Plastics For the Environment : A Celebration of Positive Plastics
Plastics For the Environment? A Celebration of Positive Plastics.
As Conservation Week approaches, it’s a great time to reflect on how the plastics sector is uniquely positioned to support New Zealand’s biodiversity.
While plastic is often central to conversations about environmental challenges, our industry is increasingly providing the very tools needed to protect and restore our previous ecosystems.
From wetland preservation to large-scale reforestation, innovative plastic products are proving to be essential allies for the Department of Conservation (DOC) and community groups across Aotearoa.
We have previously highlighted innovations in biodegradable horticulture products created by some of PNZ’s members such as Scion, EPL, and Extrutec through their Earthwine brand. Biodegradable items such as horticultural twine, vine clips, and plant pots are able to support with growing and return nutritional value to the earth when discarded. Complementing these 'circular by design' solutions are high-performance recycled plastics engineered to withstand harsh conditions over time.
Garto produces weed-suppression tree protectors made from 100% recycled NZ plastics. Their UV-stabilised guards create a warm micro-climate that accelerates plant growth and suppresses competing weeds. This significantly reduces the need for herbicide spraying in restoration areas, offering a "set and forget" solution that stays functional for up to a decade before they should be recovered and recycled again.
Similarly, companies like Kiwireco are providing the "scaffolding" for reforestation through recycled plastic tree stakes, ties, and trunk protectors. These products are vital for protecting young natives from wind, pests, and livestock during their most vulnerable years. By turning recycled material into high-utility conservation tools, the industry is closing the loop while helping New Zealand grow greener. It’s a powerful reminder that high-performance plastic is often the most resource-efficient choice for long-term environmental protection.
This Conservation Week, we encourage all industry players to celebrate our industry’s role in protecting our environment and reassess how your own products or materials might support local restoration efforts.
Whether it’s through supporting a community planting day or developing the next generation of circular conservation tools, the plastics sector has a vital role to play in ensuring our natural heritage thrives for generations to come.
