What is AD?

Anaerobic digestion (AD) is the environmentally-sustainable method of breaking down plants and wastes into biogas.

AD is a natural process that sees micro-organisms break down organic matter in the absence of oxygen. This gives off a methane-based biogas which is then collected.

The produced biogas can be burned locally to the AD plant, or injected into the gas main grid after cleaning.

AD and biogas combine to form a renewable energy system, that is to say they are fuelled by energy sources which are able to be replenished.

Renewable energy is vital in today’s world, where greenhouse gasses are rising at unsustainable levels.

Methane is about 30 times more warming to the earth than carbon dioxide (CO2). Indeed, a single cow produces more CO2-equivalent emissions per year than an average car, because of the methane they produce.

When biogas is burned to produce electricity, the harmful effects of methane are eliminated, and therefore AD and biogas’ carbon footprint per kWh of electricity is significantly less than that of fossil fuels.

AD is being taken up by more people, businesses and farms every year. It can help with increasing levels of livestock, as well as tightening regulations on water pollution and odour management.
