CDA, a natural polymer derived from plant cellulose, has been used in products such as eyeglass frames and cigarette filters for over a century. The team found that creating a porous structure of CDA using the “foaming” method accelerated its decomposition by 15 times compared to solid CDA.
In a 36-week experiment, foamed CDA lost 65−70% of its mass in flowing seawater, while foamed CDA remained intact. WHOI has partnered with bioplastics manufacturer Eastman, which currently produces biodegradable and compostable packaging pallets based on this technology.
