Ricicla quella cicca

La gomma da masticare oltre ad essere fastidiosa quando ti si attacca alle suole e poco elegante quando tappezza le strade ha anche un problema di biodegradabilità che la rende inquinante e particolarmente costosa rimuoverla dai marciapiedi.
Ora si inizia a pensare a produrre gomme da masticare senza poliisobutilene o quanto meno riciclarne il più possibile.

There's probably not enough gum in the world to create a major environmental issue, but the volume of waste is not entirely insignificant. Worldwide, humans chew about 560,000 tons of gum each year. To put that into perspective, Americans threw away 30 million tons of plastic in 2009, about 28 million tons of which wound up in landfills. If you want to make a rubber-to-rubber comparison, American toss out 290 million car tires every year, weighing in at over 3 million tons. Recycling is common, though: Only one-tenth of those tires are buried in landfills each year.
