How can I calculate the amount of biogenic carbon in my product?

Question

I am doing an LCA on a wood-plastic composite for my thesis. My supervisor wants me to calculate the amount of biogenic carbon stored/fixated in the product. Is there any way I can calculate that in openLCA? I am using the EF and ELCD databases.

Answer 1

Yes, you can check the uptake of CO2 as resource that goes into your product, you see this in the contribution tree.

- regarding the EF and ELCD database, see my other reply please

If I use the "greenhouse gas protocol" or "selected LCI results additional" impact analysis methods there are impact categories for CO2 uptake and carbon biogenic fixed. Do you mean those?

You can simply use the flow, CO2 as resource in air.
