Ahlstrom, a global leader in fiber-based specialty materials, enhances 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. Delivering superior filtration performance helps optimize equipment protection while contributing to a lower environmental impact.
Ahlstrom estimates that the lignin-based impregnated filter media displays a lower carbon footprint than a standard fossil-based resin media. Additionally, the lignin-based impregnation significantly reduces 50–70% of formaldehyde emission during the curing process. This makes the filter media an industry-leading choice for manufacturers seeking to improve sustainability without compromising performance or reliability. A flame-retardant version is also available for air filtration applications requiring enhanced fire safety.
