What is ‘bioremediation’? It is the ‘biodepollution’ of a contaminated environment (ground, body of water, water table,…). How does it work? With the help of little pollution “eating” organisms. Jean-Philippe Dos Santos, technical and scientific director of HTS BIO, talks to us about the current project in the Golfe-Juan port.
HTS MAG: Jean-Philippe Dos Santos, hello. Biodepollution –or bioremediation– is one of the HTS BIO’s jobs. Talk to us about the issues in the port of Golfe-Juan.
Jean-Philippe Dos Santos: The slow deposit of sediments in the Golfe-Juan port for decades has resulted in a worrisome reduction of the port’s depth. Indeed, the threat is so great that boats with a deeper draught may no longer be able to enter. This is why we visited the area – with the approval of the Maritime Alps County Council and the CCI Nice Côte d’Azur – to observe the trend and explore suitable solutions.
HTS MAG: How will you proceed?
JP.D.S: As a first step, tests are carried out. These tests, prior to a depollution project, enable us to do a complete lab analysis of the sediments so we can propose the most suitable biotechnological “solution.” In this case, the analyses revealed contamination…so it is important to act quickly!
HTS MAG: How can biotechnology overcome this type of pollution?
JP.D.S: With a “cocktail” of “pollution-eating” bacteria, capable of digesting organic matter. This reproduces the natural trend of biodegradation, but more quickly. In this case, we have determined that our product BIOSMOSE LAC®, which is as efficient in fresh water as in sea water, is the “cocktail” with the most suitable bacteria.
HTS MAG: What is BIOSMOSE LAC® and how does the product act?
JP.D.S: BIOSMOSE LAC® is a powder. The “cocktail” of micro-organisms is set on a mineral core of marine origin. The core’s porosity enables the “trapping” of pollutants so that micro-organisms can carry out their digestion work. In accordance with our philosophy, the selected bacteria are exclusively from class 1, meaning they are proven not to cause any danger to man or the environment.
Result: up to 90% of organic matters biodegrade naturally; a lower level of sediments and the depth of the port is equally increased. And all while preserving the marine environment.
HTS MAG: when will HTS BIO be able to begin depollution work at the Golfe-Juan port?
JP.D.S: HTS BIO convinced the project’s players and won the deal. Before beginning in situ, tests (which are currently in progress at the University of Nice) must show that the treatment is harmless. We expect to receive the green light to start work within the coming weeks.
