A research innovation on product development through principle of applied biotechnology was demonstrated for production of ethanol bio gel, an alternative cooking energy source. Bio ethanol was produced using pretreated sawdust as substrate by solid state fermentation technique using Aspergillus niger. The bio ethanol was further used in a combination with water and a nitrosol compound in a ratio (70:10:20) for production of ethanol biogel. Preliminary analysis showed that the ethanol biogel had the following properties; viscosity at 40oC and 80oC recorded (421.20cst and 210.87cst respectively), flashpoint (26oC), density at 25oC (0.908kg/m3), total acid number (0.12mgKOH/g), pour point (-13% still flowing) with pH 6.16 having no base settlement and no water content. The flame produced was thinner compared to kerosene and wood flames. It also had a blueish colour full of motion, also odourless with complete combustion.
