As governments, industry and communities work to improve sustainability outcomes, attention often focuses on farming at one end of the food system and recycling at the other.
Yet between these stages sits the Critical Middle – the processing, packaging and distribution systems that connect farm to consumer and play a vital role in food security, emissions reduction and supply chain resilience.
A vital but often overlooked part of the food system
Food systems are increasingly recognised as essential to addressing sustainability and food security challenges. However, much of the conversation focuses on agricultural production and end-of-life management.
The Critical Middle – encompassing food processing, packaging, storage and distribution – is where many of the greatest opportunities exist to reduce food waste, lower emissions and strengthen resilient food systems.
As governments and industry look for ways to reduce emissions and strengthen food security, the Critical Middle presents significant opportunities to drive innovation and improve sustainability outcomes across the entire value chain.
Looking at the full picture
Tetra Pak's 2026 Life Cycle Assessment of Beverage Packaging in Australia and New Zealand found that 98% of a package's carbon footprint is generated before it reaches the shelf, while just 2% is associated with end-of-life treatment.
This highlights the importance of taking a whole-of-system view when evaluating environmental outcomes.
While these considerations are important, they can overlook the broader role that processing, packaging and distribution play in delivering food safely, efficiently and sustainably.
Current approaches can:
- Focus on individual materials rather than whole-system outcomes
- Under-recognise the role of the Critical Middle in food system performance
- Overlook the importance of material diversification in strengthening supply chain resilience
- Underappreciate the role different packaging formats play in enabling food preservation, shelf life and distribution
- Create unintended consequences if reforms do not reflect how food systems operate in practice
“Much of the sustainability debate focuses on what happens after a product is used. Yet some of the biggest opportunities to reduce waste, lower emissions, and improve food security exist in the critical middle of the supply chain. If we want better environmental outcomes, we need to look beyond end-of-life solutions”

Frequently Asked Questions
Packaging sustainability is about optimising environmental, economic and functional outcomes across the entire lifecycle of a package, from raw material sourcing and manufacturing through to transport, use and end-of-life management. Recycling is important, but a full lifecycle view is essential because most environmental impacts occur upstream in material production, package design and distribution, making a whole-system approach more effective than focusing on disposal alone.
Recycling and disposal represent only a small part of a package's overall environmental footprint, about 2%. Focusing solely on end-of-life overlooks larger sources of emissions and resource consumption that occur during material production, manufacturing, transport and food distribution. To achieve meaningful emissions reductions, decisions must consider impacts across the entire lifecycle.
The "Critical Hidden Middle" refers to the processing, packaging and distribution stages that connect food production with consumption. Despite being essential to food availability, affordability and safety, these stages are often overlooked in sustainability discussions. By improving efficiency and innovation in this part of the food system, substantial gains can be achieved in emissions reduction, food security and resource use.
Material choice and packaging design influence product protection, shelf life, transport efficiency and resource use, all of which affect environmental outcomes. Packaging that is appropriately designed for its purpose can reduce spoilage, minimise transport emissions and improve supply chain efficiency, while poor design choices can increase waste and overall environmental impacts.
Packaging plays a critical role in protecting food from damage, contamination and spoilage throughout the supply chain. By extending shelf life and enabling safe transportation and storage, packaging helps reduce food loss and waste while supporting reliable access to food for consumers.
A circular economy approach considers how packaging materials are sourced, designed, used, collected and recovered, rather than focusing solely on recycling. It aims to maximise resource efficiency while ensuring packaging continues to deliver essential functions such as food protection, product safety and supply chain performance.
Policies that prioritise recyclability without considering broader system impacts can unintentionally reduce packaging performance. In some cases, this may result in shorter shelf life, increased food waste, less efficient transport or greater resource use, potentially increasing overall environmental impacts despite improvements in recyclability.
Packaging supports supply chain efficiency by protecting products, improving packing and transport efficiency, and extending shelf life. These benefits help reduce product loss and food waste while lowering emissions associated with production, distribution and replacement of wasted products.
Different packaging materials deliver different performance characteristics and sustainability benefits depending on the application. Maintaining a diverse range of material options supports resilient supply chains, encourages innovation and helps ensure packaging solutions can be matched to specific product and environmental requirements.
Australia needs policy and decision-making frameworks that consider the full lifecycle impacts of packaging rather than focusing primarily on end-of-life outcomes. This includes recognising the role of the Critical Hidden Middle, applying evidence-based lifecycle assessment, and balancing recyclability with broader objectives such as emissions reduction, food security, product protection and supply chain resilience.
