Singapore, with a land area of 659.9 square kilometers, houses a population of close to 4.19 million people that generated 2.63 million tonnes of municipal solid waste in 2002. Of this amount, food waste and horticultural waste collected contributed 19.6% (or 0.94 million tonnes) of total waste collected. To improve the management of Singapore's organic solid waste disposal, this study was conducted to assess the feasibility of applying the two-stage integrated anaerobic/ aerobic process as an alternative to its adopted processes. The scope of this study included a review of the anaerobic/aerobic process, its potential and limitation for application in Singapore and comparisons of processes that are currently employed for municipal solid waste management.
