# River Cleaning Billboards A Floating Water Purification Billboard is Making a Difference in Manila By Alyson Wyers | Published 2014-06-03 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/water-purification-billboard References: [psfk](http://www.psfk.com/2014/06/water-purifying-plant-billboard.html) & [facebook](https://www.facebook.com/VetiverFarmsPhilippines) Similar to an air cleaning advertisement in Peru, this water purification billboard is cleaning a river in Manila, Philippines. The floating ad is trying to clean up one of the country's most polluted rivers by purifying between 2 and 8 gallons of water daily. Floating on the Pasig River, the [floating water purification billboard](https://www.trendhunter.com/trends/floating-solar-still) is constructed out of a perennial grass called Vetiver that absorbs toxic substances and is frequently used to stabilize landfills and treat waste water. The billboard can purify so much water in a day due to its ability to tolerate large amounts of nitrate, phosphate and heavy metals. An example of [advertising for good](https://www.trendhunter.com/trends/scratchandsniff-ooh-campaign), the billboard reads 'Clean River Soon' and is possible due to a collaboration between the Pasig River Rehabilitation Commission, Japanese beauty brand Shokubutsu HANA, ad agency TBWA\SMP and Vetiver Farms Philappines. ## Trend Insights (Trend Hunter) - Score: 6.3/10 - Popularity: 94% | Activity: 87% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Eco-friendly Advertising:** Creating advertisements that not only promote a product or service but also contribute to environmental sustainability and impact. - **Green Infrastructures:** Developing sustainable infrastructures that provide both functional and environmental benefits. - **Water Purification Technologies:** Developing innovative technologies that can effectively purify polluted water sources while promoting environmental sustainability. ### Sectors Adopting This - **Advertising:** With the growing demand for environmentally conscious initiatives, advertising agencies can develop eco-friendly campaigns with a positive social and environmental impact. - **Infrastructure:** With the increasing concerns on environmental sustainability, businesses can focus on developing green infrastructures that can provide efficient and sustainable benefits. - **Environmental Technology:** Developing innovative and effective water purification technologies can open doors for businesses in the environmental technology field while contributing to social and environmental sustainability. ## Related on Trend Hunter - [Innovative Outdoor Advertising Campaigns](https://www.trendhunter.com/trends/outdoor-advertising-campaign.md) - [Lotus-Inspired Floating Water Purifiers](https://www.trendhunter.com/trends/floatis.md) - [Beer-Cooling Billboards](https://www.trendhunter.com/trends/heineken-billboard.md) - [Serum-Dispensing Billboards](https://www.trendhunter.com/trends/hydrating-billboard.md) - [Hydrating Outdoor Billboards](https://www.trendhunter.com/trends/bpm-pay.md) - [Water-Powered Air Purifiers](https://www.trendhunter.com/trends/airsancta.md) - [Billboard-Transformed Tent Shelters](https://www.trendhunter.com/trends/lifesaving-outdoors.md) - [Musical Monsoon Billboards](https://www.trendhunter.com/trends/brooke-bond-taj-mahal-tea.md) - [Sun-Framing Billboards](https://www.trendhunter.com/trends/daily-dose-of-vitamin-d.md)
