How I can change another scrap recycling?
Help pls. Coal is great, now I want to change ice to sth another, better if I will know how to write it by myself, but If you want to just made another mod for ice changing I won't complain...

The replacement from solid fuel to coal should be optional, and ice should still be in the scrap recycling recipe; if not, that's a bug.
If you want to replace the ice with something else, I could create another small mod. But I would be fine if you do it. I can teach you using my library mod, since it already has all the functions you need. If you are interested, you can contact me via Discord for faster correspondence.

oc1024 in discord doesn't work to find channel or user

Hm, but that's exactly my username there.
I'm on the https://www.discord.gg/factorio server as well. You should find me there, too.
You can add me as a friend as well.
