Biodegradable Certification

Description
This certifies that numerous plastic samples with specific “biodegradable content” have been tested by independent laboratories in accordance with standard test methods approved by ASTM, ISO and other such standardization bodies to determine the rate and extent of biodegradation of plastic materials.

Characteristics
A degradable plastic, per ASTM 1991, is one that is designed to undergo a significant change in its chemical structure under specific conditions resulting in a loss of some properties that may vary, as measured by standard test methods appropriate to the plastic and application in a period of time that determines its classification. A biodegradable plastic is one where the degradation results from the action of naturally occurring microorganisms such as bacteria, fungi, and algae.

Technical Info
Biodegradation of test samples used:

ASTM D5209-91, “Standard Test Method for Determining the Aerobic Biodegradation of Plastic Materials in the Presence of Municipal Sewage Sludge”

ASTM D5338.98, “Standard Test Method for Determining Aerobic Biodegradation of Plastic Materials under Controlled Composting Conditions” (equivalent to CEN prEN WI 261085 and ISO 14855 “Evaluation of the Ultimate Aerobic Biodegradability and Disintegration of Plastics under Controlled Composting Condition”)

ASTM 5511, “Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High Solids Anaerobic Digestion Conditions.”

Results from the tests and related biodegradation and ecological impact experiments in various environments certified that the specific biodegradable content products can be marketed as biodegradable and safe for the environment.
