Estuarine biodegradability, assessed using the OECD 301F test, showed that EcoFLEXY fulfilled the 60% biodegradability requirement within 28 days of testing under the given aerobic conditions.

Soil biodegradation testing demonstrated EcoFLEXY significant biodegradation exceeding 90% according to both French (NF T 51-800) and Australian (AS 5810) home compostability standards. Visual inspections and analyses confirmed advanced biodegradation, meeting the criteria for compostable materials.

Marine biodegradability testing, performed according to ASTM D6691, demonstrated that EcoFLEXY readily biodegraded in seawater. After 28 days, 82.0% ± 0.0% absolute biodegradation was observed, surpassing the 70% validity requirement and reaching 97.5% relative biodegradation. This fulfills the general requirement of 90% absolute or relative biodegradation for satisfactory results.
