Compost Certification

Compost STA Certified



US Composting Council Seal of Testing Assurance

Our compost is STA Certified by the U.S. Compost Council as compost derived from curbside residential green waste. It is fine coarse screened to 3/8’’ minus. The Seal of Testing Assurance (STA) Program helps you make the best decision for your application by providing the 3 C’s:

Clarity –  
Similar to a nutrition label, the STA Program’s Compost Technical Data Sheet (CTDS) includes test results, a list of ingredients, and recommended directions for use.

The STA Program provides checks and balances within the STA Lab and Participant network to ensure proficiency and consistency with testing procedures and compliance, providing apples to apples comparisons of compost properties.

Similar to trusting a vehicle history report when purchasing a vehicle, the STA’s CTDS report provides consumers with confidence and knowledge of what is in the compost and how it was produced.
