British authorities and environmental groups were welcoming the launch this week of the world’s first biodegradable chewing gum, which they say could help save some of the millions spent on clearing up the mess ordinary gum creates. The new gum becomes non-adhesive when dry and decomposes to dust within six weeks, a spokesman for Mexico’s Chicza Mayan Rainforest Chewing Gum told CNN. The makers of Chicza say it is the first biodegradable chewing gum ever sold.
