Seeing a glass recovery line in action makes it obvious why sorting accuracy matters – what looks like a single stream of crushed glass is actually a mix that needs careful separation before it's worth anything.
A new after-composting glass recovery line has gone into operation at the Waste Recovery Center of Maresme, recovering glass from municipal solid waste (MSU) that has already passed through composting.
Glass recovered at this stage of the process tends to be more contaminated and harder to separate than glass collected separately from the start – mixed with organic residue, ceramics and other materials left over from the composting process. A recovery line at this point in the cycle is, in effect, a second chance to capture glass that would otherwise be lost to the residual waste stream entirely.
This kind of installation shows how recovery doesn't stop at the first sorting stage – even after composting, there's still recoverable value in what remains, provided the sorting technology is capable of handling material that's more degraded and mixed than a typical glass collection stream.
