Japan's Shokubutsu Hana, the Pasig River Rehabilitation Commission, Vetiver Farms Philippines, and agency TBWA\SMP teamed up to create a floating billboard to soak up pollution and discourage people from throwing trash in the river. It was made using vetiver, a type of grass that can absorb toxic materials and help to reduce pollution. Spelling out "Clean River Soon," according to the brand the installation is capable of cleaning between 2,000 and 8,000 gallons of water every day. Eh, not so sure about that one, but if the plants were selected appropriately, this is an awesome way to market a business while phytoremediating nasty water.
