A process of fiberglass recycling, such as for windmill blades or other feedstock having a fiberglass component. An example of the process includes cutting a feedstock having a fiberglass component. After cutting the feedstock, it is fed into a controlled kiln for pyrolyzing. Pyrolysis is at a temperature of about 550-650 degrees Celsius to completely remove all resins, epoxies, and other non-fiberglass components from the feedstock to produce a fiberglass end-product.

The invention relates to a process for the production of a composite material from textile waste and polyethylene film waste, characterized in that it comprises the following steps: a) comminuting the textile waste into the fraction up to 15 mm in size, b) comminuting the polyethylene film into the fraction up to 15 mm in size, c) separating metal parts from the comminuted textiles, d) separating metal parts and unwanted plastics from the comminuted film, e) further comminuting the textiles into the fraction up to 5 mm in size, f) mixing the comminuted textiles with the comminuted film, said textiles constituting 10-50% of the mixture, g) plasticizing, homogenizing and extruding the obtained mixture in an extruder at the temperature of 170-240° C. and under the pressure of 8-15 MPa.

A method includes producing recycled products from a plurality of used absorbent articles, each including a top sheet, a back sheet and an absorbent body including absorbent body materials, by recovering a plurality of structural members from the plurality of used absorbent articles. At least one of the top sheet and the back sheet includes a film. The method includes: separating the plurality of used absorbent articles into a plurality of the films and the absorbent body materials; sorting the plurality of films into a plurality of types of recyclable films according to the filler contents of the plurality of films; and forming a plurality of types of recycled resin pellets from the plurality of types of recyclable films.

An embodiment provides a method for recycling tires, including: injecting, using a pump, a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material; within the dissociating system, creating a rubber material mixture, by: injecting a supercritical fluid to be mixed with the rubber material; heating, using a heat source, the rubber material mixture; and atomizing the rubber material mixture; and sending the resulting atomized rubber material mixture to a separating system to separate the rubber material mixture into different components. Other aspects are described and claimed.

A waste management system, primarily intended to be for waste floating in water, though it can also be used on land. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is cryogenically frozen using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon and water may be recycled. The carbon may be used as fuel by the ship. Water may also be used by the ship or returned to the ocean in a non-toxic condition.

A method of recovering structural members from a used absorbent article comprising a front sheet, a back sheet and an absorbent body between the front sheet and the back sheet, wherein at least one of the front sheet and the back sheet includes a film, and wherein the absorbent body includes an absorbent body material, may include swelling the used absorbent article with water, applying a physical shock to and disintegrating the swelled used absorbent article into at least the film and the absorbent body material, and separating the film and the absorbent body material.

Machine for recycling tyres by recovering the tyre tread rubber using waterjets. The machine comprises a loading unit for loading a tread, a processing unit, the processing unit comprising a framework comprising a preprocessing zone, a processing zone and a postprocessing design. The preprocessing zone drives a cut tread towards the processing zone. The processing zone comprises a processing module designed to direct a waterjet onto the recovered tread. The preprocessing zone comprises motorized guide rollers and presence sensors arranged in such a way as to allow a second tread to catch up with a first tread in such a way as to reduce, to the point of closing up, the space between two treads.

A method for manufacturing a carbon fiber is provided which involves: (1) immersing a carbon fiber composite material (CFC) in an acidic aqueous solution to elute at least a part of a resin component of the CFC, to thereby obtain a substantially fibrous product; and (2) immersing the substantially fibrous product obtained in step (1) in an alkaline aqueous solution to elute at least a part of a resin component of the substantially fibrous product, to thereby obtain a fibrous product. A method for manufacturing a carbon fiber reinforced resin composition is provided which involves manufacturing a carbon fiber by the above method and manufacturing a carbon fiber reinforced resin composition using the resulting carbon fiber. Using these methods, it is possible to recover and recycle a carbon fiber from a carbon fiber composite material (CFC) at a low cost without deteriorating the carbon fiber.
