Questions & Answers
What does the EPA mean by Biodegradable?
The term biodegradable as used by the EPA means capable of decomposing under natural conditions.
Why is ASTM D5511 chosen as the test method for biodegradability?
The ASTM D5511 test method resembles some of the conditions in biologically active landfills where the gas generated is recovered and biogas production is even actively promoted.
What is an ASTM D5511 test method?
The ASTM D5511 test method permits the determination of the rate of degree of biodegradability of polymeric products when placed in a high-solids anaerobic apparatus. The test is expected to resemble the environment of a high-solids anaerobic digestion process operated under optimum conditions.
This method involves measuring the volume of carbon dioxide and methane generated over time from the test sample relative to a positive control (typically cellulose), and a negative control (standard adhesive), and the inoculum alone. The rate and amount of carbon dioxide and methane generated as a portion of the total carbon input to the process is a direct measure of the amount of carbon containing substrate being utilized by the inoculum (percent biodegradation).
An increase in the input carbon consumed and/or the biomass generated during a test under ASTM D5511 in a given time relative to the negative control indicates whether there is an enhancement of the biodegradation of the adhesive.
