Anaerobic Digesters Market Report 2026

The anaerobic digesters market size has grown strongly in recent years. It will grow from $10.77 billion in 2025 to $11.42 billion in 2026 at a compound annual growth rate (CAGR) of 6%. The growth in the historic period can be attributed to increasing industrial wastewater generation, rising organic waste disposal requirements, adoption of anaerobic treatment in food processing, expansion of paper and chemical industries, availability of proven digester technologies.

The anaerobic digesters market size is expected to see strong growth in the next few years. It will grow to $14.26 billion in 2030 at a compound annual growth rate (CAGR) of 5.7%. The growth in the forecast period can be attributed to increasing investments in renewable energy from waste, rising regulatory pressure on waste treatment, expansion of circular economy initiatives, growing focus on energy recovery efficiency, increasing adoption of smart digester control systems. Major trends in the forecast period include increasing deployment of high-rate anaerobic digesters, rising adoption of modular digester systems, growing integration of biogas recovery technologies, expansion of industrial waste treatment applications, enhanced focus on process optimization and monitoring.

The rise in biogas production is expected to drive the growth of the anaerobic digesters market in the coming years. Biogas production refers to the process of generating renewable gas from organic waste through anaerobic digestion. This increase in biogas output is fueled by the need for renewable energy, efforts to reduce dependence on fossil fuels, sustainable organic waste management, and the goal of lowering greenhouse gas emissions. Anaerobic digesters support biogas production by efficiently decomposing organic waste in an oxygen-free environment, resulting in biogas that can be used as a renewable energy source. For example, in June 2025, the European Biogas Association - a Belgium-based organization - reported that Europe’s installed biomethane production capacity in Q1 2025 rose from 6.42 bcm in 2024 to 7 bcm, representing a 9% increase over the previous year. Therefore, the growing production of biogas is contributing to the expansion of the anaerobic digesters market.

Companies in the anaerobic digester sector are focusing on innovative solutions, such as micro anaerobic digester systems, to meet the increasing demand for sustainable waste management. Micro anaerobic digester systems are compact, closed biological reactors designed to decompose organic waste, such as food scraps, agricultural residues, or sewage, in an oxygen-free environment. For instance, in February 2023, BioFactory, a UK-based provider of energy equipment and solutions, introduced the Micro AD Farm. This micro anaerobic digester system is specifically designed for smaller dairy farms with 100 to 500 cows. It enables farmers to convert cow slurry into renewable energy, helping to reduce energy costs and lower greenhouse gas emissions. The system’s modular and scalable design allows for easy expansion and quick installation, making it suitable for farms with limited resources. Additionally, it improves slurry quality, benefiting soil health and nutrient uptake in crops.

In December 2023, Ares Management, a US-based asset management firm, acquired Burnham RNG for an undisclosed amount. This acquisition aims to enhance Ares Management's renewable natural gas portfolio and support the development of waste-to-value projects, driven by the growing demand for sustainable waste management and renewable energy. Burnham RNG, a US-based developer of organic waste management and anaerobic digestion biogas assets, will contribute to this effort.
