On April 26 was opened in the Madrid town of Valdemoro plant of Integral of recovery of rubber technology (Tirca), the only Spain that recycles tires used by cryogenic grinding. This technology, developed by metallic carbides, used liquid nitrogen to freeze the rubber, which facilitates its milling and the subsequent use of all the resulting materials. In Europe there is another plant, similar to Tirca, located in Germany, although his approach is less ambitious.
Tirca plant represents an important contribution to the resolution of the problem causing the used tires, since they can not be reused and its volume makes the burial an impractical option.
To solve the problems of the discarded wheels, until now used technologies of tear that required the use of energy and providing discrete results. Now, the technology developed by metallic carbides allows grind rubber with less energy and obtain the necessary granulometry, i.e. a great more thin or thicker on the basis of the use that you will be given.
Cryogenic grinding is based on the physical properties of rubber which, at normal temperature, is flexible and very durable. However, to 90 ° C or 100 ° C below zero, it becomes a rigid, fragile as glass and easily reducible material particle size.
