Material Flow
The tracking of packaging materials through the entire supply chain from production to end-of-life. Understanding material flows is essential for accurate EPR reporting and identifying circular economy opportunities.
Material flow analysis tracks how packaging materials move through the economy — from raw material extraction through manufacturing, distribution, consumer use, collection, and recycling or disposal.
Understanding material flows helps producers:
- Accurately report packaging data through RPD
- Identify where packaging enters household vs non-household waste streams
- Estimate nation data splits based on distribution patterns
- Spot opportunities for lightweighting and material substitution
- Quantify recycled content throughout the supply chain
Material flow analysis is a key tool for businesses seeking to improve their circular economy performance. At a national level, the UK tracks aggregate material flows to set recycling targets and assess system performance. For individual producers, mapping material flows reveals where waste occurs and where interventions (such as eco-design changes) can have the greatest impact on both cost and environmental outcomes.
