Our willow filtering plantation process

THE NUMBER OF WASTEWATER LITERS THAT A WILLOW CAN TRANSPIRE IN A DAY

Our willow filtering plantation process consists of a fast–growing shrub willow plantation cultivated using an intensive short–rotation approach and submitted to a precision irrigation of contaminated effluents.

Our process, through soil, soil microorganisms and willows combined action, allows the recovery, treatment and volume reduction of wastewater effluents.

We have a leading–edge team and specialized equipment to realize your projects, from planting to harvesting. In addition, our nursery, which produces several million willow cuttings annually, can guarantee you quality planting material and offer you the best varieties available on the market.

The advantages of the process

Partial or complete reduction of the effluent volume by evapotranspiration.
Vegetalized treatment process with low capitalization and operating costs.
Circular economy: Valorization of the effluent resources by the production of high added–value products with willow biomass .
Carbon sequestration in willow biomass.
