FAQ's

What is Anaerobic Digestion?

Anaerobic Digestion (AD) is the process of decomposing organic materials such as food waste, manure and animal by-products in an oxygen-free environment to produce biogas and liquid residuals.

What is biogas?

Biogas is a natural by-product of Anaerobic Digestion and is made up of methane and carbon dioxide. It is a safe, sustainable fuel which can be used for numerous purposes including powering gas turbines, generating electricity and as a heating fuel to name but a few.

Are there any other by-products of AD?

In addition to biogas, the other by-product of AD is a liquid mixture known as ‘digestate’. This liquid contains the water and minerals from the digested waste which makes an excellent fertiliser and soil conditioner.

Is the digestate eco-friendly?

Yes. Anaerobic Digestion kills the dangerous pathogens that are present in the waste. This means that when the digestate is used on the land, no pathogens are passed into the food chain.

What are the benefits of having an AD site?

Apart from the many benefits to the environment, the end products are potentially saleable items – biogas, liquid fertiliser and soil conditioner.

Will an AD site improve our carbon footprint?

Most certainly; for example, a plant saving an equivalent of 28,000 tonnes of CO²emmisions a year will have the same effect as taking 11,000 cars off the road.

Is an AD site licenced?

Yes it is; the Environment Agency also keeps a careful check on the facility to ensure we comply with the regulations at all times.
