Year-on-year increase in biogas capacity is likely to drive the demand for anaerobic digestors (AD). AD remains one of the prominent routes for biogas recovery.
The five players in the global anaerobic digestion market are Siemens AG, GE, Veolia, 2G Energy AG, and Voith GmbH & Co. KGaAa.
Europe dominated the market in 2025 in terms of both value and volume. In terms of CAGR, North America and Asia Pacific remains the most lucrative markets for anaerobic digestion.
In terms of type, the flow plug digester segment dominated the global anaerobic digestion market in 2025.
The global renewable electricity capacity additions were 11% lower in the first half of 2020 than in the same period in 2019 due to the COVID-19 pandemic. This has impacted the investments into planned AD facilities as well.
