Grays Waste use the latest technology, Anaerobic Digestion, to process all the food waste that is collected from our customers.
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.
Just one litre of used cooking oil can generate enough electricity to light a 20W energy saving light bulb for over 225 hours.
Grays Waste Services have been servicing the waste management needs of London since 1947.
We are now proud to be one of the leading specialist food waste and category 3 waste collection companies...
"Our family has been using Grays Waste since the 1960's. Despite getting other quotes over the years, we've always found Grays to offer the lowest rates. To remain competitive over 50 years takes some doing, and it shows how important it is for Grays to always stay ahead of their competition."
"We had several quotes in for setting up a weekly food waste collection. Grays Waste were the lowest, and we’ve not had any issues over the last 18 months of using the service."
"Knowing that all the food waste generated by our chain of restaurants is disposed of in the most environmentally friendly way means we can feel better about doing what we can for the environment and everyone’s future. It’s good to know that Grays take the environmental aspect so seriously."
