We report the potential way to increase the value of waste products from household silk industry in Thailand, which may shed light on extra income for farmers. From the preliminary results on bone-replacement material, it was found that hydroxyapatite can be grown or coated on silk fibroin threads via crystal growth and dip-coating techniques, respectively. They are novel composite materials for bone-replacement implants as a combination of high mechanical properties and superb biocompatibility. Drug release material is a transparent fibroin-based film, owning high elasticity and hydrophilic behavior, which are important for controlling drug molecules during diffusion. Finally, the medical cosmetic products are based on the nano-powder of sericin synthesized via a new simple, low-cost method that offers plenty of the sericin powders.
