Can someone explain to me the use of the recycled rubber/plastic recipes?

[Dr.Acula]

I don't really understand the purpose of these two recipes. Sure I can produce larger quantities of plastic/rubber with one refinery but I still need more refineries for the fuel and rubber/plastic to produce the recycled equivalent afterwards.

Thinking about it it looks like I'm getting more rubber/plastic per unit crude oil but at the same time it makes the production process more convoluted. In addition when I produce plastic/rubber from crude oil I always have heavy oil residue which I can then use for petroleum coke and/or (turbo) fuel.

Am I missing something here?

[kLuns]

No you didn't miss anything. Your own recipe analysis answers the question you asked above.
Numbers wise: 4,5 times the regular amount of plastic/ rubber out the same amount of oil if you squeeze it with other alternates.

[Kage Goomba]

It's just an option.

Allows you to make the most rubber/plastic in one shot - but the cost is fuel ultimately.

All Alternate Recipes have a Pro and a Con.

It's entirely up to you on when/how you use them.

I'm sure someone has an idea or two for its use.

There are no "bad" or "good" alternate recipes - its just a matter of situational use.

Do the math of producing the plastic and rubber directly from a pipe of crude. then do the math on how much you will get by turning the crude into heavy oil residue, then into diluted fuel.
Take the resin byproduct from the heavy oil residue, and turn it into rubber, then use the fuel to keep doubling it to plastic, double to rubber again double to plastic etc.
The final yield is substantially more plastic and rubber.

Iirc i'm turning 3x600 pipes and 1x450 pipe of crude into 2400 rubber/min and 4000 plastic/min give or take. dont remember exakt numbers.

[Broseidon]

with the recycled recipes (need both) and a few other alternate recipies: Heavy Oil residue and diluted fuel, you can produce 900 rubber/min or 900 plastic/min from a single 300 crude oil/min normal node, without any byproducts.

ofc the build gets larger and more complicated, but isn't that the point of min/maxing?

It's more complex but the HOR > diluted fuel > recycled recipes chain is basically voodoo.

I keep forgetting the power of Diluted Fuel - so OP.

300 Crude?

300 Crude?

yes 300 crude -> 400 HOR -> 800 fuel (diluted)
(the 200polymer from the HOR recipe gets turned into 100 rubber to kickstart the recycled plastic)
the fuel is then split between the recycled rubber / plastic, the ratio depends on what your end product is, if you want rubber or plastic.

but it takes like 42 refineries to do.

Yes, it's a 1:3 ratio with recycled recipes, as opposed to 3:2 with the regular recipe.
As said above, it's 4,5 times more plastic/rubber per crude oil. The system is more convoluted but the net result wins all rounds
I grew so fond of it that I systematically pick rubber alt recipes for my production: rubber concrete, heavy flexible frames etc...

[Maehlice]

I misread the 900 Plastic OR 900 Rubber. 900 ppm combined total of Plastic and Rubber.

Nevermind me.

[Dr.Acula]

Well I haven't really required a massive rubber or plastic production (yet). My latest project was Heavy Modular Frames (30 per minute) in which I used 1020 Crude Oil with the following result:

600 Rubber (for HMF)
75 Plastic (for modular frames)

The Heavy Oil Residue was used for:
787.5 Petroleum Coke (for steel => Encased Steel Beams and Screws for the HMF)
300 Turbo Fuel => 10.000 MW of power production

The respective factory utilizing the crude Oil:

I will not rule out recycled plastic and rubber but so far I haven't really seen the value in it.

Circuit-type components use a lot of Plastic & Rubber. Beyond that, the "Coated/Insulated/Flexible" alternate recipes simplify logistics for me.

The electronics part is why I'm not ruling it out. Just saying that for the moment I think I used my Crude Oil pretty efficiently and for the HMF I'm already working with the coated iron plates and Heavy Flexible Frame.

In addition I used the Coke Steel Ingot to basically remove the coal requirement from the HMF altogether (but I use 300 coal and sulfur for the turbo fuel)

[wux]

You're unlikely to ever need it - almost everyone who plays will never come close to using all the oil available.

It's just an option. It's ridiculously efficient and has no byproducts, so a lot of players like it. If you go very large scale rocket fuel at some point later on you can basically get all your rubber/plastic as an aside, which is also nice.

There's nothing wrong with just using the regular recipes though, it just depends what you want to build.

[Dr.Acula]

Well usually I try to use recipes that create better more efficient alternatives - especially when it results in requiring less construction work. I do not have a high priority on making production lines any more convoluted than they already are and the recycled rubber/plastic part gives me a bit of a headache in planning (although the satisfactory calculator helps a lot)
