Crumb Rubber (Tire-Derived) High Risk

Ground-up recycled tires used as infill in artificial turf, playground surfaces, and some flooring products. Contains a complex mixture of chemicals accumulated during the tire's life and from its original manufacture.

Health Concerns

  • Contains multiple carcinogens including PAHs and benzene
  • Heavy metals including lead, cadmium, and zinc
  • Phthalate plasticizers
  • Volatile organic compounds that off-gas, especially in heat
  • Processing oils with hazardous additives
  • Potential skin contact and ingestion exposure, especially for children

Environmental Impact

  • Zinc leaches at levels toxic to aquatic life
  • Microplastic pollution - 1-4% of infill lost annually from turf fields
  • PAHs and heavy metals contaminate soil and groundwater
  • Heat islands from dark surfaces increase chemical release
  • Cannot be safely recycled at end of life

Regulatory Status

EPA and state agencies continue studying health effects. EU REACH has proposed restrictions. Some municipalities banning new installations.

What to Avoid

Artificial turf with crumb rubber infill, rubber playground surfaces, rubber mulch in gardens, any interior rubber flooring from recycled tires

Safer Alternatives

Natural grass, cork or coconut fiber infill for turf, wood fiber playground surfaces, virgin rubber or TPO flooring
