For a research project, I am trying to compare the environmental impact of virgin and recycled construction materials based on existing EPDs. Here is the method that i followed:
1. I created a new impact assessment methods including only the two impact categories that are relevant for my analysis,
2. I created "Results" based on publically available EPDs for construction material (for the different modules A1-A5), specifying "impact assessment results" for each impact category of the method, and created the corresponding "EPDs".
2. I created an associated product flow for each EPDs created
3. I created a process having the created flows as input and generated the associated product system, and my idea was to calculate the environmental impact based on the results entered for the EPDs. The environmental impact is equal to zero so I guess the strategy wasnt correct.
Briefly, is there a way to integrate the impact assessment results of EPDs into an impact assessment of a product system with the version 2.0?
Thanks a lot in advance,
