Chemgon
Chemgon™ is an EPA approved, easy to use method of disposing BOTH spent fixer and developer.
Simply pour equal amounts of developer and fixer into the Chemgon 5 container. The liquid mixes with Chemgon's special patented dry ingredient causing the sponge-like material to solidify and bind the silver. When full, simply throw the Chemgon container away with your normal trash.
EPA approved in all 50 states. Note: California is the only state we are aware of that requires small quantity generators to obtain a hazardous waste treatment permit to treat silver-laden photo-processing waste.
Capacity: 5 gallons. That's 10 drains of 2 quarts each when using either an ImageMax or PeriPro film processor.
