Claire Kneller: Trash Talk — Complex Landscape of Household Food Waste | On the House #61

·1 hr 20 min·5 clips

In Australia, about 70% of household food thrown away could have been eaten.

1. On the House #61 focuses on Claire Kneller and the complex landscape of household food waste in Australia. 2. Gabriella Jastra hosts the episode, and Claire Kneller appears as Managing Director of WRAP Asia Pacific, with WRAP described as the Waste and Resources Action Program. 3. The episode asks what actually drives household food waste and what households, businesses, and governments can do to cut it. 4. Claire says WRAP is a charity and not-for-profit headquartered in the UK and focused on food, plastics, and clothing and textiles. 5. She explains that WRAP works with End Food Waste Australia, which is tasked with delivering Australia’s national food waste target. 6. Claire cites a 2021 feasibility study that asked whether Australia can halve food loss and waste by 2030 and answered yes. 7. She says that target needs unprecedented action across government, businesses, and individuals. 8. Claire explains that food loss and waste happen across the whole supply chain, from farm to home. 9. She says household food waste is partly about home behavior and partly about upstream issues such as confusing date labels. 10. Claire contrasts used by dates, which are about food safety, with best before dates, which are about food quality. 11. She notes that a supermarket can sell three versions of the same product line, such as cheese, with different date markings. 12. Claire says about 70% of the food thrown away from Australian homes could have been eaten. 13. She gives examples including moldy bread, limp salad, sad carrots, and cheese discarded after a best before date. 14. Claire says the average Australian household wastes about $2,500 worth of food each year. 15. She says Australia’s supply chain is unusual for a developed nation because it wastes significant amounts in primary production, homes, and hospitality. 16. Claire points to the cold chain and says shutting refrigerated truck doors while unloading on a 40-degree day is one simple fix. 17. She says the hardest part is implementation, because behavior change is difficult even when the action is obvious. 18. The interview tone is practical and explanatory, with Gabriella Jastra asking for definitions and examples while Claire answers in structured detail. 19. Listeners interested in household budgeting, food systems, or practical sustainability will get the most from it. 20. Listeners wanting a fast entertainment segment without logistics or policy detail may skip it.
