Anaerobic Digestion Market to Reach $26.5 Billion by 2035

The global market for anaerobic digestion is expected to significantly expand in the coming decade, according to a new report by Strategic Revenue Insights Inc. (SRI). The market was valued at $12.50 billion in 2025 and is projected to reach $26.49 billion by 2035, growing at a compound annual growth rate (CAGR) of 7.80%.

The report analyzes market dynamics across feedstocks, technologies, applications, and end-users from 2026 to 2035. Wet anaerobic digestion is identified as the most widely adopted technology. While electricity generation represents the largest application segment, biomethane injection is emerging as the fastest-growing application. Municipalities are the predominant end-user segment.

Key factors driving market growth include the increasing demand for renewable energy and sustainable waste management solutions, supportive government policies aimed at reducing carbon emissions, rising costs associated with traditional waste disposal methods, and a growing interest in biomethane as a viable alternative to fossil fuels. Geographically, Europe currently holds the largest market share, with the Asia Pacific region anticipated to experience the most rapid growth.

Despite the positive outlook, the market faces challenges such as regulatory hurdles, competition from alternative waste management technologies and renewable energy sources like solar and wind, and fluctuations in feedstock availability and quality. Key industry players mentioned in the report include Veolia Environnement S.A., Xylem Inc., and EnviTec Biogas AG.
