London Stansted airport is set to become the first only airport in the world to convert all its coffee waste grounds to solid biofuels after a successful trial with Cambridgeshire-based bio-bean, the world’s largest recycler of coffee grounds.
Where does the coffee waste go?
Passengers at the airport currently drink over six million cups of coffee a year as they pass through the terminal. This creates a shocking over 150 tonnes of coffee waste. The partnership, which began on 21 October will see all 21 of the airport’s coffee shops, restaurants and bars segregate all spent coffee grounds before being transported to the bio-bean’s hi-tech processing facility near Huntingdon, Cambridgeshire.
What does the coffee waste turn into?
Once the grounds have reached the facility they are converted into Coffee Logs, each made from the grounds of around 25 cups of coffee. They are then used in domestic wood burners and multi-fuel stoves as a more sustainable and environmentally. This is a much friendly alternative to conventional fuels. Recycling coffee grounds this way saves a massive 80% on CO2e emissions than if they were sent to landfill and 70% than if they were sent to an anaerobic digestion facility and mixed with food waste, which is what used to happen before the recycling.
What is this for?
This new scheme is the latest addition to London Stansted’s award-winning ‘zero waste to landfill’ policy and offers an even more efficient and sustainable way to transform waste into energy. In addition to the start of the new scheme, London Stansted is giving away around 2,000 of the new Coffee Logs to all staff and local residents in time for colder weather over the winter months.
Words cannot ‘espresso’ how much we love this idea, what are your thoughts?
