Does anyone has inventory to model polyethylene glycol (PEG) in openlca? can i use ethylene glycol or triethylene glycol as proxy? (1 kg --> 1 kg?)  what do you think ? thank you!

Happy New Year indeed,

if you search on Nexus (https://nexus.openlca.org/search/query=polyethylene%20glycol), you will see that the CarbonMinds database has PEG datasets. However, using triethylene glycol is the proxy I would choose as it is closest to PEG. If it is just a solvent, I think you will be fine with this solution. If it ends up in your material, I would consider modeling the production of PEG yourself.

Hope this helps
