The present invention relates to a fertiliser and/or soil improver, for use in enhancing the growth of plants, comprising keratin, preferably obtained from wool. Also described is a method of enhancing the growth of plants using a fertiliser and/or soil improver comprising keratin.

Disclosed are methods and systems for the conversion of poultry waste into useful products. Some embodiments are directed to a process for forming a product solution from poultry waste. The process includes providing a feedstock that contains greater than 60 percent poultry waste, and anaerobically digesting the feedstock to produce a digestate that has a solids content of about 5% to about 15% by weight. The process also includes separating and classifying the digestate into multiple high solids fractions and a first filtrate. The process also includes adding the high solids fractions to an acid solution to form a slurry that is then separated and classified into multiple second solids fractions and a second filtrate. The process also includes clarifying the first and second filtrates to produce a first and a second centrate. The process also includes mixing the first centrate with the second centrate to form the product solution.

The present disclosure relates to the field of commercial scale production and processing of pharmaceutical liquid or solid compositions derived from insects, wherein the compositions include a purified recombinant protein, vaccine, antibody, peptide, or chemical, and where the virus includes a recombinant baculovirus. Systems and methods to produce the insects and a purified insect-derived recombinant protein, vaccine, antibody, peptide, insecticide, fungicide, or chemical within a bioreactor are also described.

Today's funeral practices are unsustainable, toxic, and polluting. Both cremation and the manufacture and transport of caskets, grave liners, and headstones emit greenhouse gas emissions into the atmosphere. In fact, the very last thing that most of us will do on this earth is poison it. As a response, a system and method called recomposition that gently and naturally returns humans to the earth after death.

A product, system and method for an improved plant fertilizer made from harvested skimmate from a reservoir filed with a reduced sodium, artificial ocean water solution and live fish that produce fish excrement (reclaimed as skimmate). The skimmate contains a reduced concentration of sodium as a result of being harvested from a reduced sodium aquatic solution. The harvested skimmate is mixed with one or more additives to produce an improved fertilizer that may be certified as organic.

A digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.

A rural bulk organic waste pollutant source comprehensive treatment system including a solid high-temperature aerobic fermentation reactor, a liquid high-temperature aerobic fermentation reactor and a multifunctional boiler is provided. A rural bulk organic waste pollutant source comprehensive treatment method. For excretion waste of a livestock farm adopting the technology of manure cleaning by urine submerging, a solid-liquid separation is firstly performed thereto, wherein solid is conveyed to the solid high-temperature aerobic fermentation reactor and fermented to produce solid organic fertilizers, and liquid is conveyed to the liquid high-temperature aerobic fermentation reactor and fermented to produce liquid organic fertilizers. For dry collection manure of a livestock and poultry farm, carbon-containing auxiliary materials, residues left after dead animals and household waste being incinerated by the multifunctional boiler, and ash generated by straw burning are added thereto, and then the mixture is conveyed to the solid high-temperature aerobic fermentation reactor and fermented to produce solid organic fertilizers. Exhaust fume and hot water produced by the multifunctional boiler pass through the solid high-temperature aerobic fermentation reactor and the liquid high-temperature aerobic fermentation reactor to heat the reactors and keep the reactors warm.
