An eggshell membrane separation system of separating a broken egg into an eggshell and an eggshell membrane (100) including: a pulverizer (10) that pulverizes the broken egg; an alkaline water tank (20) in which alkaline water is synthesized; and a separation tank (30) in which the alkaline water is supplied from the alkaline water tank and the broken egg pulverized by the pulverizer is separated into the eggshell and the eggshell membrane, wherein the alkaline water discharged from the separation tank is returned to the alkaline water tank (20) and reused. The eggshell membrane separation system can improve a separation property of an eggshell and an eggshell membrane and smoothly discharge the eggshell precipitated in the separation tank.

A method of recycling laminated fabrics and laminated fabric products and producing new laminated fabrics and laminated fabric products includes the steps of shredding scrap or used laminated fabric material, melt separating the polymers, pelletizing the melt separated polymers, extruding the pelletized material with at least one virgin material to form a film, and laminating the film to a nonwoven material to form a new laminated fabric. The scrap or recycled laminated fabric products can include plastic/polymer materials having different melting temperatures. The new laminated fabric can be utilized to produce new products, such as protective covers.

In a process for transforming waste material into useful material, a quantity of waste material such as household garbage or municipal solid waste is provided. The waste material is pre-shredded into pre-shredded waste material. The pre-shredded waste material is processed to at least partially remove one or more selected material components, thereby providing a processed pre-shredded waste material. The processed pre-shredded waste material is then secondarily shredded into secondarily shredded waste material which is then hydrolyzed under pressure greater than ambient pressure to create an aggregate cellulose pulp.

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 continuous liquefying system for thermochemical treatment of plastic that has two different devices and complements. The devices comprise a first device, a second device, and a coupling device. In the first device, filled with water, the plastic is feed using a screw in a first port. The first device is used as a water airlock. The plastic is extracted from the first device using the coupling device having a screw, and is sent to the second device. From the first device to the second device there is a lateral screen, responsible for the retention of water. The second device has tubes filled with a heating fluid, that actuates heating the plastic material. The plastic material is liquefied and could be sent to other applications, such as thermochemical processes, thermoforming, and others.

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 method for designing one part of an electrostatic separating device of a mixture of different material granules, the method including providing a sorting performance value to be met by the device when at least one predefined mixture is introduced into the device to be sorted, optimizing a value of at least one parameter of the set of parameters relating to the device part by using an optimization technique, the optimization technique including the use of a sorting performance model of the device, and the optimization technique occurring under the constraint that the sorting performed by the device has the given sorting performance value.
