The yearly consumption of coffee in Great Britain is around 136,000 tons. During the production and and roasting processes, large amounts of organic waste accumulates. This coffee waste product can be used for energy production in a sustainable manner. A prime example of this is the 2G project with Kraft Foods US Production Ltd. in Banbury.
The 45ºC warm coffee-waste mixture is converted within 10 hours into biogas via the UASB Reactor. The procedure is particularly energy-efficient as the reactor doesn’t require any additional heating, as the process temperature is already 45ºC. The created biogas is used to operate a block heat and power plant (Agenitor 306) to produce peripheral power and heat.
The Agenitor 306 is equipped with a downstream steam generator which converts engine exhaust into saturated steam. Lost heat from the engines provides biological filtration for the hydrogen sulfide and supplies hot water. Along with this, 1,400 tonnes of greenhouse gases can be saved through CO2 neutral energy production. With the implementation of the project, Kraft Foods showed that environmental and business objectives can be closely connected to each other.
