I've never used openLCA before and I am trying to calculate a product system, but one of my processes does not contribute to the results.
For some specifics:
- I'm using the LCA Commons (US) dataset for plastics product manufacturing [injection moulding, PP]. One input for the injection moulding process is PP resin. I changed the amount of the PP resin output to 3.48 kg.
- The LCIA method I want to use is Eco-Indicator 99 (H,A)
- When I look at the impact analysis section of injection moulding, all results are 0, which doesn't seem correct to me
- I calculated the entire system flows (injection moulding + transportation) and the results of doing that only take into account the transportation
Please let me know if I'm doing something wrong! I'm not sure what I need to do differently and I need to have these results as soon as possible. Any help will be greatly appreciated!
