Non-violent silk Non-violent silk, also known as peace silk, is a type of silk produced without harming or killing the silkworms. Unlike conventional methods, where silkworms are steamed or boiled to death, non-violent silk allows the worms to go through their natural life cycle before collecting the cocoons. According to PETA, up to 3,000 silkworms are killed to produce half a kilo of silk.
