Biogas production by anaerobic treatment of biowaste: a theoretical and experimental approach

The transition to waste-to-energy conversion using anaerobic digestion (AD) technique is of great importance as it could be the key to support bio-based economy and it offers an economical alternative for bioenergy production. Here, we aimed to understand the degradation of different types of organic waste into biogas and evaluate the impact in the conversion efficiency. Inoculum-to-substrate ratio was an essential parameter for optimal degradation of organic waste. Additionally, co-digestion of biowaste with cow manure improved the performance of the anaerobic digestion. Similarly, ternary digestion of organic waste could have positive impact on biowaste treatment. Finally, subtle issues were spotted and highlighted amid the application of anaerobic digestion to detect fundamental changes in the bioenergy landscape and underpin the drive for global sustainability; lastly, an outlook was suggested for how the field may progress in the future.
