Strengthen “the sustainable farm” concept via efficacious conversion of farm wastes into methane

With escalating global demand for renewable energy, exploitation of farm wastes (i.e., agriculture straw (ASWs), livestock wastewater (LW) and sewage sludge (SS)) has been considered to attain maximum methane yield (MY) via anaerobic digestion (AD). Results pointed that mixture SS LW as anaerobes’ source with 20 g ASWs/300 mL working volume achieved MY volatile solid (VS) removal efficiency 0.44 (±0.05) L/gVS 51.4 (±4.1)%, respectively. This was mainly because emerging heavy duty bacterial species Syntrophorhabdaceae Synergistaceae) archaeal community (i.e, Methanosarcina Methanoculleus) after 70 days incubation. acquired along boosting enzymatic activity, especially xylanase, cellulase protease up 71.5(±7.9), 179.3(±14.3) 207.2(±16.2) U/100 mL, Furthermore, the digestate contained high concentrations NH4+ (960.1±(76.8) mg/L), phosphorus (126.3±(10.1) mg/L) trace metals, making it a good candidate organic fertilizer.
