T2O and the environment
Used tires for cars, trucks and industrial machines are being scrapped in millions every year. As the number of private vehicles increases rapidly, the number of scrapped tires also increases. Tires have a very high caloric value - a lot of energy. Hence, it has been used as a fuel in many industries, in particular cement factories. A lot of research has been made to allow used tires to be recycled into new tires but it has not been possible to succeed. Granulate from used tires can only be reused for low-quality products such as rubber blocks for playgrounds, bases for signs etc. Granulate is used in artificial soccer pitches or as an additive to road materials.
However, whether granulation, incineration, production of low-value products or open landfills they are not solutions that respect the environment. Granulation is an expensive and energy consuming process with a lot of CO2 emissions. Incineration results in a variety of dangerous emissions that are expensive and difficult to clean and only provides a fraction of the energy that was used to produce the tire in the first place.
