Photographic Waste Utilization.
Abstract
The objective of this program was to incorporate photographic processing wastes into a useful product, or to render the wastes harmless for a Class 3 landfill. The wastes were incorporated into a cold-setting ceramic foam, a ceramic castable, and an ultramarine pigment. Technical and economic evaluations indicated the foams might possibly be used for insulating firebricks up to 2000 F, and sold at a profit, the castables could be used as an insulating castable up to 2000 F, but probably not sold at a profit; and the pigments could be made, but not profitably. From environmental exposure tests, for safe photowaste disposal in a Class 3 landfill, the 1000 F cured, clay-containing foam (preferred) or the room temperature cured, nonclay-containing foam, appear suitable as long as the landfill is not excessively alkaline. For excessively alkaline landfills, a 1000 F cured clay-containing castable appears suitable. The recommended level of photowaste incorporation is 10-20% by weight of green ceramic. (Author)
