In 2010 December, promulgated by the Ministry of industry and information technology of the "guidance" of comprehensive utilization of waste tire pointed out that with the rapid development of national economy and the people's living standards gradually improved, China has become the rubber resources consumption country. At present, China's average annual rubber consumption accounted for 30% of the total world consumption of rubber, rubber product industry in China each year required more than 40% more than 70% natural rubber, synthetic rubber need to be imported, the contradiction between supply and demand is very conspicuous, rubber shortage of resources influence on national economic development appears day by day.
The "opinions" also pointed out, is the main Chinese tire rubber products. In 2009, about China tire rubber production consumption has accounted for 70% of the total rubber consumption of resources, annual production of waste tire 233000000, weight about 8600000 tons, equivalent to about about 3000000 tons of rubber resources, if all the recycling, the equivalent of Chinese natural rubber output of 5 years.
Reclaimed rubber refers to waste rubber through crushing, heating, mechanical processing and other physical and chemical processes, the elastic state into a plastic and viscous, can be vulcanized rubber. Easy to produce "three wastes in the production process".
On June 27th morning 11 when, the test base in Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd, the machine conveyor belt is pouring down the recycled rubber particles just out of the oven, the company chairman Wang Shijun hand then twists, the Ministry of industry and information technology energy saving and Comprehensive Utilization Department Deputy inspections officer Huang Jianzhong said: "you see, no foul the scene in the workshop, rubber smell out very small."
In 2014 May, the company elected to the national Ministry of industry and information announcement in line with industry access conditions enterprises list (first batch); June 27th afternoon, a "energy saving and environmental protection type waste rubber series cooling dynamic desulfurization waste new technology" in the company through the identification of scientific and technological achievements of China logistics and purchasing organization of joint.
Wang Shijun at this time the mood is good, he says to the reporter: "environmental protection is the first big problem in our industry, can not solve the problem, only the industry a dead end."
The reclaimed rubber industry development environmental protection block
Waste steel, waste plastics, waste paper, waste household appliances, scrap cars, discarded tires...... These are known as the "waste" the character of garbage, with circular economy view, is actually misplaced resources, is to be two times the development of city mineral.
In June 27th, the reporter with the Chinese tire renovation and Recycling Association to Qiangwei research group, President Zhu Jun says to the reporter, the use of recycled rubber scrap tire production is currently the main way China treatment of waste tire. In 2010 October, the Ministry of industry and information issued "tire industry policy" proposed, reclaimed rubber is the "three plastic" (natural rubber, synthetic rubber and reclaimed rubber) one of the first clear the raw material status, reclaimed rubber in the tire industry in.
According to the introduction, the 70's of last century, due to environmental requirements continuously improve, reclaimed rubber product quality and the production of pollution and other problems difficult to solve, the overseas developed country reclaimed rubber production atrophy. The reclaimed rubber industry the rise of China is forced out of the economic and social situation. At present, whether from the production scale, product variety and production technology, product quality, production equipment, China has become the most developed country reclaimed rubber industry in the world. In 2012, China reclaimed rubber output reached 3500000 tons, accounting for more than 80% of the global total output, has for 30 consecutive years ranked first in the world.
With the rise of China reclaimed rubber industry, especially to solve the waste rubber, waste tire recycling resources pollution caused the enormous economic and social benefits, promoting employment obvious effect of the international community to re understanding of reclaimed rubber, USA and some European countries began to explore, trying to break the bottleneck of the reclaimed rubber industry of environmental protection.
