The RITI coffee printer is an exciting new eco friendly printer currently being designed. It hopes to use old coffee grounds in its ink cartridges. Ink cartridges create a lot of non biodegradable waste that more often than not ends up in land fill sites. Ink is also a petroleum based product so in time will run out as its a fossil fuel, the production of ink also produces toxic waste products. Hence the need for better environmentally friendly and renewable printer options.
The printer will be made of recycled plastic and is designed to use minimal power it may also have the capability of using tea dregs as well as coffee.
While its still in the early stages of design its a novel and eco friendly idea.
