edical waste management is perhaps the least desirable item that has to be dealt with by hospitals. It is also one of the most important functions a hospital has to address. As modern hospitals have increased in size and patient capacity, the labor- intensive collection and disposal of waste have become more difficult and thus more expensive. To meet this problem, various methods of waste collection have been tried to varying degrees of success. Of course, the methods of collection differ from facility to facility with most still relying on manual labor. In an increasing number of hospitals, especially large facilities, the use of Automated Guided Vehicle Systems (AGVS) is becoming more and more popular. First introduced back in the late 1960’s as a labor-saving way of material handling in places as diverse as printing plants and automotive manufacturing, these robotic systems began to be adopted by hospitals as a way to distribute supplies and collect both medical waste and general trash. According to Ed Schachinger, president of The Schachinger Group, a Fairfax, VA-based consulting firm specializing in materials handling and management, including waste management, there are now approximately 30 hospitals in the US of some 300 to 350 hospitals worldwide that use AGV systems.
Typically, The Schachinger Group provides its hospital clients physical and economic feasibility studies followed by functional and space programming. It then designs and writes specifications for highly sophisticated materials and waste management systems including AGVS. “We create the specifications and then a set of drawings. Vendors then bid on the system and we consult with the hospital as to which system is best suited for its needs,” Schachinger noted. He said a 700-800-bed hospital needs between 35-45 AGVs while a 1,000-bed hospital needs over 50 vehicles. AGVs are integrated robotic systems employing self-powered wheeled vehicles that pick up and deliver waste and materials on a pre-programmed, guided route, according to Bob Baker, Manager of Technical Services at The Schachinger Group. The vehicles can follow a path of buried magnets, an eye-safe laser system that follows wall-mounted targets using triangulation to fix the position of the vehicle enabling it to follow a defined path, or a contour following system that knows the hospital layout and identifies landmarks to navigate. The vehicles generally stay within one-half to one-quarter inch of their planned route. Also the robot is in constant wireless communication with a central command station. According to Baker, in most hospitals medical Continued on page 3
