Innovative Biodegradable Film from Milk Protein and Volcanic Clay
- Researchers created a biodegradable packaging film using milk protein, starch, and volcanic clay.
- The film reduces water vapor permeability by nearly a thousand times compared to similar biopolymer films.
- It fully degrades in soil within approximately thirteen weeks, much faster than petroleum-based plastics.
- The film stretches over double its original length before tearing, due to the reinforcement from volcanic clay.
- Bacteria colonies on the film remain below ISO standards for non-sterile packaging applications.
This new biodegradable film offers a significant reduction in environmental impact compared to traditional plastics. By utilizing milk protein and volcanic clay, the material achieves remarkable durability and biodegradability without sophisticated production methods, making it accessible for broader adoption in regions with limited waste management infrastructure.
The study demonstrates that natural ingredients can replace conventional plastics, offering an eco-friendly alternative that degrades rapidly in soil while maintaining functional strength and flexibility. Source
