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 for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

A gypsum washer includes a rotating trommel receiving raw material and a flow of water, and having paddles tilted to reduce impacts of the gypsum passing through the trommel while still providing a washing action. Bentonite separates from the gypsum in the trommel, liquifies, and is released through a mesh screen at the end of the trommel separating from the gypsum. The gypsum is released from the trommel into a water fed trough, scooped from the trough, and released into a storage area. The liquified bentonite is carried by a water flow into one or more settlement tanks, and recovered for use.

Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.

A system and process for closed loop system for removing particulate from a coal fired power wash water waste stream comprising a submerged flight conveyor for receiving used wash water, a bleed line for diverting wash water from the submerged flight conveyor, a filter for removing particulate from the diverter wash water, and pumps to recirculate the wash water on a loop through the system.

A system and method reclaims select components containing rare earth metals of electronic media electronic storage devices such as hard disk drives, solid state drives and hybrid hard drives and destroys the data containing components thereof. The system employs first devices, such as milling tools, to loosen various components of the storage device. The various loosened components include the components containing the rare earth metals and the data containing portions. Second devices, such as pick and place mechanisms, are provided for removing components from the storage device. A holding chassis receives the storage device, and moves the storage device for engagement with the first and the second devices. A section is provided for destroying the data containing portion of the electronic media storage device.

The invention relates to a device for the treatment and separation of inorganic solid wastes that can be used, for example, at home and/or near waste disposal areas. The device comprises a grinding chamber for obtaining waste fragments from a group of inorganic wastes and a sieving assembly of the fragments generated in said chamber. The device according to the invention also comprises a recognition assembly for recognizing the type of waste of each individual fragment and a distribution group, operatively interposed between the sieving assembly (6) and the recognition assembly, to place each individual fragment in a corresponding location of analysis of a recognition plate (9) of the recognition group. The device according to the invention is further provided with a monitoring and drive unit (200) configured to act on the recognition plate (9) so as to deposit each single analyzed waste fragment in a respective collection bin (13).

An apparatus for carrying out size reduction of battery materials under immersion conditions can include a housing configured to hold an immersion liquid comprising at least one of sodium hydroxide and calcium hydroxide. A first feed chute may define an opening therein for receiving battery materials of a first type into the housing and a first submergible comminuting device may be disposed within the housing and submerged in the immersion liquid to receive the battery materials of the first type from the first feed chute. The first submergible comminuting device may be configured to cause a size reduction of the battery materials of the first type to form a first reduced-size battery material.
