Two-Stage Anaerobic Digestion for Green Energy Production: A Review

Processes, Journal Year: 2025, Volume and Issue: 13(2), P. 294 - 294

Anaerobic digestion (AD) is a biotechnological process in which the microorganisms degrade complex organic matter to simpler components under anaerobic conditions produce biogas and fertilizer. This has many environmental benefits, such as green energy production, waste treatment, protection, greenhouse gas emissions reduction. It long been known that two main species (acidogenic bacteria methanogenic archaea) community of AD differ aspects, optimal for their growth development are different. Therefore, if performed single bioreactor (single-phase process), selected taking into account slow-growing methanogens at expense fast-growing acidogens, affecting efficiency whole process. led two-stage (TSAD) recent years, where processes divided cascade separate bioreactors (BRs). division consecutive BRs leads significantly higher yields two-phase system (H2 + CH4) compared traditional single-stage CH4 production review presents state art, advantages disadvantages, some perspectives (based on more than 210 references from 2002 2024 our own studies), including all aspects TSAD—different parameters’ influences, types bioreactors, microbiology, mathematical modeling, automatic control, energetical considerations TSAD processes.
