A waste minimization opportunity assessment was performed which identified areas for waste reduction at a photofinishing facility. The study followed procedures in the EPA Waste Minimization Opportunity Assessment Manual. The report identifies potential options to achieve further waste minimization progress. A number of waste producing processes were initially screened, and detailed technical evaluations were performed on wastes associated with process solutions and wash waters. Options identified were as follows: (1) wash water control; (2) silver recovery--metal replacement cartridges; (3) silver recovery--electrowinning (4) electrowinning with MRC tailing; (5) recovery of silver--ion exchange; (6) recovery of fixer; (7) recovery of bleach fix; and (8) recovery of developer. Based on the results of the assessment phase, Options 1-4 and 7 were selected for further evaluation in the feasibility phase. The results of the study indicate the fastest payback would be realized from Options 1 and 7 assuming Accuphoto's willingness to recycle bleach and no production increases.
