Clean Harbors Environmental Services announces an update to its online pharmaceutical waste management estimator for hospital pharmacies. The estimator is now designed to incorporate and support group purchasing organization information. Available on the Clean Harbors Web site, the tool provides a menu of service/ cost options and top-line estimates of costs. The online questionnaire collects basic organization, bed census, and services information, and then develops six waste management service options that include levels, frequency, and three-year estimates. Responses are sent via email, fax, or postal mail.
