The recycling process starts out by gathering used or waste materials and they undergo a process to produce a new product.
The Nightmare Created by Old Tires
Decades ago, car owners would just dispose of their used tires on the side of the road or at the junkyard after they’ve replaced it with their new one. During those days, they gave a big headache to the people in-charge of recycling them because there were no methods available back then.
Some companies took these used tires away from the roads and abandoned areas but didn’t really recycle them. They just burned them. When these tires were burned they released pollutants like lead, mercury, and cadmium which were harmful to the environment and could potentially get into the water and air systems in the city. People who were unfortunate enough to be exposed to these toxic substances were at risk to respiratory and heart problems.
Recycling Car Tires Today
Recycling methods have improved and car-owners can dispose of their tires in a safer way. Tires sales were estimated to reach 1.3 billion purchases around the world annually. Nowadays, 80% of used tires are recycled by facilities in different countries which is a significant improvement from the 10% recycling rate back in the day.
There are currently hundreds of methods used to reuse and recycle car materials and its parts. A recent report has revealed that 1 in every 4 cars were fitted with a recycled, re-treaded tire used in another part of the world. Gravel road foundation and road construction are some of the new uses for used tires. They’re grounded, chopped, and substituted for materials commonly used in these activities. Indoor courts for tennis and others sports have been known to have used old tires as a component of the court surface.
The Latest in Tire Recycling: Pyrolisis
Some facilities still practice tire burning to dispose of old and used tires. But, the method they use is now a safer and more improved version of the previous practice. This process is named pyrolysis. It uses a technique where old tires are heated inside a closed, oxygen-free chamber keeping the harmful substances from leaking out. There is also a pyrolysis which uses an electromagnet to churn out by-products like oils, gases, carbon, and metal. This method is expected to yield 850 litres of gas, a kilo of steel, 4 litres oil, and 4 kilos of carbon from just one used car tire.
