About pet bottles scrap
Recyclers pay most for clear, uncoloured PET because it can be turned into fibre or new bottles without a colour penalty. Green, blue and brown bottles are recycled into darker products and are graded below clear. Sorting by colour before selling takes very little time and changes the settlement noticeably.
Caps and rings are usually polypropylene, a different polymer, and labels are often PVC or PE film. High-volume collectors are expected to remove them; for household quantities we handle it at the yard. Either way, bottles that still hold liquid are refused — the weight is water, and it contaminates the rest of the load.
Canteens, event venues, gyms and schools generate PET in bursts. For these we set up a bagged collection so bottles are compressed at source rather than transported as air.
