“…Heat demand includes the heat necessary for the influent to reach the temperature of the reactor and heat losses. Heat losses were estimated assuming that the digester temperature underwent a decrease of 0.56 C each day [42]. Heating requirements to increase the temperature of the influent to the digestion process were calculated assuming an average entrance temperature of 15 C. CW was assumed equal to water for density (1 kg L À1 ) and specific heat (4.18 kJ kg À1 C À1 ).…”

“…Many studies have been conducted concerning the environmental sustainability and performance of biogas production systems (Edelmann et al, 2005;Appels et al, 2011;Tricase and Lombardi, 2012;Pertl et al, 2010;Dressler et al, 2012;Pöschl et al, 2012) as well as biogas conversion into electricity (Hartmann, 2006;Benetto et al, 2010). In particular, special attention has been paid on GHG emissions (Clemens et al, 2006;Rehl and Muller, 2013;Dressler et al, 2012) and energy balance (Börjesson and Berglund, 2007;Benetto et al, 2010;Kimming et al, 2011;Dressler et al, 2012) related to these bioenergy systems.…”
