Odour Measurement and Control

Benbow Environmental can measure and determine odour dilution units (ODU), or odour concentration in odour units (OU), from olfactometry laboratory analysis and real-time field measurement devices such as the “Nasal Ranger”. From these measurements, specific odour emission rates can be calculated.

Odour releases from existing and proposed operations can also be assessed using industry recognised modelling techniques to determine odour impacts, and thus allow the means to plan for control measures if need be.

Some examples of industries and clients Benbow Environmental have worked with include:

  • Metal Processing and Fabrication – Alcoa & Ingal Civil Products;
  • Building Materials – Readymix, CSR Building materials;
  • General Manufacturing – Aeropack Australia, Nestle;
  • Waste Industry - WSN Environmental, Wanless Waste Corp, Visy Recycling, Cleanaway, Stericorp;
  • Produce Industry - Poultry farms, Piggery farms, poultry processing facilities;
  • Energy – Smithfield cogeneration plant, Huntley (NZ) cogeneration plant; and
  • Sustainable industries – EDL Appin and Tower Methane conversion plants, Sydney gas sites.
