Methods and systems are provided for processing PFAS-contaminated waste via thermomechanochemical (TMC) processing. In one example, a system may include a TMC processing chamber including a milling system and coupled to a heating system, the heating system configured to co-operate with the milling system to process the waste material. A plurality of containers including the waste material in one or more of a liquid-solid state, a semi-wet or slurry solid state, and a dry solid state are coupled to the TMC chamber.

Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input put material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis. The resultant output of oil and gas can either be stored or fed into a boiler unit to be used as a fuel to produce hot water, or used to run an electricity generating unit to power the dwelling in question or for supply to a feed-in tariff. Thus, a domestic dwelling includes a thermal treatment unit for processing waste produced in the dwelling, an output of the thermal treatment unit being combusted for producing an energy output for the dwelling. A suitable pyrolysis chamber is disclosed.

A method for deep desiliconization of coal ash and recovery of silicon resources includes: ball-milling and drying decarburized coal ash; adding calcium oxide into a salt to obtain a mixture, and heating the mixture to a molten state under an inert atmosphere to obtain a molten salt, a molar ratio of the calcium oxide to the salt ranging from 0.5% to 18%; placing the ball-milled and dried coal ash into the molten salt, performing reaction under an atmospheric pressure, separating a reaction product from the molten salt, cooling the separated reaction product under an inert atmosphere, washing the cooled reaction product and drying the washed reaction product to obtain desiliconized coal ash; and cooling the molten salt under an inert atmosphere, washing the cooled salt and filtering the washed salt to recover calcium silicate and a filtrate.

Provided is a method which allows, for example, suppression of foaming in the purification step such as distillation and continuous operation, as well as direct treatment of a waste liquid (can liquid) without having to subject the same to an extra purification treatment by removing the microorganisms, nitrogen compounds, and phosphorous compounds at once from an organic substance-containing liquid obtained from microbial fermentation. Also disclosed is a method for producing an organic substance, comprising a microbial fermentation step, a separation step, a liquefaction step, and a second purification step, wherein the concentration of the nitrogen compound in the second can liquid is 0 to 150 ppm based on the total mass of the second can liquid, and the concentration of the phosphorous compound in the second can liquid is 0 to 5 ppm based on the total mass of the second can liquid.

Provided is a sorting method for valuable resources, including a thermal treatment step of thermally treating a target containing valuable resources, to melt aluminum and separate a melt, a pulverizing step of pulverizing a thermally treated product remaining after the melt is separated, to obtain a pulverized product, a magnetic sorting step of sorting the valuable resources from the pulverized product by a magnetic force, and a wind force sorting step of sorting one valuable resource from another valuable resource in the valuable resources by a wind force.

A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.

Embodiments disclosed herein provide a bucket assembly and method of use thereof. The bucket assembly is a relatively lightweight and removable apparatus that can fracture cut, paddle, and heat contents contained therein. The bucket assembly can include a housing that has a curved metal plate and blade array attached thereto. A cut and paddle assembly can rotate within the housing and interface with the blade array to fracture cut contents contained therein. The cut and paddle assembly is also operative to mix the contents to ensure full dispersal within the housing. A flexible heater array is attached to and operative to heat the curved metal plate. The combination of the fracture cutting, paddling, and heating can convert organic matter to a ground and selectively desiccated product.
