This technology makes use of heat generated by using and combusting pellet fuel made from melting nonrenewable high-caloric waste plastic as a fuel of the pellet combustion burner.

Form of technologies

Drum-rotation melting method

Principle of technologies

• After pellet is made by melting crushed waste plastic, the pellet is combusted at the temperature of 1,000~1,300℃ inside the combustion burner in the processes of liquefaction -> evaporation -> ignition.
  

※ Pellet fuel
- It is a fuel of a certain size made with the process of extrusion molding of soft plastic such as LDPE and PS.
- It is a fuel of a certain size made with the process of crushing of hard plastic such as PETE, HEPE, and PP.
