Description:
A waste minimization opportunity assessment was performed which identified areas for waste reduction at a photofinishing facility. he study followed procedures in the EPA Waste Minimization Opportunity Assessment Manual. his report identifies potential options to achieve further waste minimization progress. umber of waste producing processes were initially screened, and detailed technical evaluations were performed on wastes associated with process solutions and wash waters. ptions 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) recover of bleach fix; and (8) recovery of developer. ased on the results of the assessment phase, Options 1-4 and 7 were selected for further evaluation in the feasibility phase. he 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.
