Following the Europe wide ban on disposing of used tyres to landfill, the problem of how to make use of scrap tyres has become a much more pressing issue. Estimates indicate that each year around 250,000,000 used tyres are accumulateid in the European Union, and consequently innovative ways of reusing them are urgently required. Therefore many research groups are considering ways in which rubber reclaimed from scrap tyres can be utilised as a raw material, to reduce the volume of virgin rubber consumed each year in Europe. One such project, funded by the European Commission was known by the acronym 'Criosinter'. The goal of Criosinter was to develop an innovative recycling process for producing rubber materials with enough quality to compete with virgin rubber in highly demanding products. This was to be achieved by integrating emerging tyre grinding technologies, new material transformation processes, various chemical additives, and new materials design technologies. It was found that incorporating approximately 2.5% sulphur into recycled tyre crumb yielded a sintered vulcanisate with improved tensile strength. Furthermore a cure time of just ten minutes was found to be necessary to achieve maximum tensile strength when sulphur is used as an additive.
