Purenviro TOM

Purenviro TOM is short for Total Odor Management. All the tools have been gathered and integrated in this system with one aim, to manage odor emissions efficiently. It is an effective systems which uses all available information, optimally, cost effective and time-effective. With the TOM system, one achieves greater results with lesser effort.


Purenviro TOM integrates automatic dispersion modeling with complaint management, communication, incident tracking and plant optimization.


For the most part, TOM is automatic. It registers complaints and does automatic tracking. Weather data is logged automatically as well. TOM publishes information and reports automatically. All the tools are put together to reduce the amount of work and to create better results.

  • Reduce costs for complaint handling
  • Simplify troubleshooting
  • Save time by using automatic registration and reporting
  • Always updated dispersion image
  • Conduct neighbor surveys based on TA3019 and VDI 3883
  • Reduce nuisance by considering emission forecasting
  • Archives and reports are always up to date. Maintain full overview

Purenviro TOM is flexible and scalable, and finds usage in a number of different industries. The following are examples:

Neighbor survey nearby a wasteplant

Diffuse emissions from wasteplants is often difficult to quantify. Neighbor survey is a very good method of quantifying the odor emission. TOM conducts neighbor surveys and reports automatically.

Emission from wastewater treatment plant

Many large wastewater treatment plants have open impoundments and tanks which causes diffuse emissions. Together with gas-sensors, Purenviro TOM is used to measure and follow up emission from several of Europe’s largest wastewater treatment plants.

Optimization and automatic reports

Production of fish feed, fish oil and fish proteins often result in odor complaints and nuisance. Purenviro TOM is used in these industries to monitor the abatement equipment and to generate automatic reports.

Emission from process industry

Emissions from process industry are often easy to quantify, but in some cases, it can be other companies with emission in the same area. Is it your company who causes the complaints? Purenviro TOM can document whether it is your company or another company who causes the complaints.

Monitor odor from Biogas

Biogas plants emits a lot of odor. Purenviro TOM is used on biogas plants to manage emissions and report automatically to the authorities. Automatic neighbor surveys are used to quantify the nuisance.

Updated status

Purenviro TOM always displays an updated image of the gas/odor emission. Additionally, you can browse from historical data.


Purenviro TOM runs dispersion modeling based on the latest, updated weather forecast, and indicates when it is high and low risk for complaints

Map of complaints

Purenviro TOM displays all the registered complaints on a map. The color indicates whether the complaint is justified. You can filter different types of complaints, and display different time periods.


Create a log on events, and learn what causes problems. Publish messages on the web or Facebook by one single click.

Complaint management

Purenviro TOM includes an effective complaints management system. Display how the emission was at the relevant time period, and compare with registered incidents. You can even browse and check how the level of the emission was just before and after the recorded time period.
