SPOKANE, Wash. – Each day U.S. hospitals create about 6,600 tons of waste. That doesn’t count the unwanted by-products made by doctors’ offices and other health care facilities.

Where does it all go? How much of it is preventable? What are health care providers doing to reduce their environmental legacy?

Those are questions Missoula, Mont., registered nurse Beth Schenk has studied informally for many years. Now the Washington State University College of Nursing doctoral student is turning what she has learned into a dissertation.

Schenk will speak about “Creating a Sustainable Health Care System: An Action Agenda for Clinicians” from 12-1 p.m. Friday, Feb. 11, in Academic Center 147 on the WSU Spokane campus. The lecture is free and open to the public.
