EcoSummit preview: ‘None meet ASTM standards for biodegradability’

More from Eddie Gomez on his EcoSummit presentation:

“The amount of carbon in various commercially available bioplastics and natural fibers converted to CO2 (and methane) was determined during soil incubation, composting, and anaerobic digestion.” (The materials included biopolymers made from corn starch and polylactic acid; natural fibers such as coconut coir; and conventional plastics amended with additives claiming to confer biodegradability.)

“Although certain biopolymers and natural fibers appear to biodegrade to an appreciable extent, none meet ASTM standards for biodegradability or compostability.

“Conventional plastics containing additives did not biodegrade differently than non-additive-containing plastics.”
