Abstract
Waste disposal has become one of the major concerns for our Country, Nigeria. Fruit peels are the major solid by-product. The dried fruit peels have a content of cellulose and hemicelluloses, which make it suitable as fermentation substrate when hydrolyzed. This thesis aims at utilizing fruit (pineapple) peels for the production of bio-ethanol by using the yeast Saccharomyces cerevisiae, thus, producing a valuable product from the fruit peel wastes. The pineapple waste is collected and weighed. This is then grinded, mixed with about 2 litres of water and then filtered. The filtrate is heated on the stove for 5-6hours in which sugar syrup is obtained.
After this, fermentation process takes place which involve introducing 10ml of the yeast into the mixture and mixing with 100ml of water. The water is first boiled at 100°c for 30 minutes after which it was allowed to cool to around 37°c.
Finally, distillation process is being carried out. The cold mash is put into the combustion chamber and heat is applied from a stove and a copper pipe connected through the condenser Chamber, thermometer, and cork fitted to the collection chamber. Re-distillation is carried out to increase the ethanol content.
