The global packaging industry is making strides in recycling and design, but it’s still grappling with a big issue: the balance between packaging waste and food waste. Nerida Kelton, VP of sustainability and safe food at the World Packaging Organisation (WPO), shared insights at Interpack 2026 about how Extended Producer Responsibility (EPR) regulations are changing the game worldwide.
A Balanced Perspective
Kelton emphasizes that WPO doesn’t favor any specific materials. This impartial stance is crucial because they’re not influenced by commercial interests. However, she challenges the notion that plastic is always the bad choice. “We need to ensure that our packaging serves its purpose, such as food safety and shelf life,” she notes. In certain cases, polymers are still the best option available.
Kelton insists on educating both consumers and industry players about the unique roles of various materials in packaging.
Changes in Packaging Design
A significant shift is happening: the industry is starting to design packaging with its end-of-life in mind. This means that using fewer materials and creating recyclable options are becoming priorities. “We’re learning to reduce our waste from the design stage,” Kelton explains.
For instance, integrating recycled content into food-grade materials is gaining traction, which can help reduce waste further. Kelton stresses that brands need to understand exactly what happens at the end of their packaging’s life. “You have to know if it will be recycled or end up in a landfill.”
The goal? Achieve a circular economy where materials can be reused as much as possible.
Rethinking Fiber Alternatives
There’s an ongoing conversation about replacing plastic with fiber-based solutions. But according to Kelton, decisions can’t be made solely based on popular opinion. “We should base our choices on life-cycle data,” she argues.
For example, consider fresh produce packaged with paper versus plastic. Factors like shipping distance and climate can affect which material to use. In Australia, products like tomatoes travel long distances and require durable packaging. We must ensure consumers don’t end up with spoiled goods.
The Food-Waste Dilemma
One of the main challenges the industry faces is balancing food waste against packaging waste. Kelton highlights this trade-off, stressing that it’s essential to optimize packaging without wasting food. If food goes bad due to inadequate packaging, the environmental costs are significant.
Each company needs to reconsider its trade-offs in packaging design and sustainability. This includes not only the materials used but also the entire supply chain, from farm to fork. Understanding the customer’s needs—like packaging ease—can play a big role in reducing waste too.
Hidden Waste Sources
Kelton also points to overlooked areas of waste, particularly in secondary and tertiary packaging. “There are opportunities for cost savings and less waste in areas like warehousing and logistics,” she says.
Efficient pallet packing and stacking in cold-chain transport are crucial. If done poorly, it can lead to spoilage and increased losses, showing the need for more training in these processes.
Looking Ahead
By the next Interpack in 2029, Kelton hopes for greater consistency in global packaging standards and more open discussions about food safety and waste. These topics must be elevated in the industry dialogue, making sustainability a priority.
Overall, the path to sustainable packaging is complex, requiring careful consideration of various factors. As we move forward, a focus on collaboration and informed choices will be vital for creating a more sustainable future.
