I want to calculate the biogenic carbon content in my product using the OpenLCA. However there are a lot of processes that might have such an input in my product. How can I understand which of them affect the amount of biogenic carbon in my product, and next, how can I calculate it. I use the ecoinvent 3.8 and EuGeos 15804 databases.
Additionally, because my product is a construction product, there is a cut-off rule of 1% according to the EN 15804 standard, about the mass input. Does this also affect the biogenic carbon mass input, meaning that if it lower I can consider it negligible?
Thanks a lot for your time.
