Adsorbi launches cellulose-based air purification material for the art industry

Adsorbi AB, a research-based startup originating from Sweden’s Chalmers University of Technology, has launched its first commercial product: a cellulose-based material that protects artwork and sensitive objects from degradation by air pollutants.

The adsorbing material, which is used to purify air in the storage and transportation of artwork, combines a long product lifetime with high security, making it ideal for museums and archives.

Adsorbi’s material is a bio-based and high-performing adsorbent. The cellulose originates from Nordic forests and the production is in Europe. The white material changes colour when it needs to be replaced, enabling optimised air purification.

"Our research stems from art conservation where paintings, artifacts, and other sensitive objects are exposed to air pollutants, such as VOCs, and undergo irreversible changes upon prolonged exposure. Most of the pollutants are emitted from the objects themselves, making air purification in all types of storage of art vital," said Dr Kinga Grenda, CTO and co-founder of Adsorbi.

Currently, air pollution in museums is either ignored or the adsorbent activated carbon is used. The problem with using carbon in this environment is its short product lifetime and the risk of staining objects in collections.

"We have developed a sustainable material tailored for capturing air pollutants in museums, galleries, and archives. Using the Adsorbi innovation as a base, we will soon launch new products for other industries in need of sustainable air pollution removal,” said Hanna Johansson, CEO and co-founder of Adsorbi.
