Co-Benefits of Financing Vertical Shaft Brick
Kilns in Nepal

Presentation Summary
  • Air Quality Brick Kilns
  • Vertical Shaft Brick Kilns
  • AQ Benefits of VSBK
  • Potential CDM Benefits

3
Air Quality Issues in Nepal
  • Indoor AQ is a major concern
  • Biomass supplies 85 of energy needs
  • Rate of urbanization is very high
  • Air quality is a major problem in Kathmandu Valley

4
Air Quality Brick Kilns
  • 166 brick kilns in Kathmandu Valley
  • Brick demand is 1.1 4 billion/yr growing at 11
    /yr
  • In 1993, brick kilns contributed 27 of PM10
  • Till 2003, most brick kilns utilized very
    polluting Moving Chimney Bulls Trench Technology
  • Since then new cleaner technologies have been
    introduced
  • Brick Kilns operate in winter and dry season,
    when air pollution is also at its peak

VSBK Technology
9
VSBK Technology
  • Initially developed in China
  • First introduced in Nepal in 1991 Reintroduced
    2003
  • Energy Efficient and very low emission
  • Effective combustion
  • Arrangement of bricks act as a dust strainer
  • Energy conservation due to natural up drought
  • Vertical kiln with stationary fire and moving
    brick
  • Operates throughout the year Bulls Trench Kilns
  • Production capacity about 6,500 bricks per day
    per shaft

CDM Potential in Nepal
  • Nepal has ratified the Kyoto Protocol
  • Limited potential for large scale projects
  • Some potential in promoting renewable energy
    energy efficiency
  • Biogas project has been registered
  • Projects being considered include solar
    lighting, improved cook stoves, solid waste
    management, electric vehicles
  • In the industrial sector, brick industry presents
    a major opportunity for CDM and AQ benefits

12
What Makes VSBK a CDM Project
  • New technology with low adaptation rate
  • 3 VSBK compared to more than 100 Fixed Chimney
  • 40-50 energy efficient than Fixed Chimney
  • VSBK 0.069 kg/brick FC 0.14 kg/brick
  • Brick production is energy intensive cost of
    coal is about 40 of total operating cost
  • Higher capital cost and relatively lower return
    on investment than fixed chimney
  • Pay back period - FC 1yr 2 mo. VSBK 2 yr. 2
    mo.
  • More technical know-how required
  • High local environmental benefits

13
Emission from Various Types of Brick Kilns
Compared to Moving Chimney BTK, VSBK Emission is
less by a factor of 14 Compared to Fixed Chimney,
VSBK emission is less by a factor of 3

Emission Reduction through VSBK

15
Main barriers for Promotion of VSBK
  • Investment Barrier
  • Initial investment FC US64368 VSBK (six
    shafts) US 133,200
  • Technological Barrier
  • Barrier of prevailing practice

16
VSBK CDM Project Activity
  • 72 shafts in KTM valley in five years
  • 10 Years crediting period, starting 2006
  • Baseline is fixed chimney
  • Baseline emissions 28,241 tCO2e/yr
  • Project emissions 13,891 tCO2e/yr
  • 14,351 tons of CO2e saved per year
  • At 7/ton 100,457/year
  • Distribution of revenue 40 to entrepreneur 40
    to VSBK program 20 for social activities
  • Currently, PDD is being revised (prepared by
    Winrock International, Nepal under ADB funded
    PREGA project)

17
CO2 Reduction
  • Emission from Fixed Chimney
  • To produce 8.1 million bricks/yr (actual
    production from FC)
  • Coal use 1,133 tons
  • Total CO2 emission 2,792 ton (CO2
    emission/brick 0.345 kg/brick)
  • Emission from VSBK
  • To produce 8.1 million bricks/yr (to produce same
    as fixed chimney)
  • Coal use 557 tons
  • Total CO2 emission 1,373 tons (CO2
    emission/brick 0.175 kg/brick)
  • Emission reduction from 4-shaft VSBK (brick
    production 4.55 million bricks/yr)
  • CO2 emission reduction/brick 0.175 kg/brick
  • Total CO2 emission reduction 797 ton/year

18
Challenges
  • Financial
  • High project development transaction cost for
    CDM projects
  • Fixed chimney is financially very attractive
  • Technical
  • CDM is complicated and understanding of CDM is
    very limited
  • Difficult to verify emission saving
  • Institutional
  • Capacity to develop and process process CDM
    projects
  • Bringing together several kiln owners can be
    difficult

19
Conclusion
  • VSBK can significantly reduce air pollution in
    Kathmandu Valley
  • Existing investment and technological barrier has
    led to very low adoption rate of this clean brick
    kiln technology
  • Low energy consumption per brick in VSBK provides
    opportunity for CDM
  • Promotion of VSBK in Kathmandu valley can provide
    a good example for co-benefit of local air
    pollution and global GHG emission
