Technical and Economical Assessment of Vertical Shaft Brick Kiln

Infrastructure development, particularly the housing problem, is one of the serious issues in developing countries like Nepal. The development of housing complexes is related to various financial and environmental implications. One of the basic parameters involved in the infrastructure development pertinent to Kathmandu valley is the use of alternative materials to masonry unit, particularly bricks. Vertical Shaft Brick Kiln (VSBK) should be adopted and diffused in Nepal because it is high time for energy-efficient and environmentally friendly technologies. Various studies and monitoring has shown that (VSBK) Vertical Shaft Brick Kiln technology is an improved brick making process. The major advantage of VSBK technology is its energy efficiency and environmental friendliness. VSBK consumes 30 to 40% less energy and reduces environmental pollution by 80 to 90% in comparison to FCBTK technology. The Strength of this brick is also higher than FCBTK brick. Further VSBK provides an improved working environment (Reduced Occupational Health Hazards) to the workers.
