Plastic recycling. View of discarded plastic drinks bottles being loaded into a compactor at a recycling facility. Most plastic bottles used for soft drinks are now made of PET (polyethylene- teraphthalate), a plastic which is recyclable. At the start of the process, the bottles are compacted into bales, then shredded. The plastic chips thus formed are cleaned, then sent to be used in new bottles. Photographed at New Westminster, Canada.
