Tire rubber crumb contains a range of organic contaminants and heavy metals that can volatilize into the air and/or leach into the percolating rainwater, thereby posing a potential risk to the environment and human health. The major concerns stem from the infill material that is typically derived from scrap tires. However, there remains the question of whether it is an environmentally friendly alternative to natural grass.
