Anaerobic Digestion

Anaerobic Digestion

Turning Waste into Energy

In 2015, in partnership with Iona Capital, we established a state-of-the-art anaerobic digestion (AD) plant at Charlesfield. This facility plays a crucial role in Scotland’s transition to renewable energy, converting organic waste into methane gas, which is injected directly into the local gas grid.

How It Works:

  • Organic materials such as food waste, agricultural residues, and biodegradable materials are processed in oxygen-free conditions.
  • This process generates biogas, primarily composed of methane.
  • The gas is cleaned, upgraded, and injected into the national grid, providing a sustainable alternative to fossil fuels.
  • The remaining digestate is a nutrient-rich by-product that can be used as a natural fertiliser, supporting regenerative farming practices.

Contributing to National Energy Goals

The Charlesfield AD plant directly supports Scotland’s renewable energy targets, helping to reduce reliance on fossil fuels and lower carbon emissions. Our facility provides:

  • A sustainable energy source that directly supplies homes and businesses.
  • A low-carbon alternative to traditional gas, reducing overall emissions.
  • A circular economy solution, ensuring waste is repurposed effectively.

Exploring Future Renewable Energy Initiatives

Our commitment to renewable energy doesn’t stop at anaerobic digestion. We are continually exploring ways to enhance our energy efficiency and sustainability further, including:

Battery Storage Solutions – Increasing energy efficiency by storing surplus power for future use.

Solar Energy – Harnessing Scotland’s daylight hours to generate clean electricity.
