A device for wholly treating urban and rural mixed household refuse at low temperature on site is provided. The device includes a vibration sieving and crushing system, a magnetic separator, conveyor belts, a magnetic pulse mineralization reactor and a tail gas purifying device. By using the device, urban and rural mixed household refuse is continuously fed; the mixed household refuse is sieved by the vibrating sieve according to viscosity, weight and size; nonferrous metal is sieved through a magnetic field; and organic substances are conveyed to the magnetic pulse mineralization mixed household refuse treatment device for terminal treatment. So, efficient reduction and harmlessness of the organic substances in the mixed household refuse are realized, and the pollution of organic wastes on the environment is effectively eliminated.

The present invention makes public a method and an apparatus for the revalorization of various organic waste, by means of physics and mechanics. The bubbles are produced and injected into the mixture in the sealed tank under depressure, then establish the movement of toric rotation in the vertical direction. The high-speed movement bubble carrying focused energy vigorously collide into the mixture, thus showing the Rheo-fluidizing effect (Shear thinning), decreasing the viscosity and depolymerizing long-chain molecules. This achieves active bacteria killing, separation, concentration and de-emulsification; the solution's advantage is applied to various organic residue, with short and efficient processing cycles, without producing unpleasant odors and is non-polluting, chemical free, at low temperature, low energy consumption, no GHG emission, preserving the microorganisms and nutrients of organic matter, and separating the pollutants such as the oils and fats. The usage of the output is unlimited, the invention is helpful to restore the ecosystem.

The present invention provides a method and a system for processing of waste by anaerobic digestion, said method comprising pre-treatment of a first biological waste stream by thermal hydrolysis and processing of a solid fraction by pyrolysis prior to anaerobic digestion.

The present invention allows for efficient utilization of the energy available in biological waste sources. The method provides an energy efficient method for processing of biological waste having a high degree of recovery of the energy stored in the waste material, wherein the flow of material may be dynamically adjusted to e.g. achieve end products in preferred ratios.

The invention related to an apparatus for recycling of lignocellulosic fibres from a fibreboard comprising compressed lignocellulosic fibres bonded together by a binding agent. The apparatus comprises a transport device arranged within a closed housing, wherein the housing is arranged for steaming pieces of the fibreboard at super-atmospheric pressure to decompress and release the lignocellulosic fibres by hydrating them, as well as hydrolysing the binding agent, and the transport device is arranged for transporting the fibreboard pieces, upon being steamed, from an inlet of the housing, at which the fibreboard pieces are fed to the housing, to an outlet of the housing, at which steamed portions comprising released lignocellulosic fibres exit the housing. Further, the apparatus comprises a steam generator in communication with the housing, whereby the fibreboard pieces may be steamed at super-atmospheric pressure in the housing to provide the steamed portions comprising released lignocellulosic fibres, an inlet pressure lock configured to receive the fibreboard pieces at atmospheric pressure and to deliver them to the housing, via the inlet, at super-atmospheric pressure, and an outlet pressure lock configured to receive steamed portions comprising released lignocellulosic fibres via the outlet and ejecting recycled lignocellulosic fibres during a sudden expansion of super-atmospheric pressure.

The present invention relates to a method for degradation of a plastic-containing waste further comprising cellulosic, plant and/or animal waste, the method comprising mixing the plastic-containing waste with a composition comprising bacteria in the presence of air wherein the plastic containing waste is filled to a predetermined level in a digesting apparatus comprising of an elongated tank having one or more rotating mixing shafts provided with radially extending agitating blades fixed to the shafts, wherein the plastic containing waste has a surface-to-volume ratio of at least 1.1 when the digesting apparatus is filled to the predetermined level, whereby the surface area is the surface area in m.sup.2 of the filled plastic containing waste to air interface, and the volume is the volume of the plastic containing waste in m.sup.3.

Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.

Clean, safe, and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various waste sources into a Clean Fuel Gas, Char, and Biochar are provided. The process further converts the Clean Fuel Gas into both a purified hydrogen source for green ammonia production and natural gas. The methods process waste sources to effectively separate, neutralize and/or destroy halogens and other hazardous components to provide a Clean Fuel Gas, Char and/or Biochar, which can then further be processed to extract and purify hydrogen for green ammonia production from the Clean Fuel Gas and thereby provide natural gas. The Clean Fuel Gas is a natural and renewable natural gas as it is continually produced and further available for use to provide energy and new products.

Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.

A panel and a method for manufacturing thereof where the panel includes a first layer comprising a first blend of paper fragments and plastic fragments; a second layer comprising a second blend of paper fragments and plastic fragments, wherein the paper fragments and plastic fragments of the second blend are coated with an adhesive; and a third layer comprising the first blend of paper fragments and plastic fragments, wherein the second layer is disposed between the first layer and the third layer, and wherein the first layer, the second layer, and the third layer are combined to form the panel using heat and pressure. In another embodiment, the paper fragments and plastic fragments of the first blend, not the second blend, are coated with an adhesive.

A self-contained material separator system utilizing a vacuum and blower system, a separator assembly, and a collection assembly to separate and process waste material generated from material handling and processing devices.
