Finland's Ahlstrom launches sustainable filter solutions

Developed by Ahlstrom, a new renewable and sustainable filter media utilises lignin-based impregnation, replacing fossil-based resin. The resin solution contains a significant amount of bio-based, renewable lignin, whilst the mechanical properties and the durability of the filter media, even in challenging environments, are maintained. 

According to Ahlstrom's initial estimates, the new lignin-based impregnated filter media displays a lower carbon footprint than a standard fossil-based resin media. Additionally, the lignin-based impregnation recipe brings a significant reduction, between 50-70 per cent, of formaldehyde emissions during the curing process. 

Ahlstrom is partnering with Tecfil, a leading automotive filter manufacturer in Latin America, who is incorporating Ahlstrom Eco solution into a final filter design. The new product has been launched at the Automec exhibition in Sao Paolo, Brazil.

"Ahlstrom Eco is a perfect example of how we are living up to our purpose to purify and protect with every fibre for a sustainable world, and our commitment to innovate fibre-based specialty solutions to our customer's needs and to help them solve some of the global challenges,” said Tamara Quatrano, VP, R&D, and product development filtration.  "We are pleased with the joint activities with Tecfil and proud to be able to offer this new, renewable solution to the market.”

"An outstanding collaboration between our two teams – Ahlstrom and Tecfil – resulted in a new, environmentally friendly filter solution.  We are proud to say that the combined efforts, especially from our engineering and testing group, have made it possible to bring this sustainable solution to the global market.  Not only is the product eco-friendly, but also performs on the same high standard as all our product lines,” says Flavio Montanari, industrial director Tecfil.
