A Waste Management Inc. subsidiary and Pfizer Inc. are jointly offering a free online pharmaceutical disposal guide for health care operations. 

WM Healthcare Solutions Inc., a subsidiary of Houston-based Waste Management, along with the New York-based pharmaceutical company have introduced the Pfizer Responsible Disposal Advisor to help guide health care professionals through sometimes-complex waste disposal requirements, the companies said in a news release.

WM Healthcare is providing its PharmE Waste Wizard technology to the venture. Waste Wizard is a search engine that provides waste categorization and disposal information for all health care facilities, including physician practices, clinics, ambulatory surgery centers and walk-in clinics.

Waste Wizard informs health care officials whether the Pfizer drug to be disposed of will be considered a hazardous waste.
