Abstract: The invention relates to a method for processing a mixture of cellulose/plastic waste particles comprising cellulose and thermoplastic materials. The thermoplastic material constitutes at least 10 weight% of the total weight of the waste mixture The cellu-lose/plastic waste mixture is first dried by treatment with a medium with a temperature in the range of 50 to 150 ° C., wherein the exit temperature of the drying medium has a temperature of 115 ° C. or less. The dried cellulose/plastic waste mixture is then fed to a purification stage, and subjected to the operation of the purification stage. The purification stage comprises at least one separator selected from the group of: wind separator, sieve, metal separator, separator for separating out chlorine- containing components, or a combination thereof.

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.
