摘要: Abstract The impact of anaerobic digestion (AD) technology on mitigating greenhouse gas (GHG) emissions from manure management typical dairy, sow and pig farms in Finland was compared. Firstly, the total annual GHG were calculated using IPCC guidelines for a similar slurry type system. Secondly, laboratory-scale experiments conducted to estimate methane (CH4) potentials process parameters semi-continuous manures. Finally, obtained experimental data used evaluate potential renewable energy production subsequently, possible that could be avoided through adoption AD studied farms. Results showed enteric fermentation (CH4 N2O) accounted 231.3, 32.3 18.3 Mg CO2 eq. yr−1 farms, respectively. With existing farm yields, an estimated 115.2, 36.3 79.5 MWh heat yr−1 62.8, 21.8 47.7 MWh electricity yr−1 could generated CHP plant these offset dairy cow, 177, 87.7 125.6 Mg eq. yr−1, mainly replaced fossil fuel consumption followed by reduced due fertilizer use production, management.
