BS EN 16785-2 is the second part of the multi-series standard that is applicable to bio-based products. BS EN 16785-2 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.
BS EN 16785-2 is applicable to any solid, liquid and gaseous bio-based product containing carbon, obtained by chemical synthesis, mixing or assembling, provided that:
Note:
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.
BS EN 16785-2 on the determination of the bio-based content is useful for:
The term ‘bio-based’ means 'derived from biomass'. Bio-based products (bottles, insulation materials, wood and wood products, paper, solvents, chemical intermediates, composite materials, etc.) are products that are wholly or partly derived from biomass.
BS EN 16785-2 sets the traceability system of the production unit to provide the necessary information and data to perform the calculations. This method requires that the bio-based content of each input and lost material for the defined product batch in the production unit is known.
Overall, BS EN 16785-2 provide a material balance method that will help you to determine the bio-based content of solid, liquid and gaseous products, based on the accounting of materials entering and leaving the system and on traceability of the materials during processing, to ensure the physical presence of the bio-based material in the output.
