Recycling Friction Goal of Cooperating German Firms

LEVERKUSEN, Germany – A joint project by two Leverkusen-based companies enables a recycling process for friction materials with drastic CO2 savings compared to conventional production and disposal.

Sustainable friction material recycling allows the reuse of valuable raw materials

So far, brake pads and linings have been produced with raw materials sourced all over the world, with phenolic resin as a binder, under pressure and heat in multiple heating- and cooling cycles with high energy consumptions. After only about 50 percent wear, these pads are usually replaced with original pads (OES) or pads from the aftermarket.

Today, most used pads are landfilled and therefore not recycled.

This is where the two companies with their LIQFRIC® and Green Friction® processes come in:

LF GmbH & Co. KG produces the castable raw material LIQFRIC® with selected – uncritical – raw materials with the addition of an inorganic binder on a liquid basis. This material is then further processed into original equipment or aftermarket pads without pressure and very little heat exposure.

This process saves up to 85 percent CO2 compared to conventional manufacturing. Another advantage is the drastically reduced PM10 fine particle emission. The low-temperature process also allows sensors to be integrated directly into the pads.

LIQFRIC® and Green Friction® offer a joint, mono-material and sustainable recycling process for brake pads

For more than 25 years, RMS has been sustainably recycling friction materials and grinding dust from production scrap and used pads from car, truck, motorcycle, rail, and industrial applications.

After separating all metallic parts, the friction material is processed according to the Green Friction® recycling process, optimized to customer specifications, and re-used as a valuable component in new friction material mixes.

An independent life cycle assessment study, performed according to ISO 14040 / 14044, shows that this recycling material has an up to 92 percent reduced product carbon footprint compared to conventional friction materials made from 100 percent virgin raw materials.

The joint cooperation guarantees the homogeneous recycling of the LIQFRIC® production rejects. Thanks to the Green Friction® recycling process, the innovative LIQFRIC® ecological balance can be made even more sustainable.

Conclusion

Reduced energy consumption – 85 percent CO2 reduction during production – significantly less particle emissions PM10 – IoT-capable – high-performance – approaching serial production – controlled return through a closed, sustainable recycling concept – applied sustainability.
