Anaerobic Digestion

Grays Waste use the latest technology, Anaerobic Digestion, to process all the food waste that is collected from our customers.

What is Anaerobic Digestion?

Simply put, it is a process that enables organic matter such as animal or food waste to be broken down to produce a methane-rich gas that can be used as a fuel and fertiliser. In even simpler terms, it turns waste into fuel.

Without processing organic matter or food waste by AD, the waste will end up in landfill creating significant levels of environmentally-damaging methane that is released into the atmosphere. Although methane is still created by breaking down organic waste at an AD plant, the methane gases are captured and utilised as a biogas rather than being lost in the atmosphere.

The UK is committed to producing more energy from sustainable renewable sources in order to limit climate change. In addition the UK also has a legal obligation under the EU landfill directive to reduce the amount of bio-degradable material being sent to landfill.
