[Digestion] Well balanced co-feedstocks and fertiliser for coffee grounds

[Wayne Zschech]

G'day all!

I'd like advice as to what could be used as co-feedstock(s) together with
used coffee grounds. Also the proportions of the daily inputs. We have a
10m3 reactor that will be operating at 35oC. The coffee grounds will be
available all year round.
We'll have plenty of grass and weeds during the summer. We are expecting
cabbage (and maybe onion) waste in the winter.
The is pig manure available but do I need much of it? Paper waste is also a
possibility and I could organise some canteen/kitchen waste.  The is a
short season with sugar beet waste is available.

We are also wanting to supply local vegetable growers with the liquid
fertiliser.  So, what do we need a minimum as a feedstock to produce a
quality (or reasonable quality) fertiliser?  Potatoes, carrots, onions,
tomatoes, cucumbers and beetroots are the main cultures grow.

Thank you. As always, your input is appreciated.
Blessings,
Wayne
