In Japan, they came up with moisture-resistant paper to replace plastic

Japanese scientists have developed Choetsu spray coating, which gives the paper the useful properties of plastic - water resistance, strength and flexibility. Fluid-treated paper could be a sustainable replacement for some container plastics - it's completely biodegradable. Over time, substances from the coating will decompose into carbon, water and silicon - they are not dangerous to the environment. In the future, the scientists want to adapt Choetsu to other materials such as glass, ceramics and plastics. The spray will protect them from dirt and make them more durable.
