Adsorbi funding news – Climate Tech Startup Adsorbi Secures €1Millon in Funding

The funds will help build and run a pilot plant in Gothenburg, develop new products, and expand its customer base. Even though the company is only three years old, Adsorbi has already gained a growing number of customers and industry partnerships.

Niklas von Weymarn, CEO of Metsä Spring said, “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,".

In October 2024, the European Union (EU) approved a new Ambient Air Quality Directive to improve public health by setting stricter air quality standards for pollutants like particulate matter (PM10 and PM2.5), nitrogen dioxide, and sulfur dioxide, which are known to cause breathing problems. The new limits, to be met by 2030, will align EU standards more closely with the World Health Organization (WHO) guidelines, pushing businesses to develop better air filtering solutions.

The World Health Organization reports that indoor air pollution caused over 3 million deaths in 2020. Poor air quality can lead to conditions like asthma, heart disease, and lung cancer. Since people in developed countries spend up to 80–90% of their time indoors, maintaining good air quality is essential for their health.

Adsorbi's high-performance material, made from Nordic tree cellulose, is designed to capture pollutants like nitrogen oxides (NO and NO2), acids, and aldehydes, which are major contributors to air pollution.

Aldehydes are found in items like cosmetics, perfumes, cleaning products, air fresheners, and grooming products. Adsorbi's patented material can be used in air filters, odor-removal products, and even in museums to protect artifacts and artwork from air pollutants.

Unlike the standard activated carbon, Adsorbi’s material lasts longer, doesn’t release harmful chemicals back into the air, is both water- and fire-resistant, and changes color to show when it needs replacing.

Adsorbi is also more energy-efficient, producing about 50% less CO2 – 3.5 kg CO2 per kilogram of material – compared to activated carbon, which produces 7.5 kg CO2 per kilogram.

Hanna Johansson, CEO of Adsorbi said, “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,”.

About Adsorbi

Adsorbi is a research-driven company that started at Chalmers University. Its innovative material was initially developed for art conservation through research at the Department of Applied Chemistry and the EU-funded APACHE project. This project aimed to use chemistry to find long-term solutions for preserving art.
