The mass balance principle means that we sourced and allocated an amount of recycled material that meets ISCC's certification requirements, in order to produce the new Cadbury tablets packaging wrapped in 80% recycled plastic. The mass balance approach makes it possible to track the amount and characteristics of circular material in the ISCC certified value chain and attribute it based on verifiable bookkeeping.

When the mass balance principle is used, the physical amount of recycled plastic in the packaging can vary. We attribute an equivalent amount of 80% recycled plastic, but the physical amount of recycled plastic can be more or less.
