About the project Edit

Supported by several major research programs around the world since the 90s, phytoremediation, or filtering gardens, consists of all the technologies that use plants as the main agent for treating pollution. Phytoremediation aims to preserve essential resources such as water, soil, and air but also the social, economic and ecological value of the landscape of treated sites. The principle of filtering gardens was created by Phytorestore, a company specializing in the implementation of pollution control projects.

One of the best known examples of phytoremediation is the water treatment program in New York city. Instead of building sewage treatment plants that would have cost $8 billion, it acquired local agricultural and forest areas, in order to ensure proper management and purification treatment of the city's water at the source. When it comes to wastewater, plants help clean up areas flooded with petroleum, chlorine, etc.


In what ways is this project unique and creative? Edit

Phytoremediation is a creative solution that helps to revitalize polluted soils in a natural and environmentally friendly way. Phytoremediation goes further than just treatment mechanisms - it uses different trapping techniques and mechanisms of accumulating pollutants in plants. It makes it possible to restore urban spaces while incorporating an ecological and landscape-friendly concept.

What is the social value of this project? Edit

Phytoremediation enables us to use plants to clean up the environment, instead of using chemical methods of synthesis, or processes that pollute themselves or require energy. It also gives nature its space back reclaiming its rights: tadpoles, fish, birds, insects, fertile land. Thus completing the ecosystem and allowing life to reorganize itself.

What is the potential of this project to expand and develop? Edit

Several cities use phytoremediation - partially or fully: Honfleur (France, Normandy), Begles (France, Gironde), Rønnede (Denmark), Suzhou (China, Jiangsu), and Fuyang (China, Zhejiang).
