Oxo-Biodegradability and Biodegradability

Deux documents récents à partager avec vous…

Le premier publié dans Bioplastics Magazine (01-09, Vol.4). Il s’agit d’une revue sur les plastiques biodégradables : Sorting Through Facts and Claims.

Biodegradability is an end-of-life option for single use disposable, packaging, and consumer plastics that harnesses microbes to completely utilize the carbon substrate and remove it from the environmental compartment – entering into the microbial food chain.

-

Le second, publié par le Biodegradable Products Institute (BPI). Il s’agit d’un condensé des commentaires du BPI concernant les additifs biodégradables utilisés pour accélérer la « biodégradation » des plastiques pétrochimiques : Background on Biodegradable Additives.

Testing has shown that in arid climates with sunlight and high heat, oxo-biodegradable additives will accelerate the fragmentation of traditional polymers. Data has shown that fragmentation can be achieved in 2 to 3 months. However, fragmentation is not a sign of Biodegradation and there is no data to show how long these plastic fragments will persist in the soils or marine environments. Further, data has shown that moisture will retard this fragmentation process for months or longer.
