Hello!
Thanks for the update!
Perhaps a script variant for towers to get a cleansing radius is described here, but since I am not a modder, unfortunately I cannot try to do it.

I also noticed that there is no recipe for cleaning "bery0zas-polluted-spray-surface", and it turns out that the cycle does not complete, because the item at the end remains unused anywhere

Yeah, the problem is in the recipe name, because apparently in the basic version the recipe name coincides with the recipe for the recycler.

Heh...
Any volunteers to test how the cleaning of neighboring chunks works? :) I don't have a large database, so I can't check the performance.
I will provide a version with this function.

It is still on a todo list. The list is just very long ... :(

Oh, no, I mean, I implemented this feature. If you want, you can test it. I also tweaked some other things, but I don't remember anymore since I'm not playing Factorio right now. I think it was some recipes and icons for them.

Any update for 2.1 in mind?

When 2.1 hits stable.

New version has an option to switch between native pollution handling and a scripted version. I also added circuit connectors and the rotation now preserves the selected recipe. I also added your Badges for items and tiers.
