Geo mapping of brick kilns


The Punjab government has started geo-mapping of brick kilns across the province. They took this step to ascertain installation of eco-friendly zig zag technology.

As per the report, the total number of brick kilns in Rawalpindi district has increased to 215.However,  a total of 6,940 of them are present across Punjab. Following the Geo-mapping process, the Punjab Government has issued red notices to the owners to install kilns having the zigzag technology by January 31. Before Geo-mapping, the number of brick kilns in Rawalpindi was 200. However, some 215 kilns have been identified by the officials in the Geo-mapping.

Environment Protection Department officials said that installation of zig-zag technology in all smoke-emitting brick kilns will be completed by the authorities, by December 31. He added that a massive crackdown against brick kilns without Eco-friendly technology will be launched January 4. Consequently, all of such setups would be sealed.


The bricks are placed in a zig-zag pattern. The zig-zag pattern allows to efficiently move the air for heating purposes. The zig-zag setting of bricks and continuous feeding of small quantities of coal improves fuel efficiency. As a result, the emitted smoke from the kilns employing zig-zag technology is white colored and with significant low air pollution levels. It reduces coal consumption by 20 per cent. Likewise, carbon emissions by 40-60%. In addition, it produces more A-grade bricks, and brick production can be enhanced as well. 

 The first brick-kiln on zig-zag technology was successfully constructed by Haji Islam.  He is an active member of the All Pakistan Brick Kiln Association.

The brick-kiln association fully supports zig-zag technology. As it makes an excellent business case. The return on investment can be achieved within a short period.

One of the owners of the brick kilns says, Owing to the smog crisis in winters, the Punjab government does not allow traditional brick kilns from working in September and October every year. Because of this, Parvez says, “until 2018, I had to shut my traditional brick-kiln too. Hence, resulting in the loss of millions of rupees. Not only could I not do any business during these months. But when I would restart the kiln in November, the preheating of the kiln used to cost me about one million rupees.”

“That trouble is over now, as my brick-kiln on zig-zag technology runs throughout the year,” he shares.
