Sustainable Filter Media with Lignin-Based Resin

Proven performance. Lower carbon footprint. Ready for your production line.

 

GESSNER’s lignin-saturated cellulose filter media is a next-generation solution for manufacturers seeking to reduce their environmental impact without sacrificing performance. By replacing fossil-based phenolic resins with renewable lignin, our media delivers the same high-efficiency filtration and mechanical strength - while cutting product carbon footprint by up to 6.6% and saving up to 100 kg of crude oil per ton of media.


Reduce your product carbon footprint

Our lignin filter media is designed to reduce your product carbon footprint. This cellulose filter media is saturated with an eco-friendly lignin-based resin, ensuring that your filter element offers best performance, while taking a step into more sustainable filtration solutions.

Our lignin-based resin technology enables a measurable reduction in your product’s carbon footprint.

  • Up to 6.6% CO₂ reduction (cradle-to-gate) in engine air filter applications
  • Saves ~100 kg of crude oil per ton of media
  • Verified using Sphera MLC 2024 data

Already in use by leading OEMs, this solution is proven in real-world filter production.

 


Sustainability without compromise

By adding the eco-friendly lignin saturation we developed a more sustainable product that does not compromise on filtration performance nor on its mechanical properties. Additionally, it decreases the formaldehyde emissions during the curing process.

  • Maintains OEM-grade filtration performance and mechanical durability
  • Compatible with existing filter production lines - no retooling required
  • Optional flame-retardant formulation available for high-temperature and safety-critical applications
  • Reduces formaldehyde emissions by up to 70% during curing

What is lignin?

 

Lignin is a natural, complex organic polymer found in the cell walls of wood and plants. It provides structural strength, rigidity, and resistance to decay - enabling plants to grow tall and transport water efficiently.

As one of the most abundant renewable biopolymers on Earth, lignin is increasingly used in sustainable materials, including eco-friendly filter media.


Why is lignin used in filter media?

 

Lignin is a sustainable, high-performance alternative to fossil-based phenolic resins traditionally used in cellulose filter media.
It offers:

  • Excellent stiffness, strength, and rot resistance
  • No negative impact on filtration efficiency or mechanical properties
  • Seamless replacement of phenolic resins without altering media performance

This makes lignin an ideal bio-based resin for manufacturers seeking greener filtration solutions without compromising quality.


Sustainable sourcing of lignin

 

Our lignin is responsibly sourced as a by-product of the paper and biofuel industries. No additional trees are harvested - ensuring that the lignin used in our filter media supports circular economy principles and responsible resource management.


Is lignin filter media compatible with existing filtration systems?

 

Yes. Lignin-saturated cellulose media is fully compatible with current filter designs and production processes. It can replace phenolic resin in both air and liquid filtration applications without affecting:

  • Chemical, thermal, or mechanical properties
  • Filtration performance or durability
  • Downstream processing or equipment setup

This ensures a smooth transition to a more sustainable solution.


What applications can lignin filter media be used in?

 

Lignin-based filter media is suitable for a wide range of applications, including:

Any application currently using phenolic-saturated cellulose media can seamlessly switch to our lignin-based alternative - without changes to performance, processing, or compliance.



For even greater environmental assurance, our cellulose media is available with FSC®-certified fibers - ensuring responsible forestry practices and enabling your products to carry the FSC® label.
