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.
