How about this? Self-cleaning plates and cups (dishes) made solely from cellulose that does not need to be washed. You know what that means, right?
You save on water and you also get to avoid all those nasty chemicals loaded in dish-washing detergents.
The dishes have a superhydrofobic coating that makes it possible for them to reject dirt, like a lotus leaf.
And they are from the efforts of Tomorrow Machine, a Swedish design studio based in Stockholm & Paris, and Innventia, also a Swedish research and development company that works with innovations based on forest raw materials.
The self-cleaning dish is just one of many such ideas from both companies.
