Recycled Rubber and Infill

The use of recycled rubber is becoming increasingly common as a sustainability practice across several industries.

Rubber infill is commonly used in playground construction, field turf, molded products, and rubberized asphalt, to name just a few. Recycled rubber can come from many different sources, so it’s crucial to carefully test all recycled rubber to ensure safety.
