Forest/domestic waste as a source of natural dyes.

Abstract

Natural vegetable dyes have gained importance all over the world after a lapse of more than a century due to their eco-friendly nature. India can play a vital role in this field on account of its varied climate and rich flora. Forest and domestic wastes can also serve as a potential source of natural dyes. This communication deals with some forest/domestic wastes, including: fruit rind of bel (Aegle marmelos), anar (Punica granatum), sharifa/sitaphal (custard apple, Annona squamosa), amaltas (Cassia fistula) and imli (Tamarindus indica); cutch waste (the waste left after extraction of katha from Areca catechu wood); florets of safflower (Carthamus tinctorius) and marigold (Tagetes erecta); dried bark of Eucalyptus; fruit pulp and seeds of amaltas; and the upper dry scales of onion (Allium cepa).
