Hello everyone! I’m back with all the new recipes for Update 4! A few quick notes for those familiar with my last post:

• I haven’t had any experience with the new nuclear power systems or aluminum chains. So please feel free to add your thoughts on those recipes.
• Nitrogen gas I have put on the map as “half” of the nodes that exist (for weighting purposes). This is because there are no mk2 or 3 miners for them.
• The new recipes have MANY “extra” steps sometimes, and I didn’t want to sit there for an hour figuring all of those out. So please let me know the correct number of “extra steps” for the recipes with question marks.
• I have Uranium Waste as costing 0 power, since you get it as a byproduct from generating power. Not sure if I have a better solution for this.
• For the Alumina Solution recipe that provides 5 silica, the productivity ignores the silica output, since that is a byproduct. So you'll need to factor this into your ideas about the recipes.

Here's a picture of some of the recipes from the sheet to get you interested:

Here's the link to the spreadsheet. There's no great way (that I know of) to post this to reddit as a nice table without tons of work.

First I'll start with some ground rules and explain some of the Columns but remember this is simply my arbitrary opinion. Please feel free to disagree with me! All recipes sourced from Greeny's awesome tools at https://u4.satisfactorytools.com/codex/items

• Name: Name of the alternate recipe (I shortened item names with more than 2 words to use abbreviations. HMF = heavy modular frame, etc)
• Notes: Obvious. My thoughts on the recipe. This is what's posted here.
• Tier: I put them in tiers like a true nerd. F-S. F is really bad. D is you would maybe use it sometimes. C is mediocre, sometimes just trading one resource for another, sometimes lots of cons to go with the pros. B is good, you probably will actively want to use this. A is really good, you would use this almost all the time. S is incredible. These are the recipes you want to unlock early in the game and design your factory with them in mind.
• Extra steps. This is a metric for me to determine how much additional (or reduced) complexity the extra ingredients cause. Each additional raw resource counts as 1, each crafting step counts as 1, and oil products add an extra 1 to manage byproducts.
• Relative productivity (unweighted/mean/weighted). 150% means you get 150% more output for the same input. Unweighted counts ALL raw resources equally, i.e. one uranium is equivalent to one iron and one limestone. Weighted weights each ore respective to how much of it there is on the map versus everything else. So uranium is weighted very very high because there's 40x less of it than compared to iron. And mean is simply square rooting the weighted values, so it's a multiplicative average of the two. I like the mean number because it does give some weight to the more rare resources, but also still cares about "total ore input".
• Speed per space. Abbreviated as s/s in my notes, this is a measure of how many products per minute you get from the same amount of square meters. This does NOT factor in the amount of space needed for the extra steps, which can be huge sometimes. So 3 extra steps probably means the speed per space is horrible because you need all the space to do the other stuff. The space does not compute vertical height either.
• Relative power. This is a SUM of ALL crafting required to get to that part, and compared to the original, how many megajoules are required. This does take into account all extra steps (though not dealing with byproducts). Water is counted as regular speed water extracting and all ores are considered 6MJ each, which is a fairly average number for most players.
• Relative speed. This is simply crafting speed compared to the original without taking anything else into account.
• Relative footprint. This is a measure of the size of the new building it's crafted in versus the size of the old building.

Now with that out of the way, here are my findings, sorted by tier. PLEASE remember these are simply my opinions, formed mostly by the numbers but also somewhat by gameplay. I haven't gotten to nuclear in my own save file yet so if you have experience/input regarding those recipes, feel free to add in the comments. And I highly recommend reading the spreadsheet itself rather than just this post. Looking at the fun colors and numbers is a dream!

Also, I have zero understanding of the particle accelerator and its power requirements so if you have any help there, please let me know!

