The researchers studied how mixing organic garbage, reed, and cow manure in different ratios affects biogas production. They found that a mix of 1 part reed, 0.5 parts organic garbage, and 1.5 parts cow manure produced the most biogas. This combination had the best gas production efficiency, with a fermentation period of 37 days, reaching a maximum daily gas production of 3.2 liters per day. The amount of gas produced per unit of total solids was 361.88 mL/g, and per unit of volatile solids was 411.22 mL/g.
