A method of capturing and disposing of fats, oil and/or grease (FOG) is disclosed. The method includes providing a vacuum truck to a user, wherein the vacuum truck has a tank with (1) a vacuum hose; (2) an inlet to the tank connected directly to the hose; (3) an outlet from the tank; (4) and one or more mixing components. The method also calls for positioning an absorbent material within the tank that is capable of absorbing a quantity of FOG. Next, FOG is vacuumed from a grease trap via the hose and mixed with the absorbent material to create a biofuel. Finally, the biofuel is discharged from the outlet of the tank into a containment device at a burn facility and subsequently burned. Alternatively, the absorbent material may be contained within a containment device at the burn facility and mixed with the FOG at the facility before being burned.

Systems and methods for producing engineered fuels from solid waste material are described herein. In some embodiments, a method includes receiving a waste stream at a multi-material processing platform and separating the waste stream to remove non-processable waste and marketable recyclables. The method further includes conveying processable materials to a material classification system and incorporating additives to produce an engineered fuel from the constituents of the waste stream.

A carpet pellet machine and method are disclosed. One embodiment provides an apparatus comprising a compressor to receive fibrous material and compress the fibrous material, a mold pipe system to receive compressed fibrous material from the compressor, wherein the compressor is configured to press the fibrous material through the mold pipe system, and a heat chamber to heat the fibrous material within the mold pipe system and create an encapsulation layer on the fibrous material.

A method for producing a briquetted solid fuel includes pulverizing a low-rank coal. The pulverized low-rank coal is mixed with a solvent oil to give a slurry. The slurry is heated and dewatered to give a dewatered slurry. The solvent oil is separated from the dewatered slurry to give a cake. The cake is heated to further separate the solvent oil from the cake to thereby give a refined coal in powder form. The refined coal is combined with a property-controlling coal in powder form having, as properties, a loose bulk density of 0.6 kg/L or more and an angle of repose of 40 or less, to give a briquetting feedstock containing the property-controlling coal in an amount of 5 to 70 mass percent based on the total mass of the briquetting feedstock. The briquetting feedstock is briquetted under pressure to give the briquetted solid fuel in briquette form.

A fertilizer/soil conditioner or a fuel source material is formed by processing animal waste by-products through the use of a rotary biomass dryer system. The animal waste by-product includes without limitation manure obtained from cattle or swine; feed lot bedding, poultry litter, a digestate of animal waste by-products obtained from an anaerobic digester, municipal waste, waste meat renderings, waste meat, or a mixture thereof. The processed material may comprise a higher amount of ash and a lower amount of volatile material than the animal waste by-product. The processed material may be stored as a powder or processed into pellets, logs, pucks, briquettes or another convenient shape form.
