From Used Tyres to Printer Ink
Printer ink can cost as much as vintage champagne, reports New Scientist. So finding a cheap way of making it must be a great money making opportunity. Now three inventors from Derbyshire think they have found a way of doing just that. The solution? Extract the carbon from unwanted tyres to generate a cheap and plentiful supply.
The black carbon powder used in regular ink is refined from pure oil and the liquid used in cartridges is boiled down from a volume six times larger. On the other hand, millions of tyres are disposed of each year.
