A pyrolysis method and system are provided that may utilize a recycled plastic feedstock that comprises various types of waste plastics or a feedstock that comprises various types of waste plastics and at least one crude post-industrial liquid waste. The disclosed pyrolysis method and system may be configured to convert various types of waste plastics, including post-customer and post-industrial wastes, and/or crude post-industrial liquid wastes into useful pyrolysis oils.

The present invention provides a system for thermal remediation and/or the processing of a feed materials like contaminated materials, waste polymeric materials, waste paper products, waste wood and biomass. The system comprises at least one thermal screw conveyor provided in a housing under pressure, a first plug screw conveyor in a housing in communication with an inlet of thermal screw conveyor housing and a second plug screw conveyor in a housing in communication with an outlet of thermal screw conveyor housing. The thermal housing is configured to heat the feed material to form one or more vaporized products and a solid residue, wherein one or more vaporized products are removed through the one or more vapor ports provided in the pressure housing, and the solid residue is discharged from an outlet of the second seal-housing.

A recycling and fabrication appliance is provided. The recycling and fabrication appliance is generally configured to convert solid waste, solid materials and/or solid objects into a usable or reusable product. The recycling and fabrication appliance generally comprises a single unit with one or more inputs and one or more outputs. The unit may be a cuboid, or may be any appropriate shape, and may specifically be configured to recycle or repurpose solid waste, solid materials or solid objects into a reusable form at or near the point of consumption or disposal, such as a household or office. The components of the recycling and fabrication appliance may be housed within the unit and may enable the recycling and fabrication appliance to receive various solid waste pieces as an input and to produce a single usable output, referred to herein as a output object.

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.

A system for processing rubber material pre-heats the material and then applies microwave energy to process the system The system comprising a rubber material receiver for accepting the rubber material which passes the material to a pre-heating unit adapted for the rubber material passing through comprising a plurality of heating elements that heat the rubber material to between about 100 to about 350 C in an oxygen depleted atmosphere. Once pre-heated, the material is conveyed to a microwave unit adapted for receiving the pre-heated rubber material comprising microwave magnetrons, which radiate the pre-heated rubber material and external heat sources in an oxygen depleted environment until the pre-heated rubber is substantially reduced to a carbonaceous material having a volatile content of below 5% and more preferably below 2%. After being processed by microwave energy, the processed material exits on a cooling conveyor that receives processed rubber material from the microwave unit and cools the material in an oxygen depleted environment. One or more conveyors are used to transport the rubber material from the rubber material receiver into and through the pre-heating unit and into and through the microwave unit to the cooling conveyor.

A method for producing asphalt comprising a heat treatment step, wherein the rubber granules deriving from an end-of-life tyre granulation process are subjected to a temperature of between 80 and 300 C., for a period of time necessary in order to obtain rubber granules with a density of between 1.0 and 1.5 g/cm.sup.3; and a mixing step wherein the rubber granules from the heat treatment step are mixed with stone aggregate and bitumen in order to obtain asphalt.

Provided herein is a process for producing furfural from lignocellulosic biomass or an extract thereof, such as an extract rich in saccharides, using solid zinc sulfate-rich catalysts to catalyse conversion to furfural. Also provided herein are zinc sulfate-rich catalysts, and processes for producing zinc sulfate and zinc sulfate-rich catalysts from tyre char.

This invention details a method and device for recycling polymeric, composite, and industrial rubber waste. It involves a bath of liquid-metal coolant, made by melting metals like lead, bismuth, zinc, aluminum, and copper. This coolant is heated to 50-150? C. above its melting point. A layer of melted salts of alkaline and alkaline-earth metals is formed on the coolant's surface, topped by a purifying layer of melted active alkaline or alkaline-earth metals. Waste is pre-loaded into perforated-wall containers with horizontal partitions and submerged in the coolant bath, then removed after processing. The device includes guide rails, an internal space with a hearth, side walls, roof, inlet and outlet sluices, and a reaction chamber. This process improves desulphurization and dichlorination of pyrolysis products, yielding a solid carbon-containing residue.

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.

A system for conducting high-temperature thermolysis of waste tires and rubber products are proposed. By using the system, the waste tires and rubber products may be recycled jointly and efficiently to produce hard carbon, a synthesis gas, and a thermolysis liquid, which may be used profitably for various purposes.
