 | | WHEN I FIRST HEARD of it, I could hardly believe it—that after the garbage is collected twice a week in the city of Tucson, some of those big plastic bags are opened and the contents painstakingly examined, classified, weighed, and recorded by students from the University of Arizona. |
 | | The garbage we examine is grouped by individual households, but, for the sake of individual privacy, these are never identified by name or ad-dress; instead, the recording is done by census tracts, care-fully chosen because they are inhabited by identifiable socioeconomic groups. |
 | | DICTIONARIES define garbage as food waste, refuse, trash, material that's useless or unwanted; the mayors and county officials responsible for dealing with what their constituents throw away call it municipal solid waste. |
