The plastics to be phased out include hard-to-recycle food and drink packaging made from PVC and polystyrene, and some degradable plastic products. 

They can recycle a lot of PVC, PET, ABS and a variety of other plastics.

PVC, like all other thermoplastics, is fully recyclable.  At the end of their life, PVC pipes can be collected, recycled and turned into other products.  The catch is that there has to be the processing technology available, and there needs to be a market for the recycled material.  This is where the pipe manufacturing industry in New Zealand has stepped up to ‘close the loop’ by providing the solution to the recycling of their products.

Clean PVC pipe can be delivered to recycling facilities in Auckland, Palmerston North, Christchurch and Ashburton. Loads are inspected to ensure there is no contamination.  The recycling process requires there to be no other materials, dirt, or stones as these will cause problems for the recycling machinery. 

This means a load must not contain;

• other materials such as wood or paper,
• any other types of plastic products,
• excessively dirty pipe,
• or pipe used for sewage.
• The success of this recycling scheme is highly dependent on ensuring the pipe for recycling is free of contaminants.  It is important that customers sort their waste thoroughly before delivering.

Both PE and PVC pipe material is accepted for recycling.  The two different types of pipe are separated at the recycling centres for processing.  After sorting, the pipe is ground up and recycled into other pipe applications like drain flow coil pipe.  In some cases recycled material is incorporated into new pipe by sandwiching recycled material between thin layers of virgin plastic.
