STA Certified
Independently Tested. Quality You Can Trust.
Hawaiʻi Organics Compost is proud to be one of three Hawaii-based compost companies participating in the U.S. Composting Council's Seal of Testing Assurance (STA) Program, one of the nation's leading compost testing and quality assurance programs.
​
Our compost is regularly tested by independent laboratories to verify product quality, consistency, and key performance characteristics.
What is STA Certification?
The Seal of Testing Assurance (STA) Program is administered by the U.S. Composting Council and provides standardized testing and reporting for compost products.
​
Through the program, participating compost manufacturers submit compost samples for routine laboratory analysis. These tests evaluate important characteristics such as:
​
🌱 Nutrient content
🌱 Green matter content
🌱 pH and salinity
🌱 Stability and maturity
🌱 Physical characteristics
​
The result is a transparent, science-based assessment of compost quality that helps customers make informed decisions.
Why It Matters
Not all compost is created equal.
​
STA testing helps ensure that customers receive a product that has been independently evaluated for consistency and quality.
​
Benefits of STA-certified compost include:
​
✓ Reliable product information
✓ Consistent quality from batch to batch
✓ Independent laboratory testing
✓ Greater transparency for growers, landscapers, and homeowners
✓ Confidence in what you're putting into your soil
Tested Right Here on Maui
Our compost is produced from Maui green waste and processed at our Waikapu facility.
​
By participating in the STA Program, we're committed to providing high-quality compost while helping divert green waste from the landfill and returning valuable nutrients back to local soils.
