Waste Factor (%)
Waste is the loss of input incurred to produce the required output in a given production process. Waste is incurred at every level of the textile value chain. The Waste Factor is the multiplier applied to the output, to account for the waste for a production process, to estimate the input. Fiber weight is used as a baseline for reporting in the Textile Exchange PFM Benchmark, and three Waste Factors have been assumed for converting product, fabric and yarn to fiber within four PFM categories: preferred cotton, recycled polyester, preferred man made cellulosics, and preferred down.
