"With the decline in the productive capacity of the South African economy, the country needs sufficiently differentiated innovations, such as the Rotowinner®, which have enormous potential to compete on a global scale. We are also particularly pleased at the responsiveness from big business — particularly Impala Refineries — to the call to collaborate in demonstrating the commercial potential at scale."

"We are particulary pleased to have the opportunity to collaborate with South African technology developers, Free Radical Process Design, who have worked with the University of Pretoria to develop an innovative technology that could have a global impact in the treatment of contaminated mine water, and which is directly applicable to our Prieska Mine dewatering challenge. In addition to agricultural nutrients, other products can potentially be extracted using the Rotowinner Technology which are used in the chemical industry, opening up interesting future by-product sales opportunities."

"After some initial teething problems, FRPD's Rotowinner demonstration plant was able to continuously produce thin strips or flaked metallic product from the plant feeds provided. Internal analysis of the products indicated it to be of similar quality to the metals currently produced in our commercial plant. The technology has the potential to produce final product on a continuous basis, on a small footprint, and with limited interaction required by operators. The basis of the technology - electrowinning of metals - gives it scope to produce various metals. We focussed on copper production specifically, as well as the purification of process streams by removing the unwanted residual metals present."
