Mr. Brendan Gildea:

In response to the question on the input system, in my system we have a mixing tank where we pump in our fresh slurry. We put 15 tonnes of fresh slurry in per day, add one tonne of straw bed and then mix it all up. It is added hourly throughout the day. As it comes out, it is a tip-over or floor system. We separate our digestate into liquid and solid. We then have a highly enriched liquid slurry. After the digestion process, the nitrogen availability has probably doubled.
