Playful recycling
Liquid nitrogen assists in the crushing process used to recycle old tires. The cryogenic gas cools the tires to temperatures between minus 120 and minus 150 degrees Celsius, making them brittle. In that state, they can be readily crushed and even ground into a fine powder. The raw materials obtained in this way are used to manufacture products such as road construction material, artificial turf and floor coverings for sports fields and playgrounds.
