A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. 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 frozen to a temperature at or below minus fifty degrees Fahrenheit, 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 may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

The invention discloses a vacuum cracking apparatus for a power battery and a cracking method thereof. The cracking device comprises a cylinder and further comprises a rolling device, a first sealing device, a cracking device, a second sealing device, a pyrolysis device and a third sealing device which are arranged from top to bottom.

A process for fracturing and devolatilizing coal particles rapidly exposes coal particles to a high temperature, oxygen-depleted work zone for a sufficient time period to cause volatile matter within the coal particles to vaporize and fracture the coal particles. The work zone has a temperature in the range from 600° C. to 2000° C. The coal particles are exposed to the high temperature, oxygen-depleted work zone for a time period less than 1 seconds, and preferably less than 0.3 second. The vaporized volatile matter is condensed and recovered as microcarbon particles.

A method for treating process material using a plurality of autoclaves, wherein each of the plurality of autoclaves cycles through the following: introducing steam from one or more of the plurality of autoclaves into an interior of a vessel; increasing the temperature within the vessel by adding heat to the interior of the vessel using an indirect heat source; reducing the temperature and pressure within the vessel by flashing a portion of the steam within the interior of the vessel to another one of the plurality autoclaves; increasing the temperature within the vessel by continuing to add heat to the interior of the vessel using the indirect heat source; and reducing a moisture content of the process material in the interior of vessel to a predetermined value by venting a remaining portion of the steam to another one of the plurality of autoclaves.

According to the present invention fragmented material 2, e.g. made from a material having Polyamides, is passing through a liquid bath 6 filled with liquid nitrogen 7 to cool the fragmented material 2 before entering a mill 10 for grinding the fragmented material 2. The fragmented material 2 is moved through the liquid bath 6 by exciting mechanical vibrations in the liquid bath 6 e.g. by a vibrational motor 28 coupled to the liquid bath 6 and/or an ultrasonic resonator 26 attached to the liquid bath 6. The invention allows to grind even materials being difficult to grind by reaching a temperature of −150° C. and less before entering the mill 10 while avoiding a direct cooling e.g, by introducing liquid nitrogen directly into the mill 10.
