Well-planned landfills have only recently come into widespread use. Recently, waste managers have found that they work a little too well and now the landfill is being reinvented.
In this Stuff You Should Know episode, Josh and Chuck dive into the surprisingly complex world of landfills, exploring how modern waste management works from the inside out. They trace the evolution from the terrible "dump it in the ocean" days to today's sophisticated sanitary landfills, breaking down everything from bottom liners and leachate collection systems to methane harvesting and the newer "bioreactor" landfills that speed up decomposition. The hosts also tackle some fascinating tidbits, like sports stadiums built on old landfills and the emerging economics of interstate garbage trucking that's turning some states into trash magnets.
