LiquiGlide: Nonstick coatings leave zero waste behind

The days of wasting condiments - and other products - that stick stubbornly to the sides of their bottles may be gone, thanks to MIT spinout LiquiGlide, which has licensed its nonstick coating to a major consumer-goods company. (Learn more about LiquiGlide: mitne.ws/1BTLIqK)
Developed in 2009 by MIT’s Kripa Varanasi and David Smith, LiquiGlide is a liquid-impregnated coating that acts as a slippery barrier between a surface and a viscous liquid. Applied inside a condiment bottle, for instance, the coating clings permanently to its sides, while allowing the condiment to glide off completely, with no residue. They can also design the coatings to be made entirely of food so it's edible and safe for consumer packaging of food-based products
