Our household recycling center's spin if it can not be used by the recycling center pour the (water-based) paint or adhesive onto a piece of cardboard and allow the water to evaporate thus "curing" (solidifying) the paint or adhesive and once dry the paint/cardboard can be disposed of as normal household (non-haz) solid.

Re; question on treatment of paint waste

As I understand the EPA rules, we can't treat regulated waste without a license to do so.  But there is a demo showing how to defloculate acrylic artists paint waste with aluminum sulfate and lime, filter, throw the water down the drain without testing, and dispose of the rest as solid waste.  Art schools and businesses are doing this.  The demo is at:

So va den?  Any wisdom on this?
