From studies conducted by several research groups indicated that waste from most municipalities and universities in Thailand fell among 5-20 tons per day which was too small to economically generate electricity. Recommended strategy is: 1) to enhance separation of useful waste upstream, 2) to preliminarily separate remaining useful waste at a collecting center, 3) to employ aerobic fermentation of remaining organic waste for producing organic fertilizer, and 4) to use rather clean plastic waste left after separation of organic fertilizer in order to produce second-hand plastic granule, or to use as fuel if possible or to produce liquid fuel but still at high cost.
