Odour control


Taking a proactive approach to odour control will earn you a reputation as an environmentally responsible business which is respectful of its community. Desotec is ready to partner with you, offering a rapid delivery of sustainable mobile filtration solutions so that your business operations continue smoothly.

Why should you treat odours?

It can be hard to pinpoint the source of odours, and emissions measurement is complex and somewhat subjective. Therefore, the need to treat odours often arises only when complaints are made.

With increasing urbanisation and lower tolerance for odour nuisance, some long-established sites are facing complaints for the first time. These might arise even when a site meets environmental emissions limits.

Desotec’s mobile filtration services allow you to treat odours promptly, pre-empting action required by environmental authorities and avoiding costly downtime. You’ll also maintain your positive image in the media and community as well as creating a more welcoming facility for site workers and visitors.

What are the industrial sources of odours?

Many industrial sectors inevitably produce odours. Yet, highly effective treatments such as  Desotec’s mobile filtration solutions are available.

Naturally, the food and feed industries are rich in smells. There is low tolerance for certain odours, such as pet food, slaughterhouses, and meat & fish processing. Others, such as coffee roasting, may be pleasant, but only at lower concentrations.

Sulfur smells from waste management and wastewater treatment may also be reduced by Desotec’s filters so they don’t disturb those living nearby.

While there is generally a higher tolerance for agricultural odours, it’s important to treat fertiliser smells and those emanating from biogas plants.

Other applications where industrial odour control makes all the difference include those related to the manufacture or handling of asphalt and bitumen, fragrances, polyester and composites, paints and coatings.

Which molecules require industrial odour control?

Odorous molecules may be volatile organic compounds (VOCs) or inorganic chemicals, including:

  • Amine smells from fish processing.
  • Phenol and benzene odours from petroleum.
  • Acrylate and styrene odours from plastics and composites.
  • Hydrogen sulfide (H₂S) and other sulfur smells from bitumen and biogas.
  • Ammonia (NH₃) from fertilisers.
  • Dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), aromatic hydrocarbons, H₂S, and NH₃ from sludge, sewage and wastewater treatment.

With Desotec’s activated carbon filters, manufacturers are successfully treating these odours and many others.

Local industries are at the heart of their communities, providing them with job opportunities and economic benefits. Desotec mobile filtration services let each industrial installation build good relations with neighbours by keeping the air fresh and clean.

Helping you comply

As odour complaints rise, regulations are becoming stricter. Desotec has both the know-how and the technology to enable your firm to comply with upcoming legislations.

At the EU level, the Industrial Emissions Directive (IED) is the main regulation that governs odour emissions.

Country-specific legislation includes TA Luft in Germany, which has been updated to include nationwide regulations around odour. Other countries and regions have similar legislations.

Environmental authorities set the terms of site operating licences, which may include odour emissions limits. If your company is facing investigations by these authorities, we can promptly deliver effective solutions.

How we help you

Desotec sustainable mobile filtration solutions

If your firm faces odour issues, Desotec’s full-service mobile activated carbon filters provide answers.

We install filter set-ups using standard activated carbon for VOCs or impregnated activated carbon for inorganic compounds. Filters work alone or in combination with other technologies. In urgent situations, our mobile filters will be operational in no time.

We transport filtration waste in closed units away from your site. All molecules are destroyed and, where possible, carbon is reactivated, giving you a circular solution that is both efficient and green. Where reactivation is impossible, waste is treated safely. Our R&D team is continually seeking new treatment solutions to further boost sustainability.

DESOTEC has supported us for the engineering and supply of our process air purification, which allows us to capture odours and avoid emission to our neighbours.
