Mass Balance

Accounting Principle

Administrative tracking of sustainable or recycled content allows for the mixing of certified and non certified materials within a production process. The mass balance approach ensures that the volume of certified product leaving the mill does not exceed the volume of certified raw material entering it. This method supports the transition to sustainable sourcing when physical separation or distinct processing is not possible.

Credit Allocation

Many chemical and fibre producers use this system to allocate recycled credits to specific batches of product. Under mass balance rules, the actual molecules in a garment may not be the ones originally certified as sustainable. The system relies on rigorous bookkeeping and third party audits to maintain its integrity.

Operational Method

Credits are tracked through the manufacturing stages using a ledger or a software platform. A factory producing viscose might feed both certified wood pulp and conventional pulp into the same digestor while using mass balance to sell a portion of the output as certified. This allows for more efficient use of infrastructure compared to dedicated production lines.

Industry Adoption

Standard setters like the Forest Stewardship Council or the Global Recycled Standard allow this model for certain product categories. Reliable mass balance data provides a bridge for brands to meet their sustainability targets.
