Hi Fei, thanks for getting back to me. Interesting post on recycling. However I don’t believe this is the issue – it still seems like a bug with the bulk swap tool.

I found it wasn’t working for steel so I tried multiple different materials. Changing the recycled content of a material shows no change in all of the impact categories in the swap summary chart (before you actually apply changes) – it seems like a bug in the bulk swap tool, because when you manually edit templates and change recycled content then it will affect the impact categories (although doing it this way sometimes shows a strangely small change, so it also seems a little buggy).

For using material swap instead, I don’t see an option for a high recycled content steel.
