Swedish-based Whitelines has found a great way to reduce the environmental impact of paper usage by simply flipping common sense upside down. Instead of bleaching the entire paper before printing dark lines on it, Whitelines basically just bleaches the lines. The result is a typographic design experience that will help any piece of writing look better.
Whitelines products are seen used at business schools and company letters as a way to brand themselves as eco-aware. Whitelines paper is only a bit more expensive than regular paper, but way cooler.
