Voghera (Pavia) – The absolute evil hides behind the image of a tiramisu. The photo of the cake that every Italian family has prepared at least once was stuck on a hundred thousand covers polypropylene: will close as many pans of the same substance. The polypropylene won the Nobel prize for chemistry with the Italian Giulio Natta. But today is the absolute evil. So the workers of the Piberplast of Voghera, they decided to call the polymer that has so far guaranteed their salaries. Polypropylene, for those not in the know, is the plastic. The more plastic that holds the mascarpone with which to prepare the tiramisu, which insulates from hot bonbon to ice cream, chocolate-coated, which lengthens in time the freshness of the mozzarella cheese. The same plastic that in excessive quantities it ends up in the seas, and that, for this, was put on the index.
