Jeff Borrman, CEO, Bioscope Technologies, explains the Bioleaching and Bio-refining processes it is developing at industrial scale for the sustainable recovery of base and precious metals from printed circuit boards (PCBs). Bioscope technology will replace traditional treatments that use high-temperature and chemical recovery and is as close to zero-emission as possible, without offsetting. The company is making a multimillion-pound investment in plant and machinery across its four UK PCB recovery and processing facilities as it anticipates a huge growth in industrial scale, sustainable recovery of precious metals.
