Hemp packaging could be a game-changer for reducing plastic pollution, and a mix of international innovation and local opportunities could see this happen. In Germany, exciting developments in hemp packaging have already shown the potential of this sustainable solution, with lessons New Zealand and Australia could build upon by repurposing existing pulp mills.
In Germany, Cartomat is producing of hemp paper using locally sourced hemp from within a 20 km radius of its factory operations. This approach not only reduces transportation emissions but also supports regional agriculture. The resulting packaging, known as carto hemp paper, boasts exceptional strength, tear resistance, and moisture-proof qualities, making it a viable alternative to plastic. As well it’s been proven to keep food fresher for longer - tomatoes stored in this hemp paper stayed fresh for up to three weeks, far outperforming traditional polyethylene bags.

This innovative model could inspire New Zealand and Australia to adapt their timber-based pulp mills to process hemp. Many of these mills, like Pan Pac's Hawke’s Bay facility and the Kinleith Pulp & Paper Mill in New Zealand, have faced challenges in recent years due to rising costs and market shifts. Similarly, Australia's Maryvale Mill in Victoria, with its extensive infrastructure, could move toward processing hemp fibre. Such transitions would not only revitalise these industries but also create a circular economy where locally grown hemp supplies sustainable packaging solutions.

The environmental benefits of hemp are compelling. Hemp grows rapidly, requires little water, and needs no pesticides. It’s also biodegradable, breaking down naturally without contributing to the plastic waste crisis. Additionally, hemp cultivation absorbs significant amounts of carbon dioxide, offering a natural way to increase planetary oxygen levels. Repurposing existing pulp mills to process hemp could provide the dual benefit of reducing reliance on plastic while creating packaging that’s strong, eco-friendly, and sustainable.
By blending German innovation with local adaptation, New Zealand and Australia have a unique opportunity to lead in sustainable packaging. This approach not only tackles plastic pollution but also boosts regional economies, supports local farmers, and addresses global environmental challenges. The future of packaging might just be growing in our backyards.
