It's no mystery that landfill tiles absorb zero pollution. https://wiki.factorio.com/Pollution#De-polluters

However I've encountered some pollution spreading across a landfill island where there is no source. Please refer to the attached image. It's surrounding a location where there is nothing ...

They can't in vanilla.
However, if your need is "I want clean grid arrranged wires", there is this mod : https://mods.factorio.com/mod/power-grid-comb
This can help controling where the wires go to shut down more simply a column or a row of machines.
[Edit] Also the link to the related suggestion ...

I've just been directed to this thread after asking about whether or not blueprints are currently capable of recording copper wire arrangements.

I believe this should DEFINITELY be added as a feature. If the concern is over blueprints becoming "ugly" (as described earlier in the thread ...

I'm trying to create various arrangements that manipulate the flow of power through switches. IE some power poles are intentionally isolated from their neighbours for the purpose of correctly routing the power.

The problem is that the blueprints don't record this specific arrangement of power ...

interesting.

I think, that letting the miners back up would be much better.
Pollution seems to be a problem for you, but having 30% more output for the pollution of 4 miners seems very inefficient.
Compared to 3xEff1 miners it gets even worse.
One of your miners produces as much pollution as 17 ...

Worked it out. A new combinator is needed in the circuit so that the T counter is interrupted whenever [Everything] != 0 . IE any resource is passing through the belt counter.

This approach has worked very well, but with one drawback: the decider combinator has to be set to whatever ore type is being mined. If it's not the ore in the blueprint then I need to wait for the bots to place the combinator before I can change it. That gets tiresome after a while.

This sounds ideal, plus I'd also like to see trains replaced if they are attacked & destroyed.

I very much enjoyed Factorio's introductory campaign. Not only did it work well as a tutorial, but the story was engaging as well and made you feel in touch with the world of the player.

Something I expected, that never materialised, were Non-Player Characters. Partway into the early campaign ...

Tried that in the past but still killed off trees and aggro'ed the locals.

Not in a position to give you a blueprint just now, but:

Two decider combinators, one constant combinator.

Constant: T = 1

Decider 1: If [iron, copper, whatever] = 0, output T (input count)

Decider 2: If T > 60, output Red (1)

Wire a belt (read input, hold) to Decider 1's input with green wire ...

Hi!

(First post)

I've been trying to find a forum thread that explains belt counters in detail. I want to create a trigger for when the flow of materials on a belt completely ceases (the primary reason being to alert me when mines run out). The nearest I've come to a solution in the image below ...
