Where is the odour generated?
Map point, area and fugitive sources. Record process stage, exposed surface, airflow, temperature, disturbance events and operating cycle.
Industrial odour knowledge and application
Understand the odour. Control the source.
A technical research hub for environmental consultants, operators, engineers and project teams dealing with odour in waste, wastewater, remediation, bitumen, manufacturing and other industrial settings.
Odour science
Move beyond masking and product-first decisions.
Industrial odour management requires a clear distinction between the emission source, the compounds present, how people perceive them and how performance will be verified.
What compounds may be present?
Reduced sulphur compounds, amines, aldehydes, organic acids and hydrocarbon vapours behave differently. Instrumental analysis can support source identification and treatment selection.
How is the odour experienced?
Intensity alone is not enough. Character, hedonic tone, frequency, duration, familiarity and receptor sensitivity shape annoyance.
Industrial applications
Technical pathways by site type.

Assessment framework
Assess. Design. Apply. Verify.
Use this sequence before setting a dilution, choosing equipment or making a performance claim. Chemical treatment may be a primary intervention in some applications, and a secondary or polishing step in others.
Do not rely on fragrance response, a single walkover or complaint counts alone. Combine observations with process conditions, weather, operational records and suitable testing.
1
Define the objectiveComplaint reduction, boundary control, worker amenity, process improvement or short-term control during high-risk works.
2
Build the source modelDocument source category, likely compounds, release mechanism, operating pattern and pathway to receptors.
3
Choose measurement methodsField assessment, dynamic olfactometry, GC-MS, targeted gas sensing, meteorology and process indicators as appropriate.
4
Select treatment and deliveryDirect dosing, surface spray, perimeter mist, local fogging, scrubber support or compatible process additive.
5
Run a controlled trialKeep application volume and conditions consistent. Use a control, predefined observations and clear acceptance criteria.
6
Review and optimiseAdjust chemistry, contact opportunity, droplet size, equipment position and dosing against recorded results.
Measurement matrix
Select evidence that fits the question.
| Method | Best used for | What it does not answer alone | Typical decision supported |
|---|---|---|---|
| Structured field assessment | Character, intensity, frequency, location and operational context | Exact compound concentration or source contribution | Hotspot mapping and trial observation plan |
| Dynamic olfactometry | Measured odour concentration using a trained panel and defined method | Identity of individual chemical compounds | Baseline, comparative performance and modelling input |
| GC-MS | Identifying and quantifying suitable volatile compounds | Human response to the complete mixture | Source profiling and chemistry-specific investigation |
| Targeted sensors | Continuous or rapid indication for selected gases | The full odour mixture or all nuisance effects | Process alarms, trends and operational correlation |
| Meteorology and complaints | Timing, transport pathway and receptor pattern | Proof of source or treatment efficacy without corroboration | Incident review, deployment timing and investigation priorities |
Preliminary selector
Build a practical starting pathway.
This tool gives a screening recommendation only. Final selection must consider the current product SDS/TDS, process compatibility, site controls and trial data.
Suggested starting pathway
Select the site conditions, then generate a screening pathway.
