Swedish climate tech startup Adsorbi, a research-based spinout from Chalmers University of Technology, has raised €1M in funding from Metsä Spring, Chalmers Ventures, Jovitech Invest, and a grant from Sweden’s Innovation Agency for its cellulose-based air purification material.
Adsorbi's high-performing material, derived from Nordic tree cellulose, is designed for pollutant capture, including key nitrogen oxides like nitric oxide (NO) and nitrogen dioxide (NO2) as well as acids and aldehydes. Its material will be used in air filters, products that remove odours, and in museums to protect artefacts and works of art.
The capital will be used to construct and operate a pilot plant in Gothenburg, develop new products, and grow its customer base.
In October 2024, the European Union (EU) approved the new Ambient Air Quality Directive. The directive prioritises public health by introducing stricter air quality standards for key pollutants, including particulate matter (PM10 and PM2.5), nitrogen dioxide, and sulfur dioxide – all known to cause respiratory issues.
“We’re grateful to our investors for their continued support. With the funding we will establish pilot production, a crucial step for scaling Adsorbi. Air pollutant control is needed in many markets, and we’re ready to offer a commercial solution that ensures the air we breathe is clean without extensive use of fossil-based materials,” said Hanna Johansson, CEO of Adsorbi.
“We joined Adsorbi’s journey 1.5 years ago. The company has achieved all the goals agreed upon at the time and even surprised us investors positively in a few areas. The plan for the company's next phase was very logical, and we are excited to support its implementation. Their development of a pulp-based new product makes them particularly relevant to Metsä Group’s mission. With Adsorbi in our portfolio, we move closer to replacing fossil-based materials in everyday applications," said Niklas von Weymarn, CEO of Metsä Spring.
