OKD - How about composting and then having the worms work it to refine it? Seems to be an excellent method.
A recipe for a balanced nutrient cycling ACT which many growers claim to have great success with is;
[vermi]compost – 2.38%
unsulphured pure black strap molasses - 0.50% [but you can use a maximum 0.75%]
fish hydrolysate (high quality) - 0.063%
Do not use chemically deodorized liquid fish!
kelp meal - 0.25% max. [Less is more!]
NOTE: This is a maximum amount of kelp and you can experiment using less. This is using regular grade kelp meal for livestock. If you have soluble kelp, I recommend using smaller amounts. As noted earlier kelp meal can initially delay bacterial multiplication and fungal growth in ACT.
soft rock phosphate granules/powder - 0.063% Consider this optional. In the past 2 years I’ve become more aware of the possibility of polonium 210 and lead content in soft rock phosphate which is radioactive. This varies depending on how it was mined and where. If you wish to use this in ACT check all available data. Look for heavy metal testing
We grind up the granules into a powder with a coffee grinder
The brew time should average around 36 hours and no longer than 48 hours. If you have a microscope then stop when the microbes desired are observed. Otherwise smell for the foodstocks being used up, possible rank odor (indicating anaerobes) and a positive earthy or mushroom-like aroma.
smelled pretty rank."