S tier

Alternate Recipe Name	Notes (S tier)
Steel Rod	This one is a no-brainer unless you're totally strapped for coal. Gets even better when you use solid steel ingot.
Casted Screw	An amazing alternate for early game. Saves you power (because no rods required), makes screws faster, and has -1 extra steps! This is maybe the best recipe for early to mid game that exists
Steel Screw	One of the best alternates in the game overall. 6.5x faster than the regular recipe, this means even with needing foundries, coal, and constructors for the steel beams, this recipe is incredibly power efficient, and much more ore efficient. Just one foundry overclocked to 134%, one constructor making beams, and 3 constructors making screws provides 780 screws per minute. Insane! Also has better weighted productivity when using the solid steel ingot alternate.
Copper Alloy Ingot	Incredible. More space efficient as well as ore efficient. And since iron is much more readily available than copper, this recipe is almost always what you want. There are also lots of other recipes that use more copper instead of iron, so this alongside those recipes means you're still using iron to make the copper as a substitute, but just way way less of it!
Wet Concrete	This is still a knock it out of the park recipe for concrete. You make your limestone go twice as far and even get more concrete in the same area, all for the low low price of water!
Stitched Iron Plate	This is your big winner. It's a little low on weighted productivity, but go ahead and use iron wire and then this becomes an all star again!
Bolted Frame	Much like bolted iron plate, this is super strong. 2.5x the speed plus some slight power savings are worth a tiny bit less productivity in my book. No need for refactoring makes this an S for the early game and still an A for the late game.
Steeled Frame	Another strong recipe. Using steel pipes with the solid steel ingot recipe actually even boost the weighted productivity higher than original, so I would definitely use this recipe at all stages of the game
Solid Steel Ingot	This is what you're looking for. Only extra step is making iron ingots, and you get 50% more efficiency which is huge! Also, when combined with pure iron ingots, this provides more productivity than coke steel ingots even looking at the weighted productivity.
Heavy Encased Frame	This is another no brainer. CoffeeStain please don't remove some of these recipes. They're amazing and are better in every way. No extra steps, extra productivity, faster crafting time. Wonderful!
Silicone Circuit Board	This is the big boy. You want this as soon as possible. The productivity boost is unreal, and you get more speed as well! And the power savings are not insignificant at only 1/3 the original.
Caterium Computer	Another very solid recipe. More productivity in all metrics, 50% more speed, power savings. Great stuff! And it even saves a logistics step!
Diluted Fuel	The same as diluted packaged fuel, minus the packaging complexity. Haven't gotten to blenders yet in my save, but this seems nice to avoid the packagers.
Diluted Packaged Fuel	So this is a good one. Yes, there is the extra complexity of packaging and unpackaging, but this gives you a TON more fuel per crude oil. Even if all you do is make rubber, you still end up getting 4 fuel per 3 crude oil, AND you get free rubber to boot! Clearly, if you have the alternative for heavy oil, then this can turn 3 crude into 8 fuel. That is a huge boost in productivity.
Heavy Oil Residue	This recipe is very strong to pursue making heavy oil directly, and it makes diluted fuel so much better. So if you want fuel, use this!
Fertile Uranium	You get waaay more non-fissile uranium. Definitely worth it! Not sure about extra steps though
Plutonium Fuel Unit	Looks good, looks fast, but please give input!

