Laboratory anaerobic digesters were fed dairy and swine manure at the rates of 0.1 and 0.2 kg volatile solids (VS)/ m3-day over the temperature range of 10–23°C. The digesters were operated successfully with little indication of instability. Methane (CH4) yield, (B, m3 CH4/kg VS added) was determined to typically decrease linearly as temperature (T, °C) was decreased: Dairy at 0.1 kg VS/m3-day B=0.1153+0.0053TDairy at 0.2 kg VS/m3-day B=0.0820+0.0063TSwine at 0.1 kg VS/m3-day B=0.2011+0.0053TSwine at 0.2 kg VS/m3-day B=0.3177+0.0044T Some increased performance was suggested for the lower loading rates compared with higher loading rates.
