  • Predicted impacts assessments

Approval and permits

Helping businesses comply to environmental regulations.
  • Assistance in applying for municipal and governmental regulatory permits
  • Environmental compliance (e.g. MELCCFP-Article 197)
  • Environmental auditing
  • Emission inventory reporting (e.g. NPRI, IQEA, Ontario regulation 351/19)

Environmental management planning

  • Aerated surface source sampling
  • Flowrate measurements and QA/QC of sample handling and transportation
  • Olfactometric analyses and reporting

Tailored solutions

Implementing customised strategies for odour and air quality management.
  • Tailored solutions to manage air quality and odour issues
  • Innovative control technologies recommendations
  • Public awareness initiatives

Research and insights

Guiding our clients’ decision-making through our research and insights.
  • Analysing the sources of air quality problems and odour nuisances
  • Advancing the science on odours and olfactometry

ODOLAB: mobile olfactometry laboratory

Odolab is the only mobile olfactometry laboratory in Quebec, providing advanced sensory odour analysis to help businesses optimise and control air emissions.

With our mobile laboratory, we can conduct on-site assessments, significantly reducing the time between sampling and analysis. This rapid response enables businesses to better manage air quality and environmental impact.

 

Odolab provides a wide range of services, including :

  • Odour concentration analysis (ouE/m³) – EN 13725
  • Gas Chromatography-Mass Spectrometry (GC-MS)
  • Sensory acuity certification of human assessors – EN 13725
