Valorisation of organic fraction municipal solid waste via anaerobic co-digestion of Malaysia tropical fruit for biogas production

Abstract

The acceleration of MSW generation is one of the world's critical challenge that contributed to the serious environmental and socio-economic problems involving pollutions and shortage of waste disposal area. The population growth, economic growth and urbanization are the key contributors to the MSW generation. Precisely, organic waste is the world highest contributor of MSW compared to other inorganic waste. This massive amount of putrescible waste consumption has a great global warming potential through the unutilized methane gas released from the landfill. In this regard, the waste treatment method through energy recovery Organic Fraction of Municipal Solid Waste (OFMSW) via Anaerobic Digestion (AD) has become the best way to utilize the high valuable energy (methane) resource potential and sustaining the environment. Moreover, AD process could be further enhanced through co-digestion process with various of substrates. Malaysia tropical fruit are among the potential of substrate for the anaerobic co-digestion that receiving extensive attention. This short article reviewed the potential of the selected Malaysia tropical fruit residues as substrates for anaerobic co-digestion with OFMSW.
