Print Books vs. e-Books
How do new-fangled digital and old-fashioned print books measure up against green criteria? The main components of printed books are paper and ink. On average, each tonne of paper produces 3,300 kg of emissions and consumes 18 trees, 67,500 L of water and 9,500 kWh of power.
E-readers comprise several plastic, rubber, metal and glass components, which all have impacts in their manufacture. 'E Ink' technology, which enables the device to create and sustain an image, consists of a thin plastic laminate crammed with tiny capsules containing black (carbon) and white (titanium dioxide) particles.
