Recycled powder cores that contribute to carbon neutrality.

Recycled powder cores that contribute to carbon neutrality.

Not only will we reduce CO₂, but we will also contribute to the realization of a circular economy.

A recycling example of powdering used powder cores and reforming them into powder cores again. - Since powder cores are easy to crush, the cores are crushed, processed, and reused. - This contributes not only to CO₂ reduction but also to the realization of a circular economy.
