Biobased content
Biobased content is the most distinctive feature of cellulose acetate. The higher the biobased content, the higher the content derived from nature. It is critical important to our furture since fossil is Non-renewable resources.
The element carbon, 14C, has a naturally occurring isotope, 14C, which allows for a clear distinction between carbon based substances in present living organisms and carbon based substances from fossil sources. Due to its radioactive decay, it is almost absent from fossil products older than 20000 years. Consequently, if the 14C is present in chemicals, then it originates from recent atmospheric CO2. The 14C content may thus be considered as a tracer of chemicals recently synthesized from atmospheric CO2 particularly of recently produced bio-based products.
The most commonly used methods for testsing biobased content at present are ASTM D6866, ISO16620, EN16640.
