Use of agriculturally-produced substrates/energy crops<br />
In agricultural biogas plants, liquid manure and silage are most often utilized as feedstock.<br />
From the digestate, fertilizer is produced as a by-product. These fertilizers are<br />
chemically much less aggressive than raw liquid manure, nitrogen availability is better,<br />
and the odor is less intensive. Digestate from wet fermentation („biogas manure") is a<br />
liquid manure-like substance. For the pure use of energy crops, a multi-stage plant<br />
would be required for optimal feedstock utilization – in some cases through the use<br />
of dry fermentation for the optimal combination of logistical conditions.<br />
