In order to reduce and re-utilize the ethanol fermentation residue from food waste, this study utilized residues to produce solid biomass fuel and carried out burning test by thermal gravity (TG) analysis. The results demonstrated that the residue from food waste shared the characteristic of high volatile content, high heat potential, low fixed carbon and low ash content. The burnable content was about 86.99% based on dry mass, while the heat potential was 23.06 MJ•kg-1. Lignitous coal or blind coal was adopted as the additive to improve the burning characteristic of the fermentation residue. The result for a mixture of lignitous coal and residue was better than those of blind coal with the increase of complex burning index S from 2.38E-07°C-3•min-2 to 7.99E-08°C-3•min-2, decrease of ignition point, enhancement of average burning ratio and amelioration of burning characteristic. All these provided theoretical guidance for fermentation residue utilization as the solid fuel.
