Disposal Method
X-Ray fixer waste contains high silver content and will most likely constitute hazardous waste , however fixer is readily recyclable . Recycling is the waste management method recommended by both PDA and regulatory agencies .
There are two suitable methods of recycling fixer waste : 1 ) using a silver recovery unit for your developing system 2 ) using a licensed silver recycler .
If you use your own recovery unit , liquid that is run through the unit usually can be disposed of down the drain into the public sewer system . This should be confirmed with your local sewage treatment plant or municipality .
If you choose to use a licensed silver recycler , the used fixer should be collected and stored in a closed plastic container labeled “ Used Fixer .”
Mixed developer and fixer solutions will either need to be recycled by a licensed silver recycler or disposed of as hazardous waste . If recycling , the mixture should be collected and stored in a closed plastic container labeled “ Used Fixer and Developer .”
You may also purchase an adapter kit for your silver recovery unit to keep the solutions separate .
