Co-Benefits of Financing Vertical Shaft Brick Kilns in Nepal Bhushan Tuladhar, Environment & Public Health Organization (ENPHO), Nepal Jeeven Acharya & Anil Raut Winrock International Nepal
Presentation Summary • Air Quality & Brick Kilns • Vertical Shaft Brick Kilns • AQ Benefits of VSBK • Potential CDM Benefits
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
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 • 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 Bull’s 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
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
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 Source: Institute of Environmental Management, May 2005
Main barriers for Promotion of VSBK • Investment Barrier • Initial investment: FC: US$64368; VSBK (six shafts): US$ 133,200 • Technological Barrier • Barrier of prevailing practice
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)
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
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
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
