Cut and pierced cocoons are the raw materials for production of spun yarn and handicrafts of making good-looking value added products like garlands, bouquets, flower vase, birds and greeting cards etc. which are sold at a premium. Silk waste is well utilized in the production of spun silk fabric, ornaments, parachutes and cosmetic industry. The value of sericulture activity has increased by 10–25 percent as a result of the use of its by-products. Silk wastes have promising applications which broadens the sustainability of sericulture industry and thus prove to be remunerative in earning an additional income.
