The companies which are more proactive towards the introduction
of BATs are those providing chrome treatments, electrolytic
polishing and nickel plating. On the other hand,
phosphating and tin-plating are the processes currently showing
the largest technological gaps. With regard to chrome-plating, efforts are mainly concentrated on reducing water for washing
and drag-out as well. As expected, recycling processes are
widespread in the working of precious metals, given the high
residual value of the recuperated materials. It remains less interest
in introducing BAT in the pre-treatment phases.
