How dairy processors can close the recycled plastic cost gap with backhauled bottle returns and food-grade HDPE reuse. Recorded live at CeMAT 2027, Shane hosts a panel discussion with Ben McCulloch from Martog & 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: * 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. * 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. * 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. * 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. * What rollout could look like next, from proving the economics at Prokal to expanding across more dairy processors in Australia. 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.
