Naturally strong: How lignin is enabling the next generation of sustainable filter media

|   Liquid Filter Media

At GESSNER, we believe that true innovation arises where performance and sustainability come together. With our cellulose fiber material with eco-friendly lignin saturation, we are addressing precisely this issue - and opening up new perspectives for eco-friendly filter media in the automotive sector.

Sustainability meets innovation

The automotive industry is at a turning point. Sustainability, circular economy, and CO₂ reduction are no longer just marketing topics, but are becoming decisive criteria in the selection of materials and suppliers.

At GESSNER, we believe that true innovation arises where performance and sustainability come together.

With our cellulose fiber material with sustainable lignin impregnation, we are addressing precisely this issue - and opening up new perspectives for eco-friendly filter media in the automotive sector.

What makes our material special?

Our innovative filter media is based on natural cellulose, a renewable raw material that naturally binds CO₂ and is reinforced by a lignin-based impregnation.

Lignin, a biogenic polymer and natural component of wood, obtained as a by-product in the paper and wood industry. It serves as a sustainable reinforcement and functional component, providing stiffness, strength and rot resistance.

This ensures that our lignin-based medium offers:

  • Meets OEM standards – a sustainable alternative delivering performance comparable to our premium-grade media
  • Easy transition - Lignin-based filter media can be easily integrated into existing filter systems
  • Optional flame retardant impregnation - For increased safety in demanding applications

The material thus strikes a balance between ecological responsibility and technical performance – a decisive step for OEMs and Tier 1 suppliers implementing sustainable vehicle concepts.

Why lignin is a game changer

Traditionally, filter media production has relied heavily on fossil-based resins. With lignin impregnation, GESSNER introduces a natural, CO₂-footprint reduced alternative that:

  • enhances mechanical strength,
  • is compatible with conventional resin systems,
  • offers broad application versatility,
  • and significantly lowers the product’s overall ecological footprint.

Combined with cellulose media, this innovation results in a more sustainable filter material with a reduced carbon footprint – perfectly suited for automotive applications that demand high technical performance..

Fields of application in the automotive industry

The lignin-impregnated cellulose medium is suitable for a wide range of applications:

  • Engine air supply & intake systems – high strength & temperature resistance
  • Oil and fuel filters – high chemical and mechanical requirements

The optional flame retardant impregnation offers additional safety, especially in applications with high temperature requirements or flammability risk – further proof of the flexibility and adaptability of the material to specific customer needs.

The lignin-based impregnation can also be transferred to all cellulose applications. This enables us to bring environmentally friendly filtration solutions to other application areas as well.

Responsibility meets innovation

With lignin impregnation, we want to show that sustainable material development and high technical requirements can be combined.

Sustainable filtration without compromise for clean, safe, and resource-efficient mobility is possible.
