Why Do Agricultural Residues Dominate the Anaerobic Digestion Market in 2025?

The agricultural residues segment is expected to hold 31.5% share of the global anaerobic digestion market in 2025, due to the abundant availability and sustainable nature of these feedstocks. Agricultural residues include plant waste products of harvesting and processing of crops in the form of crop stalks, husks, straw, and leaves. These residues are not fully utilized in most areas of the world or they are burnt, which also pollute the environment. Nevertheless, their incorporation into the anaerobic digestion systems is a greener way of transforming waste in bio-energy and decreasing the emission of greenhouse gasses.

For example, Verbio SE commissioned a large BioCNG/biomethane biorefinery in Punjab that uses rice straw (an agricultural residue) as the primary raw material, explicitly positioned to reduce stubble burning by creating a commercial outlet for straw collection and conversion via anaerobic digestion-based processing.

Electricity Generation Dominates the Anaerobic Digestion Market

Electricity generation segment is projected to hold 29.7% share of the global anaerobic digestion market in 2025, mainly due to the pressing need in the world to cease reliance on non-renewable sources of energy. Biogas that are generated due to anaerobic digestion contains a lot of methane that can be directly transformed into electricity through gas engines or turbines. This dominance of the application indicates the increase in the need to minimize the reliance on fossil fuels, to increase stability of grids, and to achieve renewable energy goals imposed by governments around the globe.

One of the reasons that have driven electricity generation by anaerobic digestion is the flexibility that biogas holds as a fuel. Not all the renewable sources are intermittent e.g. solar and wind, but biogas is a storage and on-demand facility hence making it a reliable base-load source of power. This renders it especially appealing to decentralized energy systems and areas remote to grid connectivity or unreliable.

The market growth and the use of technology are facilitated by government incentives like the Renewable Heat Incentive and the Contracts for Difference scheme.

The availability of bio-gas operators such as Celtique Energie and Future Biogas places the U.K. at the center of the large-scale production of biogas using agricultural residues and food waste. The gradual incorporation of biomethane injection into the national grid is a strategic development in terms of sustainable energy source, which is justified by effective legislation and people becoming more and more accepting of bioenergy solutions.

Feedstock Economics

Feedstock economics covers variable costs for materials like agricultural waste (manure, crop residues), municipal solid waste, and industrial organics, which dominate AD inputs due to their abundance and low opportunity cost. Regional benchmarks account for factors such as transport logistics, seasonal availability, and preprocessing needs, with higher yields in warmer climates (e.g., Midwest U.S. swine manure systems yielding more methane per head due to temperature-driven emissions baselines). Data typically benchmarks costs at USD 20-50/ton globally, influencing overall project capex/opex.

Carbon Credit Models

These models quantify verifiable emission reductions (e.g., CH4 avoidance from manure management, CO2e sequestration via CCS add-ons), generating credits sellable in voluntary markets or compliance schemes like LCFS/RFS. U.S. examples project USD 68-200/ton incentives from stacking LCFS with 45Q tax credits (USD 85/ton for capture), boosting AD ROI by 20-50%. Global protocols emphasize additionality and baselines tied to regional manure systems.
