This work focused on the valorization of piggery industry slurry to bio energy and bio fertilizers. A sample of piggery slurry wastewater was treated using a bio catalyst, Actizyme at 0.050 g/L loading, resulting in reduction of the biological oxygen demand (BOD) by 97%, the total dissolved solids (TDS) by 89% and the total suspended solids (TSS) by 98%. The solid material from the slurry was anaerobically digested to produce biogas with 73.4% methane composition over a period of 30 days and temperature of 37 ◦C at a commercial rate of 494 kg/day. The techno economic assessment for the piggery slurry valorization indicated a return on investment of 26% and payback period of 4 years and a capital investment of USD 820 000.
