I work at an meat processing plant and take care of and compost the rumen innards from cattle (basically half digested grass) and pig hair.
We have multiple tonne to process every day.
Up until a few weeks ago, the mix was going straight out to worm farms, but due to increased waste production from increased factory production, the worms weren’t keepin up, even though we had 1000s of worm farms, which is when we thought about hot composting to speed up the process.
I posted on this sub reddit a month ago asking if anyone had any links to scientific research about hot composting, and through some helpful links, I started my researching journey.
The main factors I found to be integral in a great hot compost were,
Carbon to nitrogen ratio
Moisture %
Aeration.
We bought a supply of Barley straw, and saw dust, and also used all the cardboard from the factory.
Once we made thr piles, it didn’t take very long to get hot, by 24 hours they were steaming.
We have a pile that’s over 2 weeks old now, and it’s still too hot to touch.
We turn the piles twice a week.
Hope you find this interesting, and feel free to ama. 😊
