Viable, Environmentally Friendly Alternative to Polystyrene Foam

An environmentally friendly foam was developed that can be used as an alternative to polystyrene foam, or Styrofoam™. The foam is made mostly from nanocrystals of cellulose, the most abundant plant material on Earth. The researchers also developed an environmentally friendly and simple manufacturing process to make the foam using water as a solvent instead of other harmful solvents.
