Dispersants
By promoting the dispersion of oil in the form of microdroplets in the water column, dispersants increase its "dilution", stimulate and accelerate its degradation in the natural environment and reduce the chances of large-scale oiling of the shoreline
Standardised tests
Aims
Evaluate the effectiveness, toxicity and biodegradability of freshwater and marine dispersants under standard conditions
Check dispersant stocks at regular intervals to determine the effect of weathering on their effectiveness and toxicity

Custom tests
Aims
Test, develop and compare bio-based or chemical dispersants in a controlled environment and under reproducible conditions, using test benches and protocols specifically designed to meet the client's need
Study the impact of dispersants on the environment and optimise their use

Deployment tests
Aims
Study the effectiveness of dispersant-oil combinaisons under realistic conditions, reproducing cold, temperate or hot seawater or freshwater environments, as well as turbid areas. Investigate the possibility of implementing subsurface dispersion.
Each test is tailored to the client's needs.
