Biodegradable cellulose acetate receives marine biodegradability certification

Osaka, Japan-based Daicel Corporation has announced that its Cafblotm product obtained the OK biodegradable MARINE, an international certification for marine biodegradability, in August 2021. This is the second such validation following the granting of the “OK compost INDUSTRIAL” certification for biodegradability in an industrial composting plant.

Cellulose acetate is a naturally-derived, biodegradable, eco-friendly material

Cellulose acetate is a naturally-derived, biodegradable, eco-friendly material manufactured from plant-derived cellulose and naturally occurring acetic acid. After disposal, cellulose acetate biodegrades into water and carbon dioxide in its final stages. Moreover, because it is made mainly from non-edible ingredients, it will have no negative effect on future food production.

By applying the cellulose chemical technology, developed over many years, Daicel has devised a molecular structure that facilitates biodegradability. As a result, our new product Cafblotm exhibits an enhanced biodegradation rate, especially in seawater, while maintaining the same quality as conventional products.

The large amount of plastic waste generated today contributes to marine pollution and the destruction of marine ecosystems. In recent years, the negative impact of such pollution on ocean fisheries and concerns for human health have become major social issues. The company said it is helping to provide a solution to this problem by promoting the widespread adoption of cellulose acetate, particularly Cafblotm.

Cellulose acetate is a material widely used in common products such as eyeglass frames, fibers, LCD protective films, and cosmetics. The addition of a plasticiser allows it to be thermoformed like other plastics. Going forward, Daicel will continue to collaborate with its partner companies and administrative entities to develop applications for conventional cellulose acetate and highly biodegradable Cafblotm cellulose acetate in products at risk of being lost or discarded in marine environments.
