In 2006 over 100,000 worn tyres were taken off cars, trucks and earthmover vehicles. About 70% of these tyres were recycled, 28% were added to landfill or stockpiled and created a major waste problem.
Piles of stockpiled tyres can present a fire hazard, even tyres in landfill sites can be ignited. Once started, these fires are difficult to extinguish and can burn for days as we often see in the news. Burning tyres give off some serious pollutants including water borne pollutants. Tyres in landfill sites can be unstable and tend to rise to the surface, creating potential fire hazards and limiting options for future land use.
