RE:RE:QRR news releaseIf one is looking to be able to make a comparrison of their production process against the process a competitor uses I think you would want to use the same quality of product. Then a true comparrison can be made on the costs for the finished product. Plus the comparrison of which product was produced with a greener production process would also be equal.
Once they have proven the HPQ process is cheaper and greener using all the same input products of their competitor they can then bring in lower quality quartz to prove their processes.
