Moving to a lighter future with Renewable Functional Fillers

UPM BioMotionRenewable Functional Fillers (RFF) offer a sustainable and cost-effective solution for the rubber and plastics industry. RFF address urgent industry needs and helps to reduce the CO₂ footprint drastically.


Transforming rubber and plastics from within


We produce new-generation wood-based RFF replacing conventional fossil-based
materials for rubber and plastics production.


Renewable & CO₂ negative

UPM wood-based fillers help to reduce the CO₂ footprint of rubber products.


Weight saving up to 25% in final rubber products compared to rubber products produced with fossil-based fillers. For the automotive industry, lower weight means better mileage and lower costs.

Clean & safe

While carbon black has impurities, RFF is free of carcinogenic PAH, making it a safe solution to produce products in contact with human skin


Together for a future beyond fossils


The rubber and plastics industry uses millions of tons of fossil-based, heavy and CO₂ intensive fillers. Those non-renewable fillers, such as carbon black and silica, release large amounts of greenhouse gases into the atmosphere during production.
Global environmental regulations are becoming stricter, and industries actively seek more sustainable solutions to mitigate climate change. At UPM, we have developed a sustainable alternative to the conventional fossil-based carbon black and precipitated silica that helps cut CO₂ emissions dramatically. Therefore, the rubber and plastics industry can accelerate towards a lighter and more sustainable future.

We use responsibly sourced hardwood from regional sustainably managed forests to produce our UPM BioMotion™ Renewable Functional Fillers (RFF).


We offer solutions for


RFF are suitable for a broad range of elastomers, TPE, TPV, and plastics applications. They are perfect for automotive weatherstrip, hoses, seals, interior & exterior plastics parts, and other industrial rubber applications.

Our milestones


We plan to produce several thousand metric tons of RFF in our modern biorefinery located in Leuna, Germany. After the groundbreaking in 2020, the construction is in full swing. We expect the technical start-up for the end of 2022, with production ramped up in 2023.




  • Rubber Lab in Leuna with the most modern rubber compounding and testing equipment
  • Pilot Plant several 1,000 kg for industrial trials
  • Completed Life Cycle Analysis (LCA)

  • Industrial-scale samples from the production plant for customer approval
  • RFF customer trials

  • Commercial production
