The specialised regenerated cellulose core film used in Bioglitter® represents more than 90% of its content and is certified compostable in both industrial (EN13432, EN14995, ASTM D6400, ISO 17088) and home composting environments (OK Compost Home) and also marine biodegradation approved to ASTM D6691-09. A small amount of surface coating is applied to the certified naturally biodegradable core during the manufacture of Bioglitter®. Irrespective of how little is applied and that the materials used are compliant, physical retesting to the appropriate standard/s is required to claim Bioglitter® is certified. Industrial composting is conducted in man made conditions c.60oC and high humidity. Whereas OK Compost Home and marine testing are more representative of the biodegradability in the natural environment. There is a significantly higher probability for glitter to be found in general waste, waste water and general outdoor environment after use. The route to industrial composting via the compost bin is highly unlikely in reality. Specific Bioglitter® testing; Standards can change, ASTM D7081-05 marine standard was withdrawn in 2014 and more recently attention has been drawn to the applicability of industrial compostability standards (EN13432, ASTM 6400) as a measure of compostability in the natural environment. Biodegradability testing to standards more appropriate to where glitter is found after use and more representative of the natural environment can take up to two years. Considering the above, our approach to testing to a particular standard will be based on its merits in terms of time, cost and validity for a particular glitter application. The goal being to obtain independent test data and certification validating the ability of Bioglitter® to biodegrade outside in the natural environment.
