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.

AI サマリー（NQ 加工済み）

Riken Technos is collaborating with Tohoku University on a new recycling technology for PVC wire harness coatings. The technology, an advanced wet separation process, uses solvents and a ball mill to achieve higher purity separation of PVC from copper compared to the conventional nugget method. Lab tests have successfully produced a compound with 40% recycled content that matches the physical properties of new materials.
