Ahlstrom introduces a new range of renewable and sustainable filtration solutions for automotive applications. Ahlstrom ECO™ is a technology supporting the increasing sustainability demands of the global transportation market and offering a new choice for filter manufacturers. Developed by Ahlstrom, a new renewable and sustainable filter media utilizes 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 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.
