Zirconium oxide and yttrium oxide recycling

Hello,
We are jewelry manufacturer in Thailand, named Pandora Production Thailand.
Since we are focusing on Sustainability, we have a project to make our supply chain of Cubic Zirconia become more sustainable.
Since you have the method for recycling zirconium oxide and yttrium oxide, we would like to learn more on this and to check we can collaborate in business to have better materials (green material-Cubic Zirconia).
