Abstract

This study investigates the effect on methane production from waste paper when co-digested with macroalgal biomass as a source of nitrogen. Both feedstocks were previously mechanically pretreated in order to reduce their particle size. Methane potential assays were carried out at laboratory scale in batch mode for 28 days. The highest methane yield (386 ml/g of volatile solids (VS)) was achieved at a F/I ratio of 0.2 and a WP/MA ratio of 50:50. The methane yield at a ratio WP/MA of 50:50, which represents an increase of 30% compare with mono-digestion of algae and 22% with mono-digestion of waste paper. Synergistic effect was found for the WP/MA ratio of 50:50 and all F/I ratios. It was concluded that methane production from waste paper improves significantly when co-digested with macroalgae biomass. The methane yields from co-digestion were also found higher that from macroalgae mono-digestion
