Is it possible to remove the pigments from the regenerated PVC compound?
It might be technically feasible to remove most of the non-organic pigments, except for carbon black. Research still needs to be conducted on removing certain organic pigments. In our current industrial projects, we have made no provision for removing pigments from the regenerated PVC compound and the relevant technology has not been developed. We will control the color of the regenerated PVC by selecting the PVC compound inflows and by adding pigments when needed.
