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.

“…Pineapple is one of the Malaysian new sources of wealth with a total cultivation area of 16 thousand hectares [1]. The Malaysian pineapple market expanded to 28 million tonnes and is considered as one of Southeast Asia's leading pineapple exporters [2]. Pineapple leaves and peels are the main waste associated with pineapple commercialization, and almost a thousand tonnes of solid waste are produced Original Research every year.…”

Recent Updates on the Conversion of Pineapple Waste (Ananas comosus) to Value-Added Products, Future Perspectives and Challenges

“…About 80% of pineapple parts, including the crown, peels, leaves, core and stems, are discarded during pineapple processing, transportations and storage and ends as waste [10,55]. As one of the leading agricultural commodity producers in the Southeast Asian region [56], Malaysia produces 335,488 tons of pineapple in addition to 67,098 and 137,550 tons of leaf and peel wastes [57]. These wastes contain high moisture, sugar, albumins, lipids and vitamins that are prone to microbial spoilage thus contributing to environmental problems [6,58].…”
