 A peer-reviewed report of the work showed 91% biodegradation in a soil environment within 24 months, when tested in accordance with ISO 17556.OXO-degradation has been studied at the Eurofins laboratory in Spain, where on 25 July 2017 they noted 88.9% biodegradation in 121 days, and in many other laboratories around the world.OXO-degradable plastics have been degraded in real time in seawater at the Banyul laboratory in France.
