Our methodology
At the core of material flow analysis is a mix of data sources: propriety data that is granular to a packaging component level, producer responsibility submissions, import/export statistics, waste composition studies, and insights from recyclers and local authorities. Each dataset tells part of the story, but it’s the integration of these streams that reveals the bigger picture.
Of course, no dataset is perfect. Inconsistent reporting, incomplete records, and gaps in international trade data mean assumptions are sometimes needed. That’s why transparency in methodology is vital: stakeholders must understand where the data is strong, where the margins of error lie, and how trends are derived.
The PackFlow reports, produced by Valpak, draw on their Data Insights expertise and industry collaboration to ensure data accuracy and consistency. This work helps businesses and policymakers to better understand packaging flows and compliance risks.
Tools used
The methodology combines proprietary data, industry reporting requirements with independent research. Producer data provides the baseline, while import and export statistics highlight flows across borders. Waste analysis, recycling statistics and industry consultation then adds detail on what’s actually being collected and recycled. By triangulating these sources, the PackFlow reports provide one of the most comprehensive pictures of UK packaging flows available.
The results inform not only business decisions, but also government policy and wider circular economy strategies.
Looking ahead
Materials data is more than just numbers on a page, it’s evidence that shapes future regulation, drives compliance costs, and sets the direction for innovation. By addressing gaps and building stronger datasets, industry and policymakers can work from a shared understanding of reality.
PackFlow reports will continue to provide the evidence and foresight needed to support government policy and help industry adapt to evolving extended producer responsibility regulations.
