Using tires for materials recovery results in the production of rubber granulate, textile, steel and rubber chips. They are also used to make products such as rubber flooring for playgrounds, paths, walkways and running tracks.
Rubber granulate is used in bitumen mixtures for asphalt and in making artificial turf for soccer fields, floor coverings, wheels for dumpsters and garbage cans.
The steel obtained from tires is a raw material used in steelworks and the textile is used by cement factories for energy recovery. Waste tires are also an excellent source of energy and can be used to make fuel with excellent properties.
The business and research sectors have taken a step further with the aim of using recycled rubber floor coverings for a cleaner environment.
The Varaždin-based Faculty of Geotechnical Engineering and Gumiimpex, the only Croatian company that uses waste tires for materials recovery, have been implementing a research project called “Recycled rubber and solar photocatalysis: Ecological innovation for passive air and health protection”.
The project, funded by the EU, is aimed at designing a product that will use natural processes – solar energy and photocatalysts – to eliminate organic air pollutants in urban areas.
A professor at the Faculty of Geotechnical Engineering, Aleksandra Anić Vučinić, notes that using recycled rubber floor coverings in the future would make the environment cleaner.
There are three tire recycling companies in Croatia – Gumiimpex – GRP, which uses waste tires for materials recovery, and the cement factories Holcim Croatia from Koromačno and Nexe from Našice, which use tires for energy recovery.
The system of waste tire recycling in Croatia was established in 2006, and it has been organised by the Environmental Protection and Energy Efficiency Fund.
In 2020, 28,480 tonnes of tires were put on the Croatian market. As much as 88% (25,066 tonnes) of waste tires were collected, and of that amount, 83% was processed, with 96% of the processed tires having been used for materials recovery and only 4% for energy recovery.
