Odour prognoses for preventing unpleasant odours
Smells can be enormous burden on us, if they are perceived as unpleasant, and especially if they are continually produced where people live.
The demands of residents for the quality of their living environment are on the rise. As a result, the need for well-founded conclusions on odours problems is growing, starting with the land use planning and authorisations as well as court cases. Odour estimates provide important bases for decision-making.
For a forecast, odour emissions are projected from odour-relevant system data or agricultural companies (operating times, source levels, number of animals, quantity of exhaust air, etc.) published values and odour-specific data from a variety of measurements of odour emissions taken by our experts. Together with site-specific meteorological data, we conduct a propagation calculation to calculate the odour emissions in the system's environment. These odour emissions tell us how often a system is smelled in neighbouring residential homes. This frequency forms the basis of the assessment as to whether the odours could present a significant nuisance level.
What sets us apart?
We are a recognised measurement centre in accordance with Sections 26 and 28 of the Federal Emissions Protection Act and active for about 30 years in the field of odour investigation.
- We have a quality management system. It is certified according to DIN EN ISO 9001:2000 and DIN EN 17025.
- We work with national standard committees for quality assurance and development of odour measurements and projections (VDI 3782, Bl. 13 "ensuring the quality of pollution forecasts", VDI 3884, German elaboration of DIN EN 13725, VDI 3880, "olfactometric sampling")).
- We engage officially certified and attested experts for odour analysis.
- We develop all devices for olfactometric sampling in-house (including long-term samplers, sampling hoods and gas-jet pumps for dynamic pre-dilution).
- The following publications can be found at this link:
- Biomass, biogas
- Against odours
What services do we offer?
We measure and analyse odours and develop solutions for operators and affected parties. For this, we can draw on the entire range of measurement and projection technology:
- Odour emission projections based on existing measured values from investigations of odour (olfactometry)
- Odour emission projections with the help of proliferation calculations.
- Assessment of odour pollution based on legal requirements, the specifications of approval authorities and the current legal practice
- Performing grid and plume surveys
Examples of odour-relevant plants on our reference lists

According to which statutory regulations do we work?
There is such a broad range of tasks in odour assessments that the solutions cannot be standardised. The procedure in such investigations is governed by the Federal Emissions Protection Act (BImSchG), odour pollution directives (GIRL), and national and European standards (DIN EN 13725 (olfactometry), VDI 3940 (inspections)) and other specific standards (e.g. VDI manual on air cleanliness).
