Bangladesh Adopts Green Brick Kiln Technology
Vamban News 5th April 2010 Dhaka,
– In an effort to reduce carbon emission, Bangladesh is looking at smokeless brick making technology to replace the over 150-year-old traditional method in the country. The new technology has been introduced by the UNDP as part of its project ‘Improving Kiln Efficiency in the Brick Making Industry’.
The UNDP, which started its pilot project in 2006, will contribute $25 million in the next five years for 15 new projects in the country. ‘The innovative technology that is being used to replace the existing 150-year-old system will simply make the brick making industry so efficient that when this is replicated across Bangladesh we will have huge benefits for both the people and the global environment,’ Stefan Priesner, UNDP’s Country Director, said Sunday. UNDP said that the new system could reduce production costs, improve product quality, lower local pollution and, most importantly, reduce greenhouse gas emissions, Xinhua reported. According to UNDP, brick making is one of the largest sources of greenhouse gas emissions in Bangladesh which produces around 6.0 million tonnes of carbon dioxide annually.
High carbon emission level is caused by the outdated technology and substandard fuels such as high sulphur coal, tires and wood energy in kilns, it said, adding that in Bangladesh it takes about 23 tonnes of coal to produce 100,000 bricks whereas in other country it takes only 7.8 to 8 tonnes.
‘The traditional technologies of manufacturing bricks are heavily polluting the environment and in light of the economic growth in Bangladesh there is a huge pressure to manufacture more and more bricks,’ Priesner added.
