What are the methods for recycling waste tires? What are their characteristics?

In recent years, we have been producing tires, but we have ignored the pollution problems caused by waste tires. Many tires are discarded randomly , causing serious soil and water pollution. Many experts call for us to recycle waste tires. Do you know what recycling methods are available for waste tires?

Piles of waste tires

At present, the recycling of waste tires mainly includes four methods: overall retreading, manufacturing recycled rubber, producing rubber powder and getting oil by pyrolysis. They all have their own characteristics. Let me introduce you in detail.

Method 1:Overall retreading

The overall retreading of waste tires is a process of partial repair, processing, re-applied and re-applied tread rubber, followed by vulcanization to restore its use value. Although this recycling method can prolong the service life of tires, in recent years, with the development of science and technology, the high-quality and low-cost synthetic rubber has made the tire retread market smaller and smaller.

Method 2:Manufacturing recycled rubber.

In this method, waste tires undergo physical and chemical processes such as crushing, heating, and mechanical treatment to make their elastic state become plastic and viscous rubber that can be revulcanized. The utilization rate of this recycling method is still very high, but it consumes too much energy, the process is too long, and the cost is too high, making the recycled rubber industry not our best option.

Method 3:Producing rubber powder

After a series of treatment processes such as ozone crushing, high-pressure blasting crushing, and low-temperature fine crushing of waste tires, rubber powder can be obtained. The rubber powder can be used as a filler for asphalt pavements. However, the cost of using tire rubber powder as an ingredient to produce road asphalt is also too high. So it is impossible to use in large quantities.

Method 4:Getting oil by pyrolysis

The waste tires are pyrolyzed at high temperature, condensed into oil, de-odorized and drenched to get pyrolysis oil, carbon black and steel wire. The entire pyrolysis process is carried out in a closed environment, which is safe and environmentally friendly, and the product has a wide range of practical uses. Because of its large processing capacity, no secondary pollution, and high resource recycling, the pyrolysis method is considered to be one of the best ways to deal with waste tires today.
