The present invention relates to a method for producing a recycled insulating material from insulating wool, said method comprising the steps of: comminuting insulating wool to give a first intermediate comprising fibre balls; adding binder to the first intermediate to give a second intermediate; hot-pressing the second intermediate into the desired shape, to give a third intermediate; and curing the third intermediate to give the recycled insulating material. The present invention further relates to a method for recycling insulating wool, an apparatus for processing insulating wool, and a fibre-reinforced foam. The invention additionally embraces a fire-resistant wood-based material and a method for producing it.

Biological waste such as food, organic or other biologically-derived waste is converted into shelf-stable and health-safe invertebrate feed. The method for converting includes pre-treating waste by fragmenting, reducing microbial contaminants, optionally amending with components that optimize fermentation, inoculating with microorganisms and mixing. Fermentation takes place in a bioreactor and produces fermentation leachate and solid fermentate. In the post-treatment steps, the solid fermentate is separated from the fermentation leachate. The solid fermentate is ground, dewatered and milled. The solid fermentate can be used as an invertebrate feed with or without further processing.

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.

Plastic waste is shredded and formed to a desired shape and held together using a binder and/or heat, etc. The resulting composite material may be useful for building and/or furniture and/or flooring, etc. (similar to wood composite board). In some embodiments, the board is highly water resistant. Optionally, the board is made of layers. For example, an inner layer has reduced density and/or an outer layer may have decreased particle size and/or increased fiber content.

A shredder dust treatment method is provided wherein non-metal dust which is further pulverized into a small particle size in a pulverizing step S10 through a crushing step S1 of crushing wastes such as waste automobiles, waste home appliances, and waste office furniture into a predetermined size, an iron component separation and collection step S3 of separating and collecting an iron component, a non-ferrous component separation and collection step S4 of separating and collecting a non-ferrous component, a metal component separation and collection step S5 of sorting a metal component, wind power sorting steps S2, S6, S8, and S9 of sorting floating fibrous dust and a settled crushed material by wind power, and a shredding step S7 of shredding the settled crushed material into a predetermined size is separated into metal scraps such as copper, aluminum, and iron, fibrous dust, and particulate dust in a separating step S11.

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 method for providing long term carbon sequestration and reducing an individual's personal carbon footprint comprises: growing, harvesting, drying and grinding a plurality of weeds, then pressing the ground weeds into hollow block shells for manufacturing blocks therefrom. The hollow block shells could be made a recycled plastic, a plant based plastic, bamboo, a reclaimed wood fiber, ground up nut shells and/or a fungus material. The method, and the blocks manufactured thereby could conceivably impact total atmospheric carbon dioxide levels as a CO.sub.2 Net Negative Emissions (NNE) technology.
