Shredding and grinding tires: By shredding, the volume of scrap tires can be reduced to about ¼, thus reducing space requirement and shipping costs. Tire shredding can be considered a mature technology now in North America. Products: Rubber Crumb (sellable product – serves as raw material to many many industries) Finer synthetic and natural rubber (obviously after treatments) which can be used in Tiles and tile adhesives, mixing with asphalt, sports surfaces, carpet underlay, noise and vibration insulation, playgrounds and matting. Rubber crumb is also used in new tyres, devulcanisation for low-tech pressed or extruded rubber products, commercial flooring, traffic control products and plenty more.

Products: - Pyrolysis olf – Can be used a bio diseal - Carbon Black – Can be used in industries or to generate electricity. - Can be used as an alternative to Land Filling (which is banned in UK now) Molectra process: http://www.abc.net.au/newinventors/txt/s1300273.htm#otherinfo2 How does it work? The Molectra process integrates mechanical, chemical and microwave treatments to cleanly and efficiently break the tyre down into its base materials – oil, carbon, rubber granules, steel and plastic fibres, which can then be made into valuable products and resources. The Process: 1. The first step of the process mechanically removes the two steel beadwires intact from the rim of the tyre. This high quality wire can be cut into small pellets suitable for sandblasting shots. The tyres are sliced into 4-12 segments depending on tyre diameter, eliminating the need for energy-intensive shredding equipment. 2. Next the tyre segments are chemically treated for 4 hours in a blend of softening agents including the oil that is extracted from the tyres in the last stage of the process. This dramatically softens the rubber component of the tyre segments. Another important benefit of this chemical treatment is that it cleans the rubber particles by removing dirt and other contaminants prior to removing the oil. This step actually facilitates the separation of the components unlike
