A Calcinator Model 10-GSX incinerator was evaluated for destruction of photographic film and silver recovery. Emissions from the stack were measured during the normal operating mode as well as during a water-spray treatment in the primary chamber to reduce the temperature. The Calcinator did not meet the 1972 Federal emission standards for particulates during the normal operation of burning photographic film, and in addition, silver recovery from the ash was low. Water-spray treatment, however, does reduce the emissions, but it complicates control of the burning process so that a minimization of ash weight is difficult to achieve. Author
