Carol Clausen, a investigate microbiologist at FPL, has been dealing with microorganisms to biodegrade CCA-treated wood. Soon after grinding up CCA-treated wood, she has realized as many as ninety two% removal of copper and 42% elimination of arsenic, nevertheless the chromium is bonded extremely tightly into the Wooden lignins, and she or he has to date been unsuccessful in eliminating it.
