What Is the Application of Plastic Recycling?

What is plastic recycling?

Plastic recycling refers to the use of certain recycling processes to recycle and reuse waste plastics to achieve the purpose of turning waste into treasure. The waste plastics in our country are mainly plastic films, plastic filaments and woven products, foamed plastics, plastic packaging boxes and containers, daily plastic products, plastic bags and agricultural mulching films.

Recycled materials

With the rise in global crude oil prices, the price of plastic products, one of the derivatives of petroleum, has naturally risen, and the recycling of waste plastics has also been mentioned in the first place. The recycling of waste plastics has been widely adopted by modern industrial enterprises. After the waste plastics are manually screened and classified, they must go through processes such as crushing, granulation, and modification to become various transparent and opaque plastic particles, which are then classified according to their appearance, and finally become recycled materials that can be reused.


Initially, plastic recycling was largely landfilled or incinerated, resulting in huge waste of resources. Therefore, foreign waste plastics are used in blast furnace injection instead of coal, oil and coke, in cement rotary kilns instead of coal to burn cement, and into waste solid fuel (RDF) for power generation, with ideal results.

RDF technology was originally developed in the United States. In recent years, in view of the shortage of landfills in Japan, the serious corrosion of HCI to boilers when incinerators treat chlorine-containing waste plastics, and the production of dioxins during the combustion process to pollute the environment, the high calorific value of waste plastics is used to mix various types of waste plastics. After using the characteristics of high calorific value of waste plastics to mix various combustible wastes to make RDF with a calorific value of 20933kJ/kg and a uniform particle size, even if chlorine is obtained. Dilution is also convenient for storage, transportation and for other boilers and industrial furnaces to burn substitute coal.

Power generation

Waste solid fuel power generation was first applied in the United States, and there are 37 RDF power stations, accounting for 21.6% of waste power stations. Japan has realized the huge potential of waste plastic power generation. In Japan, some small waste incineration stations have been changed to RDF production stations in conjunction with the overhaul, so that continuous high-efficiency large-scale power generation can be carried out after centralized, so that the steam parameters of the waste power station have been increased from 30012 to about 45012, and the power generation efficiency has been increased from the original 15% to 20% -25%.
