This automation uses Oritech's machines to produce biosteel from biofuel (I used XyCraft's Extractor to produce moss) and iron (I used easyvillager's iron farms to produce iron).
The moss goes into a Mekanism's Crushing Factory to be turned into biofuel and then a block of biofuel, which is used in the centrifuge with water to make raw biopolymer, which is sent to the foundry with iron to make the biosteel.
This farm isn't the best or most effective one, but it's simple, you can make it early on, it keeps producing it indefinitely, and it's fun 😀.