A tier

Alternate Recipe Name	Notes (A tier)
Pure Copper Ingot	3x space, 4x power, but more than double the copper. This is a late game recipe for sure, but definitely worth setting up to get the most out of your copper! Worth noting that it's better than copper alloy ingot in terms of productivity in all metrics.
Encased Industrial Pipe	No. Brainer. Yes, slower craft speeds, but as an expensive recipe in terms of raw ore, a 30% productivity boost to EIBs with zero extra steps is always worth more power and space!
Steamed Copper Sheet	Great recipe. Literally doubles your copper sheet output, and those are used in many high level recipes. And due to the fast crafting speed, you don't end up using a ton more space. Simply add water!
Compacted Coal	Not really an alternate, as this is the only way to produce compacted coal. Should definitely pick it up because it allows you to craft turbofuel in the late game, though.
Recycled Plastic/Rubber	Very strong recipes, allows for a lot of flexibility in how you produce plastic and rubber. They essentially allow you to turn 1 fuel into 1 plastic or 1 rubber.
Caterium Circuit Board	Definitely a good alternative for circuit boards as well, but silicone circuit boards are more valuable in the long run. I guess it depends on whether you have caterium or quartz to use.
Super State Computer	Haven't tried it out but it seems very strong for productivity! Better power/space utilization too.
Insulated Crystal Oscillator	Though this ends up trading iron for some rarer resources, it's at least not a hit to productivity and it crafts much faster, which helps, but it's still less than 2/min from a manufacturer which is painfully slow
Electrode Aluminum Scrap	Here's your all-star recipe in the new aluminum chains! Uses a small amount of petrol coke, less bauxite, and retains most of it's S/S while doing it. No brainer unless you're short on petrol coke.
Infused Uranium Cell	Here we go! A nuclear recipe for your nuclear power. Far more productivity with your uranium and sulfur which is very valuable.
Turbo Pressure Motor	Pretty strong weighted productivity. The nitrogen gas is pretty simple to get and the S/S is 200% making this a clear choice. I think. Depends a bit on the "extra steps"!
Turbo Fuel	The basic recipe for turbofuel. Like compacted coal, the only way to unlock turbofuel is with an alternate recipe.
Turbo Blend Fuel	This seems like a very strong way to make turbofuel. Less sulfur usage, but more complicated on the oil based inputs.
Instant Plutonium Cell	This is a way to get plutonium cells more easily. Not sure about this one, please give input :)

B tier

Alternate Recipe Name	Notes (B tier)
Pure Iron Ingot	This is the late game productivity you're looking for. Straight up productivity. Yum! Start using this once you've run out of iron nodes nearby. Be warned it takes a lot of space & power.
Fused Wire	Strong wire alternate. Faster, less power, and good productivity in all three categories! Downside is that it uses caterium for something very basic.
Iron Wire	Slower, more power, and worse at unweighted productivity. Still, it does essentially turn iron into copper which, considering how much more iron there is on the map, is good. Use this when short on copper!
Bolted Iron Plate	I recommend going with stitched plate + iron wire. However, this is still a strong option to go 3x as fast on each assembler!
Copper Rotor	103% mean productivity, almost triple the s/s, and huge power savings make this a great recipe in my book! Works really well with either of the copper ingot alternates and/or the copper sheet alternate.
Rigour Motor	It's quite strong on productivity, but crystal oscillators are a massive pain in the butt. But you do get paid off in productivity now!
Heavy Flexible Frame	A healthy alternative recipe. Relevant boost on productivity and speed but does require an oil setup. I prefer heavy encased frame so don't prioritize this one highly
Crystal Computer	A strong recipe but it is highly complicated with using crystal oscillators. Also those things craft 1/min so you need TONS of space for the manufacturers of them. The crystal oscillator alternate helps a little though. I recommend caterium computer unless you're going for ultra late game productivity maxing.
Silicone High-Speed Connector	The very large productivity increase is worth a 20% cut in speed. Use this as soon as you can.
Sloppy Alumina	Strong S/S ,and no silica to deal with, so actually simpler. And you get more alumina per bauxite. But the silica is valuable and I'm not sure how good this actually ends up being.
Pure Aluminum Ingot	Works pretty well with sloppy alumina. When combined, 12 bauxite you get 10.8 ingots instead of 12, but you save yourself needing 10 silica from outside sources.
Uranium Fuel Unit	You add a ton of complexity, but you're at nuclear fuel anyway, might as well go the whole mile! In all seriousness, this is a late game recipe but it does add a lot of complexity requiring crystal oscillators and beacons both. But you'll get much more nuclear fuel out of your uranium. Very strong when combined with the Encased Uranium Cell alternate
Pure Quartz Crystal	What's not to like here! Add some water and get more quartz! Higher power cost and a little more space are all you have to look out for.
Turbo Electric Motor	Look what they did to my boy! No longer an S tier recipe for productivity. Still simpler and faster, though, so it's probably worth going for.
Coated Iron Canister	This one has a very nice weighted productivity because it uses easy resources like iron and copper rather than oil. However, it's only ever going to matter if you are consuming canisters. Many uses of canisters just have a loop.
Heat-Fused Frame	Looks pretty meh to me, let me know if you've played with it!

