Water Purifying Plant Billboard is Trying to Clean Up One of Manila’s Most Polluted Rivers

A floating billboard from the Japanese beauty brand Shokubutsu HANA was recently installed on the extremely polluted Pasig River in the Philippines. The billboard is made from a type of grass that can absorb toxic materials and help to reduce pollution.
Vetiver, a perennial, non-invasive grass often used to treat wastewater and stabilize landfills and garbage dumpsites, has been shaped with the simple message, “CLEAN RIVER SOON.” According to Hana’s website, the billboard is able to clean 2 to 8 thousand gallons of water per day, thanks to its ability to tolerate high levels of nitrates, phosphates and heavy metals.
While this particular billboard was created to fit with Hana’s belief that healthy beauty can be brought about by the restorative power of nature, it’s also in line with a recent trend to create restorative advertising.
The billboard is the first of its kind in the Philippines, and came about from a collaboration between Hana, The Pasig River Rehabilitation Commission, Vetiver Farms Philippines and the advertising agency TBWA\SMP. More water billboards are planned for various sections of the river.

A Billboard That Does Good

A giant poster that uses nanotechnology has been created by a scientist and an award winning poet from the University of Sheffield.
The two professors came up with the idea of a poster absorbing poisonous compounds from the air with the aim of cutting disease and saving lives.
The poster can absorb poisonous compounds from around 20 cars each day if put by a busy road.
The 10m by 20m poster is coated with microscopic, pollution-eating nanoparticles of titanium dioxide. When the light hits the nanoparticles, they react with oxygen, and wash the pollution out of the air.
Although the poster does not filter out all the pollutants from traffic, it does remove nitrogen oxides which have been linked to breathing problems including asthma.
A poem by Simon Armitage, called ‘In Praise of Air’ features on the poster.
The poster will be on display in Sheffield for the next year.
