With the rapid development of the plastics industry, the recycling of waste plastic as an energy saving, environmental protection measures, widespread attention. Especially in developed countries, started early work in this area has received a significant benefit.

The United States is the world of plastic-producing countries. The United States as early as the 1960s had already begun extensive research recycling of waste plastics. If it does not accelerate the pace of recovery of waste plastics, the United States will not be able to withstand the the growing waste plastics arising from environmental pollution and the loss to the economy. Proportion of the United States the use of Plastic Recycling Machine recycling waste plastic varieties: 50% of packaging products, building materials 18%, consumer goods 11%, 5% of the auto parts, electrical and electronic products, other plastic varieties proportion of polyolefin accounted 61% PVC 13%, accounted for 10% of polystyrene, polyester 11%, other 5%. The late 1980s, the United States nearly 10% recovery of waste plastics. According to statistics, the United States in the late 20th century waste plastic recycling rate of 35% or more. , Combustion of waste plastics recycling energy increased by 3% in the 1980s to 18%; burial of waste products from 96% down to 37%. American use of heat in the combustion of waste plastics, thermal decomposition to extract chemical raw materials, such as a lot of work and achieved some results. In addition, any State of the United States to resolve the problem of plastic waste has increased investment in the Plastic Recycling Equipment, the legislation also use tough measures.

Japan is the second largest country in the production of plastic. In the 1980s, the average annual waste plastics emissions accounted for 46% of the production. Visible, and the recycling of waste plastics has become a serious social problem in Japan. And Japan is an energy shortage in the country, and the recycling of waste plastics has been maintaining a positive attitude. The early 1990s, Japan recycling waste plastic rate of 7%, combustion heat rate of 35%. Japan is a world leader in the development and application of mixed waste plastics. Such Mitsubishi Petrochemical Co. the developed REVERZER equipment can be made of a variety of recycled products containing non-plastic content of up to 2% (such as paper) mixing the thermoplastic plastic scrap, Japan about more than 20 units of such a device, with 30 The number of companies using this Plastic Recycling Machinery  processing recycled products.