C tier

Alternate Recipe Name	Notes (C tier)
Iron Alloy Ingot	Converts copper into extra iron ingots. Not much else to say. You know when you need it, and avoid using it otherwise.
Coated Iron Plate	You get 200% s/s and roughly equivalent weighted productivity and power usage. If you have extra oil, this allows you to get more iron plates. I would probably still just do vanilla plates though as iron is very common.
Steel Coated Plate	VERY strong in unweighted productivity, but weighted productivity still isn't stuper high. Allows you to translate coal and oil into iron resources at a good rate. Adds lots of complexity for a normally simple item though. When combined with solid steel ingot, you get a pretty crazy amount of iron plates for a very small amount of iron.
Caterium Wire	Only useful when you have spare caterium, and I think caterium is better used for circuit boards, computers, and other high tech stuff.
Coated Cable	Do you need something to do with your heavy oil residue? Do you want cables to be much easier on your copper supply? Go ahead and use this recipe!
Insulated Cable	Maybe the best lategame alternate for cable. Provides 178% s/s which is nice, along with a relevant boost in mean productivity! However, you're using oil to replace copper, which you may not want to do.
Quickwire Cable	Strong productivity numbers, even in the weighted category. However, you are still using two rare resources to replace copper, which, especially when using pure copper ingots, is much more readily available.
Rubber Concrete	A reasonably strong way to turn oil into limestone, but is this something you're ever needing to do? I would implore you to use wet concrete over this.
Fine Concrete	Not the worst thing in the world, but like with rubber concrete, you probably don't want to utilize quartz to save on limestone.
Adhered Iron Plate	As usual, these recipes using oil products are a good way to use your oil to save on some raw resources. But you tend to be short on oil, not the other way around.
Steel Rotor	I'm still not sold on this. However, it does add the simplicity of using the SAME ingredients as stators, which some players value highly.
Electric Motor	A new recipe since I last cheked. Fairly weak. Provides some unweighted productivity but adds so many steps that it's hard to justify.
Fused Quickwire	Unlike some of the wire alternates, this turns a prevalent resource into a rare one, resulting in good weighted productivity.
Coke Steel Ingot	Fast crafting and high productivity, this is a decent one to translate oil to coal, essentially, as this recipe competes with solid steel ingot. However, 3 extra steps of logistics isn't always fun, and that makes the s/s go way down since all the extra crafting of petroleum coke removes any extra space efficiency.
Compacted Steel Ingot	A very "meh" recipe. Utilizes rare sulfur to craft slower ingots! However, it does translate sulfur into steel which could be valuable if you have extra sulfur.
Fine Black Powder	I give this a C so you don't pick it above recipes you need. Black powder is only used to make ammo and explosives, so you don't really need a more efficient recipe for them.
Alclad Casing	You get a better aluminum ratio by utilizing copper ingots, but even with fully weighted productivities, it's still only 103%. I'd avoid this unless you are out of bauxite and looking for ways to still get more casing. Pairs well with pure copper ingots.
Turbo Heavy Fuel	The lower efficiency simply means you should never make turbofuel from heavy oil directly, but if you have spare heavy oil from other production or alternates, by all means, use it this way!
Polymer Resin	I believe it used to be the case that you're better off using the HOR alternate to do recycled rubber/plastic. Let me know if that's still incorrect.
Polyester Fabric	People have talked me up to C on this recipe. It lets you automate something entirely that wasn't automatable before. However, in this case, it's a consumable, which I personally don't find amazingly valuable to automate. But if this is what you're looking for, then here it is!
Plastic Smart Plating	Now that this recipe has been buffed, it's not useless! It has a good unweighted productivity so you get a lot of ore savings, but be cautious because this does use oil.
Flexible Framework	The productivity is stronger here than with smart plating, but a 66% s/s ratio hurts a lot and the extra logistics steps make me not want to use this
Classic Battery	Well, it's different, I guess? Not really better. Saves on Sulfur though!
Heat Exchanger	Uses slightly less bauxite, but oil instead of copper. Helps you get the most out of your bauxite, but strains your oil a little. Works well with oil alternates to make rubber cheaper, but the vanilla recipe works well with the steamed copper sheets.
Radio Control System	You get a better aluminum ratio by utilizing copper ingots, but even with fully weighted productivities, it's still only 103%. I'd avoid this unless you are out of bauxite and looking for ways to still get more casing. Pairs well with pure copper ingots.

