Bangladesh adopts smokeless brick making technology
To trim greenhouse gas emissions:
In a bid to trim greenhouse gas emissions to a considerable amount,
Bangladesh has adopted smokeless brick making technology to replace the
over 150-year- old traditional approach.
The new technology has been introduced by the United Nations
Development Program in Bangladesh through a project titled " Improving
Kiln Efficiency in the Brick Making Industry", which will contribute 25
million U.S. dollars for the next five years.
The UNDP launched project will take operational experience from its
pilot Brick Kiln project which started in 2006 and use these results to
implement another 15 demonstration projects over its five year project
period.
With the newly introduced smokeless technologies, UNDP officials said
the industry will operate under higher energy efficiencies, better
energy control capabilities and higher rates of production and
processing.
All of which, they said, could bring about reduced production costs,
improved product quality, lower local pollution and, most importantly,
reduced greenhouse gas emissions.
"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 Bangladesh Country Director, said in a statement which
was issued to say about the project on Sunday.
According to UNDP, brick making is one of the largest sources of
greenhouse gas emissions in Bangladesh estimated to be on the order of
6.0 million tons of CO2 annually.
Such high levels of emissions are a result of the use of outmoded
technologies and substandard fuels such as high sulphur coal, tires and
wood energy in kilns, it said.
The UNDP said estimates indicate that in Bangladesh it takes about 23
tons of coal to produce 100,000 bricks whereas in another country it
takes only 7.8 to 8 tons.
Equally alarming is the use of wood energy in the kilns, it said
adding studies carried out in the 1980's identified brickfields as a
major cause of deforestation in Bangladesh.
The Bangladesh Brick Makers Association, a private body of brickfield
owners, estimates that even today 25 percent of the fuel used in kilns
is still from wood. Growth of the brick industry has been estimated at
5.3 percent over that in the last decade which is likely to continuously
rise over the next decade, it said.
The UNDP Bangladesh country director Priesner said, "The problem here
is that 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."
"The impact of this initiative will be that the communities and
workers health will be protected by not being exposed to such pollution
and land will be freed up in a very densely populated Bangladesh," he
said.
According to the UNDP, the project will also undertake activities to
remove existing policy, institutional, technical, informational and
financial barriers that have inhibited the use of efficient technologies
and practices in the past.
Local experts said the project comes as boon for Bangadesh, world's
largest delta country of 162 million people, which has become more
vulnerable in recent time to climate change related problems like
cyclones, flooding, reduced fresh water availability and sea level rise.
Due to rise in sea level, according to them, the low-lying country
bordering the Bay of Bengal will see at least 19-20 percent of its lands
to go under water by 2050 which is to make over 20 million people
climate change refugees. Xinhua
