The ethanol productivity of cassava crop (variety TMS 30555) and the methane productivity of its waste product (peels) mixed with livestock wastes were investigated in laboratory experiments, and the capability of tropical countries in this respect was computed. Cassava tubers were peeled, cut and washed. Five, 15, 25 and 35kg samples of the tubers were weighed in three replicates, soaked in water for a period of 1day, after which each sample was dried, crushed and the mash mixed with 500ml of N-hexane (C6H14). This crushed mash was then allowed to ferment for a period of 8days and afterwards pressed on a 0.6mm aperture size sieve to yield the alcohol contained in it. This alcohol was heated at 79 o
