Waste management system
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.
Feeding arrangement for a granulator and granulator comprising such a feeding arrangement
An accumulation device that is operable in a feeding arrangement of a granulator, for accumulating flat material to be granulated, includes a first guiding device and a second guiding device. The accumulation device further includes a rotational shaft arranged to connect the accumulation device to the feeding arrangement. The first and the second guiding device are fixedly arranged in relation to each other so that when the accumulation device is rotated around its rotational shaft, the first guiding device as well as the second guiding device is rotated around the rotational shaft. A feeding arrangement and a granulator including such an accumulator device are also provided.
FEEDING ARRANGEMENT FOR A GRANULATOR AND GRANULATOR COMPRISING SUCH A FEEDING ARRANGEMENT
Disclosed is an accumulation device (150) operable in a feeding arrangement (110) of a granulator, for accumulating substantially flat material to be granulated. The accumulation device (150) comprises a first guiding device (152) and a second guiding device (154). The accumulation device (150) further comprises a rotational shaft (156) arranged to connect the accumulation device (150) to the feeding arrangement (110). The first and the second guiding device (152, 154) are fixedly arranged in relation to each other so that when the accumulation device (150) is rotated around its rotational shaft, the first guiding device (152) as well as the second guiding device (154) is rotated around the rotational shaft (156). Disclosed are further a feeding arrangement (110) and a granulator comprising such an accumulator device (150).
METHOD OF SEPARATING MATERIALS FROM AN OBJECT
The present invention relates to a process for treating an object comprising a first material and a second material bound to the first material by centrifugal force. A process for treating an object comprising a first material which is a thermoplastic polymer and a second material selected from the group consisting of silicones, polyurethanes, fluorinated polymers, rubbers and polyvinylchloride bound to the first material, wherein the density of the first material is different from the density of the second material, said process comprising the following steps: (i) physically treating the object to obtain micronized particles, (ii) suspending the micronized particles in an acidic or alkaline solution to at least partially separate the first material from the second material, (iii) recovering the solids from the suspension obtained in step (ii) and suspending the recovered solids in a liquid composed of water and dissolved salt and having a density which is between the density of the first material and the density of the second material, and (iv) separating the first material from the second material by applying a centrifugal force to the suspension obtained in step (iii).
