Anaerobic Digestion
Transforming Waste into Renewable Energy
Anaerobic Digestion (AD) is a time-tested technology that converts organic waste into valuable resources. By breaking down materials like food waste and agricultural residues in an oxygen-free environment, AD produces biogas—a renewable fuel—and nutrient-rich digestate, which can be used as a fertiliser.
How It Works
In an anaerobic digester, microorganisms break down organic matter through four stages:
-
Hydrolysis: Complex materials are broken down.
-
Acidogenesis: Conversion to volatile fatty acids.
-
Acetogenesis: Formation of acetic acid, CO2, and hydrogen.
-
Methanogenesis: Production of biogas.
​
Biogas can generate heat, electricity, or be refined into
biomethane and digestate is a valuable agricultural fertiliser.

Key Benefits
-
Waste Reduction: Converts waste into renewable energy and fertiliser.
-
Energy Production: Provides a sustainable energy source.
-
Environmental Impact: Lowers carbon emissions and reduces landfill use.
-
Economic Returns: Offers financial benefits through energy sales and grants.
​
Grants Available in Ireland
To support AD projects, the Republic of Ireland offers several incentives:
-
Support Scheme for Renewable Heat (SSRH)
-
Accelerated Capital Allowance (ACA)
-
Targeted Agricultural Modernisation Scheme (TAMS)
These grants help offset initial costs, making AD projects more accessible.

Is AD Right for You?
Consider the availability of feedstock, market for digestate, site suitability, and financial capacity before investing in AD. With the right conditions, AD can be a highly rewarding venture.
