Mekanism Rotten Flesh Crusher Conversion
by derexXD
Mekanism Rotten Flesh Crusher Conversion restores the rotten flesh to biofuel crushing recipe that Mekanism dropped, so zombie drops can feed the crusher again.
What it does
Mekanism once let players crush rotten flesh into biofuel, and later versions removed that path. This addon adds the recipe back, turning one rotten flesh into two units of biofuel in the crusher. Biofuel from the crusher is the route the author describes for fueling generators, in place of the composter-based generation that Minecraft uses.
The addon suits worlds with zombie farms, where rotten flesh piles up, and it pairs with contraptions built in other modpacks. It runs on the server only, so players join without installing anything. Files are published for Forge, for 1.16.5 and 1.19.2, with 1.0.0.0 for 1.19.2 as the latest file. The code is under the MIT License and is open source, and the author also credits the Mekanism team and the modpacks that use the addon.
Key features
Rotten flesh to biofuel
Crushing one rotten flesh yields two biofuel, restoring the conversion that Mekanism removed.
Zombie farm supply
Rotten flesh from zombie farms becomes a steady source of biofuel for crusher-based setups.
Crusher recipe addition
The conversion is added as a crusher recipe, so it works in the same machine players already use.
Pairs with contraptions
Biofuel from farms can feed machines in combined builds that players assemble around zombie farms.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Zombie farm powered generators
Players with a zombie farm can route its rotten flesh through the crusher to produce biofuel for generators.
Modpack integration
Modpack builders who want biofuel from rotten flesh can add the addon without changing Mekanism itself.
Who it’s for: Players who run zombie farms with Mekanism, and server owners who want rotten flesh to produce biofuel again.
How it compares
Smelted Flesh is a server-side only Forge mod under the MIT License, built for 1.20.1 and so does not cover 1.19.2. Rotten Flesh into Leather is published for Fabric, Forge and NeoForge under the MIT License, and targets 1.20 – 26.1.2, a range that does not overlap this addon's 1.16.5 and 1.19.2 files. Both change rotten flesh, but they convert it to different outputs rather than to biofuel.

What the author says
Using the Crusher to Crush rotten flesh into biofuel used to be a mekanism feature but was removed as they wanted the biofuel generation to be based on the composter in Minecraft. This addon simply just adds that feature back, allowing you to crush 1 rotten flesh into 2 biofuel. You can make good use of zombie farms…
