The best thing you can do with prisoners is harvest their hemogen. Unfortunately, it doesn't have many uses in the game. With this mod you can recycle the excess into chemfuel.
There's already a similar mod, but it allows for processing into neutroamine. So why chemical fuel?
Well, for some reason, Tynan Sylvester doesn't allow the player to produce certain components, only purchase them. These components include Neutroamine. This mod can be considered closer to the vanilla state of the game, since it allows you to do is remove excess hemogen from the stockpile, which cannot be processed or sold. In the end, hemogen is also organic
What about balance?
The mod uses the same ratios as the game itself: a full stack of hemogen produces half stack of chemfuel. In other words, two blood packs yield 7 units of chemfuel. That's why pawns of Rimworld bred Boomalopes! In addition, hemogen refining is a little slower than organics refining, just as vanilla organics refining is a little slower than wood refining
How can I convert hemogen into chemfuel?
You will need to research 2 technologies - Biofuel Refining and Deathrest and then recipes will appear into Biofuel refinery
