St. Cloud Zeolites are natural, inert non-toxic substances that are federally classified as GRAS (generally regarded as safe) and exempted from most regulations and reporting.

In addition to being used in a wide variety of commercial applications, St. Cloud Zeolite has been a useful tool in many environmental remediation and water treatment projects, including the treatment of radioactive waste associated with the Fukushima Daiichi nuclear accident in 2011.
