Estimates put forward during the European Tyre Recycling Association (ETRA) Conference 2007 in Brussels suggest that at least 300 million tyres reach their end-of-life each year throughout the EU’s 27 member states, with similar amounts found in North America, Latin America, Asia and the Middle East. Taking all of these regions collectively it is likely that the equivalent of more than one billion passenger car tyres require scrapping each year, and in the past many of these were destined for landfill or otherwise illegally dumped.

With EU directives banning the stockpiling of tyres or their disposal in landfill alternative methods of processing end-of-life tyres have been sought, however ETRA have reported that only a third of these tyres are being recycled into recovered materials, the bulk of them instead burnt as a fuel source. The results of conducting pyrolysis on scrap tyres have not in the past achieved promising results, with the resultant carbon being high in ash content and therefore only suitable for low-grade uses.
