A number of recycles don't want anything to do with the stuff and only take it at a deeply discounted rate.

I tried that but these local people on the monthly recycle pickup seem to equate pop & beer cans with alu and didn't take a bag of alu swarf. > I used to run them through an antique meat > grinder, but that was too much work.

I don't know if once proves the point. It did make quite a flash though. I had a thumb poised over the esc key just in case, but when it came time to move it again, it moved as per told.
