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.

A fuel production system includes a first modular unit and a second modular unit. The first modular unit includes a first housing, a process vessel, an agitator rotor assembly, a first drivetrain, an extrusion screw, a second drivetrain, a first separation vessel, and a product shaping system. The second modular unit includes a second housing, a thermal fluid heater system, a condenser, a second separation vessel, and a vacuum pump. The second modular unit is configured to be coupled to the first modular unit. At least a portion of each of the process vessel, the agitator rotor assembly, the first drivetrain, the extrusion screw, the second drivetrain, the first separation vessel, and the product shaping system are contained in the first housing. At least a portion of each of the thermal fluid heater system, the condenser, the second separation vessel, and the vacuum pump are contained in the second housing.

An system for processing biomass comprising a stator, a rotor having an axis of rotation, the rotor being disposed inside the stator and configured to rotate about the axis of rotation therein, a processing chamber defined between the rotor and the stator, an inlet in fluid communication with the processing chamber which is designed to introduce unprocessed biomass into the processing chamber, an outlet in fluid communication with the processing chamber which is designed to carry out processed biomass from the processing chamber and a pump operationally associated with the inlet and the outlet, wherein the pump is configured to pump the unprocessed biomass through the processing chamber.

A reactor (16) for the remediation of polyfluoroalkyl- and/or microplastic-contaminated feedstocks includes an elongated, horizontally oriented, axially rotatable drum (34) having a shell (72) within a housing (32), with a feedstock input assembly (38) adjacent one end of the drum (34) and a feedstock output assembly (40) adjacent the opposite end thereof. A burner (94) within the housing (32) generates hot combustion gases which surround the drum (34) in order to conductively heat feedstock passing through the drum (34). The invention substantially completely remediates the feedstocks through volatilization of the contaminants.

The invention relates to the use of pellets comprising one or more thermoplastic material(s) of more than 40%, based on the total dry weight of the pellets and one or more cellulosic material(s) of more than 20%, based on the total dry weight of the pellets, as a reducing agent in a process for making pig iron in a blast furnace. Said pellets can be provided in unground form, as a partial replacement of coke through the top of the blast furnace, or can be provided as reducing agent in the raceway in an amount of higher than 10 kg/ton iron.

A process and system for producing an engineered fuel product that meets customer specifications for composition and combustion characteristics is provided. The engineered fuel product is preferably a high-BTU, alternative fuel that burns cleaner than coal or petroleum coke (petcoke) and has significantly reduced NOx, SO.sub.2 and GHG emissions.

The present invention concerns a method for the removal of inorganic components such as potassium, sodium, chlorine, sulfur, phosphorus and heavy metals, from biomass of rural or forest or urban origin or even mixture of different origin biomasses, from low quality coals such as peat, lignite and sub-bituminous/bituminous coals, from urban/industrial origin residues/wastes, which are possible to include as much organic>5% weightas inorganic<95% weightcharge and from sewage treatment plant sludges. The desired goal is achieved with the physicochemical treatment of the raw material. The method can also include the thermal treatment, which can precede or follow the physicochemical one. The application of the thermal treatment depends on the nature and the particular characteristics of each raw material as well as on the feasibility analysis of the whole process in order to determine the optimization point in each case.
