There’s never been a better time to keep your neighbours happy and avoid costly social, regulatory and legal conflicts.

Odour emission measurement

Odour emission management

Measure… evaluate… control odours

Odour emission measurement is crucial to the regulation and control of environmental odours. Before you can define the extent of an odour problem, you need first to identify potential sources of odour emissions and understand their magnitude and characteristics.

Our environmental odour consultants are highly experienced in the measurement of odour emissions across all types of industry and will design odour sampling strategies to reflect your specific requirements.

All odour sampling and analysis is conducted in accordance with the EN 13725, European Standard for Olfactometry or other, published national and international technical and quality standards (such as EN 15259, EN 16911-1, VDI 3880, VDI 3884).

Sensory laboratory services

Sensory lab services

Sensory odour evaluation meeting the highest standards

Through our accredited odour laboratories specialising in sensory odour analysis, we offer you a wide selection of specialist odour testing services, including – but not limited to:

  • odour concentration analysis (ouE/m3) according to EN 13725
  • hedonic tone and odour intensity according to VDI 3882 and NVN 2818
  • odour type descriptions
  • odour threshold determination of pure substances and odour mixtures

And, thanks to our mobile odour laboratory, we can deliver global knowledge on environmental odour management in your local area – even in countries where there isn’t an Olfasense office.

Molecular laboratory services

Molecular lab services

Molecular odour evaluation using cutting-edge technologies

Olfasense is in a unique position to have both sensory and molecular odour analysis capabilities in-house. We use molecular analysis, like high-resolution GC-MS and GC-Sniffing, to characterise the chemical composition of air samples, and to determine the concentration of specific airborne pollutants.

Examples of services offered in the field of molecular odour evaluation are:

  • High-resolution GCMS, to characterize an odour in terms of specific VOCs
  • GC Sniffing, to identify compound(s) responsible for an odour contamination in an air sample
  • Gas chromatography coupled with ion-mobility spectrometry (GC-IMS), a very fast method to detect various substances within a couple of minutes
  • analysis of siloxanes in biogas and air samples
  • determination of specific compound groups (e.g. mercaptans and ketones)
Odour dispersion modelling

Odour impact assessment

Manage your odour impact risk

Assessing the odour impact of an industrial installation is a complex process, and we are happy to advise you on the most suitable solution for your business.

All our measurement techniques address the full range of factors to consider when conducting an odour impact assessment. These factors include the odour intensity, frequency and duration of exposure, offensiveness of the odour, and the odour sensitivity of those living in the affected environment.

One tool, specifically designed for odour impact assessment, is the Olfasense Online Field Inspection Manager

Odour dispersion modelling

Odour dispersion modelling

Sophisticated odour modelling technology

Our consultants have extensive experience with a wide range of odour dispersion models, including conventional Gaussian models (e.g. Aermod, ADMS), and more advanced ‘puff’ and ‘particle’ dispersion modelling techniques (e.g. Austal, CALPUFF).

This offers means to assess the way in which environmental odours and air pollutants disperse within the atmosphere, making sure your site is as environmentally sound as possible by assessing the odour impact, measuring compliance and optimising odour control strategies.

Odour mitigation and odour control consultancy

Odour mitigation & control consultancy

Odour control system assessment & performance testing

Olfasense has accumulated significant global experience in odour mitigation and odour control. We’ve seen many applications of odour mitigation and control technologies succeed and fail across many industry sectors, so we can confidently assess the options within the context of your particular area of work.

We also have a great deal of experience in the development of effective operational odour management plans. These documents define the measures that are put in place to minimise odour release and odour impact risk on a day-to-day basis, and to manage community communication and odour complaints.

Odour complaint management

Odour complaint management

If a site that you manage emits odours, it may affect local residents.

Our environmental odour consultants are highly experienced strategic communicators, and can provide detailed advice on how to optimise communications and manage crisis situations to ensure a successful balance between the interests of the operator and those of the surrounding community.

We also offer a range of web-based solutions that are designed to identify the probable cause of odour complaints and potential spurious allegations or malicious behaviour. The Olfasense Ortelium® tool is a good example of successful odour complaint management.

Ortelium

Ortelium ®

Your key to managing odour complaints

Ortelium® simplifies odour complaints management by making it a more transparent process.

The Ortelium® application collects, displays and evaluates the relevant data, communicating it in a meaningful map-based display. By making forecasts and giving feedback to all parties involved in cases of reported odour nuisance, it can enhance community relations and defuse conflict situations.

Ortelium also offers features to facilitate and enrich odour measurement procedures, as well as for odour control. To find our more please visit www.ortelium.com.

Ambient odour monitoring

Ambient odour monitoring

An odour monitoring programme designed just for you

From continuous monitoring to source analysis, the wide variety of ambient air monitoring methods available means there’s plenty of scope for fine-tuning a solution to meet your needs – so that’s exactly what we do.

We’ll find the ambient odour monitoring techniques and devices that are most appropriate in terms of cost, reliability, level of detail and ease of operation.

In this way, we can create an odour monitoring strategy that will give you the best result.
