Stop single-use plastic: cutlery, glasses, plates will no longer be placed on the market
An ounce is one of the units of measurement of mass and is equivalent to 28.35 grams (28.3495231 to be precise). Precisely for this reason, glasses have irregular measurements for our standards: when we pour wine into the plastic glass (biodegradable and compostable) we must stop at the second line, or 5 ounces, corresponding to approximately 150 milliliters. The line closest to the edge is 12 ounces and is the indication for the quantity of beer. In Italy, classic white glasses are much more common, with many smaller circles and also in this case the reference is the unit of measurement: half an ounce for each line.
We also remember that plastic glasses can no longer be produced unless they are biodegradable and compostable. Single-use was banned in January 2022 in our country and it was a significant step also because Italy has a close connection with this type of plastic. The inventor of polypropylene, the white material that characterizes plates, glasses, forks, knives and all plastic products designed for food use, was an Italian: Giulio Natta, winner of the Nobel Prize in Chemistry in 1963.
