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.

Disclosed is a method for reducing methane emission from slurry (2) produced in a livestock farm (1). The method comprises the steps of guiding the slurry (2) from the livestock farm (1) to a dewatering unit (12) in which the slurry (2) is at least partially dewatered by extracting a watery fraction of said slurry (13), guiding the slurry from the dewatering unit (12) to a steam dryer (3), drying the slurry in the steam dryer (3), guiding the dried slurry (4) into a pyrolysis reactor (5) to produce pyrolysis gas (6) and biochar (7) through a pyrolysis process in the pyrolysis reactor (5), guiding at least a portion of the pyrolysis gas (6) to a combustion unit (8) in which the pyrolysis gas portion is combusted to raise the temperature of the combusted pyrolysis gas (9), guiding the combusted pyrolysis gas (9) to the pyrolysis reactor (5) to drive the pyrolysis process, guiding the combusted pyrolysis gas (9) from the pyrolysis reactor (5) to the steam dryer (3) to increase the temperature of steam (10) in the steam dryer (3), and heating the watery fraction of the slurry 13 to a temperature at least above 75° Celsius by means of the steam (10) from said steam dryer (3). Furthermore, a slurry treatment plant (20) for reducing methane emission from slurry (2) is disclosed.

Disclosed are a kitchen waste treatment system and a method thereof. The kitchen waste treatment system includes a control module, a drying module, an air extraction module, a grinding module and a temperature sensor all connected with the control module. The control module is for sending a first control signal, a second control signal and a third control signal according to a current working process in a determination that it is turned on normally. The drying module is for drying kitchen waste. The air extraction module is for extracting air from the kitchen waste. The grinding module is for grinding the kitchen waste. The temperature sensor is for detecting a temperature of the drying module. The control module is further for sending a stop command to the drying module in a determination that the temperature is higher than a preset temperature threshold.

A solar panel cutting unit according to an embodiment can separate layers of a solar panel from each other at once. The solar panel cutting unit separates thin layers of a solar panel from each other and includes a frame, a panel transporting mechanism that is provided at the frame and lowers the solar panel in a vertical direction such that adhesion lines of the thin layers are arranged downward, a pair of guide roller units that is positioned below the panel transporting mechanism and guides and lowers the solar panel, and a wire cutting mechanism that includes a pair of support rollers and cutting wires which connect the support rollers to each other and extend in the same direction as the adhesion lines such that the wire cutting mechanism separates the thin layers of the solar panel from each other.
