The crushing machinery absolutely hates plastic bags as these don’t crush with the gravels; they just stretch and become a contaminant in the basecourse material. It is really important to keep plastic bags, bottles and sleeves out of the skips as if we have too much contamination it could put the whole glass recycling project at risk. (By sleeves we mean the plastic labels around some RTD bottles – best to throw those bottles in your rubbish bag for landfill disposal or, better still, avoid purchasing that type of packaging in the first place!)
Metal screw caps and paper labels left on bottles is fine. Corks, however, are also a problem and should be disposed of to landfill.
