Small-format, flexible plastic packaging—such as sachets and candy wrappers—represents one of the greatest systemic barriers to ending plastic pollution globally. According to an official report by the Ellen MacArthur Foundation, paper-based flexible packaging could be a promising alternative to tackle the issue, but it is not a silver bullet. The transition can only be sustainable and economically viable if it strictly adheres to the principles of the circular economy and utilizes responsible design that meets six stringent criteria.
The global fight against plastic waste is increasingly focusing on small-format, flexible packaging. These materials are almost entirely non-recyclable or extremely difficult to recycle within current waste management systems. The Ellen MacArthur Foundation’s report, “Paper as a solution to flexible packaging pollution,” examines paper as one of the most important potential substitutes, while also issuing serious warnings to policymakers and corporations.
The Potential of Paper and the Three Pillars of the Circular Economy
According to the report, one of the greatest advantages of paper-based flexible packaging is its dual environmental safety: with adequate collection systems, it can be recycled at a high rate, while also being biodegradable in a worst-case scenario where it inadvertently ends up in nature.
However, experts at the Foundation emphasize that simple material substitution alone is not enough to solve the problem. The solution must be built on a complete, design-led circular economy model resting on the following three core principles:
-
Eliminate waste and pollution through design.
-
Circulate products and materials at their highest value.
-
Regenerate nature and natural systems.
As part of this comprehensive approach, dependence on small-format, single-use packaging must be minimized, and reuse, refill, and packaging-free models must be scaled up globally.
The 6 Essential Criteria for Responsible Design and Implementation
One of the most critical findings of the report is that paper-based packaging must be responsibly designed and sourced to avoid merely swapping plastic pollution for another environmental problem (such as deforestation). The new paper-based alternatives must meet the following six strict criteria:
-
Responsible sourcing: Raw materials (wood fibers) must be sourced sustainably, avoiding any contribution to forest degradation or deforestation.
-
Responsible production: Manufacturing processes must minimize pressure on climate and water resources, with a strong focus on reducing greenhouse gas emissions.
-
Practical viability: Paper packaging must fully meet technical, economic, and consumer expectations to remain viable and functional in everyday commercial practice.
-
Local recyclability: The material must be genuinely recyclable in local systems, and the transition must be supported by scaling and improving the existing collection infrastructure.
-
Avoidance of harmful chemicals: The packaging design must strictly avoid hazardous chemicals and prevent the creation of persistent (e.g., microplastic) pollution.
-
Social inclusion and circularity: The solution must organically fit into a broader, socially inclusive circular economy strategy.
The Technological Gap and Infrastructural Investments
Reflecting industry realities, the report warns that there are currently no commercially available packaging materials on the market that fully meet all six criteria at the necessary scale, cost level, and expected performance.
Furthermore, the material transition is not just an engineering challenge, but a social and infrastructural one. The Foundation highlights that the introduction of paper-based solutions must be carried out in parallel with investments in inclusive collection and recycling infrastructure. During this process, special attention must be paid to protecting the livelihoods of informal waste pickers, who play a crucial role in waste management in developing regions.
A Call to Action for Policymakers and Innovators
Since a perfect mass-market solution is not yet available, the report calls for decisive action from the business sector and political decision-makers. The current gap between ambition and market-ready packaging should not deter stakeholders; on the contrary, it should accelerate innovation, piloting, and investments to quickly establish the safeguards necessary for the responsible use of paper-based flexible packaging.
