The Braun Envi urban dustbin concept surely takes things to new heights – it not only provides a decent space for you to throw away your rubbish, it also promotes “composting from biodegradable waste”. For example, whenever you toss your apple core inside, the bio-reactive substances based on photo catalysis will get to work by rehashing such trash as compost. Substances within will do their bit in removing odors while speeding up the process. Hopefully this concept can materialize sometime in the near future, where huge versions of these allow folks to throw in their biodegradable trash that can be collected and used afterwords as compost.
