Description

In August 2020, the company Yara in France commissioned a pilot project to verify the treatment of the company’s effluents, which originated from its production system and were causing a significant environmental problem. Over two years, we successfully treated these effluents, as verified by external companies and confirmed by Yara itself. Additionally, we obtained a construction permit for a commercial phase, which was ultimately halted due to the company’s discontinuation of activities, despite having successfully met all objectives.

Impact & Result

From an environmental impact perspective, achieving the pilot's objectives meant that 300 m³ of wastewater per day could be treated viably, staying below the limits set by the relevant authorities and thereby preventing large-scale pollution. Furthermore, this scale would result in the capture of hundreds of tons of CO₂. On the economic side, studies conducted by accredited and independent organizations confirmed the suitability of the obtained biomass as a biostimulant.

Solution Spotlight

We are treating wasterwaters charged in Nitrogen and Phosphorus thank to microalgae-based cleantech. We are producing microalgae biomass. The cultivation of microalgal biomass in flat photobioreactors is a technology that maximizes the yield of these cultures while simultaneously addressing environmental issues, namely: water pollution and CO₂ capture. Additionally, the biomass can be used as a biostimulant and animal nutrition. Our solution adapts the production model to any of these purposes. We therefore contribute to the preservation of water resources and biodiversity (WATER, AIR, SOIL & COASTS) through a sustainable, circular and regenerative business model.
