Air pollution: what will happen after the lock downs from the coronavirus?

Reduction of industrial emissions

The coronavirus pandemic revealed a huge drop in air pollution. Thanks to the lock down many countries choose to put in place since January 2020 (starting with China), the industrial emissions have seen a drastic drop worldwide.

The Satellites from the European Space Agency took pictures showing a lower level of nitrogen dioxide (NO2) above cities and industrial clusters in Asia and Europe in 2020. They compared those images with previous images taken during the same time frame in 2019 to see the difference in NO2 level. And the difference is clearly visible, with a drop of emissions above industrial clusters and cities.

This is the opportunity for a cleaner world by maintain low air pollution from industrial emissions for example. But with the restart of the economies worldwide, how can industrial control their pollution and participate to the reduction of emissions?

How to keep a cleaner air by continuing to lower air pollution after the end of the lock downs?

Air pollution and health

Air pollution contributed to 5 million deaths in 2017 caused by stroke, heart attack, diabetes, lung cancer and chronic lung disease. It is the 5th leading risk factor for mortality worldwide (Source:, inflaming and lowering immunity.  According to the non-profit European Public Health Alliance (EPHA), air pollution exacerbate or cause respiratory illnesses like asthma and pulmonary diseases.

Therefore, air pollution has been one of the major problem to tackle with new environmental measures by reducing the emissions from households and industries.

  • Nitrogen dioxide (NO2) emissions are produced by power plants and other industrial processes, but also car engines.
  • Carbon emissions are produced by greenhouse gas and other pollutant from industrial sectors.

Since the beginning of 2020 with the outbreak of the coronavirus and lock downs imposed in different countries, there has been a temporary fall of pollutant emissions (up to 40%).

This drop participated to improve air quality. As an example, people in India started to see the Himalayas from Punjab, more than 100 miles away, for the first time in 30 years due to the air pollution decreasing in the surroundings thanks to the lock down of the country (Source: CNN Travel).

Already this reduction in air pollution has seen positive effect for the environment with a cleaner breathable air. The current situation became the largest-scale test to see how to achieve a low-carbon economy.

How clean is the air you are breathing?

Industrial emissions: one of the causes of air pollution worldwide

Even if in Europe the release of pollutants by industries have decreased during the last decade, industrial pollution is still a significant source of pollutant (Source: European Environment Agency, Sept 2019).

Initiatives, like increased environmental regulations, installation of improved pollutant abatement technology, improvements in energy efficiency, reduction of fuel fossil energy, etc., participate to the decrease in pollutant releases.

As manufacturers, implementing better pollutant abatement technologies has a tremendous impact on controlling your pollutant emissions.

Dust pollution, gas pollution, odor pollution, there are many types of airborne pollution that a factory can emit depending on its production.

With efficient pollutant abatement technologies! How can IKEUCHI help?

As the Fog Engineers, we offer pollution control solutions based on our atomizing technology.

In a previous article, we’ve introduced the principle of suppressing the floating airborne contaminants with fog (click here to read more). Depending on the pollutant to clean from the air, the size of the water droplet sprayed is important.

Therefore, we offer solutions that are suitable for each Air Quality Control Systems (AQCS) process with tailored nozzle design and materials:

  • Dust suppression for environment and health protection:


  • Exhaust gas cooling and cleaning:


  • NOx reduction solution for SNCR and SCR systems:


  • Flue-gas desulfurization (FGD) for SOx reduction:


  • Clog resistant cleaning nozzles for Wet Electrostatic dust Precipitator:

As each factory has its specific layout and needs, our Sales engineers analyze the problem to offer the most suitable solution.

From dust suppression to gas cleaning, we will find the best solution for your request.

Don’t hesitate to contact us!
