100% Zig-Zag Green Brick Kiln Transformation Achieved

In a landmark environmental achievement, EPA Punjab has completed the 100% transformation of all registered brick kilns to the zig-zag firing technology. This transition, driven through a combination of regulatory enforcement, financial incentives, and technical training, has resulted in a dramatic reduction of particulate matter (PM2.5 and PM10) emissions from the brick manufacturing sector — one of Punjab's biggest contributors to winter smog.

Impact on Air Quality

Zig-zag kilns burn fuel more efficiently, reducing coal consumption by 20–25% and cutting black smoke emissions by up to 70% compared to conventional Fixed Chimney Bull's Trench Kilns (FCBTKs). The transformation has been verified through EPA Punjab's ambient air quality monitoring network and real-time CEMS data from major clusters.
