A method for producing an amino acid liquid fertilizer from waste feathers includes: acquiring an enzymatic hydrolysate by performing enzymolysis on feather powder with a complex enzyme; adding acid protease to the enzymatic hydrolysate for enzymolysis; and acquiring the amino acid liquid fertilizer by performing enzyme inactivation on a filtrate acquired by performing filtering after enzymolysis is completed, wherein the complex enzyme includes keratinase and amino acid peptidase. By adopting this method, the enzymolysis rate of the feathers reaches 80% or above and the prepared amino acid liquid fertilizer contains various kinds of amino acids (17 amino acids); and the content of the amino acid can reach 10.12% (by mass fraction) or above and the content of small peptide reaches 9.39% (by mass fraction), which reach the Chinese standard of the amino acid liquid fertilizers without concentration. Thus, the environmental-friendly amino acid liquid fertilizer can be prepared.

A system for recovering fat, oil and grease (FOG) from wastewater has multiple annular flotation zones in a concentric configuration surrounding a central column to create progressively increasing surface areas for FOG and solid particles flotation. Each flotation zone may be equipped with an independent pressurized micro air and/or ozone bubbles distribution system. The FOG is recovered in the first flotation zone without chemical additions. Coagulant and flocculant may be added in the second flotation zone to maximize removals of biochemical oxygen demand (BOD), total suspended solids (TSS), and colloidal particulates and produce clear effluent. Magnesium chloride is added in the third flotation zone to remove phosphorus and to form struvite particulates that can be used as fertilizer. Since both organic loading and solid loading in the treated effluent are significantly reduced, poultry processing plants can more easily meet wastewater treatment plant discharge limits and avoid surcharges.

The present disclosure refers to a keratin-based substrate, comprising a keratin derivative and natural biopolymer, where the keratin derivative and natural biopolymer are crosslinked. The present disclosure also refers to a method of forming a keratin-based substrate, comprising (i) mixing a solution of keratin derivative with a solution of natural biopolymer; and (ii) drying the resulting solution of step (i) to obtain the keratin-based substrate. The present disclosure further relates to the use of the substrate as a plant growth medium or hydroponic support medium. In a preferred embodiment, a substrate comprising keratin intermediate filament protein and cellulose nanofibers is provided.

The present invention relates to a carcass treatment system 1. Such a carcass treatment system 1 ferments and decomposes carcasses by hyperthermophile of 85 to 110° C. and aerobic conditions, and comprises a mobile fermentation process unit 3 for transferring to an onset site of disease and treating the livestock carcass by hyperthermophile; or a burial fermentation process unit 5 for excavating a burial site 6 near the outbreak site of disease and treating the livestock carcass by hyperthermophile; a base treatment unit 7 for secondarily processing the livestock carcass treated primarily by the mobile fermentation process unit 3 or the burial fermentation process unit 5 with hyperthermophile, wherein the primary treatment is performed by treating with hyperthermophile at fermentation temperature of 85 to 110° C. for 8-15 days to decompose flesh of the carcass, and the secondary treatment is performed by treating with hyperthermophile for 2-4 weeks.
