Biorem Engineering, operator for more than 20 years in the sector of the cleaning of the ground and groundwaters polluted by hydrocarbons, has developed a portfolio of patented technologies in the field of the green chemistry which is defined by the product design and processes of synthesis making it possible to reduce or to eliminate the use and the generation of dangerous substances or poisons for the environment and the human health.Active from applied research until industrial application, the business model of Biorem Engineering evolved in the course of time. Of a company of cleaning, Biorem Engineering became a developer of technologies, solutions and products "ready to uses" to put on the global market by licensing or joint-venture in partnership with strategic industrialists or investors.Private actor familiar with the exercise of the technology innovation, Biorem Engineering is active in market segments with high added value like the depollution of the soil and groundwaters, the industrial processing waste as well as other applications in agriculture and in the pharmaceutical sector. Technologies Oxygel, Oxygel +, Dechlorem or Biocat made it possible for Biorem Engineering to successfully carry out important works of in-situ depollution of the soil, basement and groundwaters polluted by persistent organic compounds, in particular on behalf of Coca Cola, Solvay, AXA, Crédit Agricole, GDF Suez.The clean-up operation of the basins of the hydroelectric station of Coo (which was finished in 2014), for a budget of more than 20 million euros, is the most important work of in-situ depollution (Polychlorinated Biphenyls PCB and mineral oils) ever carried out in Europe, as well in terms of technological performance as of treated volumes (179 000 tons of sediments polluted on a surface of 70 hectares). For recall, PCBs are persistent organic pollutants which organic accumulate in the living beings by causing cancer in particular and of the endocrinal disorders.
