    Biodegradable Plastics Based on Cellulose Acetate: Journal .

    Oct 23, 2006· In principle, cellulose acetate with such a degree of substitution is biodegradable, although degradation proceeds extremely slowly. However, when common plasticizers are substituted by specific esters and other low molecular components (at least 30% by weight), the "plastic material" has the same thermoplastic properties but will decompose in soil or water within just a few years.

    Cigarettes Butts and the Case for an Environmental Policy .

    May 20, 2009· Cellulose acetate is photodegradable but not bio-degradable. Although ultraviolet rays from the sun will eventually break the filter into smaller pieces under ideal environmental conditions, the source material never disappears; it essentially becomes diluted in water or soil [ 10, 11 ].

    Abstract. Microorganisms were able to extensively degrade cellulose [1- 14 C]-acetate (CA) with DS ranging from 1.85 to 2.57 over periods of 14–31 days. More than 80% of the original 14 C-polymeric carbon was biodegraded to 14 CO 2 for CA substrates with a DS of 1.85. CA polymers with a DS of 2.07 and 2.57 yielded over 60% conversion to 14 CO 2.

    ORIGINAL PAPER - Springer

    Cellulose is readily biodegraded by organisms that utilize cellulase enzymes, but due to the additional acetyl groups cellulose acetate requires the presence of esterases for the first step in biodegradation. Once partial deacetylation has been accomplished either by enzymes, or by partial chemical hydrolysis, the polymer's cellulose backbone is readily biodegraded.
