Selection criteria for odour abatement technologies have been traditionally economic and based on the flow rate to be treated, odour concentration (or of a certain surrogate such as H2S) and removal efficiency. However, nowadays social and environmental aspects are starting to gain importance.

Odour abatement systems are designed to operate over long periods of time (20-30 years) and under dynamic scenarios and conditions. Therefore, an economic analysis of sensitivity of the operating costs towards different design and operational parameters is crucial.

In Chile odour issues are becoming critical. The community is putting pressure on authorities and industry is being forced to take actions in order to minimize odour nuisances. There are approaches that allow delivering "reliable" results such as odour dispersion modelling, yet the question remains on how reliable the result of modelling can be. Are the results of modelling a true representation of the real odour impact and –most importantly– nuisances? In order to check the results obtained from a dispersion model, and validate how representative they are, it is essential and necessary to verify these. In this paper two case studies are presented that illustrate how methodologies by panel field can validate parallel modelling approaches. In both case, validation process was a valuable tool for detecting errors and obtaining reliable results. We conclude that modelling results must be validated by another methodology or they can be clearly misleading.

OdoWatch on Watch for Compost Odours

on .

 

The Edmonton Waste Management Centre (EWMC) of Edmonton, Alberta, Canada, is a unique collection of advanced waste processing and research facilities.  Owned and operated by the city of Edmonton Waste Management Services, the EWMC is an integral part of Edmonton’s sustainable approach to waste management.  The Centre is 233 hectares in size – 25 hectares is devoted to their composting facility, and is the largest of its kind in North America. 

Odotech, a Canadian Company that produces the e-noses, announces the installation of one of their largest OdoWatch systems to date, at the EWMC. The OdoWatch system is designed to track odours from the recycling area, material transfer station and working face of the landfill.

The Edmonton Waste Management Centre, world-renowned for their innovation in waste management, has selected Odotech to help them better understand and efficiently manage, the odours emitted from their site. With greater knowledge about sources of the odours, more effective measures to mitigate those emissions can be developed.
