This plastic is made from milk and it vanishes in 13 weeks

Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form a thin, durable material designed to mimic everyday plastic. In soil tests, the film fully broke down in about 13 weeks, pointing to a realistic alternative for single-use food packaging.
