The present invention relates to a technology for recycling waste resin, and more specifically, when extracting oil stream components by pyrolyzing and distilling the collected waste resin, it is possible to improve the efficiency while reducing various contaminants such as waste water. It relates to a waste resin emulsification plant system that does not generate

In general, synthetic resin, which means plastic, is easy to mold and polymerizes various materials using petroleum as the main raw material to easily impart properties required by users. The resulting waste is also increasing in amount, and its disposal has emerged as a social problem.

Currently, most of this large amount of waste resin is incinerated and landfilled, and only a part of it is recycled. Since it is connected, recycling is recommended, and conversion of waste resin into energy is being considered as the main method of waste resin recycling.

In particular, in response to the fact that the reserves of petroleum, which is the fuel used to produce resin products, are decreasing and the price is increasing, the oil component in the waste resin is reduced and recovered, and the degree of resource recycling is improved. A lot of research is being done to improve it.

Conventional methods for recovering other resources from the collected waste resin include extracting oil from the waste plastic through heat treatment, or crushing the waste into small pieces and then mixing it with other materials to produce solid fuel rods.
