How do kilns pollute?

Kilns can pollute the environment primarily through the emission of harmful gases and particulate matter during the firing process. High temperatures can lead to the release of volatile organic compounds (VOCs) and nitrogen oxides, contributing to air pollution and smog formation. Additionally, if fueled by fossil fuels, kilns release carbon dioxide and other greenhouse gases, exacerbating climate change. Proper emission controls and using cleaner energy sources can help mitigate these impacts.
