Bill Sheehan cofounded the Product Policy Institute (PPI) with Helen Spiegelman in 2003, and serves as its executive director. In his work at PPI, he tackles waste from every angle—from championing waste-reduction methods to promoting cleaner manufacturing processes and the use of less-toxic materials. Sheehan has been a major supporter of bringing extended producer responsibility (EPR) to the U.S., and his work has led to the formation of Product Stewardship Councils in California, New York, Texas, Vermont and other states.
