1: Identification Technology

     Many varieties of plastics, the lack of practical identification techniques on-site operations, experience-based judgments; identification is the most basic technology, are very particular about the experience, there is no 3-year, 5 years is difficult to grasp the full; combustion, he said: would like to make a fortune on the Wantong Business Alliance to find high-quality supplier! Identification burning is the most common, but requires experience and the beginning of the experience, the fact there is a simple mature experimental method can identify more than 10 kinds of different types of more than 100 kinds of plastic, do not hand janitor work, procurement of waste when the is easy to take the eye, we are familiar with the product either high prices or no cargo.

     2: Cleaning, Cleaning Technology

     Pollution-free plastic cleaner, cleaning technologies (plastic surface of the coating, self-adhesive paper, paper, metal, wood and other impurities, recycled plastic odor get rid of cleaning effect demanding applications: such as PET Bottle Flake). A lot of Solvent-based cleaning technology is simply poisoned by humans, be very careful not to use the peer calls, including the recently recommended websites out is no exception, have recently seen a lot of places recommend a specific field of plastic waste used in detergents, said here solvent-based cleaning agent, said several major hazards, Wang peers also express their views, we discussed:

     The first major hazards: poison specific operations staff, sterilization " cancer " leukemia and malignant lesions are many, and many organic solvents on.

     The second-largest hazard: pollution of water sources;

     The third-largest hazards: prone to fire and explosion;

     The fourth-largest hazards: nothing has changed in appearance from the feeling, the fact a lot of solvent on the plastic, especially the great influence on the performance of engineering plastics, but no testing equipment can not come out with the naked eye.

     5th: the need for more heat to be careful, highly volatile solvents, heating is very easy to lapse, saying that can be repeated use, with a secondary hard to say how kind of back.

     3: Separation Technology

     1, the separation of plastics in a variety of impurities: the density sub-selected wind selection, all kinds of water-election of the other mature media, sorting equipment such as electrostatic election, magnetic separation;

     2, the same density, mixed plastics separation technology (PET / PVC, ABS / HIPS, PP / PE, a variety of electrical mixed plastics) (the world's leading plastic flotation technology, Guangzhou Iron and Steel factory MBA core technology)

     3, the same kind of plastic particles of different color separation technology

     This is the plastics recycling industry's core technology, difficult and high added value.

     4: special plastics recycling

     Composite membrane recycling technology, composite  plastics recycling;

     This is a lot of two days, many websites selling German sausage composite films message, only 100 euros a ton, cheap ah, is because the composite membrane is very difficult to recall the reason. However, most packaging Chinese sausage is a thing called PVDC do not know in Germany and domestic What is the difference there are two kinds of composite  plastics recycling methods, one of separation, one is modified, can greatly increase their added??. However, a great technical difficulty.

     5: Unable to form a closed loop of the pollution problem

     1, the cleaning process of sewage treatment

     2, granulation process gas pollution, odor repel.

     3, can not be recycled garbage disposal problem

     6: recyclable resources and recycled plastic materials and application of the valuation to determine the direction of

     1, the vast majority of enterprises lack a basic inspection and test equipment, the lack of features based on the resource itself, recognized the pricing basis;

     2, recyclable resources and recycled plastic materials classification, grading the lack of operational standards;

     3, lack of systematic application of renewable materials research;

     7: Recycling materials stable performance and modification

     This is also the  plastics recycling industry can improve the technical content of the key technical aspects, but at present most of  plastics recycling businesses do not have the technology and concept, the reality of an increasingly competitive environment, the recovery of materials stable performance and modification of the very significant important.

     8: Chemical Recovery Method

     Past hot plastic oil refining, for various reasons is still very immature, because big investment in equipment in recent years, developed slowly.

     9, recyclable plastic products design ideas to implement

     This is the plastics industry the key issues of sustainable development is to solve the source of the problem, but little push.

     10 Other

     These ten years of the most critical technical challenges are threefold: a: plastic sorting and separation technologies; 2: non-polluting clean " clean technology, 3: Valuation and application of the direction is one of the key issues.

