The production of bioethanol from cellulosic waste is described. The experiment is suitable for students in secondary school classroom settings and leads to bioethanol in a concentration high enough to burn the liquid. The experiment consists of three steps: (i) the cellulose of the waste material is converted to glucose by cellulase enzymes, (ii) the glucose-containing solution is fermented by baker's yeast to a solution of approximately 5% ethanol, and (iii) the ethanol solution is subsequently distilled to yield an ethanol solution of at least 40%. All students obtained flammable end products and liked the realistic practice.
