I noticed recently that the person collecting the bottles from our local bottle bank seemed to empty the bottles from the green glass container, the brown glass and clear glass container in to the back of one lorry all on top of each other. Is this the case? If so why do we bother separating our coloured glass in to different containers.
I was told by someone who works in waste management that all recycled glass gets passed through a machine that uses lasers and sensors to identify the colours and separate it accordingly
