Experimental study examines how fermentation temperature and C/N ratio affect biogas yield in livestock waste, indicating potential for industrial applications.
Key Points
Thermophilic fermentation increased biogas yield by 20-28%, enhancing methane concentration by 5-10%.
Poultry manure yielded the highest biogas output of 0.42 m3 per kg of organic dry matter and methane at 70%.
Experiment compared two temperature conditions—mesophilic and thermophilic—using various organic wastes.
Optimising the C/N ratio and co-fermentation further improved biogas production efficiency for industrial use.
