Anaerobic digestion of pulp and paper mill wastewater

2014-11-15  Anaerobic digestion of pulp and paper mill waste at full-scale is currently confined to the treatment of a few selected types of effluent, and the resulting biogas is commonly burned to produce steam and electricity. Full-scale digesters for mill-derived sludges (biosolids) are almost non-existent.
