Glass is recycled in a plant at Auckland. The glass is then mixed with other raw materials and fed into a furnace where it is melted down to make bottles and jars.
Cardboard is sent to a mill in Auckland for processing.
Paper goes to an Auckland mill to be processed. This mill uses 100% recovered paper to make corrugated cardboard.
Tin cans and all plastics go to Auckland, where they are separated before being sent on for recycling.
Recyclable plastics 1, 2 and 5 depending on the type, are either processed here in New Zealand or sent to Australia and Southeast Asia to be made into just about anything, for example buckets, polyester fibre and wheelie bins.
Aluminium is used to make new aerosol and drink cans overseas.
Steel is made into food cans, wire and building materials in Asia.
So why does New Zealand export some recyclable materials?
Since New Zealand has a relatively small population, we don’t generate a lot of recyclable material, so there’s not as much demand for recycling processing facilities in this country.
Even though exporting our recyclables overseas means that they need to be transported further, it’s often a better environmental option than using raw materials.
