WHAT HAPPENS BEHIND THE FRIDGE DOOR:
UNDERSTANDING HOW HOUSEHOLD FOOD WASTE OCCURS

KEY HIGHLIGHTS:

• Simple changes in everyday​ routines (i..e. how we shop, store,​ and cook) and better household understanding of fridge​ temperatures and storage​ zones could significantly​ reduce meat waste at home.
• ​There are opportunities for manufacturers to tailor fridge and freezer designs to household needs, improve temperature controls and alerts, enhance storage guidance, and strengthen product stewardship through co-design​.
• Findings are already informing refrigeration design and manufacturing, strengthening how industry responds to consumer motivation to reduce waste.

In many Australian homes, food waste continues quietly tucked behind fridge doors, forgotten on shelves, or spoiled sooner than expected. While attention is often placed on supply chains, the role of everyday household practices and appliance performance in driving food waste has remained less visible and poorly understood. Each year, significant volumes of meat are wasted often driven by uncertainty around freshness, storage and everyday routines.​

How can households reduce food waste through better fridge management?

​To better understand this, the project on consumer fridge practices and waste reduction of red meat took a closer look inside the home. Researchers worked with households across Australia to monitor fridge temperatures while also conducting interviews and engaging with householders to understand everyday routines – how people store, portion, cook and assess which food becomes waste.​

​What emerged was an important insight that food waste is not just about individual behaviour or appliances. It’s about how the two interact. Many fridges and even individual shelves operated outside ideal temperature ranges, while everyday routines unintentionally accelerated spoilage.​

How are these research findings about consumer fridge practices helping reduce food waste and inform industry?

​Looking ahead, the findings are already informing industry standards and interventions that support low waste at the household level and how fridges can be made to operate more effectively.​

As the research suggests, understanding what how fridges and everyday routines of people interact may be one of the most powerful levers for reducing food waste at home.
