Sustainability Factsheet #02

The Department of Environmental Affairs has set limits for the air pollutants that may be released from clamp kilns.

As the oldest and (still) most utilized firing technology in the country’s formal and informal brick making sector, local and international researchers have looked for ways of optimizing the design of clamp kilns in order to reduce emissions of sulphur dioxides (SOx), nitrogen oxides (NOx) and particulate matter released during the firing of clay bricks.
