Abstract
Co-digestion of various wastes and biomass feedstock has been shown to improve the digestibility of the materials and biogas yield. In this study,the co-digestion of water hyacinth and fish waste was studied at different mixing proportions. The anaerobic digestion was carried out in batch digester reactors sized 500 ml and were charged to 10 % of total vol-ume. Co-digestion was conducted for a retention period of 21days in mesophilic temperature ranging 25.3 °C to 33.4 °C. The research revealed that the highest biogas production was observed from the combination of FW:WH, at 1:2 ratio. The maximum biogas recorded was 0.56 literswith compo-sition of 73.3 % CH4. Furthermore, the water hyacinth also recorded0.46 literswith the composition of 70 % CH4which suggesteconomical feasibility. The overall results showed that blending water hyacinth with fish waste had significant improvement on the biogas yield.
