Adsorbi: Eco-Friendly Cellulose-based Air Purification

Date:August 28, 2023

Country: Sweden

Application

• Air filters: Adsorbi's material is used in air filtration systems to capture pollutants and improve indoor air quality.
• Odour removal: The material is effective in eliminating bad odours in products like shoes, bags, and cars.

Description

Swedish startup Adsorbi has developed a cellulose-based air purification material made from sustainably sourced wood. The material captures and stores air pollutants, offering a more eco-friendly alternative to activated carbon. It has applications in air filters, odour removal products, and art conservation. Adsorbi's innovative solution aims to improve indoor air quality and reduce environmental impact.

Pathway Description:

The process begins by extracting cellulose from sustainably sourced wood, which is then processed into cellulose nanofibers or cellulose-based powder. These fibers are treated to enhance their adsorption capacity, making them effective at capturing air pollutants and volatile organic compounds (VOCs). The material undergoes a modification process to optimize its properties for specific applications, such as odor removal or air filtration. Finally, the product is incorporated into various applications like air filters, odor absorbers, and in museums for protecting artworks from air pollution.
