Developed countries waste plastics strategies

Currently, the majority of waste plastics are thermoplastics, due to the molecular structure is not too much damage, after sorting, washing, drying, grinding, mixing the ingredients, granulating, such a process can be re-processed into plastic products. Waste plastics and renewable energy than new material resin savings of 85% to 90%, saving energy processing 6% to 17%.
After the waste plastics processed into granules, the material still has good overall performance, meet blown film, drawing, tube drawing, injection molding, extrusion profiles and other technical requirements, widely used in plastic products.
Japan, as one of the countries producing plastic, plastic scrap its huge annual emissions, accounting for 30% to 50% of household waste by volume. Coupled with Japan’s land area is small, densely populated and has a lot of plastic waste cannot be incinerated or buried use manner. On the other hand, Japan’s lack of resources, companies need plastic waste as a resource to be recycled, the establishment of a recycling-oriented society.

At present, Japan will not be able to collect a single species, it is difficult according to the type of plastic waste sorting as heat recovery, substituted for blast furnace coke as a reducing agent, is used as a fuel in cement kilns. Fuel used for a variety of re-generating boilers, part of the oil fuel can be used in cars , including solid fuel technology, fuel-based powder, an aqueous slurry of solid fuel technology, thermal decomposition of oil and so on.
Plastic waste oil can get higher-value liquid fuel or chemical raw materials, and other heat recovery and fuel-based method can only be referred to alternative coal or gas, it is the oil recovery method stipulated by the Government of Japan mixed waste plastics. It is internationally recognized as the ideal method.

Italy is the recycling of waste plastics in Europe doing the best work of the State. Italian waste plastics accounted for about 4% of municipal solid waste, the recovery rate of up to 28%. In addition, Italy has also developed a separate waste plastics from municipal solid waste in machinery and equipment.

The United States had carried out the recovery and utilization of waste plastics in the early 1960s, on the use of thermal energy is extracted from the thermal decomposition of waste plastics technology research chemical raw materials, has achieved some success. In addition to solving the problem of plastic waste, states also adopt legislative and other compulsory measures. Plastic recycling are popular in many developed countries, as a developing country, China should accelerate the pace of recycling industry.
