= 15 m3 Manure / Cattle p.a. (in Europe 20 m³)
= COD load 50 -100 000 ppm = 450 m3 Biogas p.a. = approx. 900 kWhel p.a.
= 70% COD Reduction
Biogas From one Cattel/Pig…
One pig produces energy equivalent to 23 l/year of diesel oil.
Substrate Dry Matter m³/t Biogas CH4 (%)
Cattle Manure 5-10 % 15-30 57
Pig Manure 6 % 20 59
Hen Manure 20-60% 70 - 200 60
Mais Silage 34% 210 53
!! Fast degration (aerobic) => Fresh Collection !!
