Aliaxis’ joint venture opens the first large-scale plastic recovery facility in New Zealand

Plastics Recycling NZ (PRNZ), a joint venture between Waste Management New Zealand and Aliaxis New Zealand, opened a new advanced plastic recovery facility in Auckland, on New Zealand’s North Island in March 2025. This development follows PRNZ’s acquisition of a Christchurch-based plastic recycling facility in 2023, which secured the joint venture’s capabilities in recycled material in the South Island. The facility processes both PVC and HDPE plastics and represents a total investment of over $8.5 million. The facility is the first large-scale PVC recovery plant in New Zealand marking a significant milestone in the country’s journey toward a circular economy.

Climate change mitigation, primarily achieved through decarbonization, and the circular economy remain priorities for Aliaxis. We are contributing to global decarbonization and the circular economy by developing products with recycled content, reducing our environmental impact with efficiency programs, fostering sustainable practices, and increasing the amount of renewable electricity across our operations.

“Aliaxis is committed to sustainable plastic use and long-term carbon reduction. This initiative aims to deliver a carbon footprint reduction of more than 5000 tons, contributing towards our New Zealand and global Science Based Targets initiative* scope 3 carbon reduction targets,” says Elliott Burke, Managing Director, Aliaxis New Zealand.

The new plastics recovery facility offers a seamless circular solution for processing PVC and HDPE waste to meet the needs of the construction industry. Equipped with state-of-the-art washing technology to remove dirt and debris, the facility plans to transform thousands of tons of plastic waste annually into valuable recycled materials.

Under the partnership, WM New Zealand operates the facility and manages a network of collection services for PVC and HDPE materials. Processed materials are then supplied to Aliaxis for manufacture into new piping systems, delivering a true circular economy solution.

*Aliaxis has committed to setting near-term company-wide emission reductions in line with climate science with the Science Based Targets initiative (SBTi).
