When in Ancient Rome, recycle: Evidence of garbage reuse found in Pompeii

Almost two thousand years ago, long before the invention of the blue bin, people in the ancient city of Pompeii were recycling.

Researchers recently discovered that what was initially thought to be a landfill site, outside the walls of the famously well-preserved city, was actually a recycling centre of sorts. Discarded materials stored there were reused in the construction of buildings.

“It’s always going to take less effort, less investment if we reuse things rather than just discarding them and starting over with new material. So in the ancient world, this just makes sense,” Allison Emmerson, a researcher studying Pompeii, told As It Happens host Carol Off.

Emmerson is a professor of classical studies at Tulane University in New Orleans. She says analysis of Pompeii’s ruins connects the piles of waste just outside the city walls to materials found within it. 

“Looking at the Pompeiians, they seemed to have a very different attitude towards garbage than we do. They’re much more tolerant of it in urban spaces,” she said. 

Pompeii, near Naples, was buried by volcanic ash when Mount Vesuvius erupted in AD 79, killing at least 2,000 people. Much of the city was preserved in the ash. Excavation began in the mid-1700s and the city has been studied ever since.

Soil samples show how waste moved

By using soil samples to trace the movement of material to and from Pompeii’s waste piles, Emmerson and colleagues from the University of Cincinnati concluded many walls and floors within the city’s commercial district were built using re-used material such stones and pieces of tile, pottery and plaster.

“We started to be able to reconstruct the system of use and re-use in which waste is leaving the city, piling up outside of it, becoming valuable by gathering en masse and then being carried back in to be used as building material,” Emmerson said.  

She said the Pompeii findings showcase a different method of managing waste than most modern cities practice.  

“We put no value into so much of what we bring into our homes. We’re just happy to get rid of it the next day. But for most of human history, we just didn’t have that ability, both because [waste] couldn’t easily be taken away and because getting it in the first place was much more difficult,” Emmerson said.

“From a modern perspective, our ability to remove garbage so easily and to stop thinking about it — or we think so easily — has led us to a fairly unnatural viewpoint, which is that garbage should just be carted away and we should never have to think about it again. Obviously, that’s not working out so well for the world right now.”
