... by multiple recipes [LDS], some items are produced by a common recipe [scrap recycling])

Because of that i am against this suggestion because it would add a "sometimes works" feature. Given how much of "sometimes works" blueprint parametrisation already is and how many bug reports this causes, i ...

This was implemented in Space Age / Quality mod. I wonder if it is a record for longest “Suggestion-to-Implemented” wait time?

... them from, they are a vital tool for disposing of excess stuff so that scrap recycling can continue. I don't think it's unreasonable to argue that disposing of unwanted items is one of the main things recyclers exist to do.

So having Aquilo depend on recyclers to be able to dispose of unwanted ice ...

Welcome to Fulgora.

Quality Holmium Ore serves no purpose and is just a contaminant when it comes to recycling with quality modules. For QoL, any Holmium Ore that would have been produced at a higher quality should either be voided, replaced with common quality or replaced with >1 common quality.
Yes, we can deal with it ...

I am strongly against this.

There are two types of recycling:

I am absolutely convinced that this is not a nerf to concrete recycling but a buff to quality iron production on Fulgora.

However, I would ...

This is my design to take only the two native Fulgora resources (scrap and heavy oil) and turn them into rocketships full of EM potions. Here are the factory specs: (my scrap recycling tech is at level 25)

Inputs: two fully stacked belts of scrap (480/s) and two ports for heavy oil (<500/s each ...

I am currently processing something like 35+ stacked turbo belts of scrap on Fulgora without using this trick (or any other trick). There are people ... so dense. Certainly I agree that hazard concrete should have the same recycling recipe as regular concrete.

But from a neutral perspective on the ...

... Was anyone sitting around cursing hazard concrete for making concrete recycling more efficient? Scrap processing was still roughly 40% item voiding by building count, it's hard to argue hazard concrete recycling was unbalanced in any way. It wasn't an unprecedented mechanic either; not only are there ...

End products don't go through logistics, except for recycling and immediately re-crafting until the desired quality is reached.
Fulgora produces most items directly from scrap recycling, which effectively accepts mixed quality input due to internally functioning as a furnace ...

TL;DR
Since 2.1.7, recycling hazard concrete, instead of outputting normal concrete, produces the same outputs as recycling normal concrete. This ... hazard concrete.

Why?
Literally every item in the game, other than scrap, either recycles to its ingredients or recycles to itself. Now, randomly ...

I just built a "Final Fulgora" setup that takes in only scrap and heavy-oil and only outputs rockets full of electromag potions. For the concrete recycling I just did cargo bays and it worked great .. one of the easiest parts of the design in the end. You just need to set up steel and ...

... item, it would wait in the recycler's output slots.

With quality and recycling scrap, this would create an issue of insufficient output slots and clogging the machines, as the recycler would need up to 60 output slots for each item waiting to reach a count of 4. The solution would be to use dynamic ...

Did they change the recycling speed too, or will recycling hazard concrete dump those raw ingredients much faster than for concrete?


Actually, I've ... According to the wiki :

The recycling recipe for an item, other than scrap, is equal to 1/16th (0.0625) of the time it takes to craft that item ...

Here is my end-game scrap processor:
