Genius Machinery has introduced a new plastic washing recycling line for South America. The Screw Press Dewatering Machine is the key to the line.

Plastics are generally recycled back into oil in massive facilities, but a Japanese inventor has built a tabletop machine that can accomplish the same task safely and cleanly ...

The machine is based on an open-source blueprint of a 3D-printed tattoo machine that he downloaded from GitHub. Then he added some unique ink: a mixture of saline and finely ground plastic.

Water pools at the bottom of the machine and is recycled back into the plant. The dried stuff, the "sludge cake," then drops onto a conveyor belt that extends out diagonally from the machine.
