Summary

The tightening of EPA waste disposal regulations is increasingly making it practical to minimize porcelain enamel waste generation. Almost all porcelain plants are wasting 25% of their purchased enamel materials. At least 75% of this wasted material is recoverable by using common sense and improving housekeeping. Employees can be trained to minimize waste; the design can be improved for mill rooms, spray booths, flow coaters, and dip lines, One plant enameling 2500 units a day was wasting 100 000 Ib of enamel monthly, which totaled $900 000 a year. The plant was able to make dramatic reductions in waste generation just by using common sense. Regarding EPA matters, it is expected that in 1989 the extraction procedure (EP) test will be replaced by the EPA with the toxicity characteristic leaching procedure (TCLP). The TCLP test is more aggressive and will mean that more enamel waste will be labeled as hazardous. The allowable level of lead in waste will likely be reduced substantially.