With the rapid development of the plastics industry, recycling of waste plastics as a energy conservation, environmental protection measures are generally taken seriously. In particular, the developed countries, this area of work started early, has received significant benefits. The United States is the world's plastics producer. The United States as early as 60 years in the 20th century had already begun recycling waste plastics extensive research. But without accelerating the pace of recovery of waste plastics, the United States will not be able to withstand the growing environmental pollution arising from waste plastics, and to economic losses. The United States for recycling waste plastics proportion of species: 50% of packaging products, building materials 18%, consumer goods 11%, 5% of auto parts, electrical and electronic products 3%, the proportion of other plastic varieties of polyolefin, respectively accounting for 61%, 13% PVC, polystyrene, 10% polyester 11%, other 5%. Late 80s, the United States, nearly 10% recovery rate of waste plastics. According to statistics, the United States in the 20th century, the recovery rate of waste plastics for more than 35%. Among them, burning waste plastics to recover energy from 80 years of 3% to 18%; waste products buried in the rate from 96% to 37%. The United States the use of heat in the combustion of waste plastics, thermal decomposition of chemical raw materials in areas such as extracting a lot of work and achieved some results. In addition, the U.S. states to address the problem of plastic waste, the use of tough measures to the legislation.

Japan is the second largest country in plastics. The 20th century, 80 years, its average annual emissions of waste plastics accounted for 46% of production. Can be seen that the recovery of waste plastics has become a serious social problem in Japan. And Japan is the national energy shortage, so waste plastics recycling has maintained a positive attitude. The early 90s, Japan's rate of recycling of waste plastics 7%, the combustion heat rate for the use of 35%. Japan in the development and application of mixed waste plastics are also a world leader. As developed by Mitsubishi Petrochemical Co., Ltd. reverzer device can contain up to 2% of non-plastic components (such as waste paper) is made of a variety of hybrid thermoplastic waste plastics recycling products, Japan's more than about 20 such facilities, the world's 30 companies using this equipment, processing of renewable products.

Italy is the waste plastics recycling in Europe doing the best country. Italy's waste plastics account for about 4% of municipal solid waste and its recovery rate of up to 28%. Italy has also developed a separate solid waste from urban waste plastic machinery equipment. This recovery is expected to add new material, can ensure that it has sufficient mechanical properties, can produce garbage bags, profiles, hollow products.

The face of bottle waste, the Dutch government solution is to "solve the whereabouts of the waste." In August 2007, the Dutch government that provide access to gradually nationwide, so that people automatically collects plastic waste into plastic waste collection points, so that plastics recycling wastes have the chance. This means that 16 million residents will not only have a glass, paper materials, highly polluting products, such as batteries and perishables refuse to separate the waste collection bins, the details in later life, we should also pay attention to discarded plastic rubbish separately.

In the past, large quantity of waste plastics recycling environmental protection activities is limited to industrial areas, the remaining waste plastics. The management of some municipalities in 2007 the Netherlands began to offer their residents experimental plastics recycling. Points every household residents were large plastic bags a month to designate a day of street recycling. Other days, residents can also be handed personally to waste, municipal waste to the Recycle Bin. The pilot of waste plastics recycling operation was a Dutch national enthusiastic response. Survey shows that 91% of the Dutch population willing to participate in classification discarded plastic action. So the Dutch government to expand their operations in major cities and hundreds of small villages to provide comprehensive plastics recycling. At present the Netherlands domestic plastic waste from the private sector only 20% of plastic consumption is estimated that in 2012 can reach 42%.

Europe, wine and soft drinks manufacturers in general have provided empty bottle recycling service. Dutch consumer products to buy, must remand bottles of prepaid fees and custody fees box, use the bottle to retrieve a deposit before retirement. A variety of non-deposit fee on plastic bottles into waste plastic. People deal with the responsibility of waste plastic bottles is to first bottle washing and draining, and then riding bian to reduce the occupied space. Between the modern family kitchen and bathroom waste a lot of plastic containers. Once you can enjoy the facilities for recovery, the state will have access to vast resources of recycled plastic. Moreover, the plastics recycling technology directly to the protection of the environment make a significant contribution. After delivery of waste plastic pressed bricks, hot melt obtained after the regeneration of lipid particles. Can be made of polyester cotton, wigs, zippers serrated, green bags, glial bullets, bicycle mats, packaging, fruit trays and so on polyethylene. Japan and even recycled fiber clothing.

"A fire a clean" is not clean, the harmful effects of burning plastic generated when the two big British brewing on the environment and ecology of the toxic air. At the same time, it also burned a big stack notes. Europe's waste plastics recycling start fast, implementation of the intensity of large concentration of these waste plastic and even the remainder could be exported to Hong Kong and transfer to the mainland as a renewable resource.

Europe beats plastics packaging recycling target
