Sustainable Infrastructures Grand Prize winner of the Green Solutions Awards 2017: Filtering Gardens® (Brazil)

Filtering Gardens® is a biotechnology developed by Phytorestore. It uses humid ecosystems and phytoremediation to clean up waters and make them reusable again while recreating natural green spaces.

These filtering gardens are made of a series of pools filled with special substrates topped with local plants. These plants are carefully selected. Grey and rain waters flow through the substrates and the biological interactions of the roots treat the waters, without any addition of chemical, bacteriological, biological nor artificial compound. The efficiency of the process relies only on natural properties and human knowledge of that process. Thanks to this process, sewage networks receive less water to treat.

The esthetic result is a lot of green, with a wide range of indigenous species of plants favouring the development of local biodiversity while improving the quality of water in the region and contributing to cooling the microclimate. 

Filtering Gardens® is highly replicable and adaptable to a large number of places and it can help the development and protection of their specific biodiversity. It also contributes to raise awareness among the populations on this topic through educative programmes. Its carbon footprint is very low and even generates carbon credits.
