War is changing the business case for circular packaging. For years, many packaging teams treated reuse, refill and higher recycled content as sustainability projects. Conflict has made them supply chain projects as well.
When war disrupts shipping lanes, raises energy prices or tightens access to raw materials, the weaknesses of the traditional linear model become harder to ignore. UNCTAD says freight rates stayed elevated and volatile in 2024 and 2025, with geopolitical tensions and trade disruption driving uncertainty across global shipping.

At the same time, the European Commission frames the circular economy as a way to reduce pressure on primary raw materials and build a more resilient, competitive economy.
That matters because packaging depends heavily on long, complex material flows. Virgin plastic, paper fibre, aluminium, glass inputs and transport capacity all sit inside international networks that can become more fragile during conflict.
Recent disruption in and around the Red Sea, for example, showed how quickly delays and higher freight costs can spill into packaging and recycling markets. The direction of travel is now clearer:
businesses want packaging systems that use fewer virgin inputs, keep materials in circulation for longer and reduce exposure to distant supply shocks.
Conflict exposes the weakness of linear packaging
A linear packaging model relies on a steady flow of virgin materials, predictable transport and low-cost disposal. War puts pressure on all three. Freight can become slower and more expensive.
Energy costs can rise sharply. Access to feedstocks can tighten, especially when petrochemicals or metals are caught up in wider geopolitical stress. UNCTAD’s 2025 review says freight market developments in 2024 and 2025 underlined the vulnerability of global trade to persistent disruptions, regulatory shifts and the Red Sea crisis.
For packaging buyers, this is not only a logistics story. It is a cost and continuity story. If a business depends on single-use formats made from virgin inputs sourced through long routes, it may be more exposed when conflict disrupts trade.
By contrast, recycled packaging, local recovery systems and reusable packaging can reduce reliance on fresh material extraction and repeated one-way transport.
The World Economic Forum said in 2026 that circularity is gaining force because supply chain disruption, material concentration risks and commodity volatility have exposed structural weaknesses in linear systems.
This does not mean war is good for sustainability. It means war is making resilience impossible to separate from sustainability. In packaging, that shift is important. Boards are more likely to support circular investment when it can protect supply, cut waste and improve cost control at the same time.
The International Chamber of Commerce and EY have also argued that fragile global supply chains strengthen the case for circular models that rely more on secondary materials and stronger local loops.
Circular models reduce material and freight risk
The strongest circular packaging models do three practical things. They reduce the need for virgin materials. They shorten or diversify supply chains. They create more chances to recover value after use. In simple terms, a pack that is reused many times, or one designed for easy recycling into new packaging, can lower exposure to the next external shock.
This is one reason sustainable packaging has moved beyond brand messaging and into procurement, operations and risk management.
The trend is visible in industry research. The Sustainable Packaging Coalition’s 2025 trends report said the sector has moved from discussion to action, with policy, design and recovery systems all becoming more central to packaging strategy.
The World Economic Forum’s 2025 work on circular supply chains also argues that circular systems can unlock economic value while improving resilience. Together, those findings point to a broader market lesson: circular packaging is becoming part of mainstream industrial planning, not a side initiative.
Reuse is especially relevant in a high-risk environment. Where it fits the product and logistics model, reusable transit packaging, refill formats and pooled assets can reduce repeated purchases of one-way packaging. Recycling matters too, but businesses are learning that recycling alone is not enough if packaging remains hard to collect, hard to sort or dependent on unstable export routes.
More companies are therefore combining recycled content goals with simpler pack design, mono-material formats and stronger take-back systems. Those choices can improve both packaging resilience and regulatory readiness.
Regulation and procurement are turning pilots into strategy
War may sharpen the urgency, but regulation is helping to lock the shift in place. In the EU, the Packaging and Packaging Waste Regulation entered into force on 11 February 2025 and will generally apply from 12 August 2026. The regulation is designed to reduce packaging waste and support reuse, recyclability and a more circular market.
The OECD also says extended producer responsibility makes producers financially responsible for the post-consumer stage of products such as packaging, helping fund collection, sorting and recycling.
That combination of regulation and geopolitical risk is changing procurement decisions. Buyers now have stronger reasons to ask how a pack will perform not only on cost and appearance, but also on supply security, recoverability and exposure to future disruption.
McKinsey’s 2025 packaging research shows that sustainability still shapes packaging decisions, even when affordability matters more than before.
In practice, that means the best packaging strategies are becoming more balanced: lower material use, better recyclability, more recycled content where feasible, and selective investment in reusable packaging where the economics work.
For B2B decision-makers, the long-term message is straightforward. War does not create the circular packaging shift, but it does accelerate it. Conflict exposes the financial risk of wasteful, linear packaging systems that depend on cheap transport and easy access to virgin materials.
Circular models will not remove every supply shock. They can, however, make packaging operations more adaptable, more resource-efficient and better aligned with tightening regulation. In a more volatile world, that is no longer a niche sustainability argument. It is becoming standard business logic.
