Air Quality & Treatment
Improved air quality carries significant benefits for the environment and human health.
Air pollutions effect on human health
Industrial activities, transportation, power plants and incineration of waste emit harmful substances into the air. The World Health Organisation (WHO) estimates that air pollution causes about 3.3 million premature deaths worldwide per year. Reducing the level of one particular type of air pollutant (particulate matter) could decrease mortality in polluted cities by as much as 15% every year.
Improving air quality everywhere - for everyone
SO2 and NOx found in smoke or exhaust from power and incineration plants can be cleaned by using catalysts and scrubbers. CO2 emissions can be reduced through Carbon Capture and Storage (CCS), where CO2 is physically removed from flue and waste gases. The CO2 can then be compressed to liquid form and stored in suitable underground locations. In Denmark, the geological conditions for storing CO2 are present in many areas.
Denmark has successfully reduced atmospheric pollution in most areas to less than one fifth of the levels during the late 70ies. With more than 200 high-tech companies delivering clean air solutions for shipping, power and incineration plants, vehicles and indoor environment, Denmark holds the knowledge necessary to make similar improvements in other countries.
- Quick fact: While particle pollution itself will sometimes form aerosols and smog and thus contribute to local cooling, the larger effect of pollution, in the sense of greenhouse gas emissions, is global warming.
- Quick fact: Air pollution has also caused a thinning of the protective ozone layer allowing more of the sun's ultraviolet light to pass through to the Earth's surface and cause damage to humans, animals and plants.
- Quick fact: Cleaned flue gas often contains fewer particles than the surrounding air.
