The current investigation concentrated on the production of biogas from Napier grass. The utilization of non-competitive biomass sources for biogas generation via anaerobic digestion is designed for long-term management in biogas production via anaerobic digestion. This study investigates the Napier grass-based biogas production application, which might be used to produce more cost-effective and sustainable biogas. The laboratory-based biogas plant and a biogas plant in operation demonstrated that the laboratory test results were practical and transferrable to practice. The effect of feedstock screening on the biogas yield of Napier grass and cattle slurry was studied in mesophilic CSTR technology digester. Furthermore, the maximum methane level was between 59 percent and 64 percent. Its organic nature makes it an excellent feedstock to produce biogas. Fresh grass was taken after 5 and 6 weeks of plantation, ground in 0.5 to 1 mm diameter size, and fermented in mesophilic CSTR reactors with solid concentrations ranging from 9 percent to 13 percent. At the optimum conditions, biogas yield was 136.4 mL – 142.20 mL CH4/g VS. The chemical composition of Napier grass (of all three samples) is shown in its approximate and ultimate forms. For a better understanding, grass collection and silage preparation are also displayed. The test was conducted in Ahmedabad, where the Arka BRENStech - Labio was installed (laboratory Biogas Digester) Napier grass (Pennisetum purpureum) was employed as a mono-substrate in all these tests.
