With the plastic a large number of applications, into the
twenty-first century,
plastics recycling industry in China increasingly
prosperous market of SMEs, such as springs appeared, investment activity, from
the previous family workshops Recycling plastic model of the forward market
demand-driven business model of pure changes, and is developing a recycling
process clustering, market transactions are intensive in order to completely
depend on market demand and price-driven environment-oriented industrial
economy. At present, the number of
plastics recycling companies have tens of
thousands of recycling outlets throughout the country, has formed a number of
large-scale renewable
plastics recycling market and processing hub, mainly in
Guangdong, Zhejiang, Jiangsu, Fujian, Shandong, Hebei, Henan, Anhui, Liaoning
and other provinces in the plastics processing industry developed. One Zhejiang
Yuyao, Ningbo, Dongyang, Cixi, Taizhou; Nanhai, Guangdong, Dongguan, Shunde,
Shantou; Xinghua, Jiangsu, Changzhou, Taicang, Lianyungang, Xuzhou; wen'an
Hebei, Baoding, Xiong County, Yutian; Shandong Laizhou, Zhangqiu, Linyi; Henan
Anyang, Ge, Luohe; five river in Anhui and other places of recycled
plastics recycling, processing, management and increasing market size, annual turnover
was mostly in the hundreds of millions to billions of dollars, was booming
trend. In major cities around the country such as Beijing, Shanghai, Tianjin,
Chongqing, Guangzhou, Wuhan, Nanjing, Hefei, Xi'an, Taiyuan, Kunming, Chengdu,
Shenyang, Urumqi and other parts have a large number of similar processing,
trading gathering places. In recycled
plastics recycling and processing
enterprises and large and steady increase in the number of personnel, mainly
based on the self-employed and farmers, there are a number of other sectors
investors.
plastics recycling industry for rural economic growth, employment for
surplus rural labor force, and increase revenue to provide a channel for
resource recycling, environmental protection has made tremendous contributions
to the cause, is an important part of the environmental protection industry is
based on recycled plastics in their end of life After the still has a recycling
value of the existence of different forms of plastic, almost all thermoplastics
have recycling value. In the synthetic resin production processes, products and
semi-finished products in plastic production and processing process, the
logistics process and consumers in the plastic after use recycled plastics are
produced. In general the synthesis, processing, generated in the process known
as pre-consumer plastic; put through the circulation and consumption, resulting
from the use of the known post-consumer plastic. Produced a small amount of
pre-consumer plastic, quality and stability, renewable high-value, generally in
the production process to be handled properly, can be completely reused. We are
talking about post-consumer recycled plastics generally refers to loss of use
value of the recycled plastic products that can be recycled. Plastic recycled,
concentrated, classification, scientific and reasonable disposition of available
renewable after the value of achieving recycling. Import of waste plastic in the
part of an overseas pre-consumer plastic, the quality is better, higher-value
can be used as renewable raw materials should be encouraged to import large
quantities. The largest category of sources of recycled plastic varieties
plastic film (including plastic packaging bags and plastic), plastic wire, and
woven materials, foam products, plastic packaging and containers, cable coating
materials and a variety of household goods, sports entertainment, health care
and other household plastic products, including film, foam, boxes and
containers, knitting, sheets and other plastic products mainly used in plastic
packaging. There are also some other plastic packaging products (such as plastic
tray), agricultural plastic products (such as water-saving equipment,
agricultural plastic), plastic decoration products have a higher rate of
obsolescence. Plastic packaging consumption in 2004 of 6.344 million tons in
2005, more than 7 million tons, it is estimated that at least 80% within a year
were abandoned, is a major source of recycled plastics. This is similar to
foreign countries, such as the United Kingdom in 2001 the amount of plastic
packaging for the
plastics recycling 91.2% of the total amount recovered. There
are also a number of recycling or recovery of little value in the high cost of
disposal of a greater degree of difficulty, such as plastic composite,
ultra-thin packaging material, plastic film, disposable plastic products such as
impact on the environment should not be overlooked. But, like plastic pipe
fittings, profiles, enhance their anti-seepage geotechnical materials (including
waterproofing membrane), etc. In recent years, the use of structural plastic
materials grew larger, the actual service life is longer, the current period of
less than a large number of scrap Therefore, this part of the waste volume is
not significant. Home appliances according to their normal service life of 10 to
15 years was required to scrap the TV for more than an annual average of 5
million sets, washing machines, an annual average of 5 million units, about 400
million refrigerators a year, this will be phased out in China each year more
than 1,500 million units of waste appliances. In recent years, electronic
communications equipment such as computers, mobile phones, VCD, DVD, records,
CDs and other replacement faster sharp rise in the number of annual retirement
brought a more serious environmental problems. Plastic is an important component
of household electrical appliances, according to the ratio in Table 4 estimated
that every year the resulting recycled plastic that can be at least 15 million
tons, If we take into account the Waste Electrical and communications equipment
that can be recycled plastic volume, the figure of about 20 million t. The main
components of recycled plastic polypropylene (PP), polystyrene (PS), polyvinyl
chloride (PVC), ABS and so on, the value of a larger recycling; while some
thermosetting plastics, polyurethane foam, glass fiber reinforced plastic
materials is relatively difficult to recover. Waste disposal of household
appliances and reasonable during the regeneration of recycled plastic is one of
its important aspects. Different home appliances products by supporting
different types of plastics, the same product manufacturers are used in
different types of plastics are not the same, and sometimes the same kind of
plastic and additives used in the functional master batch or a different
formula, which gives home appliance plastic recycling work to a certain degree
of difficulty should be taken seriously, and strive to be an efficient
recycling, to minimize environmental stress and waste of energy. Electrical and
electronic matching plastic parts are already used by more than 100 million
tons, in the industrial package, information, transportation, aviation and
aerospace fields are widely used, the product upgrading soon. With a large
number of these products gradually enter retirement, becoming an important
source of waste plastics. Manufacture of plastic auto parts The greatest benefit
is to reduce the vehicle weight, saving costs and processes to improve the car
some performance, the developed countries the average car with a plastic over
100kg, car is scrapped cars will bring plastic recycling of resources and the
right Environmental and reasonable deal with problems. According to
authoritative auto industry experts predict that in 2005 China's auto output
will reach 5.7 million in 2006, the total demand for cars will reach 6.5
million. The average use of automotive plastics in China reached 70, the annual
consumption of more than 40 million tons. Automotive plastic varieties: PVC, PP,
PE, PU, ABS, PA, POM, etc.. As the car is scrapped the amount increased year by
year, automotive plastics and appliances, and electrical and electronic
plastics, like the amount of the steady increase in its recycling of waste
plastics using the same sources as the focus of treatment is similar in
principle. By 2010, China's automotive plastics need to use will be around 80
million tons. Therefore, scrap automotive plastic parts, recycling will become
increasingly difficult for the task.
