On 16 September 2026, from 14:00 to 16:00 (online), we will host a free webinar dedicated to a topic that is of growing interest worldwide: the validation of odour dispersion models using the grid method defined in EN 16841‑1.

   Consultants run odour dispersion models around the world, but because odour concentration is difficult to measure reliably in ambient air, there is no practical way to know whether the model predictions are right or wrong. With the approach developed and applied in Germany, Austria and Switzerland, along the last over 40 years, it is possible to check the performance of a model and verify whether an odour dispersion assessment has been done correctly against field measurements.

   Following the success of ODORA24 and the subsequent cancellation of ODORA25, Olores.org resumes the organization of its international odour conference with a new edition: ODORA27, which will take place from 10 to 11 November 2027 at the Euskalduna Conference Centre in Bilbao, Spain.

    ODORA27 will once again bring together international experts in odour management, including researchers, technicians, consultants, public authorities, and professionals from sectors such as waste treatment, wastewater, the agri-food industry, livestock, etc. On this occasion, the conference will be held entirely in English, reinforcing its international scope and facilitating the participation of experts from around the world.
