Abstract: Provided is a method of processing a plastic, the method comprising introducing a plastic slurry having particles with a particle size of less than 20 mm into a macerator, the macerator comprising an inlet configured to receive a flow of plastic slurry, an outlet, three or more concentric bodies that rotate relative to each other, each body comprising a plurality of apertures to define a flow path through each body, wherein the plastic slurry traverses the flow path from the inlet to the outlet via the at least one aperture of each body to produce an outlet plastic slurry. Also provided are systems for processing plastic, comprising the macerator. Also provided are methods of manufacturing a composite wood product that comprises plastic particles.

Abstract: The invention relates to macerator for processing a slurry, the macerator comprising an inlet configured to receive a flow of inlet slurry comprising particles having an average particle size of less than 20 mm, an outlet, two or more bodies that rotate relative to each other, each body comprising a plurality of apertures to define a flow path through each body, wherein the slurry traverses the flow path from the macerator inlet to the macerator outlet via the at least one aperture of each body to produce an outlet slurry.

Abstract: This invention is directed towards apparatus for the production of water from air, and in particular for the production of drinking water. The apparatus includes an air intake device adapted to move air into the apparatus, an evaporator adapted to freeze the water contained in the air issuing from the air intake device and defrosting means adapted to defrost the water frozen by the adapter; the volume of air passing over the frosting surface of the evaporator; evaporator being controlled by either the air intake device or the evaporator. In an alternative form the apparatus may include an air intake device adapted to move air into the apparatus, an air temperature controller to control the temperature of the air entering the apparatus, an evaporator adapted to freeze water contained in the air issuing from the temperature controller and a defroster adapted to defrost the water frozen by the evaporator.
