A reformulated barrier material for use as an alternative cover for landfills made from recycled materials which may comprise construction and/or demolition debris to which is added tire derived rubber particles to inhibit the release of hydrogen sulfide gas through the reformulated barrier material to the surrounding atmosphere from the landfill beneath.

A mobile picking system for sorting a plurality of materials has a support frame upon which a conveyor arrangement is mounted. The conveyor arrangement is configured to convey the materials from one end of the support frame to the opposing end. At least one picking station is provided upon the support frame adjacent said conveyor arrangement. The support frame is variable between a working configuration and a transporting configuration by a plurality of support legs which are coupled to the support frame. The conveyor arrangement has a picking conveyor and a feed system.

The disclosure relates to a device (1) for recycling building material (2), which contains a base material and a binder, with a receiving container (3, 3a, 3b) for the building material (2), wherein the building material (2) in the receiving container (3, 3a, 3b) can be acted upon by at least one nozzle (4) with a high-pressure water jet (5) for detaching the binder from the base material. Furthermore, the disclosure relates to a method for recycling building material (2).

A cyclonic separation and materials processing method and system is presented in which materials entry at one end and which is arranged so that the materials that enter will be given a tangential velocity component as they enter. Specific embodiments include a three-dimensional sorting system with the use of an outward centrifugal motion and up/down (or vertical) motion flow of water or other media, which can be thought of as a three-dimensional separation.

A system for processing solid and liquid waste includes a first shale shaker, a second shale shaker, a submersible pump, a centrifugal pump, a first collection tank, a second collection tank, a mud cleaner assembly, a variable frequency drive (VFD) centrifugal solid-liquid separator, and a water clarifying assembly. The first shale shaker is in fluid communication with the second shale shaker through the submersible pump. The second shale shaker is in fluid communication with the centrifugal pump through the first collection tank. The centrifugal pump is in fluid communication with the mud cleaner assembly. The mud cleaner assembly is in fluid communication with the VFD centrifugal solid-liquid separator through the water clarifying assembly. Resultantly, the system discharges a flow of usable water through the VFD centrifugal solid-liquid separator as an initial load of solid and liquid waste is inputted into the first shale shaker.

The present disclosure relates to an apparatus and method for processing old concrete. The old concrete comprises cement rock and an aggregate, including sand and/or gravel. The method includes: grinding the old concrete in a grinding device; classifying the ground old concrete in a classifying device into at least two products of different grain fractions. The grinding is effected at a grinding pressure of less than 50 MPa. The apparatus includes a grinding device for grinding the old concrete, and a classifying device for classifying the ground old concrete into at least two products of different grain fractions. The grinding device is designed, and configured, in such a way that the grinding of the old concrete is effected at a grinding pressure of less than 50 MPa.

The invention relates to a system (1) for recycling waste plaster originating from the general public and intended to recover a fraction, referred to as final fraction, comprising elements of particle size smaller than or equal to a determined threshold size, the system (1) comprising: at least one waste preparation unit (2); at least one unit (3) for crushing and sorting the waste from the preparation unit (2); at least one recovery unit (5) recovering at least part of the fine fraction from the crushing and sorting unit (3); the system (1) being characterized in that it further comprises at least one finalization unit (4) receiving at least part of the coarse fraction from the crushing and sorting unit (3), the finalization unit (4) comprising at least one rolling mill having a roll separation less than or equal to the threshold dimension.

The disclosure relates to a device (1) for recycling building material (2), which contains a base material and a binder, with a receiving container (3, 3a, 3b) for the building material (2), wherein the building material (2) in the receiving container (3, 3a, 3b) can be acted upon by at least one nozzle (4) with a high-pressure water jet (5) for detaching the binder from the base material. Furthermore, the disclosure relates to a method for recycling building material (2).

This application discloses a separator for separating and recovering materials from a waste stream. The separator has a cyclone having a top section and a bottom section, an impeller within the cyclone, a media inlet for accepting a flow of media or a pulsating flow of the media operatively connected to the impeller in which media or fluid flows through the impeller into the separator; a first discharge passage for a collecting a light fraction, and a second discharge passage for collecting a heavy fraction.

Aqueous slurry which includes solid foreign matter and paper dust is pressed by means of a screw press, provided with a mesh having openings not less than 1.5 mm and not greater than 3 mm, to separate the aqueous slurry into the solid foreign matter and the paper dust, and liquid component passing through the mesh. Then, the liquid component is sieved by means of a sieve having openings not greater than 1 mm to separate from the liquid component the solid foreign matter and the paper dust.
