Ahlstrom ECO™

Ahlstrom ECO™: a new choice for filter manufacturers

Filter media utilizes a lignin-based impregnation, which limit the usage of fossil-based resin

Ahlstrom ECO™ has the potential to reduce the carbon footprint of filter media

Ahlstrom ECO™: A new generation of lignin-based materials for transportation filtration

Transportation filtration world is facing certain sustainability challenges and Ahlstrom is currently working to address them by:

Ambitious emissions reduction program at all our plants (CO2, water, waste etc)
Improvement of end customers footprint (enhanced performances, support transition to electrification)
Adoption of more sustainable resources* (PFAS ban, formaldehyde reduction, fibers and binders)

Ahlstrom ECO™ is a technology supporting the increasing sustainability demands towards the global transportation market and offering a new choice for filter manufacturers.

Developed by Ahlstrom, a new renewable and sustainable filter media utilizes a lignin-based impregnation, limiting 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.

Ahlstrom ECO™ can be applied to a wide range of air and liquid filtration media, especially for transportation applications. Read more about Ahlstrom's filter media for liquid and air applications

According to our initial estimates¹, 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%, of formaldehyde emissions during the curing process.

Lignin is one of the main component of wood and the second most important bio-polymer on Earth after cellulose.

Lignin is a renewable side-product of wood pulp production which has been valorized at an industrial scale only recently.

*Engine air/oil/fuel filter media are typically made by wet-laid process combining cellulose and often polyester fibers, with a phenolic solvent-base saturation.
