Anaerobic digestion (AD) isn’t a new technology. It’s actually been around since the 1800s. But, as concerns about the environment grow, so has the demand for ways to generate renewable energy and, as a result, investments in AD over the past few years have increased.

AD converts organic material such as food waste, slurries and crop residues into bio-gas; a methane-rich gas that can be used as a renewable fuel, and digestate; a source of nutrients that can be used as a powerful fertiliser or soil conditioner. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester.
