It helps to spur advances in clean technology, such as smokestack scrubbers and low-VOC paints

The development of clean technologies has been spurred by the challenge of cleaning the air. This includes the creation of smokestack scrubbers, catalytic converters, and low-VOC paints.

Smokestack scrubbers

Smokestacks are tall stacks that release gases and particles into the atmosphere. Scrubbers are a type of flue gas treatment technology that can be used to remove harmful pollutants from smokestack emissions. They are commonly used in combustion applications, such as coal and oil electric power generation, and come in various types, including wet scrubbers, dry scrubbers, adsorbents, and electrostatic precipitators. These technologies are particularly effective at removing sulphur and nitrogen oxides, toxic organic chemicals, mercury, and particulates from flue gases.

Low-VOC paints

Volatile organic compounds (VOCs) are common indoor air pollutants found in household products such as paints, cleaning products, and personal care products. They can cause adverse health effects, including acute inhalation exposure symptoms like coughing, decreased lung function, and impaired mental focus. They also contribute to outdoor air pollution by interacting with nitrous oxides in the atmosphere to form ozone, a greenhouse gas. Low-VOC paints help reduce these harmful emissions by significantly lowering the amount of VOCs released during and after painting. They are typically water-based and have lower odour than traditional oil-based paints.

The development and utilisation of these clean technologies are crucial steps in reducing pollutant emissions and improving air quality.
