Omniscientis project-final report

The EU-funded 'Odour monitoring and information system based on citizen and technology innovative sensors' (http://www.omniscientis.eu/, OMNISCIENTIS) project has made significant inroads in this regard with the aim of mitigating odour annoyance. To begin with, documents were developed describing the desired specifications for odour measurement, dispersion modelling and information technologies. In parallel, the needs and expectations of all stakeholders, including citizens, regulatory authorities and industrial bodies, were taken into consideration. Citizens' feedback on odour acceptability levels were gathered through smartphones and using the living lab approach. They were further combined with measurements from e-nose and odour dispersion models. Project members developed an Odour Information System that produces validated monitoring statistics and impact levels for local authorities to support environment-related decision-making and for citizens to give them feedback on their complaints. A mobile application is also available, used by citizens to perform odour related observations. Over 5000 observations were sent until now. Besides, two in-situ e-nose sensors and a meteorological station were installed and calibrated in the industrial site in Belgium, serving as pilot. Further 18 industrial parameters are collected in real time and 15 odour field surveys have been performed to understand odour sources and characteristics. The e-nose technology was optimised through tests and improvements to better understand relevant odour parameters at the second pilot site, a pig farm in Austria. Researchers adapted the GRAL-System pollutant dispersion model to develop a fast odour dispersion modelling system using harmonised real-time meteorological data and industrial emission measurements. It was validated with the odour emission rates, olfactometry campaigns and citizens observations. Most of the GRAL-solver components were implemented in Cuda with a speed improved by a factor superior of 100. Project activities were disseminated via project website and factsheets, 3 scientific papers, 13 international conferences and 3 user workshops involving selected citizens, technicians and authorities. Local environmental governance was enhanced through citizen empowerment via monthly meetings and specific methodologies. Better and timely feedback on undesirable odours arising from certain emissions will help in setting evidence-based acceptable odour limits. Ultimately, a particular attention have been addressed by all partners and in particular by involved SMEs in order to ensure the exploitation of the results and enabling the identification of concrete commercial opportunities that may be pursued after the project.Omniscienti
