Introductory course on environmental odour management

Traditionally, Industries that produced odour impacts on the surrounding communities had not many tools to tackle this issueFor this reason, these type of industries must pay special attention to the confinement, capture and control of the gases produced. Previously, not much time was dedicated to this subject, but currently, with the demand of citizens for better air quality, the training of technicians who manage the odour emission of an activity is essential.

The aim of this course will be to inform and train on the most important aspects to be taken into account for the proper management of odour emissions in odour emitting industries: how odours are measured, how they are controlled and which are the most relevant regulations and standards to carry out the control of the activity.

What you'll learn

 

  • Get to know the tools available for odour managers.
  • Perform odour evaluations
  • Understand industrial ventilation
  • Understand and present odour results

 

Requirements

 

  • No specific prior knowledge required
  • Familiarity with air pollution and meteorology concepts is helpful

 

Description

 

This course aims to give a general overview of odour management in an industry of this type, describing in a general way the different existing tools and the state of science at present.

Professors

 

Carlos Nietzsche Díaz has more than 18 years of experience in environmental odour management. He has attended most of the international conferences on odour management in the environment and has organised five international conferences being the coordinator of the scientific committee in all cases. He has organised the only specialised courses carried out to date on the CALPUFF dispersion model and odours in 2013 and 2014 in Madrid and Santiago, respectively, with the CALPUFF model development group coordinator Joseph Scire and the New Zealand expert Jennifer Barclay. Carlos Díaz is a member of the Odour and Volatile Emissions Committee of the International Water Association (IWA) and of the Air Quality and Odour Control Committee of the Water Environment Federation (WEF). He is also an authorised representative of AENOR in the Working Group of the European Committee for Standardisation (CEN) which is updating the standard EN 13725, determination of odour concentration by dynamic olfactometry and in the Standard on Electronic Sensors for the measurement of odours (IOMS).

Carlos Díaz is the main editor of the website olores.org, the site dedicated to odour management in the environment and is the president and founding member of the International Environmental Association of Odour Managers (AMIGO) (http://gestoresdelolor.org/).

Cyntia Izquierdo is a Chemical Engineer with extensive experience in odour management. She has carried out the assessment of odour emissions in several industrial plants and has been in charge of the coordination of the III International Conference on odour management in the environment that took place in Bilbao in November 2015 and the IV International Conference on odour and VOC management in the environment that took place in Valladolid in September 2017. Cyntia is a founding member of the International Environmental Association of Odour Managers (AMIGO) and participates as an associate editor in the web olores.org, the portal dedicated to odour management in the environment, as well as having participated in several training sessions on odour emission management.
