Lahore: According to reports, the Punjab Environment Protection Department (EPD) has ordered all brick kiln owners to convert their kilns to zigzag technology within a month.
The progress of the conversion of old technology brick kilns to zigzag technology, as well as other smog-related problems, were discussed at a conference.
Smog was discovered to be a regional phenomenon fueled by: local and cross-border pollution from the burning of agriculture residue, old brick kilns, and steel furnaces/mills in Lahore, Sheikhupura, and Gujranwala; industries with boilers and using sub-standard fuel; vehicular pollution; and the burning of solid waste plastic material and other sub-standard fuel.
Furthermore, the phenomenon is caused by high suspended particulate matter concentrations, precipitation, low temperature, calm wind conditions, and the inversion effect.
Brick kilns, according to EPD Director Nasimur Rehman, are the primary source of air pollution. The EPD Punjab began its fight against brick kiln pollution two decades ago, in partnership with the All Pakistan Brick Kiln Owners Association.
He stated that various options, such as the construction of a vertical shaft brick kiln in Islamabad and an Indian technology brick kiln in Attock, had been tried in the past but that no suitable solution could be found. In Pakistan, the brick industry was once considered an unorganized market, plagued by a slew of environmental and social problems.
The indigenous fixed chimney bull’s trench kilns were used to make more than 90% of the bricks (FCBTK). According to him, representatives from the EPA and the All Pakistan Brick Kilns Association visited Nepal to examine the activity of zigzag brick kilns.
This zigzag approach was found to be quite similar to the current bull trench kilns by the association. As a result, they built one of these kilns in Lahore using their own funds. The kiln was tested by the Punjab EPA lab and found to be much superior to the old technology kiln.
Experts from the International Centre for Integrated Mountain Development have confirmed a reduction in emissions of more than 70%, a 30% reduction in fuel consumption, and a baking time of less than half that of the old technology kiln.
The zigzag kiln produces four to five times faster than the bull trench.
He claimed that the technology conversion would be accelerated and that blowers had been built in 7,986 brick kilns in Punjab.
