Abstract: The invention is a process for treatment of brown grease, where the brown grease comprises water, food solids and free-oil. This process starts with the collection of the brown grease into a container. The brown grease's pH is adjusted with a chemical treatment to produce an adjusted brown grease phase. To the adjusted brown grease phase an anionic copolymer treatment mixture is added along with a cationic copolymer to form a reaction mixture. The reaction mixture reacts for a period of time, and during this time wastewater is discharged from the reaction mixture to produce resulting solids. The resulting solids are then transferred from the container for disposal or are processed further into a fuel or soil additive.

Abstract: Processes and apparatus produce economically feasible biodiesel without subsidies. Toward that end, integrated small plants process materials containing lipids with anhydrous bioethanol as solvent and reactant, and sulfuric acid and potassium hydroxide mainly as catalysts to produce up to 3 million gallons of biodiesel per plant per year.

The raw material may include a wide variety of non-edible solid matter that contains lipids, which normally have from 0.5% to 80% by weight of free fatty acids in total oils. Multiple apparatus makes this process feasible. In addition to not competing with food production, since they supply fertilizer for small scale farmers, the processes and apparatus allow sustainable liquid fuel production.

Abstract: Systems and methods for automated, rapid composting are disclosed. An air-tight housing prevents odors from leaking out. The housing is thermally insulated to enable the compost to achieve sufficient temperatures for rapid composting. A chambered system, generally including an optional hopper, a reactor, and a cure tray, physically shields odorous material from the external environment. A mixing wand mechanically mixes and/or breaks up the compost material and enhances air flow therethrough. A drip tray segregates liquid byproducts from the solid compost material. An air pump draws in air, while a carbon filter may absorb odors before returning the air to the external environment. A motor provides mixing, and facilitates opening and closing of the two trap doors separating the chambers. An electronic controller automates the composting process while allowing certain settings to be adjusted.

Abstract: A value-added granulated organic fertilizer produced from poultry litter and biosolids using agglomeration techniques with a pin mixer. The granulated organic fertilizer includes granules biosolids, a nitrification inhibitor, such as dicyandiamide, and a binding agent, such as lignosulfonate, urea formaldehyde, or water. The nitrogen concentration of the granulated organic fertilizer is increased by being fortified with urea. The poultry litter and biosolids formulated into the granulated organic fertilizer aid in flowability, storage, and spreading, while value-added plant nutrient ingredients provide an environmentally safer fertilizer than fresh poultry litter, municipal biosolids and/or many commercially available products commonly used in urban and agricultural systems. The binding agents change the fertilizer granule water soluble phosphorus and nitrogen concentrations and reduce fines and dust.
