This part of EN 16785 specifies a method of determining the bio-based content in products using the material balance applied to a representative product batch in a production unit. This European Standard is applicable to any solid@ liquid and gaseous bio-based product containing carbon@ obtained by chemical synthesis@ mixing or assembling@ provided that: ?? for a product batch@ the composition of the product and the bio-based content of each input@ output and loss in the production unit are known; and ?? the bio-based content of the product is verifiable by analysis. This method incorporates only the physical parts of the input and output stream as present in the final product@ and does not incorporate material inputs for the energy to be used during the production process. This method is not needed for the determination of the bio-based content in natural products wholly derived from biomass.
