The creation of Shiro Alga Carta dates back to the early 90s, when the Venetian Lagoon was clogged by algal bloom. In 1989, the Magistrato alle Acque of the Venice Council, the governmental body in charge of the problem, together with the Consorzio Venezia Nuova started to remove the algae to prevent the de-oxygenation of the Venice lagoon. Favini developed a new and innovative manufacturing process for the introduction of algae into paper. The raw algae are first dried and then milled in the paper mill to obtain seaweed ‘flour'. The flour is then combined with FSC fibres to make a high quality environmentally friendly paper. The outcome is a speckled paper where the speckles are the milled algae.
