Incineration of Residue from Paint Stripping Operations Using Plastic Media Blasting

Show full item recordAbstract
A preliminary investigation has been performed
on the environmental consequences of incinerating
plastic-media-blasting (PHB) wastes from paint
removal operations. PHB is similar to sandblasting
although blasting takes place at a much lower pressure.
The blasted media can be recovered and recycled
several times, but ultimately a residue of
paint dust/chips and attrited media dust are left
for disposal. This residue is a dry solid that may
potentially be classified as a hazardous waste. One
possible alternative to depositing the waste residue
directly into a hazardous waste landfill is incineration.
Incineration would provide desirable volume
reduction. However, the fate of heavy metals from
the entrained paint waste is not known.
Samples of PHB residue were combusted at temperatures
between 690°C and 815°C with approximately
125% of stoichiometric air. The ash remaining after
combustion was then analyzed for heavy metal content
and tested for leachability using the EPA toxicity
characteristics leaching procedures (TCLP).
