Odour assessments to help with your projects

An odour refers to the stimuli from a chemical compound that is volatilised in air which may be perceived as either pleasant or unpleasant. The concentration at which an odour is just detectable to a "typical" human nose is referred to as the "threshold" concentration. Standardised methods for measuring and reporting the detectability or concentration of an odour sample have been defined by a European standard (BSEN 13725:2003).

Common sources of odours in the environment modelled by MORET include sewage treatment, slaughter houses / abattoirs & rendering plants, animals, livestock and poultry, spreading of sludge and slurries to land, anaerobic digestion and combined heat and power plants, agricultural nutrient storage. Our experience with, and understanding of, these commercial processes enables MORET to build accurate emissions inventories, leading to reliable and robust odour modelling studies.

MORET is uniquely placed to call upon a wealth of experience at ADAS to provide odour management plans, environmental impact assessments, and planning and permitting applications. Expert Witnesses from both the MORET team and ADAS can provide further support for the permitting and planning process.

Why take an odour impact assessment? 

  • Understand the impact of the facility upon local environmental odours and local residential amenity. 
  • Inform designs - at the project planning stage, proponents, planners and environmental regulators should consider the compatibility of a proposal with current and likely future land uses. 
  • Inform the location choice and design of new activities and sustainable land-use planning around existing activities, ensuring the best environmental outcomes. 
  • Find the most appropriate odour management strategy to suit local conditions and the nature of the emissions generated by the business.

What we provide 

Our odour assessment services include: 

  • Emission inventories.
  • Odour Dispersion Modelling using quality assured Met Office climatologies.
  • The results of the dispersion modelling, presented as modelled odour concentrations at nearby locations (for example, businesses and residences) and footprint maps of the areas of predicted impacts.
  • Comparison of modelled odour concentrations and regulatory guideline values / benchmarks. 
  • Scenario modelling, as required, of proposed abatement / mitigation. 
  • Investigation of odour complaints.
  • Expert comment of the results. 
  • A covering report that meets regulatory guidelines and is valued by permitting and planning authorities. 
  • Expert witness services.
