    Bangladesh: Around 92% of the kilns for manufacturing bricks in Bangladesh are of the severely polluting, energy intensive Fixed Chimney Kiln (FCK) type (Fig. 5a). The other types such as Zigzag Kiln, Hybrid Hoffmann Kiln (HHK), Vertical Shaft Kiln (VSBK) are less polluting but capital intensive, hence only comprise the remaining 8%.

    It is also difficult to enforce regulations on these kilns which can literally be moved from place to place. The zigzag kiln, introduced in the 1970s by the Roorkeebased Central Building Research Institute, is an improvement over the FCBTK. It requires air to travel through a zigzag path, which makes it more efficient and less polluting.

    Most of the kilns in Bangladesh are fixed chimney (FCK) type, which are somewhat old technology and sources of pounding pollutions. Recently the Department of Environment (DoE) of the Bangladesh Government has directed brickfield owners to switch to comparatively better environment friendly technologies like Zigzag, Hybrid Hoffman (HHK) and Vertical Shaft (VSK) kilns.
