In convention centers that recycle, OCC is one of the first materials targeted because it is plentiful, easily recognized and has an established market. Unfortunately, many convention centers have been reluctant to recover OCC because logistics of convention center operation place special constraints on handling of solid wastes.
Convention centers generate massive amounts of waste.
The work pace is often frantic, with shows opening and closing within days of each other. In order to keep the exhibition floor clear to allow the movement of people and equipment, trash must be removed as quickly as possible. It is not uncommon for custodians to work 24 continuous hours or more before the opening of a major trade show. It is reasonable to assume that a large convention center, such as McCormick Place, will generate about 2.75 pounds of waste per square foot, per year. At this rate, McCormick Place would generate 2,063 tons of waste a year.