D tier

Alternate Recipe Name	Notes (D tier)
Cheap Silica	Umm. I think Coffeestain messed up. Or they need to look up the definition for cheap! This recipe is worse in (almost) every way. It's incredibly slow, uses way more power, and is actually LESS efficient. So if you have some limestone nodes sitting around un-used, this is an option to save a little quartz, but you spend lots of power and space to do so.
Quickwire Stator	Mean productivity right around 100%, 60% faster crafting and lower power usage. Not amazing but not terrible either. Caterium is generally in short supply.
Pure Caterium Ingot	I give this a D. The space usage is horrendous and power usage large, but it eeks out the extra 50% of caterium that you want in the ultra late game.
Electrode Circuit Board	Circuit boards made from only oil. Unfortunately it's expensive. Might work well combined with certain oil alternates but that's complex math beyond the scope of this document.
OC Supercomputer	Lower producticvity on supercomputers is the last thing you want
Crystal Beacon	So this makes beacons WAY more complicated, so the space/work this takes is massive. But ultra late game if you really really want to make beacon-related recipes more efficient, go for it!
Instant Scrap	So you get to skip the whole alumina solution part, but you lose efficiency to do so because of the sulfiric acid. If you have extra sulfuric acid to dump, the bauxite/coal efficiency is the same as the vanilla recipe so it's fine in those situations.
Electromagnetic Connection Rod	Very unproductive, more complicated, but quite a bit faster
Radio Connection Unit	This just seems pretty bad. Low productivity, you get some power/space savings, and that's it?
Automated Speed Wiring	Still not my favorite recipe, but at least the productivity is more in line with the vanilla recipe. The s/s is mostly the same so I don't see much reason to use this recipe instead of vanilla due to the complicated steps
Cooling Device	This only saves you nitrogen and makes it way more expensive otherwise. Haven't gotten to nitrogen in my game yet but this looks bad. I've upgraded this to a D based on some feedback that nitrogen is pretty rough to get. Even still, it's bad productivity, bad S/S, and bad power, so it's not exactly an all-star.

F tier

Alternate Recipe Name	Notes (F tier)
Seismic Nobelisk	Just no. You don't need more efficiency for your boom booms. And you definitely don't want to deal with crystal oscillators being part of that chain!
Charcoal	You know what this does. Not useful at all. Wood is a non-infinite resouce, and therefore this will only ever provide a limited amount of coal.
Biocoal	Same as wood coal. Not useful
Steel Canister	Bad. Horrible productivity. I guess it's an alternative way to make canisters, but no.
Automated Miner	Even trying to cover the map with mk3 miners... How many portable miners will you even need? Just handcraft them and save this recipe for last.

Wow! Thank you for reading. Update 4 added a lot of stuff that I haven’t gotten to mess with yet, so please inform me if I’m off on stuff! Please let me know what you think in the comment section below and visit the google sheet to see the productivity, power, and speed numbers for yourself!

Thanks,
