the sensitivity analysis, incineration emerged as the preferred technology. A critical analysis revealed that higher environmental and economic gains are expected to be generated as a result of implementing incineration for energy recovery in Mauritius. Finally, a review of the barriers hampering the implementation of an incineration plant in Mauritius demonstrated that the uptake of this technology is constrained by social acceptability. However, if proper awareness is conducted, energy recovery from municipal solid waste using incineration technology can become an interesting project for the Mauritian economy.

毛里求斯从城市固体废物中回收能源:机遇与挑战

从毛里求斯的城市固体废物中回收能源被认为是增强该国能源安全和解决迫在眉睫的废物管理问题的解决方案。这项研究采用了一种分析层次过程模型来确定最佳的能源浪费技术,该模型可以在毛里求斯建立,同时考虑技术和可持续性指标。焚化,气化,热解和厌氧消化被认为是本研究的目的。分析的结果是,当社会认同指标被认为是高标准时,厌氧消化被列为优先技术。当灵敏度分析过程中关键标准的影响减弱或消除时,焚烧便成为首选技术。一项关键分析表明,由于在毛里求斯实施焚化以回收能源,预计将带来更大的环境和经济收益。最后,对阻碍在毛里求斯实施焚化厂的障碍进行了审查,结果表明,这项技术的采用受到社会认可度的限制。但是,如果进行了适当的认识,使用焚化技术从城市固体废物中回收能源将成为毛里求斯经济的一个有趣项目。对阻碍在毛里求斯实施焚化厂的障碍进行的审查表明,这项技术的采用受到社会认可度的限制。但是,如果进行了适当的认识,使用焚化技术从城市固体废物中回收能源将成为毛里求斯经济的一个有趣项目。对阻碍在毛里求斯实施焚化厂的障碍进行的审查表明,这项技术的采用受到社会认可度的限制。但是,如果进行了适当的认识,使用焚化技术从城市固体废物中回收能源将成为毛里求斯经济的一个有趣项目。
