### Energy Valorization of Solid Coffee Waste by Thermal Gasification in a Pilot Plant

P.S.D. Brito, A.S. Oliveira & L.F. Rodrigues
Rapid and continuous depletion of fossil fuels resources and increasing concerns with environmental issues determines the urgent need for alternative fuels, particularly biofuels obtained from biomasses of different origins. In fact, biomasses are among the most abundant energy renewable sources and can be obtained in high amounts by the use either of bioenergetic crops or forest and industrial biowastes. Thermal gasification of solid biomass appears to be a promising process for syngas production containing methane...
