Abstract

Techniques, systems, apparatus and material are disclosed for generating oxygenated fuel. In one aspect, a method of producing an oxygenated fuel from biomass waste for use in a combustion system includes dissociating the biomass waste to produce one or more carbon donors. The biomass waste produced carbon donors are reacted with an oxygen donor to produce the oxygenated fuel comprising oxygenated carbon. Reacting the carbon donors with the oxygen donors includes applying waste heat recovered from an external heat source to the reaction of carbon donors and oxygen donor. The oxygenated fuel is combusted in the combustion system.
