CEHTRA at SETAC Europe 36: Poster Presentation on the “Rapidly Biodegradable” Criterion under the UWWTD

CEHTRA is pleased to announce its participation in the SETAC Europe 36th Annual Meeting, taking place from May 19–21, 2026 in Maastricht.

During the event, Floriane Demailly and Mylène Léger will present a scientific poster addressing the implementation challenges associated with the new “rapidly biodegradable” criterion introduced under the recast Urban Waste Water Treatment Directive (UWWTD).

📅 Poster presentation: Thursday, May 21, 2026🪧 Presentation ID: 7.02.P-Th299

The poster explores several scientific and regulatory questions linked to biodegradability assessment in urban wastewater systems, including:

• the interpretation of the “rapidly biodegradable” concept,

• the applicability of OECD biodegradability screening tests,

• the relevance of environmental fate modelling approaches,

• and the challenges linked to harmonized implementation across Europe.

The work also discusses the connections between the UWWTD framework and existing European regulatory frameworks such as REACH and CLP.

CEHTRA looks forward to exchanging with the scientific and regulatory community during the conference.
