Weight-Based Reporting
The EPR requirement to report packaging data by weight in tonnes or kilograms rather than by unit count. All fee calculations are based on tonnage, making accurate weight data essential.
Weight-based reporting is the requirement under pEPR to report packaging data by weight (tonnes or kilograms) rather than by number of units. All fee calculations, PRN obligations, and recycling targets are expressed in tonnes.
Weight reporting requirements:
- Report by material type — weights of each material separately
- Include all components — caps, labels, sleeves, etc.
- Separate household from non-household weights
- Split by UK nation
Accurate weight data starts with good packaging specifications. Producers should weigh representative samples of each packaging format using calibrated scales. For multi-component packaging, each component should be weighed separately if made from different materials. Many businesses underreport weights by overlooking small components or ancillary packaging. A sampling methodology should be used for products where individual weighing is impractical.
