Plastic milk containers make up about 15-20% of the items recycled through Dunedin City Council "blue bins". Staff writer Allison Rudd follows a container through its journey from fridge to container ship.
Milk containers and other types of plastics are shipped from Port Chalmers to mainland China via Hong Kong.
The plastic is washed, flaked and processed into tiny plastic beads which are used to manufacture other plastic products including polar fleece, a synthetic fabric used for clothing and blankets.
