Vertical Ecosystem

Vertical constructed wetland

bcp5alchemia-nova has developed several innovative phytotechnologies to the point where they can be turned into commercial products. To this end the spin-off company blue carex phytotechnologies GmbH has been established. Principal among these innovations is the building integrated vertical ecosystem, which we call vertECO®. Its main purpose is to treat and clean greywater as well as industrial wastewaters. The purified water can subsequently be used to flush toiletts, for watering green areas and even for laundry washing. vertECO offers multiple addtitional benefits while being an affordable investment adjusted to customised design preferences.

To name the most important benefits:

  • water savings of 50% or more
  • improved and attractive living environment
  • evident commitment to the environment and sustainable business practices
  • microclimatic benefits, such as cooling and air humidification
  • reduced costs, preservation of natural resources and improved well being for people


vertECO has been optimised and validated in the course of the European joint research project demEAUmed. The project investigated practical and future oriented solutions for sustainable water management in touristic facilities, particularly in Mediterranean regions with water scarcity. The demonstration site is located at Hotel Samba, Lloret de Mar, Spain.

This robust and reliable solution offers important cost savings, very high pollution removal rates and low energy consumption per cubic metre of treated water. A combination with photovoltaics is possible to further reduce resource consumption. Buildings and facilities with high water consumption (like hotels for example) benefit the most from this technology. Another elegant feature is that water users are not subjected to any restrictions of lifestyle changes, in fact, their living surroundings are even improved.
