As a way to encourage recycling, and to add flavor to its stories, the UK Metro Herald
announced plans to issue the newspaper in edible form:
The printing process sees ingredients such as corn starch, vegetable oil, gum arabic, water and citric acid cooked into a stodgy paste and thin sheets. The paste is poured on to the sheets under silk meshes arranged in the form of headlines, pictures and articles. Printing takes a few hours overnight – several seconds to print each page and slightly longer to dry. The finished products are even given a light vanilla scent.
