Garbology is the study of modern refuse and trash as well as the use of trash cans, compactors and various types of trash can liners. It is a major source of information on the nature and changing patterns in modern refuse, and thereby, human society. Industries wishing to demonstrate that discards originating with their products are (or are not) important in the trash stream are avid followers of this research, as are municipalities wishing to learn whether some parts of the trash they collect has any salable value.
The studies of garbology and archaeology often overlap, because fossilized or otherwise time-modified trash preserved in middens is quite often the only remnant of ancient populations that can be found. For those who did not leave buildings, writing, tombs, trade goods, or pottery, refuse and trash are likely to be the only possible sources of information. In addition, ancient garbage sometimes contains information available in no other way, such as food remains, pollen traces of then local plants, and broken tools. As an academic discipline it was pioneered at the University of Arizona and long directed by William Rathje. The project started in 1973, originating from an idea of two students for a class project.[1]
Garbology is also used as an overtechnical term for waste management, with refuse workers called garbologists, first seen in Australia in the 1960s.[2][3]
