Good subject, trash in the US: and a good hook, the Garbage Project, Rathje's combination of (zero-day) archaeology and (zero-distance) anthropology. I think it got too popped up, though, too reduced to bite-sized anecdotes, and is aging poorly. (Rathje's writing online has more pith.)
Both Fat of the Land and Waste and Want are better books on the history of waste in the U.S. Both have stronger narrative and are willing to go into more systematic detail about less "pop" topics.
I'd like more of the anthropology.
