A method for producing a gasifier feedstock with uniform gasification characteristics from a number of biomass sources which each exhibit differences in their drying, pyrolysis, devolatization or gasification characteristics. The method allows biomass from a wide range and sources and with a wide range of gasification characteristics to be utilized within a gasifier without modification of the gasifier unit. The method produces a fuel pellet with controllable size, density and moisture content. The method smoothes any changes in calorific value which may exist between different feedstocks. It has been found that the gasification characteristics of a pellet formed in this way is strongly dependant upon the shape, moisture content and density of the pellet formed and less sensitive to the origin of the biomass feedstock.
