Conventional brick kilns’ Bull’s Trench Kiln (BTK)”in Pakistan’s Punjab province are a significant source of greenhouse gas emissions and harmful particulates which exacerbate climate change and deteriorate ambient air quality, respectively.
The International Centre for Integrated Mountain Development (ICIMOD) has recently introduced a new kiln technology “Induced Draft Zigzag Kiln (IDZK)” in Nepal which is more energy efficient than conventional kilns. ICIMOD statistics suggest that IDZKs produce 25 percent more high-quality bricks, use 30 percent less fuel, and generate 70 percent less emissions compared to BTKs.
This study was funded by the IGC (2018).
