Main Factors Affecting the Production of Biogas during Anaerobic Digestion Process

Abstrak

Fossils like coal, natural gas, and oil have been extensively used due to the twentieth century’s worldwide economic growth. These fossils were used as fuels and pharmaceutical raw materials. As a byproduct of combustion, the widespread use of fossil fuels has resulted in massive carbon dioxide releases. The so-called “greenhouse effect” can be attributed to carbon dioxide’s high infrared absorption rate. Biomass-based sustainable energy sources have recently gained prominence due to a growing movement to at least partly substitute oil usage and, by extension, reduce greenhouse gas emissions from the atmosphere. The manufacturing of chemicals could switch to biofuels as a basic substance. One of these renewables is biogas, produced through the anaerobic digestion of various forms of organic waste into natural gas. Temperature, pH, hydraulic retention time (HRT), and other elements are just a few of the key variables studied in the present study that influence biogas output. A portable closed batch process was utilized. Biogas technology produces energy from biological matter or biological waste (substrate) that also benefits human health and the ecosystem. The water displacement technique was used to measure the biogas generated in laboratory-scale trials to determine the biogas yield. Cow dung, potatoes, onions, lettuce, carrots, and cabbage are some substrates used. For two weeks, mesophilic temperatures supported the biogas generation process.
