The rise of curbside recycling programs over the past few decades has meant more glass recycling. But for a long time, many recycling centers didn’t have the technology to turn recycled glass into the raw material for new bottles. Instead, recycled glass often wound up being used as a cheap construction material, or even to cover landfills.
Now, with new technology that can better sort glass collected in curbside recycling, more used glass bottles can be turned back into new glass bottles. To see how this works, we went to a glass recycling facility and a bottle factory.
