Ahlstrom launches Ahlstrom ECO™, a renewable lignin-based automotive filter media

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.

Ahlstrom is partnering with Tecfil, a leading automotive filter manufacturer in Latin America, who is incorporating Ahlstrom ECO™ solution into a final filter design. The new product will be launched at the Automec exhibition in Sao Paolo, Brazil on April 25-29.

Paper Excellence Partners with Cumberland Wood Products to plant 1,000 tree seedlings with Cumberland House Cree Nation

Paper Excellence recently partnered with Cumberland Wood Products (CWP) to plant 1,000 jack pine seedlings in and around the First Nation community of Cumberland House. Cumberland House Cree Nation formed CWP to provide economic benefits directly to the communities and shareholders who remain stewards of Kitaskīnaw, the Saskatchewan River Delta. This spring, using seedlings facilitated by Paper Excellence through its partnership in Meadow Lake, CWP managed the plant with several volunteers from the community on May 27 and June 3. The jack pine is native to Saskatchewan and produces excellent habitat for local plant and animal species. The seedlings planted this year will provide a natural ecosystem buffer for key areas around the Northern Saskatchewan community, and serve to naturally enhance the regrowth on reserve.

Promising future for the Tasman mill and Nature’s Flame

The Tasman mill has over the last period commenced production of paper for supplies into the Asian packaging markets in the form of Pulp on Reel. This is part of the ongoing strategic development process to transition the Tasman mill in New Zealand out of standard newprint production. As part of the same strategic review, Norske Skog has received significant inbound interest for Nature’s Flame pellets facility located close to the Tasman mill; therefore, Norske Skog has decided to launch a process to asses the best long term ownership structure for this operation. “The Tasman mill management and the larger Australasian organisation have shown entrepreneurial spirit in quickly developing an alternative business case for the mill, making good commercial use of existing assets and infrastructure on the site. I am certain that the continuing work will result in further ways to maximise the potential in the Tasman mill’s excellent fiber access and fiber processing competencies” says Norske Skog Chief Executive Officer, Sven Ombudstvedt.
