A waste treatment system comprises: a first hydrothermal treatment device for performing hydrothermal treatment of waste; a first solid-liquid separation device for separating a first reactant of the first hydrothermal treatment device into a solid and a liquid or slurry; a second hydrothermal treatment device for performing hydrothermal treatment of the solid of the first reactant; a second solid-liquid separation device for separating a second reactant of the second hydrothermal treatment device into a solid and a liquid or slurry; and a fermentation device for fermenting the liquid or the slurry of the first reactant and the liquid or the slurry of the second reactant.

The invention provides a recycling method of polyester cotton blended fabrics, which includes the following steps. First, the polyester cotton blend fabric is cuts into fragments. Afterwards, the fragments are placed in a reactor, a mixed aqueous solution of an acidic compound and a metal catalyst is added, a temperature is raised to 110 C. to 160 C., and a reaction is carried out for 1 to 6 hours to cleave the cotton fibers. Next, filter and separate to obtain cotton powders and a polyester fiber.

The present invention provides systems and methods for the recycling of animal bedding and the disposal or reuse of manure, feces, urine or expectorant resulting from recycling animal bedding. The present invention provides systems and methods for the disposal of materials related to the recycling or repurposing of stall residual waste and/or soiled animal bedding which is environmentally conscious to aquifers, and further limiting off gassing of enteric methane and other gasses. Use of such methods create a healthier recycled bedding than existing new bedding materials. The reusable and clean animal bedding provides for a healthy, hygienic, sanitary and enhanced stall environment. The present invention further provides methods for infusing additives, enhancements or amendments to recycled animal bedding which promote the health and safety of the animals using the recycled animal bedding (or the humans in contact with the animal bedding or animals) and/or the barn environment.

A horizontal reactor equipped with a front cover and including a circular cylindrical rotating cage having multiple openings and rotated about a horizontal axis by a motor, a single horizontal rotary shaft mechanically connecting the rotating cage to the motor and extending towards the outside from the distal face of the housing, at least one bearing provided around the rotary shaft to hold it and guide it, and to support the weight of the rotating cage in cantilever, at least one removable basket having multiple openings and intended to be able to be introduced inside the rotating cage and to be removed through an open circular face of the rotating cage provided opposite the cover.

A method for recycling polyester fabrics with use of an ionic liquid catalyst is provided, which includes: providing a recycled polyester fabric; and using a chemical de-polymerization liquid to chemically de-polymerize the recycled polyester fabric and form a de-polymerization product that includes bis-2-hydroxylethyl terephthalate (BHET). The chemical de-polymerization liquid is used to chemically de-polymerize the recycled polyester fabric in an environment where a de-polymerization catalyst exists, and the de-polymerization catalyst is the ionic liquid catalyst in a solid state.

A system for producing one or more high-density fragments comprising carbon from an organic material and methods for making and using the same. The system can include increasing a density of the organic material to form the high-density fragments and can determine a critical submersion depth for the high-density fragments. The critical submersion depth can comprise a depth below a water surface of a body of water at which the high-density fragments must be submerged such that a density of the high-density fragments is greater than the density of the body of water. The system can submerge the high-density fragments in the body of water at a predetermined injection depth that is below the critical submersion depth so that the high-density fragments will sink to a floor of the body of water. Thereby, the system advantageously can produce a product comprising a mixture of carbon and water.

A process for transforming a stream of MSW material into feedstock for an anaerobic digester and the resulting generation of biogas and other useful products includes the removal of one or more selected chlorine containing components and the retaining of substantially all paper components. At least 70% by mass of the incoming stream of MSW material is hydrolyzed and subsequently directed to the anaerobic digester.

A method for sequestering carbon in a body of water (28), the method consisting of receiving a mass (52) of carbon-containing matter, the mass having an initial average density that is less dense than the water, and submerging the mass in the body of water to a depth (66) at which the mass becomes denser than the water due to compression of the mass by water pressure. When the mass has become denser than the water, the method includes releasing the mass to sink in the body of water. The mass of carbon-containing matter may be in the form of loose matter or bales.

Present disclosure provides a system to process textile waste. Said system comprises a dissolution chamber that receives the textile waste, wherein said dissolution chamber stores a first organic solvent to dissolve a polyester fraction of the received textile material, producing a suspension of undissolved cotton in said first organic solvent. A first filtering unit receives said suspension and generates a polyester liquid stream and a solid cotton fraction. A precipitation unit receives said polyester liquid stream and a second organic solvent to generate a precipitated polyester dispersion. A second filter separates solid polyester from a cocktail based on said first and second organic solvents. A first solvent recovery unit separates said organic solvents, returning said first organic solvent to said dissolution chamber and said second organic solvent to said precipitation unit. A bioreactor enables enzymatic treatment of said solid cotton fraction.

A method may include determining a first dry mass flow rate of a wet paper material stream based on a first amount of contaminants, a first moisture content, and a first wet mass flow rate of the wet paper material stream, determining a second dry mass flow rate of a wet plastic material stream based on a second amount of contaminants, a second moisture content, and a second wet mass flow rate of the wet plastic material stream, calculating, using the first dry mass flow rate and the second dry mass flow rate, a paper/plastic ratio of a combined stream of the paper material stream and the plastic material stream, and adjusting, a flow rate of paper into the paper material stream and a flow rate of plastic into the plastic material stream such that the calculated paper/plastic ratio of the combined stream equals a target paper/plastic ratio.
