G'day all!<br>
<br>
I've come across an interesting case study using cow manure and vermiculture. Unfortunately, this list won't let the link be included. Just google Large-Scale Vermicomposting of Dairy Manure (I hope this is the link Wayne meant - <a href="http://www.extension.org/sites/default/files/w/1/1a/07decPPherlihy.pdf" target="_blank">http://www.extension.org/<u></u>sites/default/files/w/1/1a/<u></u>07decPPherlihy.pdf</a>)<br>
<br>
Apart from the obvious digesting of what they pump off to the aeration lagoon, I was wondering is if is possible to replace their Pre‐Vermicomposting Conditioning (composting active aeration) stage with (probably high solids) anaerobic digestion? The goal would be to get some energy/biogas out of this input material/feedstock but leave enough food for the worms to eat. That we get biogas, biofertilizer and worms (as a high protein feed supplement) and well as serious odour elimination. If it is possible that what sort of retention time are we looking at optimally?<br>
