we have developed a spent bath regeneration process

green etCHing® uses only substances with a low environmental impact and non-toxic-harmful:

NaOH
Complexing additives

The emissions consist of hydrogen and alkaline vapors: they do not require special abatement systems The residues to be disposed of (exhausted bath and sludge) are not toxic-harmful (special waste with low environmental impact); moreover, with the developed regeneration process it is possible to regenerate the exhausted bath and obtain a recoverable residue.

For the regeneration of the exhausted bath, green etCHing® has obtained the international PCT patent
