摘要： The invention relates to a method for producing pellets which are capable of providing free flowing powder suitable for firing an industrial furnace from municipal and/or other waste, the process comprising the following steps: (i) providing waste material comprising one or more thermoplastic material(s) of more than 40%, based on the total dry weight of the waste and one or more cellulosic material(s) of more than 30%, based on the total dry weight of the waste, wherein the waste has a particle size distribution with more than 80% larger than 5 mm, more than 95% smaller than 60 mm, (ii) subjecting the waste material through a pelletiser with holes between 4-16 mm and a length ratio of more than 2, and subjecting the pellets through a second pelletiser with holes between 4 and 10 mm, and a length ratio of more than 2 to provide pellets with a diameter between 4 and 10 mm, and a length of between 3 and 50 mm. The invention also relates to pellets obtained and having advantageous properties.

摘要： The invention provides a process for producing cement, the process comprising providing heat to a cement manufacturing process using a secondary fuel, wherein the secondary fuel comprises cellulose and plastic and is in the form of pellets of a size between about 3-25 mm thickness, having a calorific value of about 16 GJ/ton or more, and wherein said secondary fuel is supplied at a place between the kiln inlet and the first cyclone, wherein after formation of the cement clinker, the cement clinker is cooled and milled to cement powder. Preferably, the secondary fuel is supplied to the riser pipe or to a pre-kiln combustion chamber. Generally, the secondary fuel is provided at a place which allows the pellets to burn before coming in contact with the cement materials in the kiln, while it also does not rise into the cyclone, thereby preventing blocking of the cyclones.

摘要： The invention relates to a process for firing an industrial furnace, in particular for electricity generation, wherein coal or cokes together with a secondary fuel comprising cellulose and plastic, in the form of pellets of a size larger than about 3 mm thickness, and having a caloric value of about 16 GJ/ton or more is ground to a powder wherein about 95 wt% or more has a particle size smaller than 2 mm and wherein the d50 of the particle size distribution is between about 5 and about 100 µm, wherein the powder is injected in the flame of the furnace. In this process the grinding is performed in a roller mill or ball mill, and the amount of pellets used together with the coals preferably is about 3 wt% or more, relative to the coal.
