Study the factors influencing the production of ethanol from waste coconut water

Abstract

Currently in Sri Lanka, coconut water is a waste from Desiccated Coconut (DC) industry apart from the small quantity used to produce beverage and vinegar. BOD and COD value of coconut found to be 13,000-15,000 mg/1 and 40,000 mg/1 respectively while the effluent water contains 6000-10.000 mg/1 and 17,000-20,000 mg/1 respectively [3]. A local DC factory processes around 30,000-50.000 coconuts per day. It is mandatory to treat the effluent water in a waste water treatment plant in order to meet the water discharge standards. Value addition is obviously an important and worthwhile option for waste coconut water from the DC mills.
