Indigo is a dye, originally produced from plant species such as Isatis tinctoria, Chinese Woad (Isatis Indigotica), and polygonum (Polygonum Tinctorium). Since the 19C synthetic Indigo has been produced unsustainably on a massive scale, to the extent that today billions of pairs of jeans every year are dyed with products which are harmful to the environment.
Recent international crop trials and research have shown that it is possible to produce Indigo naturally and sustainably in the EU. An enthusiastic response by the fashion and textile industries has meant that we can now expect natural indigo dyed products to become widespread in future years.
