Husk as a substitute for polystyrene: packaging materials with a good conscience
Expanded polystyrene (EPS) packaging is very practical, but it is made from petroleum and is not very environmentally friendly in other ways either.

The Stuttgart-based start-up PROSERVATION has developed an ecological packaging material made from grain husks that could replace EPS and be just as effective.
