Circular Dairy Packaging: Closing the Virgin Cost Gap

<p>How dairy processors can close the recycled plastic cost gap with backhauled bottle returns and food-grade HDPE reuse. </p><p>Recorded live at CeMAT 2027, Shane hosts a panel discussion with Ben McCulloch from Martog &amp; Company, Edward Vaudrey from Popit Recycling, and Taylor Quinn from Procal Dairies who share how a closed-loop model could reduce the cost barrier that keeps food-grade recycled HDPE above virgin polymer. The cover:</p><p>* Why food-grade recycled HDPE usually costs more than virgin plastic, including smaller plant scale and the added collection, sorting, washing, decontamination, and extrusion steps. </p><p>* How Procal’s existing crate return network can backhaul empty milk bottles from cafés, restaurants, and other food-service sites without adding new logistics cost. </p><p>* How Popit’s modular recovery system scans bottles, removes contaminants, flakes material on site, and sends it to Martog for hot washing and food-grade processing. </p><p>* Why 30 to 50 per cent recycled content is currently the commercial sweet spot for milk bottles, even though the long-term goal is to push costs to parity with virgin resin. </p><p>* What rollout could look like next, from proving the economics at Prokal to expanding across more dairy processors in Australia. </p><p>Whether you’re a plant manager, packaging lead, or sustainability manager, this episode gives you a practical model for testing circular packaging without building an entirely new recovery network.</p><p>Follow Manufacturing Tech Australia on Spotify and leave a review if this episode helped you.</p><p>Show notes and links for this episode: https://www.manufacturingtech.au/episodes/</p>
