Apology for cross posting and please forward to appropriate regional P2 listserves.
The Small Business Pollution Prevention Center has recently posted the Impact of Pollution Prevention tools at http://www.iwrc.org/SBPPC/index.htm
I hope that the data presented in this project is useful to your clients and in assisting with more meaningful measurements as to the actual impact of P2 by quantifying the toxins reduced when P2 suggestions are implemented.
