Fruit residues may cause serious environmental problems, since it accumulates in agro-industrial yards without having any significant and commercial value. Since disposal of these wastes is expensive due to high costs of transportation and a limited availability of landfills they are unscrupulously disposed causing concern as environmental problems. Furthermore, the problem of disposing by-products is further aggravated by legal restrictions. A high level of BOD and COD in pineapple wastes add to further difficulties in disposal. Researcher have focused on co-digestion of pineapple waste along with several other fruit and vegetable wastes, manure, and slaughter house wastes to reduce volatile solids by 50 to 65% (Alvarez and Liden, 2007). Recently, composting of pineapple wastes using earthworm is reported (Mainoo et al., 2009). They have reported that vermicomposting rapidly decomposed about 99% of pineapple pulp wet mass while peel had a loss in weight by almost 87%. The pH of the waste changed from acidic to a neutral to alkaline during composting. However, cost effectiveness is yet to be studied.
