Some spent nickel catalysts contain cancer-causing nickel oxide and others may contain nickel sulphide or other “nasties” that must be handled correctly.
As well as affecting the purity of the recycled metal, if the dangerous substances are not handled safely it could create a problem for recycling and pose a threat to the workers at the recycling plant or the wider environment, so if there are any contaminants in the waste, we must be informed prior to its shipment so that these contaminants can be dealt with in the safest way possible.
