MANN-FILTER Sustainability: MANN+HUMMEL Integrates Lignin to Cut CO2 Emissions

MANN-FILTER Sustainability has taken a measurable step forward as MANN+HUMMEL GmbH (MANN+HUMMEL) integrates the renewable raw material lignin into the coating of its cellulose filter media. The move reinforces the company’s commitment to lowering the environmental footprint of its filtration portfolio while ensuring consistent product performance. This initiative is part of the “Naturally Better” campaign, which was recognized with the German Design Award 2026, underlining both its technical and sustainability impact.

MANN-FILTER Sustainability Through Renewable Lignin Integration

MANN+HUMMEL has replaced a portion of fossil-based inputs in its cellulose media coating with lignin, a renewable raw material derived primarily from wood processing. This transition directly supports sustainable filtration technology by reducing dependence on crude oil–based substances traditionally used in filter manufacturing. The integration aligns with broader industry goals focused on green automotive manufacturing and improved resource efficiency across supply chains.

Lower CO2 Emissions and Reduced Crude Oil Use

By incorporating lignin into the cellulose coating, the company reports:

• Up to 5% reduction in CO2 emissions during production

• 27% decrease in crude oil consumption in the coating process

• No compromise on product quality or filtration performance

These measurable improvements contribute to CO2 emission reduction in automotive component manufacturing while maintaining strict durability and efficiency standards expected from MANN-FILTER products.

Maintaining Performance Standards in Sustainable Filtration Technology

A critical aspect of MANN-FILTER Sustainability is ensuring that environmental gains do not come at the expense of filtration efficiency or reliability. According to the company, the lignin cellulose coating delivers equivalent performance characteristics compared to conventional fossil-based solutions. This balance between sustainability and technical integrity positions the product line as a practical solution for customers seeking eco friendly filter production without operational trade-offs. The award-winning “Naturally Better” campaign further highlights how renewable raw materials can be integrated into mainstream automotive components at scale. With reduced crude oil dependency and verified emission savings, MANN+HUMMEL strengthens its role in advancing sustainable filtration technology while meeting evolving environmental expectations across global automotive markets.
