Who is involved in this joint research?

Riken Technos Corporation is collaborating with a research group led by Professor Yoshioka and Associate Professor Kumagai from Tohoku University's Graduate School of Environmental Studies.

What specific material is being recycled?

They are recycling the Polyvinyl Chloride (PVC) coating material from automotive wire harnesses recovered from end-of-life vehicles.

How does the new recycling technology work?

It is an advanced wet separation process where the wire harness is soaked in an organic solvent to swell the PVC coating, then a ball mill applies impact to separate the PVC from the copper wire.

What is the main advantage of this new method over the traditional 'nugget method'?

The new method has a much higher separation performance, allowing for the recovery of high-purity PVC material, which is difficult with the nugget method where the material is often contaminated.

What success has been achieved in the lab so far?

They have successfully created a re-compounded material containing up to 40% recycled PVC coating that exhibits mechanical properties equivalent to those of conventional, new products.
