Some embodiments are directed to a process for forming products from animal waste (e.g., poultry litter). The products may include a controlled release fertilizer and renewable natural gas. The process may include providing a feedstock comprising greater than about 80 percent poultry waste and a moisture content of about 25 percent. The feedstock may be diluted to form a slurry having a moisture content of about 90%. The slurry may be mechanically refined to reduce the particle size distribution and the average particle size of the slurry. The slurry may be anaerobically digested to produce biogas and a digestate. The biogas may be converted to renewable natural gas, and the digestate may be converted to a controlled release fertilizer. Additionally, some embodiments are directed to methods of reducing nitrogen emission from soil amendments. Some embodiments are directed to reducing nitrogen emissions sufficient to produce emissions offset credits.

This specification describes systems and methods for treating wastewater, for example digestate. The wastewater is separated into a liquid fraction and a solid fraction. The solid fraction of the wastewater is composted. The liquid fraction of the wastewater can be treated, which may result in further by-products. Optionally, at least some of the liquid fraction may be reused in the process. The by-products produced in treating the liquid fraction and/or additional organic solid waste, for example green waste, brought into the treatment facility can be added to the compost. The compost breaks down through aerobic and/or anaerobic digestion processes. Thermophilic conditions may develop in composting piles and increase the rate of evaporation of excess water. When sufficiently dry, the compost may be used as a fertilizer or soil enhancement product.

The invention is a system and method for transforming food waste into a commercial cleaning product. The system is containable in an enclosed facility and installable in urban environments. Food waste is sorted and ground into uniformly sized particles, heated to an acceleration temperature, inoculated with an inoculant including lactic acid bacteria, which is mixed into the ground waste. The waste then undergoes sedentary fermentation for times as short as 24 hours or less. The fermented waste is separated into liquids and solids, and liquids are further separated into at least one distillation stream. Solids are dried to obtain a second distillation stream.

The invention relates to a method for recovering phosphorus from sludge in sewage plants, wherein: the sludge is pre-acidified under anaerobic process conditions and the pH value is then increased to a pH value <7 by adding at least one alkaline calcium-containing chemical; brushite crystals are formed by calcium ions of the chemical and are precipitated, and deposited brushite crystals are removed; and the phosphorus-reduced sludge is then supplied to a digestion process.

Various waste fractions from meat, gravy, and animal feed industries, that are difficult to recycle, as well as wastes, for example, from fishing and fish processing, are often challenging to separate for further processing into products. The hygienic and otherwise safe and economical utilization of these, consistent with ecologically sustainable development, requires the development of new methods. According to the method and apparatus of this invention, with the help of microbes and their enzymes, for example, bone and tissue waste, as well as protein, fat material or materials containing blood matte, that have been separated during meat processing, can be fractioned into new raw materials. Gained products can be, for example, energy fractions and gases, waxes and various organic fertilizers and soil improvement substances.
