Hello, I am working on an open-LCA study for algae biomass production, specifically capturing CO₂ from industrial flue gas using microalgae to produce algae biomass. I used the TRACI 2.2 impact assessment method to evaluate the environmental impacts. I have completed a full LCA and obtained results, but I need clarification on result interpretation and material quantification. I'm unsure if my modeling approach is correct, and I would appreciate guidance on the following questions. I am struggling to interpret the results and would be grateful for any insights.
How can I determine if my process results in a net reduction in GWP compared to a baseline? What indicators should I check in openLCA?
- My materials (e.g., polyethylene for conveyor belts, steel for structures) are currently modeled based on their mass in kg.
- Should I normalize material usage per functional unit, such as per hour of operation or per year of system lifetime?
- How do LCA studies typically handle construction material allocation when modeling continuous processes like algae production?
Any suggestions or corrections will be welcomed
Thank you
