Ecological and economic evaluation of biogas from intercrops

Table 3 Substrate parameters

Parameters	Cattle manure	Corn silage	Intercrops	Grass silage
Dry mass content (%)	9	33	24	30
Substrate costs^a minimum (€/t DM)	5	65	50	50
Substrate costs^a maximum (€/t DM)	10	90	80	80
CH₄ output (m³/t DM)	200	340	300	300

In Table 3, the substrate parameters are described. The optimization is based on two different cost situations (maximum and minimum) for substrate supply. ^aAll costs decided by regional actors. t, tons; DM, dried mass.
