Some background on The Guardian’s recent decision to begin using plastic derived from potatoes to wrap its supplements:
Last year we used approximately 25 tonnes of plastic for wrapping, which is about half a tonne a week. We knew we had to find an alternative. The newsprint we use for newspapers, however, is more than 70% recycled, and sourced in a way that retains biodiversity, which is really important to us. The new compostable wrapping film we now use is made from waste potatoes left out of the food chain in Eastern and Northern Europe, it is processed to release the starch and manufactured into granules.
