The UK produces 500,000 tonnes of coffee grounds per year. At Marble Arch Place, Multiplex is working with ‘Bio-Bean’ to produce clean fuel from used coffee grounds. The site’s busy office and canteen produces about 30 litres of grounds a week in special collection bins, which are then picked up on a weekly basis.
This reduces greenhouse gas emissions by reducing the amount of organic matter that ends up in landfill. When organic matter ends up in landfill, it can produce methane gas, which is 30 times more potent than carbon dioxide when combined with trapped solar energy.
The end product (coffee logs) displaces conventional fossil fuels to produce energy with greatly reduced carbon emissions.
