Traceability Files That Release a Detained Textile Container
Releasing detained textile containers requires an audited dossier pairing transaction certificates with mass balance scrap calculations and IRMS origin testing.
Mass Balance Yield Math
Calculation Logic
Accounting methods used in sustainability programs track the volume of certified material as it moves through a complex supply chain. The application of mass balance yield math involves subtracting the known waste percentages from the input of raw fiber to predict the final output of finished goods. This system allows mills to mix certified and conventional fibers while still making accurate claims about the total volume of sustainable material produced.
Material Tracking
Records must show that the amount of certified product leaving the factory does not exceed the amount of certified raw material that entered it. Under the rules of mass balance yield math, the factory accounts for losses that occur during spinning and weaving or dyeing and finishing. This ensures that the environmental benefits of the certified fiber are correctly attributed to the final garments and not counted twice in the system.
Proportion Attribution
Credits are assigned to the output based on the percentage of sustainable material in the total production mix for that month. Because mass balance yield math ignores the physical location of the fibers within the yarn, it allows for more efficient industrial processing. Brands use this data to report their progress toward sustainability goals without needing to segregate every batch of fiber in the warehouse.
Certification Credibility
Valid calculations prevent the overstatement of sustainable content in a global inventory of textile products.
