Perc is used extensively in the preparation of printing plates,
particularly Cyrel plates (which are still made and sold by Dupont). Most
perc is either recycled on site using a distiller or sent to a central
distillation facility for recycling.
Dupont offer a much safer alternative called "Optisol" and there are a
couple of other manufacturers making safer alternates. Unfortunately perc
is much cheaper and works much faster so it still dominates the market.
Optisol can also be recycled on and off site.
