Aluminum cans get preferential treatment at the UW. Unlike disposal for other recyclable substances, aluminum can disposal is easily accessible through one of hundreds of aluminum bins throughout campus. "There are three types of containers used for recycling," said Mark Ghezzi, an employee of UW's recycling service and a junior in environmental studies. "There are public-area bins, toters and TAG containers. "Public-area bins are located in buildings like Kane Hall, which have larger classes and lecture halls. These aluminum-only bins can be identified by the UW logo on the front. The second type of aluminum-only bins are toter bins. These bins are located inside some buildings, but are mostly used outside. "Toter bins look like trash cans," Ghezzi said. Ghezzi added that toter bins can be found outside all over campus. Another type of recycling bin is the tin, aluminum and glass (TAG) containers. Although TAG containers have a space for glass recycling, glass really does not get recycled. "There is no market for glass refuse right now," Ghezzi said. "We just throw away all glass that is in the bins. "Ghezzi said that recycling glass is expensive because there are only a few local glass recyclers. TAG containers are the most visible because there are more than one in each building on campus. "About once a week TAG containers will be emptied into a larger container which is emptied about once or twice a month," Ghezzi said. Ghezzi said when the large recycling dumpster is full, his office calls Emerald City Recycling, which empties the dumpster and pays the UW for the contents. "How often we empty the larger container depends on the time of year," Ghezzi said. According to Ghezzi, with all of the foot traffic on campus and people in Husky Stadium, football season is the heaviest for aluminum can recycling. During this period of heavy use, the large bins are emptied more than once a month.
