With the rapid development of China's automotive industry, China has become the world's second largest tire producer, generating more than 112 million waste tires every year, or around 3.2 million tons. At the same time, the service life of tires is limited, and discarded waste tires are non-fusible or refractory polymer elastomeric materials, with strong resistance to heat, machinery and corrosion, and extremely difficult to degrade. They are extremely difficult to degrade and will affect the ecological environment and cause serious pollution for over a century. This "black pollution", if not dealt with early, will cause great harm to the environment.
Since the 1970s, in order to effectively eliminate "black pollution", countries around the world, especially in Europe and the United States, began to recycle waste tires and try to make fine rubber powder processing technology research and development. The fine rubber powder made from waste tires can replace part of the raw rubber, which is a precious secondary resource and is the best way to deal with "black pollution" in a harmless, resourceful and industrial way. In addition to being used in the production of rubber products such as tires, recycled rubber powder has a wide market in the fields of modified asphalt paving highways, railways and underground sleepers, sports tracks, leak-proof and impermeable materials, construction materials, rubber and plastic products.
In China, the annual consumption of raw rubber is 3.45 million tons, 60% of which needs to be imported, and since 2002 has surpassed the United States as the industry's largest consumer of rubber for three consecutive years. With the rapid development of the economy, the counter-constraining effect of resources on the economy is beginning to emerge and is becoming increasingly serious. A major challenge lies ahead. For this alarming malignant status quo, many domestic insightful people are constantly running to call for a solution to the problem of environmental pollution of tires, but also the huge waste tires into a renewable resource of economic sustainable development, in the country, the use of waste tires made of fine rubber powder has a very wide range of "potential "can be explored, its extended application and further deep processing will form a booming sunrise industry, become a new economic growth point, at the same time, will also bring a revolution in China's transportation, chemical, building materials and other related industries, the cost. To sum up, the waste tire recycling industry will have great market development potential, so the use of tire shredder processing rubber powder in line with the requirements of the sustainable development of the real economy.
