Odour neutralisation in industry - 6 options for companies
Are your neighbours, politicians or the local press complaining about odour nuisance from your business? Then you need to take action to comply with the Odour Immission Directive (GIRL) as quickly as possible and safeguard the existence of your business. Bad odours can generally be eliminated mechanically, chemically or biologically. Industrial companies such as mixing plants, sorting plants, warehouses, food producers or plastics processors can fall back on the following 7 options for odour neutralisation:
6 Ways to Neutralize Industrial Odors
1. GreenAirPlus systems
GreenAirSystems has invented the first odor neutralizing device that doesn't use expensive or toxic waste at all. The world's only odor elimination equipment relies on a natural mixture of denatured sugar, water and air pressure to literally make your unpleasant odors disappear into thin air. This novel and officially tested method
- can be implemented in your company within only 12 weeks,
- costs a fraction of the cost of conventional methods for odour control and
- is based on natural active ingredients without producing expensive hazardous waste.

The exhaust air is also biologically cleaned in a biofilter. It is a so-called fixed-bed reactor that separates gaseous or dissolved substances. The unwanted odorous substances are decomposed by microorganisms - such as bacteria, fungi or yeasts - into carbon dioxide and water with the help of oxygen. Biofilters are available, for example, in the form of containers, towers or surfaces. The filter bed on which the microorganisms live can consist of peat, compost, bark, plant fibres or paper granulate. Biofilters must be permanently moistened and operated with fans and can only be used with biodegradable, non-toxic substances.
3. activated carbon filter
Filters with activated carbon absorb unwanted substances such as dust, heavy metals, ozone or chlorine and accumulate them in the carbon mass. These are oxidized by the filtration and adsorption and thus consumed. Activated carbon filters are found not only in industrial filtration of odours but also in aquariums, cigarette filters, cars, extractor hoods or hard drives. The mass of the activated carbon is reduced by the adsorption of the pollutants and must be refilled or replaced regularly.
Bioscrubbers have been used since the 1930s, mainly in livestock farming, to clean exhaust air. They usually consist of an absorber, a regenerating reactor and a settling tank made of concrete, steel or plastic. The reactors are used for biological purification of exhaust air and exhaust gases. Exhaust air scrubbers are also called chemical scrubbers and can be used in one, two or three stages. They can wash bases such as ammonia, acids such as sulphuric acid, hydrochloric or hydrofluoric acid, alkaline soluble substances and also organic as well as odorous substances from the exhaust air. Air scrubbers clean the air by sucking in polluted air, filtering it through water, and expelling clean air. Coarse particles such as dust, pollen, smoke or odour molecules are bound in the water, while the clean air flows back outside moistened.
5. ozone filter
An ozone or fine dust filter cleans the air of harmful substances such as ozone, benzene, toluene and fine dust, but also of unpleasant odours and volatile carbon compounds (VOC). The filter consists of electrostatically charged material, often with a layer of activated carbon, and is used primarily in the transport and printing industries to clean exhaust air.
6. UV filter
UV technology has been used for several years, e.g. to eliminate odours in commercial kitchens. UV photons break down unwanted compounds in the ultraviolet tubes by photosplitting and decompose them into harmless components. To do this, the air must be highly pre-filtered and free of any particles. The UV radiation kills bacteria and germs and also serves as a disinfectant. UV filters are comparatively expensive and not very environmentally friendly and are rarely used in industry.
GreenAirPlus: The mist that destroys odours without waste
GreenAirPlus is an innovative odour eliminator for industry, whose technical centre is no bigger than a refrigerator and is sprayed via nozzles directly at the odour-generating points in your plant. The fine, dry mist serves as a catalyst and transforms the double bonds of an odour molecule into an odour-neutral carbon chain.
