Ahimsa silk

Kusuma Rajaiah, a government officer from India's Andhra Pradesh state, applied the theories behind the Ahimsa way of life to the making of silk and found that it was possible to create silk without killing the creatures that created it. Traditional silk manufacturing methods involve boiling the cocoons of the silkworm and then sorting out the threads to be used later in production. Rajaiah's idea involves a gentler method, specifically letting the worms hatch and then using the cocoons once vacant. He started deploying this process in the year 1992 and has hence been supported by a larger community of people interested in the welfare and rights of animals and non-humans.
