not sure if this would work, but definately very topical. How about some research / report into reducing any environmental impact of salons / spas.

I am quite worried about the general waste from my salon - rolls and rolls of couch roll (that has generally just been laid upon by someone often fully clothed), fabric or paper wax strips, soiled cotton wool etc ........ Old tubes from sunbeds. All of these things are of course disposed of in the proper manner, but I sometimes wonder if there are alternatives.

In a spa you would have other factors as well, ie the chemical adjusters required for pools/jacuzzis, chlorine etc. The energy implications of such facilities with the heaters, pumps and filters running. The number of towels laundered daily etc.......

I am not an "environmentalist" and dont have answers to the above - just a suggestion for your research. But please whatever happens, dont produce anything that will result in further regulations for us!
