Description: The growing consumption of young coconut has resulted in an increased generation of by-products such as husks and shells that are dumped on embankments and left in the open field as waste. The young coconut husk extract has an initial sugar concentration of 5 0Bx to 7 0Bx and available moisture of 30 % extracted per 1000 gram of husk. The process of producing bioethanol from young coconut husks extract includes shredding, extracting, boiling/concentrating, fermenting, and distilling. Different processes accompanied by design, fabrication, and evaluation of machines in the study was done. Young coconut husks shredder was evaluated having a capacity and efficiency of 100.95 kg.hr-1 and 90.53 %, respectively. Young coconut husks juice extractor has a capacity, extraction rate, and juice recovery of 145.67 kg.hr-1, 52.05%, and 36.11%, respectively. Saccharomyces cerevisiae was used in the fermentation process. Extraction of shredded husks extracts by mechanical pressing without undergoing destructive methods such as boiling or addition of acids will preserve the quality of coconut fiber that can be later used for the development of other value-added product like ropes. The study reveals that to produce one (1) L of bioethanol, an equivalent of 64 kilograms of young coconut husks at 16 0Bx was needed. It entails a large amount of feedstock to produce a liter of bioethanol but considering the dilemma in fossil fuel and greenhouse gas emissions, a feedstock that does not compete in food production, renewable, and available all year round can contribute to the production of bioethanol.
