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.
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.
Ahlstrom ECO™ has been selected as the winner of Product of the Year-award by American Filtration Society (AFS). Click here to read more on the award.
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.
