Crumb Rubber
Crumb rubber is ambiently manufactured from clean scrap tires that are ground into smaller uniform granular rubber of various sizes, and by removing the tire wire and fiber using magnets and air separators, respectively.
Depending on the application and end user’s specifications, the crumb rubber is classified by sifting screens. The crumb rubber is packaged in 2,000-lb poly-supersacks.
We produce two varieties of crumb rubber:
- All-Black-Rubber (ABR) from truck tires
- Ground-Tire-Rubber (GTR) from mostly passenger car tires
Crumb rubber is used in a variety of applications, including:
- Synthetic Turf Fields (Infill)
- Molded Rubber Products
- Rubber Flooring
- Equestrian Footing
- Animal Bedding
- Rubber-modified Asphalt
- Poured-in-Place Rubber Surfaces
- Running Tracks
- Roofing Materials
Our crumb rubber is tested for particle size distribution and moisture following specific American Society for Testing and Materials (ASTM) standards using state-of-the-art equipment in our on-site laboratory to ensure the products meet the end user’s specifications.
Furthermore, independent laboratories have tested our crumb rubber. The results indicate that PFAS were not detected above laboratory reporting limits using EPA Method 1633, total lead concentrations were well below the applicable limit in ASTM F2765, and concentrations of eight specified metals were well below the applicable limits established in ASTM F3188 and ASTM F3012.
Additional information regarding the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting our crumb rubber is provided on our Safety Data Sheet (SDS).

Commonly Asked Questions
What is the size of your crumb rubber?
BDS manufactures crumb rubber from whole scrap tires to custom sizes starting at 3/8″ to finely ground crumb rubber (30- mesh); the end-user’s specifications define sizing. Contact us to request a sample.
How is your crumb rubber produced?
Crumb rubber is manufactured from clean scrap tires that are ground into smaller granular rubber of various sizes using a series of shredders and a cracker mill and by removing the tire wire using multiple rare-earth drum magnets and removing most of the fiber using an elaborate fiber separator system. The smaller granular rubber from the cracker mill goes through a triple-deck screener, destoners (for stones, glass and non-ferrous metals), roll screen (for Kevlar removal, certain product sizes) and finishing screens simultaneously producing multiple-sized crumb rubber products. The screened rubber is conveyed to one of four bagging stations where the rubber is packaged in 2,000-lb poly-supersacks for shipment to customers.
Is your crumb rubber used in synthetic sports fields safe?
California’s Office of Environmental Health Hazard Assessment (OEHHA) released its final results in 2026 from a major evaluation of synthetic turf fields containing crumb rubber infill. The study concluded that there were no significant health risks for athletes, coaches, referees, spectators, or children using these fields. These findings build on evaluations conducted by the EPA, CDC, and CPSC in 2019 and 2024 and provide additional confidence in the safety of recycled tire-derived crumb rubber used in synthetic turf fields.
