Abstract: Method of making cellulose/plastic pellets in which a particulate cellulose/plastic mixture comprising more than 60 to 95 weight % of cellulosic material and 5 to less than 40 weight % of thermoplastic material, based on the total dry weight of cellulosic and thermoplastic materials, and 1 to 15 weight % of moisture, based on the total weight of the mixture, is supplied at a temperature T1 of at most 90° C. to a pelletizing device comprising an annular mould with holes having a diameter D of at most 8 mm and an effective hole length L to hole diameter D ratio R of at least 7, the values of R and T1 being chosen in relation to one another so that the temperature T2 of the pellets leaving the annular mould is between 80 and 125° C. and the T2-T1 rise in temperature is at least 10° C., and cellulose/plastic pellets obtainable by said method.
