The answer to “which way is the best way of processing waste tyres?” depends on a wide range of factors. Firstly you should have a pretty good idea of the market demand in your area.

For example, it would make little sense to set up a cryogenic plant and produce fine rubber powder if the demand in your area is mostly for coarser rubber granules.  

Examples of use are: Tiles and tile adhesives, mixing with asphalt, sports surfaces, carpet underlay, noise and vibration insulation, playgrounds and matting. Simply selling crumb is not a very viable business as the market is very limited.

There could also be some particular circumstances at your location that may favour one specific technology and impede another.

Most of the recycling processes require large capital costs.  A recycling plant can cost anything from R20 million to R250 million. Thorough market research and prudent technology selection are the two key factors to success in this industry.

Only after you have decided what products you intend make, should you approach the question of technology selection.
