ChroRePro: Chromium Recovery Process
Separation and recovery of chromium from plating industry wastewaters
01.
Identification
Circular Materials was funded in April 2019 to solve the challenges related to the removal and recovery of heavy metals from industrial wastewaters. Currently, only 5% of the heavy metals from spent baths in the galvanic and plating industry are recycled: the rest is converted to toxic sludges and sent to landfill as special waste, steeply increasing the treatment cost. They have patented a technology where we recover in the form of powders the 99% of heavy metals present in industrial wastewaters, by means of a sustainable and environmentally friendly precipitation process in supercritical water. The process does not produce any toxic sludge, it recovers valuable metals to be reintroduced in the industrial process or sold as secondary raw materials.
