saving ** M ass-balanced products are products where traceable bio-based raw materials or primary products have been used in the production process within a specified scope without biogenic carbon being reliably detectable in the final product. Mass balancing is a bookkeeping method (e.g. for the proportion of recycled materials) used to record and track mass flows of plastics along the entire value creation chain. This allows sources of fossil-based raw materials to be removed from the production process, for example by removing CO2, biomass or secondary raw materials from chemical recycling. As the mass balancing approach is a bookkeeping method, the exact percentage of recycled material in the product cannot be determined precisely.
