The 60 x 60 ft. plant billboard, located along Northbound EDSA-Forbes, utilizes a thriving species of Fukien tea plant, which absorbs air pollutants. According to botanist Anthony Gao, each plant can absorb up to 13 pounds of carbon dioxide in a year, on the average. “This billboard helps alleviate air pollution within its proximate areas as it can absorb a total of 46,800 pounds of carbon dioxide from the atmosphere, on estimate.” Gao says.
What’s the plant billboard made of?
- 3,600 pots of recycled Coke bottles
- potting mixture made up of industrial by-products and organic fertilizers (both stable and light-weight)
- bottles designed to contain the plants securely and allow the plants to grow sideways
- drip irrigation system operated on a schedule to distribute water with nutrients to the plants
