I need some advice.
I was just blown away by a product used in the art schools now. It is for disposing of liquid waste from acrylic paints. Be aware, that some of these paint pigments contain regulated metals such as cadmium, chrome VI, and more. There are also benzidine pigments and a lot of azo organics.
The product is designed to eliminate toxic waste from these paints. Since these are acrylics, the waste consists of water and acrylic paint. The instructions are to use a special bottle, that can deliver measured amounts of two different chemicals, and add each separately with stirring and settling time until there is clear water and schmutz at the bottom. There is filter paper and a colander so you can filter out the schmutz and throw it in your trash and then pour the clear water down the drain.
Sounds like waste treatment to me. Wadda all'y'all think?
