Registration for the EN 13725 Interlaboratory Comparison ILC2016 is now open

ilc 2016 olfasense   The Interlaboratory Comparison for Olfactometry (ILC) based on EN 13725:2003 has been announced for 2016 and the company Olfasense is behind the organization. The proficiency tests allow laboratories to demonstrate compliance with its performace requirements and compare the performance of their laboratory internationally.

   This proficiency test allows laboratories to demonstrate compliance with its performace requirements and compare the performance of their laboratory internationally. The participation in Proficiency Testing (PT) for laboratories accredited to ISO17025 is not facultative. In addition, it is a nice exercise to have more information about the performance of your lab.

II Chinese-Austrian Workshop on Environmental Odour in Shanghai, China, the 20th & 21st September 2016

2nd chinese austrian workshop   This 2nd Chinese-Austrian Workshop on Environmental Odour is organised by well crowded bunch of universities and technological centers of China and Austria. This second workshop is organized by the Eurasia-Pacific Uninet, the Tongji University, the Fudan University, the University of Veterinary Medicine Vienna, the Central Institute of Meteorology and Geodynamics of Austria, the University of Innsbruck and the Austrian Academy of Sciences, will take place in the Tongji University in Shangai, China, the 20th & 21st September 2016. 

   Environmental odour is a major concern of residents in the vicinity of odour sources. This workshop will treat the entire chain from the odour source, the dilution in the atmosphere up to the perception of odour by the nose of residents. The workshop will include the characterization of the odour source by emission factors  and emission models, the use of dispersion models to describe the transport and dilution in the atmosphere, the assessment of the relevant stimuli concentration and the odour impact criteria.

A landfill in US reached a $2M settlement in a lawsuit about odours

tullytown landfill   Tullytown is located in Burlington County in the U.S. state of New Jersey. There, the corporation Waste Management, Inc, (WM) runs the Tullytown landfill since the eighties. This is one of the 293 active landfill disposal sites that this company manages, but this one is special because this landfill receives several odour complaints from the community. The odour annoyance was so noticeable that the Waste Management had to agree to pay $2 million to settle a class-action lawsuit filed on behalf of residents on both sides of the Delaware River who claimed that noxious odours lowered property values and affected their quality of life.

  The Houston based corporation Waste Management, Inc (WM) was founded in 1971 and runs 293 active landfill disposal sites. Not many companies in the world run this number of landfills. One of their landfills is located in Tullytown, New Jersey and the residents around this area have long drawn complaints about the smell of this Landfill.

   As you probably know, we organized an International Conference about Odour Management in Bilbao, Spain, not long time ago.

   We say "international" cause around 12 countries attended that event, but unfortunately this event was not bilingual (such as the one we did in Chile), but just in Spanish. We apologize for that, and we hope next one is bilingual again.

   Saying that, we are very happy to share with you the abstracts of the presentations, and guess what? some articles are in English!

   Enjoy them!


Coexistence between a sewage plant and its surrounding. Redesigning Galindo WWTP

sesion07 lopez03   Galindo waste water treatment plant was designed in the 1980s on the plot of a dump in a highly industrialized area. The industrial conversion plan and urban development have remodeled the surrounding landscape, making it an urban established plant, causing conditions to which the plant could not offer solutions.

   Aware that the plant should not produce a significant change in the quality of resident’s life, the Consorcio de Aguas Bilbao Bizkaia (CABB) has designed an ambitious plan of minimization of the odor significance, scheduled in four stages.

Odorants atmospheric dispersion forecast around a pulp mill plant

sesion04 cartelle04   Traditionally, pulp mill plants using Kraft process produce TRS (Total Reduced Sulphur) odorants emissions; this is the case of ENCE-Pontevedra plant.

   In this work, PrOlor operational system for odorants atmospheric dispersion forecast is presented, based in WRF/CALMET/CALPUFF models, and applied to prevent sporadic odor episodes around that plant.

Case: Monitors inMMAR® - Tool for the gas monitoring and operational control

sesion04 vergara11   While there is currently a huge gap between odor and gases, since the smell is a complex mixture of gases which are capable of interact between each other. Therefore various gaseous compounds might generate different odorant stimuli than the single gas compound, so you may consider that monitoring gaseous emissions as a valid alternative as an operational tool.

   In this context, Ecometrika has been worked in the development of online monitoring equipment.

Activated sludge recycling and oxidized ammonium recycling: innovative strategies for odour prevention in WWTPs

sesion05 muñoz05   Odour control is an increasing concern in WWTPs. Physical/chemical end-of-the-pipe technologies for odour abatement are relatively expensive and present high environmental impacts. Biotechnologies, on the other hand, have recently emerged as cost-effective and environmentally friendly alternatives but are still limited by their investment costs and land requirements. A more desirable approach to odour control is the prevention of odorant formation.

   In WWTPs, where different biological processes take place and many streams are available, there are opportunities to re-design processes in order to minimize odour generation. This work explores two alternative strategies for odour control.

Setting-up of a methodology for odor dispersion studies with sub-hourly temporal resolution

sesion04 uriarte02   The current problems in relation to odor pollution episodes make it necessary to have methods to assess odor impacts. Such assessment can be performed using dispersion models that allow to estimate odor concentrations considering the emissions, the meteorology and the topography, among other data.

   Pollutant dispersion modeling is usually based on minimum averaging times of one hour; however, some pollutants require shorter averaging times, as it is the case of odors. Recently, the Atmospheric Research Group of the Faculty of Engineering of Bilbao has set up a methodology to perform dispersion studies using sub-hourly temporal resolution.
