Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Test product Agrol® achieved 91.96% biodegradation. The product meets method requirements for Ready Biodegradability.
- Executive summary:
The ASTME 1720 -01 biodegradability testing monitors the degree of activity of microorganisms exposed to a material that is being tested for a biodegradable status. In the test, if the microorganisms recognize the material as a food source, then an increase in biological activity is observed through data collection specifically designed to assess biological conversion of organic carbon to inorganic carbon. If the material is not a recognizable food source or is toxic or inhibitory, then there is no measurable increase in biological activity or, in some cases, there is a marked decrease in activity relative to a biodegradable control.
Positive Control: Dextrose @10mg/L
Carbon Analyzer: High Sensitivity Shimadzu TOCvch
TIC Analysis Employed: Basified Aqueous Phase Inorganic Carbon via TOCvch
Test bottles were set up in triplicate for statistical validation of results,and a total of 9 sampling events were executed. The inoculum was preconditioned in the test medium via method guidance to remove organic carbon and inorganic carbon prior to testing. The inoculum source is the Escatawpa, MS municipal waste water treatment facility.
Based on the testing conducted in accordance with the specified method above, test product Agrol® achieved 91.96% biodegradation. The product meets method requirements for Ready Biodegradability.
The method classifies greater than 60% biodegradation within a 10 day window as Ready Biodegradability and greater than 60% biodegradation over 28 days without meeting a 10 day window as Ultimate Biodegradability.
