Recycling of old car tires

Despite the best efforts of modern science, the tires of your car rarely stop as long as you park your car. Someday they will wear out or deteriorate and you will have to replace them. Many years ago, most people changed their tires themselves. At the time, old tires were a nightmare. Almost all of them were banned from city dumps and dumps. Many people who had no other choice threw their old tires into a roadside ditch at night when no one was looking. Several companies that are willing to take your old tires often burn them. Burning tires is an environmental disaster in almost every sense of the word. When a car tire is burned, arsenic, mercury, cadmium, lead, beryllium, chromium and other toxic and carcinogenic substances, dioxins, are released into the air. Heart disease and respiratory problems can also be caused by metal particles coming out of the burning tire. In addition, the natural resources involved in the production of the tire are wasted if the tire is burned.

Today all this has changed. It had to change, there really was no other option. It is estimated that 1.3 billion tires are sold each year, and more than two-thirds of these tires replace old tires. This means that about 1 billion tires are thrown around the world every year. Whereas 20 years ago only 10 percent of tires were recycled, today more than 80 percent are sent to recycling facilities. Recycling old tires is a good idea no matter how you look at it, and literally hundreds of programs have been developed to recycle old car tires.

Almost no one changes their tires, and recycling of old tires is generally done by professionals who do it in an environmentally safe way. When you pick up your car to change tires at a local garage or tire store, there is almost always a guarantee to recycle your old tires. Approximately 1 in 4 of these old tires are recycled and reused in another vehicle. In many parts of the world, old tires are ground and used to make or grind rubberized asphalt for highways, and are used as a base for gravel roads or as a sand or gravel substitute in some other road construction programs. Some old tires are cut and used as part of the surface for indoor tennis courts or other indoor sports fields. For many applications, recycling old tires is cheaper than collecting and recycling new tires.

Tire burning has not been completely eliminated, but it has improved to the point where it is both environmentally safe and recyclable. The raw material is recovered and recycled using a process called pyrolysis, which burns the tires in a reduced air environment or vacuum. A typical passenger car tire will produce one kilogram of steel, four liters of oil, about four kilograms of carbon, and 850 liters of reusable combustible gas as a result of this recycling process.
