Circular Economy Explained Using the Example of Re-Frame with Hartmut Schoon & Jürgen Schmitt

Closed Loop in Practice: Turning Waste into High Performance

A plastic profile can last 280 years

What may sound surprising at first actually describes the potential of closed-loop material cycles: High-quality plastics can be reused time and again across multiple product generations .

With our closed-loop concept, we bring this potential to light. Using the example of end-of-life plastic profiles, we show how so-called waste can be transformed back into a valuable raw material. This brings the circular economy to life in practice.

From Old Profiles to Plastic Granules

After removal, the plastic profiles undergo a multi-stage processing procedure. This results in a high-purity plastic regrind, which serves as the basis for the development of high-performance compounds.

From Ground Material to High-Performance Compound

As part of our RE-Frame project, we analyze the processed material and develop a custom formulation. The result is a compound that meets the high standards of demanding applications.

Quality That Speaks for Itself

A comparison of the impact strength of a PA66 GF25 compound demonstrates just how high-performance modern re-compounds can be:

  • New: 50–60 kJ/m²
  • Conventional recompounds: 40–45 kJ/m²
  • RE-Frame PA66 GF25 from ENNEATECH: 60–70 kJ/m²


Modern re-compounds can match the performance level of virgin material and even surpass it in certain applications.

More Than Just Recycling

For us, “closed loop” means keeping valuable raw materials in circulation on a permanent basis. Together with our partners, we reduce the demand for primary raw materials andactively helpshape the circular economy.

We are convinced that the future of the plastics industry must be sustainable. Fossil resources are limited. That is why we are already focusing on innovative circular economy solutions. Those who jump on the sustainability bandwagon today are laying the groundwork for the responsible and efficient use of valuable raw materials tomorrow.

Video: Closed Loop at ENNEATECH AG

In collaboration with Deutsche Bank, we have produced a video that illustrates our closed-loop concept using a real-world example. See for yourself how innovative circular economy practices can work in real life.
