All of our operations have developed novel technologies to treat new manufacturing waste streams which has enabled us to become market leaders.

However technology is not just limited to our refining processes as IT is another fundamental driver of our business.  Investment has been made at all our operations to install a dedicated refining administration programme that can allow us to respond quickly to customer enquiries.

Our laboratories at Tennessee and Hatton Garden have recently had a complete refit to install new spectrographic analysis equipment together with increased capacity to allow us to provide a faster assay service to our customers.
