Abstract

A method for production of fuel pellets or briquettes from surplus lignocellulose containing biomass of tree material used in a Kraft pulping process. The method comprises separating (21) the tree material into wood material and surplus lignocellulose containing biomass, processing (22) the wood material in the Kraft pulping process to produce pulp, withdrawing (23) at least one effluent from the Kraft pulping process to a waste water treatment plant, treating (24) the at least one effluent to obtain at least one sludge, reducing (25) the water content of the at least one sludge to obtain dewatered sludge, adding (29) at least a portion of the dewatered sludge to at least a portion of the surplus lignocellulose containing biomass to obtain a biomass and sludge mixture, and densifying (210) the mixture to form fuel pellets or briquettes.
