Tokyo Eco Recycle Recycle processes

This is the crusher which can be commonly used for crushing bodies of refrigerators, air conditioners and washing machines.
Looking inside the crusher, you can see remaining bodies are crushed one after another.
In this crushing process, various materials such as metals and plastics can be separated.

Small pieces of scraps obtained in the crushing process are sent from the crusher to a vibrating conveyor. Then, the suspended magnetic separator separates and recovers iron from these small scraps, using the attraction of magnet.

After iron is recovered, remaining scraps are further separated into larger ones and smaller ones by the vibrating sieve machine. This process is supposed to improve the efficiency of separation in the postprocess.
The next step is to send these scraps to the eddy current separator to recover nonferrous metals such as aluminum and copper.
An eddy current is a flow of electricity generated when nonferrous metals like aluminum and copper pass through a magnetic field caused by a magnet.
If an eddy current occurs, aluminum and copper try to get away from the magnet.
The mechanism utilizing this phenomenon is eddy current separation.
Equipment using this mechanism can easily separate copper or aluminum flown away by the eddy current and plastics falling down without being flown away.
Copper and aluminum are further separated by hand to separate these two materials.

Plastics are sent to the wind force plastics separator that can identify difference of specific gravities and separate "copper wire and heavier plastics" from "lighter plastics."
The pneumatic plastics separator is a two-stage separator resulting from the development process jointly conducted by Tokyo Eco and other company. It can contribute to highly accurate separation while reducing the cost by 50%.
Lighter plastics recovered in the previous process are further separated to achieve higher quality by clients who purchase them.
Vegetable compartments removed from refrigerators and tubs from washing machines are crushed with specific crushing equipment and reproduced as products’ raw materials.
As an example of thoroughgoing recycling, motors disassembled manually are further separated to recover resources by clients who purchase the motors.
Copper wire is separated into copper and coated layer using a newly developed copper recovery machine.
This machine can process even ultra-thin copper wire used in home appliances and recover copper of more than 99.9% purity.
Here, you can see a flow of the process how heat insulating polyurethane foam used in refrigerators are sent from the crusher.

This is a machine for recovering CFCs from heat insulating polyurethane foam used for refrigerators.
Polyurethane heat insulating foam recovered and sent from the crusher is sucked by the pneumatic polyurethane foam separator and sent to the fine grinding mill.
This process can expel any remaining CFCs from the heat insulating material.

The CFCs obtained from this process are recovered using the CFC recovery machine.
