What Odournet does

Odournet is an independent environmental consultancy specializing in the measurement, assessment, and control of industrial odour emissions. Founded in 1980 and operating as a privately held micro-multinational under Sensenet Holding bv, the group employs approximately 70 specialist staff across offices in the Netherlands (legal HQ), United Kingdom, France, Spain, Brazil, and India, plus a Global Projects Team that deploys standardized portable olfactometry equipment worldwide. Services are delivered to industrial operators and public-sector clients in sectors including waste management, wastewater and sewage, food and beverage production, refining, biofuels, foundries, and livestock, as well as to planning authorities and regulators. The company addresses community complaint mitigation, regulatory compliance (including EN13725 and EN16841), planning applications, and capital investment support.

The core technology stack combines accredited sensory laboratories (olfactometry to EN13725, hedonic tone and character analysis) with a molecular laboratory in Barcelona housing GC-MS/Time-of-Flight (GCMS/TOF) equipment capable of detecting compounds at sub-ppt concentrations, complemented by GC-Olfactometry, GC-IMS, and a Thermal Desorption Unity2 platform. A proprietary compound library built over 30 years and thousands of studies underpins analytical interpretation. The product portfolio includes consulting services, the EnviroSuite software platform for continuous monitoring and complaint management, expert witness services, applied odour training, and the Sensenet sub-brand offering consumer-product sensory testing across perfumery, cosmetics, food, plastics, textiles, automotive, chemicals, and pharmaceuticals.

Revenue is generated almost entirely through project-based professional services engagements and multi-year contracts, with pricing determined per project scope rather than disclosed publicly. Go-to-market is enterprise field sales, supported by direct expert engagement, multilingual web presence, industry conferences, and webinars. Long-tenured client relationships (5-10+ years) with water utilities, environmental consultancies, food producers, and government authorities indicate a high-touch, repeat-engagement model rather than transactional volume sales.

Direct peers

• AIRSENSE Analytics: German manufacturer of PEN3 electronic-nose systems used for odour and gas detection across waste, wastewater, security and food applications — comparable technology vendor in the same odour monitoring market.
• Odotech: Montreal-based odour monitoring specialist offering real-time electronic nose (o-Digit) systems, dispersion modelling (o-Sim) and odour impact assessment services to wastewater, waste and industrial clients — directly comparable to Odournet's measurement-and-modelling stack.
• Olfasense Group: German-headquartered specialist in olfactometry and odour sensor technology; acquired Odournet UK Ltd in May 2020 and is the most direct functional peer, offering EN13725 accredited sensory analysis, electronic nose instrumentation and consultancy to industrial and consumer-goods clients.
• Centro Studi Olfactometria (CSO): Italian olfactometric laboratory and consulting group specializing in EN13725 accredited analysis and industrial odour diagnostics; comparable specialist peer serving Southern European industrial clients.
• Alpha MOS: French sensory and electronic-nose instrument manufacturer (Heracles, e-nose) supplying food, beverage and packaging industries; overlaps with both Odournet's molecular instrumentation and Sensenet's consumer-product sensory testing practices.
• ECOMES (European Centre of Environmental Measurement and Olfactometric Studies): German sensory analysis and olfactometry consultancy serving industrial and municipal clients across Europe with accredited EN13725 testing and odour impact assessment — direct overlap with Odournet's European environmental odour practice.

Broad incumbents

• SGS: Global testing, inspection and certification giant; offers environmental air-quality, emissions and olfactory-related laboratory services as part of a much broader portfolio — competes with Odournet on the testing side but does not focus on odour as a niche.
• RPS Group: UK-based environmental and engineering consultancy with air-quality, EIA and odour assessment capabilities serving waste, water and infrastructure clients — competes on the consulting side where Odournet's industrial odour mandates overlap with broader environmental impact work.
• Eurofins: Largest global laboratory-testing group; provides ambient and emissions testing including some olfactometry-adjacent services through acquired specialty labs — competes at the broader testing-lab level rather than in dedicated odour consulting.
• Bureau Veritas: International TIC firm with environmental testing and industrial air-emissions capabilities; competes for some industrial compliance testing work but lacks Odournet's specialist odour depth.
