A French chemical company
Saint-Vulbas
The R&D team of Séché Environnement is deeply committed to the development of innovative solutions for circular economy. Since its creation, Séché Environnement has applied a strategy of anticipation and technological innovation in order to reaffirm and strengthen its positioning as a specialist in waste markets, particularly hazardous waste. Séché Environnement pursues a collaborative R&D strategy with its partners, listening to the needs of its industrial clients and embarking them in the development of its innovative solutions. Our client has played a key role in expanding this project to an industrial scale, being the initial buyer for the recycled bromine. They participated in and pushed for the R&D work which led to the improvement of the carbon footprint of the process and the increase of the production capacity. With Maxibrome, we offer the first recycling method for bromine, which constitutes a major step in reducing the impact of the chemical industry.
By providing our client with circa 3,000 tons of recycled bromine per year, we are able to significantly improve their environmental footprint. Our recycled bromine enables our client to save more than 20,000 tCO2e/year compared to the use of virgin bromine processed in France, and even more if the bromine comes from another country. In addition, the use of recycled bromine enables our client to reduce its indirect water footprint by 45,000 m3 compared to virgin bromine.
Maxibrome combines a thermal purification technique with bromine concentration loops to recover 99% of the bromine contained in bromine-bearing brines (hazardous liquid waste generated by the pharmaceutical and chemical sectors, which was previously disposed of by incineration). The production capacity of the process enables to satisfy over 1/3 of the French bromine demand. In brief, polluted bromine-bearing brines are converted into purified and concentrated bromine brines that can be used by the industry. Maxibrome avoids the extraction of a rare natural resource by valorizing brominated waste. This process consumes less water and energy than virgin bromine production and participates in securing a European supply of bromine at a competitive price.
