Scientists Turn Milk Protein Into a Biodegradable Plastic Alternative—Here's How

Scientists created a biodegradable packaging film from milk protein, starch, and volcanic clay.
The material reduces water vapor permeability by nearly 1,000x compared to similar biopolymer films.
It fully degrades in soil in about 13 weeks—far faster than petroleum-based plastics.

The protein that keeps your yogurt thick and your cheese stretchy just got a new job: replacing plastic wrap.

Researchers from Colombia and Australia have published a study in Polymers detailing a biodegradable film…
