Energy efficient pilot-scale production of wood fuel pellets made from a raw material mix including sawdust and rapeseed cake

► This work investigates the effect of mixing the pellets raw materials sawdust and rapeseed cake. ► The main purpose was to examine how the raw material mixture affected the durability of pellets. ► The energy consumption decreased and the amount of fines increased with increasing rapeseed cake. ► This indicate that we must compromise between a decrease in energy use and a decrease in durability.
