A Plastic Alternative Made of Wood and Spider Silk

Nature has come up with many clever designs for materials with superlative properties. By combining two natural materials that boast excellent mechanical traits, wood and spider silk, researchers have made a material that could be a possible sustainable alternative to plastic.

The new composite, reported in the journal Science Advances, comes from could be used for medical implants, sutures, textiles, and packaging. But unlike the plastics that would normally be used for those products, the material is biodegradable and is not made from petroleum.
