Waste-reducing spoil alerts
Due to vague labeling such as “Best Before” or “Use By” on food packaging, consumers throw away millions of pounds of good food each year because of uncertainty regarding edibility. A Brazilian company has stepped in to help solve this issue with the development of food packaging that changes color as food spoils. The packaging is built with sensors that can detect pH changes and other elements that suggest the food is turning bad. Teams in the U.S. and China are working on similar ideas to globally help reduce this huge food waste.
In Los Angeles and San Francisco, Toyota debuted 37 pollution-scrubbing billboards to promote the launch of their new hydrogen-fueled Mirai. Each board uses a titanium dioxide-coated vinyl to purify the surrounding air. When oxygen reacts with the energized titanium dioxide catalyst, nitrogen dioxide is converted to nitrate and removed from the air. Combined, the board has created nearly 25,000 square feet of pollution-scrubbing surface and has removed the equivalent of 440 vehicles’ worth of nitrogen dioxide emissions from the surrounding air.
World travelers swiping right
In Brooklyn, Delta and Tinder have created an unlikely partnership to help wannabe travelers create the perfect profile picture for their Tinder account. Delta has printed pictures of nine global locations (Eiffel Tower, Leaning Tower of Pisa, etc.) onto a wall that allows users to take selfies, making them appear as exotic jet-setters to prospective dating partners. The #DeltaDatingWall will be up all summer and on June 17 will partner with a professional photographer to help Tinder users get that perfect picture. The wall idea came about by observation of how prominent travel pictures are on dating profile sites.
