Testing it right now, so far ive created biochaff within 28 seconds with a LV macerator, costed 891 eu for 1 biochaf, i then made it into 1 bucket of biomass from 1 bucket of water and 1 chaff, also within 28 seconds and 768 eu.
Then i built the distillation tower, setup looks like this

From left to right, LV macerator, distillation tower. I ran it with 8 potatoes which produces 1 bio chaff, which turned into 1 bucket of biomass. The bucket of biomass was run without issues in the distillation tower consuming
313653 eu or 78408,75 eu/250 mb to produce 32000 mb of biogas, 500 ml of water, 4 fertilizer and strangely enough 6 small piles of wood pulp. Didn't time it but seemed to be around 28 seconds

Then running the biogas in a LV diesel generator i filled 9 lithium batteries to 89504 or 805536 total eu (this took ages, should have used HV) This means the total heating value of the gas should be 805536/0,9=895040 eu

Net gain of the setup is 895040-313653-891-768=579723 eu/28 sec or 1035 eu/tick worth of fuel excluding cable losses
The easiest way to set up this would be a turbo gas turbine for the distillation tower (this would consume 78408,75/0,7=112012,5 EU) and a basic gas turbine to run the fluid/solid canning machine and LV macerator. Once you get it started on energy it would run self sufficient after you have processed your first 8 potatoes with a net energy output of 895040-4*112012,5-891/0,9-768/0,9=445117 eu/28 seconds or 795 eu/tick worth of fuel excluding cable losses.
Broken is the word i would use
