Plastic-Free Packaging Made from Algae-Derived Films

Single-use plastic packaging is a major contributor to environmental pollution. My concept is to create biodegradable packaging films made from algae-derived polymers. Algae can produce polysaccharides like agar and alginate, which can be processed into thin, flexible films suitable for food packaging. The production process would involve harvesting fast-growing algae, extracting its polysaccharides, and then processing these into sheets. These films could be designed to dissolve in water or break down into harmless compounds after disposal, reducing landfill waste. The films could be customized for different products—thicker for grocery items like fruits and vegetables, or thinner for wrapping snacks. The challenge is achieving the same durability and moisture resistance as conventional plastic films while keeping production costs competitive. However, with the growing demand for eco-friendly alternatives, algae-derived packaging could offer a practical way for businesses to reduce their environmental footprint, especially in the food and beverage industry.
