  In this study we developed and tested a sustainable system that produces high-yield outputs of biomethane, biofertilizer and biodiesel. These were achieved by blending of poultry manure (PM), paper pulp and algae waste sludge in co-digestion producing biomethane, digestate fi ltrated to get semi-solid and aqueous, the former as biofertilizer and latter was used in algal cultivation to enhance algal biomass for biodiesel production. The varied blending of the substrates resulted in carbon/nitrogen ratios (C/N) of 26, 30, 31, 34 and 37 which were assessed for biomethane. C/N 26 resulted in 1045 ml/L/d (74% biomethane content) which was highest yield comparing to other C/N, C/N 30 achieved in similar (1010 ml/L/d) making the C/N range for optimum biomethane for these substrates to range between C/N 26 to 30. In comparison, C/N 31 to 37 achieved lower biomethane yields indicating. Pretrea.. View More»
