Abstract
A method for conversion of food waste to biofuel can include a first fermentation in which food waste is converted C-Cshort-chain carboxylic acids, and a second fermentation in which the C-Cshort-chain carboxylic acid are elongated into C-Cmedium-chain carboxylic acids. Medium-chain carboxylic acids can undergo hydrogenation-dehydration of the medium-chain carboxylic acids into C-Clinear olefins. The C-Clinear olefins are then oligomerized to a C-Cmixture comprising olefins, paraffin, cycloparaffins, and aromatics through dimerization; and saturated to C-Cmixture by hydrogenation to produce the biofuel.
