Abstract
The biogas potentials from 2 biosludges from the pulp- and paper industry and 10 possible co-digestion substrates have been evaluated. 6 combinations, each including two co-digestion substrates and one biosludge, were evaluated in lab scale biogas reactors. Stable biogas processes were obtained with all combinations and the rawgas potential was higher in the co-digestion processes then for the biosludges alone (0.31- 0.43 compared to 0.21- 0.22 NL/g VS) The investment costs for two production plants were calculated. For a plant using 7 ton biosludge TS/d (total solids per day), co-digested with evaporation condensate (3 m3/d) and fibre sludge (3 ton/d) and thereby producing 850 000 Nm3 CH{sub 4}/yr the investment cost was estimated to 43 MSEK excluding ground works. For a larger plant using 20 ton biosludge TS/d, co-digested with food waste (8 ton/d) and cereal residues (12 ton/d) and producing 2 500 000 Nm3 CH{sub 4}/yr, the investment cost was estimated to 51 MSEK excluding ground works
