Ahlstrom is enhanceing its offering for its patented lignin-based filtration media. A proven, high-performance alternative to traditional filtration materials further supports customers in making sustainable choices.
Ahlstrom Eco, introduced in 2023, combines a proprietary lignin-based impregnation, replacing fossil-based resin with a renewable, bio-based cellulose filtration media. This innovation significantly reduces reliance on non-renewable resources while maintaining exceptional durability, mechanical strength, and filtration performance.
Designed for liquid and air filtration, Ahlstrom Eco is ideal for engine oil and engine air intake filtration, as well as for industrial filtration systems operating under challenging conditions. By delivering superior filtration performance, it helps optimize equipment protection while contributing to a lower environmental impact.
According to Ahlstrom’s estimates, the lignin-based impregnated filter media displays a lower carbon footprint than a standard fossil-based resin media. Additionally, the lignin-based impregnation brings a significant reduction, between 50–70% of formaldehyde emission during the curing process. This makes it an industry-leading choice for manufacturers seeking to improve sustainability without compromising performance or reliability. Additionally, a flame-retardant version is available for air filtration applications requiring enhanced fire safety.
"At Ahlstrom, we are committed to leading the transition to more sustainable filtration solutions," says Stephanie Pigeot-Rémy, Ahlstrom’s head of Global R&D and Product Development, Filtration. "Since launching Ahlstrom Eco, we have strengthened our expertise and production capacity, enabling us to better support our customers. Together, we are co-developing new solutions, ensuring that sustainability and high performance go hand in hand."
