Large waste problem
Used tires are among the largest and most problematic sources of waste today, due to the large volume produced and their durability. During the end of the last century, and during the beginning of this, the European Union legislated on landfill to reduce the negative effect it has on the environment (the Landfill Directive 1999/31/EC). Later on they also legislated more specifically upon using complete and shredded tires as landfill (2000/53/EC). This naturally had a great impact on the tyre recycling industry in Europe, and the rest of the world, and many new opportunities have been created for tyre scrap.
Each year about 1.5 billion tires are sold world wide, which means that about as many are discarded. According to the European Tyre and Rubber Manufacturers Association (ETRMA) the recovery rate for End of Life Tires are about 95 percent in EU27, Switzerland and Norway, 89 % in the US and 91% in Japan.
A recycled tyre is separated into rubber (approx. 60%), fabric (approx. 20 %) and steel (approx. 20 %). In the above mentioned these regions about 7,336,800 ton End of Life tires are recovered each year – i.e. about 4,402,080 ton rubber and 2,934,820 steel is recovered.
Those same characteristics which make waste tires such a waste problem also make them one of the most re-used waste materials. As the rubber is very resilient, it can be reused in other products. The materials that are the outcome of tyre recycling have many benefits (as the flexibility, strength and combustibility).
Entire or shredded tires can be used for coastal protection projects and reinforcing embankments alongside roads. Because of its noise reducing benefits it is also useful on rain and tram tracks to reduce noise and vibrations. Another popular application for the rubber is in shoe soles, shock absorbers and shock absorbing mats.
Applications for powdered rubber are for example wheels (for dustbins, wheelbarrows, lawn mowers), artificial floor covering for sports arenas, flooring for stables and other protective floor (for schools, playgrounds etc) and rubber modified asphalt for road surfing (added for enhancing longevity and noise reducing).
Eldan Tyre Recycling
The idea behind the Eldan recycling equipment it fairly simple – downsize the material enough to be able to separate the various materials.
The technique behind the Eldan recycling equipment is not as simple – it has been developed since the company started in 1956. The first entire tyre plant was sold in the beginning of the 1990’s. Since then we have sold about 250 entire tyre recycling plants, and has become one of the leading names within tyre recycling.
With the Eldan tyre recycling equipment you will be able to process whole car and truck tires (including super singles) without prior debeading being required. You can also process earth mover tires, OTR etc.
The tyre recycling systems offered by Eldan is modular systems enabling you to invest as much or as little as you wish in the certain confidence that it will always be possible to add to the system as required. The flexibility of this modular approach means that a large number of combinations can be obtained ranging from a single machine for shreds or chips to a complete system for granules.
The Eldan plants are Multi-Size-Plants which mean that it is merely a question of changing the screen combination in the machines, should you wish to produce a different output size. The size requirements for the rubber/crumb market vary a lot, which is why it is so important to get a Multi-Size-Plant.
