In the scene of the documentary film "plastic Empire", on the one hand, there are mountains of plastic waste in China; On the other hand, Chinese businessmen are constantly importing waste plastics. Why import waste plastics from overseas? Why is the "white garbage" that China often sees not recycled? Is it really that scary to import waste plastics? Next, let's analyze and answer. Plastic granulator

Waste plastics, the key is to refer to the leftover materials in the plastic production process and the crushed materials of waste plastic products after recycling. Many applied plastic products, such as electromechanical engineering casings, plastic bottles, CDs, plastic barrels, plastic boxes, etc., can still be used as raw materials for plastic production and processing after disinfection, cleaning, crushing and re granulation. The performance parameters of some waste plastics are even better than those of general anti-corrosion coatings.

1、 Recycling, there are a lot of commonly used (plastic granulator)
After recycling, waste plastics can be made into many other objects, such as plastic bags, plastic barrels, and other daily plastic products. It only needs to change some of the characteristics of the original plastic and even the use of the new plastic, which is not only related to the high ecological value of the plastic, but also related to the production and safety of the plastic according to the characteristics of the original metal alloy.

2、 China demands, needs but not enough
As a plastic producing and consuming country in the world, China has produced and manufactured 1 / 4 of the world's plastics since 2010, and the consumption accounts for 1 / 3 of the world's total output. Even in 2014, when the improvement of plastic manufacturing industry gradually slowed down, China's production of plastic products was 7.388 million tons, while China's consumption reached 9.325 million tons, an increase of 22% and 16% respectively over 2010.
The huge demand makes plastic raw materials become necessary products with huge business scale. Its production and manufacturing comes from the recycling, production and processing of waste plastics. According to the analysis report of China's renewable energy and electronic products recycling industry released by the Ministry of Commerce, 2014 was the highest amount of recycled waste plastics across the country, but it was only 20 million tons, accounting for 22% of the original consumption.
The import of waste plastics from overseas is not only lower than the cost of imported plastic raw materials, but also the key is that many waste plastics can still maintain very good production and processing characteristics and organic chemical index values after being solved. In addition, the import tax and transportation costs are low, so there is a certain profit space in China's production and processing market. At the same time, recycled plastics also have a great market demand in China. Therefore, with the soaring price of anti-corrosion coatings, more and more companies import waste plastics to control costs.

Why is the "white garbage" that China often sees not recycled?
Waste plastics are a kind of resource, but only the cleaned waste plastics can be reused for many times, or used again for granulation, refinery, paint making, building decoration materials, etc. At this stage, although waste plastics already have a variety of main uses, they are not very sound in the technology of recycling, screening and solution. The secondary recycling of waste plastics must be very time and cost, and the quality of raw materials produced and processed is also very difficult.
Therefore, the research and development of excellent production equipment and comprehensive utilization technology to promote the reuse of waste plastics to achieve harmless treatment and rational utilization are the technical assistance to reduce air pollution; The formulation and implementation of rules and regulations for waste classification, recycling and utilization is the fundamental prerequisite for the rational remediation of "white waste".

3、 Rely on external sources to save energy
The import of waste plastics and the recycling and granulation of waste plastics can not only reduce the contradiction between the supply and demand of plastic raw materials, but also save a lot of foreign exchange transactions of China's imported oil. The raw material of plastics is crude oil, and China's coal resources are relatively limited. Importing waste plastics can alleviate the problem of resource shortage in China.
For example, coke bottles and plastic Aquarius, which can be easily discarded, are a very large mineral resource if they are recycled and centralized. A ton of waste plastic can produce 600kg vehicle gasoline and diesel engine, which saves resources to a great extent.
With the increasing shortage of ecological resources and the continuous rise of raw material prices, the production and manufacturing of secondary raw materials is increasingly concerned by industrial producers and operators. Using recycled plastics to carry out production and manufacturing can reasonably improve the competitiveness of industrial producers and operators from the two-way aspects of economic development and environmental protection. Compared with new plastics, using recycled plastics as raw materials to carry out production and manufacturing can reduce energy consumption by 80% to 90%.
