NZ plastics industry targets hard-to-recycle waste streams

Plastics New Zealand in collaboration with industry has released two reports outlining strategies for addressing the nation’s construction and packaging plastic waste crisis.

Over 5000 tonnes of Expanded Polystyrene (EPS) packaging enters New Zealand’s supply chains every year, yet nearly 77% currently ends up in landfills or as environmental pollution due to limited collection and recycling systems. Meanwhile, Auckland alone sends approximately 25,000 tonnes of construction and demolition (C&D) plastics to landfill annually.

Two reports have been developed outlining strategies aimed at improving how these problematic plastics are managed across the country.

“Plastics are essential to modern life — offering durability, efficiency and performance in applications ranging from construction materials to medical packaging. These reports focus on ensuring those benefits are realised without compromising our environment,” said Rachel Barker, CEO of Plastics New Zealand.

“Our landfills are rapidly filling with plastic waste from construction and EPS packaging — these reports offer tangible solutions that can significantly change the status quo.”

The ‘Construction & Demolition Plastics Report’ highlights strategies for managing the three largest plastic waste streams from construction sites: soft plastics, PVC/HDPE and EPS. It emphasises the need for improved onsite practices, targeted recycling infrastructure and clear accountability measures to reduce waste.

The EPS Product Stewardship report identifies pathways for recovering EPS packaging used in consumer goods, medical and seafood sectors. It advocates for a robust, industry-led national stewardship scheme, highlighting opportunities for both regional and trans-Tasman recycling solutions.

“These reports aren’t theoretical — they’re practical roadmaps developed with input from across the industry, including manufacturers, recyclers, local government and environmental experts,” Barker explained. “Now we need stakeholders from every sector to step forward and join us in turning these strategies into action.”
