OdoWatch System

3 electronic noses, OdoWatch® software for modeling atmospheric dispersion of odors, weather tower

Background

The landfill site, located in Lançon-Provence in the south of France, includes a technical landfill for household waste and a composting site for handling the sludge from a wastewater processing station.

Odotech Assignment

Odotech installed a continuous measurement OdoWatch® system for odor monitoring, comprised of 3 electronic noses positioned at the edge of the 3 principal sources of odor emissions: the composting windrows, the fresh sludge reception zone and the edge of the landfill burial zone. With the help of the OdoWatch® software, atmospheric dispersion of the odors was calculated in real time and allowed visualization of the local environment's zones affected by site emissions. In conjunction with technical installations at the facility itself, a neighborhood committee was established to allow the monitoring of odors perceived by the residents of Val-de-Sibourg.

Principal Outcome

After 1 year of monitoring, cross analysis of OdoWatch® results and those of the neighborhood committee produced figures suggesting that about 80 % of the odor episodes pointed out by the committee members were not attributable to the composting site, but to other sources of odor in the surrounding area.
