Amphorae were widespread and commonly used for all sorts of things, so much in fact that it seems there was a "standard" set of sizes and manufacturing processes, and there's one notable mound in Rome [0] made primarily with one type of amphora that, the theory goes on to explain, was too burdensome to recycle, so it was simply discarded in an orderly manner. This is pretty much in line with the standardization that happened with modern freight containers and allowed a substancial economic benefit, so the comparison is really on point. 0. https://en.wikipedia.org/wiki/Monte_Testaccio https://en.wikipedia.org/wiki/Monte_Testaccio
