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: The present invention relates to egg chambers for use in collection, inspection and selection of eggs for in vitro fertilization (IVF) procedures. The egg chamber, in use, provides an effectively closed and fluid filled system which minimizes the environmental changes that a harvested egg is exposed to, thus maximizing viability. The egg chamber comprises a vessel which can be made airtight, comprising at least one side wall, an upper wall and a lower wall, at least a portion of the upper wall being transparent and at least a portion of the lower wall being light permeable; a first inlet with a sealable port; a first outlet with a sealable port; a filter with a pore size appropriate for egg collection disposed within the vessel between the first inlet and the first outlet and configured to separate the vessel into a first internal chamber and a second internal chamber.
