Clean river soon

Can A Billboard Help Clean the Country’s Most Polluted River? How does one clean the Pasig River? A group of creative people found an unlikely solution: they put up a floating billboard. The billboard is the first of its kind in the Philippines. It is made of Vetiver, a perennial, non-invasive grass often used to treat wastewater and stabilize landfills and garbage dumpsites. The plant can tolerate high levels of nitrates, phosphates and heavy metals, absorb toxic materials and help reduce pollution even in water as dirty as Pasig river. The message of the billboard spells hope: CLEAN RIVER SOON. It is also a warning for people to think twice before throwing rubbish into the water. Based on research, a Vetiver system like this can clean 2 to 8 thousand gallons of water per day. The floating billboard made of pollution-reducing Vetiver was mounted last February 2014 through the combined efforts of Shokobutsu Hana, The Pasig River Rehabilitation Commision, Vetiver Farms Philippines and TBWA\SMP.
