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.

A manufacturing method for a carbon heat source comprises: a step A1 of forming a first groove in a state where the plurality of carbon members are aligned in one line; a step A2 of changing, subsequent to the step A1 being performed, an orientation of the plurality of carbon members so that the first groove formed in the plurality of carbon members crosses relative to the first predetermined direction in a state where the plurality of carbon members are aligned in one line; and a step A3 of forming, subsequent to the step A2 being performed, a second groove in a state where the plurality of carbon members are aligned in one line.

The invention provides methods to efficiently reduce the water concentration of raw solid fuels, including low rank coals such as brown coal, lignite, subbituminous coal, and other carbonaceous solids. Efficiently drying these materials at low temperatures significantly reduces greenhouse gas emissions and allows the production of low-rank coals for gasification and liquifaction.

A method of capturing and disposing of fats, oil and/or grease (FOG) is disclosed. The method includes: providing a porous container formed of a porous fabric, wherein the porous container is filled with an absorbent material capable of absorbing a quantity of the fats, oil, and/or grease through the porous fabric of the porous container; placing the porous container and the absorbent material contained therein in a grease trap; allowing the grease trap to fill up with water and a mixture of fats, oil, and/or grease; removing the fats, oil, and/or grease from the grease trap after a pre-determined period of time, while the water remains in the grease trap; and transporting the fats, oil, and/or grease. The fats, oil, and/or grease may be removed from the grease trap and transported with a vacuum truck.

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.
