Jihane Saad from IRDL reveals a reduction of 5 log10 of enterococci in methanization in Benin

The thesis of Jihane Saad, defended at the National Polytechnic Institute of Brittany, demonstrates a significant reduction of 5 log10 of enterococci in methanization effluents thanks to thermal treatments. This advancement, validated by the ABES/STAR network, could transform agricultural waste management in Benin by improving health safety.

Agricultural methanization, although effective for managing organic waste, raises health concerns related to the presence of pathogenic bacteria. Jihane Saad targeted enterococci and clostridia, problematic bacteria in methanization effluents, to assess the impact of innovative treatments on their inactivation. Food safety and public health are major issues in this context.

The research results show a reduction of 5 log10 of enterococci thanks to thermal treatments, indicating their effectiveness in eliminating these bacteria. This discovery paves the way for safer treatment protocols for effluents from methanization, thus contributing to the health safety of agricultural products and protecting human and animal health.

The implications of this research are strategic for decision-makers and stakeholders in the agricultural sector. By integrating these innovative treatments, it is possible to valorize waste while reducing health risks. Investors can seize this market opportunity by supporting projects that improve health safety in agricultural methanization.
