Thermal oxidisers are air pollution abatement options for hazardous air pollutants (HAPs), volatile organic compounds (VOCs), and odorous emissions.

Most effective is the switch to clean power sources such as wind power, solar power, hydro power which do not cause air pollution.

A very effective means to reduce air pollution is the transition to renewable energy.
