Anaerobic digestion or “methanisation” is the use of microorganisms to break down organic matter under controlled conditions and in the absence of oxygen. This process is implemented in waste treatment and recycling, a sector which is enjoying high growth. However, little data exists on the occupational risks associated with anaerobic digester units.
INRS has launched a new four-year study, with the aim of better assessing and better preventing these risks. This study will be in three parts: mapping the sectors of activity in question and the anaerobic digestion processes implemented; sampling and analysing the pollutants in targeted sectors; and then developing appropriate prevention solutions.
The conclusions of the study will lead to recommendations intended for professionals in industry and for OSH specialists. They should, in particular, feed into the work by the group of experts from the French OSH network steered by INRS.
