Our Background

Curtis Bay Medical Waste Services was conceived, designed and built in cooperation with members of the Maryland Hospital Association in 1991 to provide a regional solution to the medical waste management requirements with the goal of building a facility to provide local specialty waste services and eliminating the need for each facility to provide their own incineration services.
