Plastic recycling refers to the use of certain recycling processes to recycle waste plastics to achieve the purpose of turning waste into treasure. With the increasing consumption of plastic products, the amount of waste plastics is also increasing. Automotive plastics, electronic and electrical appliances and home appliances supporting plastics, etc. These products become one of the important sources of waste plastics after the end of life. Their storage, transportation, processing, waiting to be processed by the application of waste plastic raw materials and reprocessing, if not properly, will inevitably damage the environment, endangering people's health.
Global crude oil prices rise, as one of the oil derivatives of the price of plastic products naturally also rose, the recycling of waste plastics has also been mentioned in the first place. Recycling of waste plastics has been commonly adopted by modern chemical enterprises. Waste plastic after manual screening and classification, but also through the crushing, granulation, modification and other processes, into a variety of transparent and opaque plastic particles, and then classified according to the quality, and finally become recycled materials can be reused.
Initially, a large number of plastic recycling landfills or incineration methods, resulting in a huge waste of resources. Therefore, foreign countries will use waste plastic blast furnace blowing instead of coal, oil and coke, cement rotary kiln instead of coal to burn cement, as well as made of refuse solid fuel (RDF) for power generation, the effect is ideal.
Blast furnace blowing waste plastics technology is the use of waste plastics of high calorific value, waste plastics as raw materials made of suitable particle size sprayed into the blast furnace, to replace the coke or pulverized coal, a new method of handling waste plastics. Foreign blast furnace blowing waste plastics application shows that the utilization rate of waste plastics up to 80%, emissions for the incineration amount of 0.1% - 1.0%, resulting in less harmful gases, lower treatment costs. Blast furnace blowing waste plastic technology for the comprehensive utilization of waste plastics and governance “white pollution” opened up a new way, but also for metallurgical enterprises to provide a new means of energy efficiency.
