The present invention provides a process for obtaining solid recovered fuel and synthesis gas from a waste-based feedstock, comprising the steps of: I. converting the feedstock into a solid recovered fuel by means of a number of parameters pertaining to waste sorting, selection, comminution and/or screening; II. gasifying under suitable reaction conditions at least a portion of the solid recovered fuel to produce synthesis gas and by-product(s); and III. optionally cleaning at least a portion of the synthesis gas to produce clean synthesis gas and wastewater, wherein one or more of the solid recovered fuel, synthesis gas, and by-product(s) of the gasification are analysed during operation of the process, and wherein data from said analysis is used to control one or more parameters of step I) in order to influence reaction conditions in step II, and optionally step III).

The present invention relates to a method for producing agglomerates from a feedstock comprising at least one biomass stream, the method comprising the steps of: combining the feedstock with one or more binding reagents; and introducing the feedstock into an agglomeration apparatus in the presence of a polymerisation activator to produce the agglomerates.

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.

A method and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance of said manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. Said bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, said bedding material is dried (without a compacting step) to form a product. In another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.

Provided is a method that produces a solid fuel having a relatively high strength from a powder fuel. The method includes: blending a coal-derived powder fuel with a pulverized fuel having a greater mean particle diameter than the coal-derived powder fuel to obtain a mixture; compression-molding the mixture to obtain a solid fuel; and pulverizing a part of the solid fuel, in which the part of the pulverized solid fuel is used as the pulverized fuel in the blending. A blending proportion of the pulverized fuel with respect to the blending mixture is preferably at least 5 mass % and at most 50 mass %. A cohesive fine coal having a superior cohesive property to the coal-derived powder fuel is preferably further blended in the blending. A blending proportion of the cohesive fine coal with respect to the blending mixture is preferably at least 5 mass % and at most 30 mass %.

A method for fractionating biomass material according to ash content, the method comprising: grinding the biomass material to produce a ground biomass and sieving the ground biomass through a first screen to yield: a) a first fraction of biomass particles that does not pass through the first screen and which has a first particle size, and b) a second fraction of biomass particles that passes through the first screen and which has a second particle size, wherein the second particle size is smaller than the first particle size, and wherein the second fraction of biomass particles has a higher ash content than the first fraction of biomass particles; and optionally further comprising: passing the second fraction of biomass particles through a second screen having a finer mesh size to produce a third fraction having a smaller particle size and a higher ash content than the second fraction of biomass particles.

Waste, such as municipal solid waste (MSF), is separated into a wet fraction and refuse derived fuel (RDF). For example, the waste may be separated in a press. The wet fraction is treated in an anaerobic digester. The RDF is further separated into a cellulosic fraction and a non-cellulosic fraction. The cellulosic fraction is treated by pyrolysis and produces a pyrolysis liquid. The pyrolysis liquid is added to the anaerobic digester.
