The rubber used in recycled rubber mats comes from tires, that incorporate a quantity of dangerous chemicals. In this article, read about the latest research concerning the safety of recycled rubber mats.
Many individuals have expressed concern about the use of recycled rubber. Recycled rubber arises from used tires, which many fear could harbor lead or other toxins. Concerns kicked into high gear during 2009 after the environmental advocacy group PEER (Public Employees for Environmental Responsibility) uncovered internal communications in the EPA that stated that this agency can't vouch for the safety of recycled rubber because there had not been enough studies done in those days.
So are recycled rubber mats unhealthy? Let's examine the facts.

are made from used tires that could otherwise end up in the waste stream. Used tires can sit in the landfill for thousands of years without breaking down. There, the tires can catch fire, leading to massive creation of toxic smoke. Tire fires are hard to extinguish, and tires can smolder in the stacks for a long time at a time. In open dumps, they turn into a breeding ground for mosquitoes, which spread disease.
Recycling tires into materials like playground mulch and rubber mats cuts down on number of tires that wind up in landfills by approximately 90%.
Rubber mats and mulch on playgrounds result in significant reductions in injuries as compared with wood mulch or concrete. According to one study, injuries were doubly common on wood mulch kitchens Boston MA surfaces and half a dozen times as common on concrete.

In outdoor playing conditions, however, field studies show that you can breathe easy understanding that your kids are safer with all the mats today.
