Zusammenfassung:The invention relates to a method of making pelletized fuel containing plastic and cellulose particles in which a feed stream containing plastic and cellulose particles is supplied to a pelletizing device. The invention relates to a method of making pelletized fuel containing plastic and cellulose particles in which a feed stream containing plastic and cellulose particles is supplied to a pelletizing device.The process is used in particular in processes for recycling household and industrial waste streams into pelletized fuel. The invention also relates to pelletized fuel, to the use of the pelletized fuel as secondary fuel and to various methods of firing furnaces with the pelletized fuel. The process according to the invention is characterized in that the feed stream contains at least 40 wt. % plastic and the pelletizing device has an annular mould with holes whose effective hole length (L) and hole diameter (D) ratio (R) is at least 5. Besides a high calorific value, the pelletized fuel obtained has a good hardness, good bulk, storage and transport properties and a good grindability.
