Adsorbi, a startup specializing in cellulose-based air purification technology, has successfully raised €1 million in funding. The investment comes from Metsä Spring, Chalmers Ventures, Jovitech Invest, and includes a grant from Sweden’s Innovation Agency.
The funds will be used to build and operate a pilot plant in Gothenburg, develop new products, and expand Adsorbi’s customer base. Although the company is only three years old, it has already established a growing clientele and formed partnerships in the industry.
In October 2024, the European Union adopted the Ambient Air Quality Directive, which aims to protect public health by enforcing stricter standards for key air pollutants. This change has triggered a rush among businesses to find innovative air-filtering solutions.
Adsorbi’s unique material, made from Nordic tree cellulose, is designed to target pollutants such as nitrogen oxides and aldehydes. This makes it suitable for various applications, including air filters, odor-removing products, and even museum preservation.
The company claims that its material outperforms traditional activated carbon. It is longer-lasting, does not emit harmful volatile organic compounds, and is resistant to water and fire. The material also changes color when it needs replacing, making it user-friendly.
Moreover, Adsorbi’s product is more energy-efficient. It produces around 50% lower CO2 emissions compared to activated carbon. Adsorbi’s emission factor stands at 3.5 kg CO2 per kilogram, while activated carbon measures 7.5 kg CO2.
Hanna Johansson, CEO of Adsorbi, expressed appreciation for the investors’ continued support. She emphasized that establishing pilot production is crucial for scaling operations, as demand for effective air pollutant control continues to grow across various markets.
