An analysis method and apparatus for treating polymer granules at least part of which comes from post-consumer recycling, in which a flow of a process gas is purified from contaminating vapours by traversing, in sequence, first a dust collector filter that retains the solid particles contained in the gas, then a first side of a gas/gas heat exchanger in which the process gas surrenders heat, then a condenser in which the process gas is cooled to below the boiling point of the contaminating vapours to form condensate, then a second side of the exchanger in which the process gas recovers a part of the previously transferred heat, to then enter a container where the polymer granules are treated.

A method of recovering filler material from a polymer material comprises (a) heating the polymer material to a first temperature; (b) heating the polymer material to a second temperature higher than the first temperature resulting in a pyrolyzed material; (c) elutriating the pyrolyzed material to obtain a separated mixture; and (d) filtering the separated mixture to obtain the filler material.

A method of separating infill material (105) of synthetic turf is disclosed. The infill material (105) comprises sand (155), rubber (165) and fibres (135). The method comprises combining the infill material (105) with water (106) to form an infill slurry (110), and separating one or more of the sand (155), rubber (165) and fibres (135) from the infill slurry (105). A hydrocyclone (104) may be used to separate the infill slurry (105) into a fibre slurry (107) and a sand/rubber slurry (111). An separation unit (200) for carrying out the method is also disclosed.

A method of treating and grading contaminated particulate material includes i. physically breaking up the particulate material to separate the particles thereof; ii. rinsing and grading the particulate material to separate the particulate material into an oversize fraction and an undersize fraction; iii. washing and grading the oversize fraction to produce one or more treated aggregate products; iv. passing the undersize fraction through a high shear washing process to separate contaminants therefrom; v. fluidising and cleaning the undersize fraction in a classification tank to produce one or more treated sand products at an underflow thereof by passing clean water upwardly into the classification tank. Optionally, waste water resulting from stages (ii), (iii) and (iv) is treated to form process water, a portion of which is used in stage (ii), a portion of the process water undergoing one or more further treatment processes to produce clean water used in stage (v).

Embodiments of the present invention may provide managing waste including providing non-sorted solid waste (1), processing non-sorted solid waste in a waste handling system (21), shredding (26) non-sorted solid waste to create shredded non-sorted solid waste (27) in a waste handling system; introducing shredded non-sorted solid waste into a thermochemical conversion reactor (4); heating and even chemically converting a shredded non-sorted solid waste; producing hydrochar (22) and a recyclable materials fraction (23); recycling water (24) used in the heating and chemically processing of the shredded non-sorted solid waste in a thermochemical conversion reactor in said waste handling system; sorting (25) the recyclable materials fraction; fueling (28) a thermochemical conversion reactor with hydrochar (22); and perhaps even recycling heat from a thermochemical conversion reactor in the waste handling system.

A method of upcycling fiber reinforced polymer source material by disassembling the source material into sections; planking the sections into longitudinal pieces; separating core material from the source material in the longitudinal pieces to make composite strips; preparing the composite strips; and remanufacturing the prepared composite strips into an article.

An ammunition disposal system having a chute access portion; a collection chamber attached such that a chute access portion interior cavity is in fluid communication with a collection chamber interior cavity; a shredder assembly attached such that the collection chamber interior cavity is in fluid communication with a shredder assembly interior cavity, with one or more shredder blade assemblies positioned within the shredder assembly interior cavity; a hopper attached such that the shredder assembly interior cavity is in fluid communication with a hopper interior cavity; an extractor attached such that the hopper interior cavity is in fluid communication with an extractor interior cavity, and wherein an auger is positioned within at least a portion of the extractor interior cavity; and a liquid contained within at least a portion of the collection chamber interior cavity, the shredder assembly interior cavity, the hopper interior cavity, and the extractor interior cavity.

The present disclosure relates to a method for preparing a wind turbine blade for recycling by sectioning the wind turbine into at least a first and a second wind turbine blade part comprising different types of materials or comprising the same type of materials in a different relative content.

The invention relates to a method and a system for separating dust-containing material mixtures which contain fibers, preferably glass fibers, and have heavy metal (SM) and/or precious metal (EM) from the process of recycling electric or electronic devices, wherein the method has at least one step (S1) of mechanically releasing particles from fiber-containing mixed material agglomerates in a dry manner and at least one step (S2) of mechanically releasing fiber-containing mixed material agglomerates in a dry manner.

Waste separator apparatus which comprises: -a frame (11) which delimits a separation chamber (12); -a screening mesh (13) which divides the separation chamber (12) into a shredding chamber (121) and a collection chamber (122); wherein the shredding chamber (121) has a loading mouth (123) and an unloading mouth (124); - a shredder shaft (14) fixed to the frame (11) in a rotatable manner about an operating axis (A) and extending into the shredding chamber (121). The shredder shaft (14) has first cutting hammers (15) and second expelling hammers (16); wherein the screening mesh (13) faces the first hammers (15), in order to receive shredded material, and the discharging mouth (124) faces the second hammers (16). The second hammers (16) have a front edge (17) which is rectilinear and extends substantially parallel to a radial direction (C) with respect to the operating axis (A).
