In a country like United States for example, they also produced over 100 million tons of coal fly ash every year and facing almost the similar problem in handling the massive amount of fly ash waste produced. Thus it is very important for them to find solution for this problem. Now days around 43% of fly ash waste in the United 2
States is currently recycled, the major used by far being the replacement of Portland cement (cement manufactured from chalk and clay which hardens under water and when hard resembles Portland stone in color). Due to the massive amount of waste increasing from year to year it is very important to reuse and utilized the waste. Today, more than 16,000 fly ash brick plants are operating in India starting from just 100 plants in year 2000. Although the number of plants are increasing but still there is a market potential for it as the fly ash waste in India is not 100 per cent utilize. For the production record, fly ash bricks account nearly one-sixth of India’s annual bricks production. Considering the main idea is to overcome the problem of disposal of fly ash, reducing the number of land required as well as the opportunities for preserving traditional resources , the manufacturing an utilization of fly ash bricks has now become very important to the country especially from the economic and environmental points of view . 1.2The Fly Ash Bricks by the National Thermal Power Corporation (NTCP) in India In order to overcome with the problem of fly ash waste in India the agencies such as the National Thermal Power Corporation (NTPC) of India had invented a new technology to utilize the fly ash waste by inventing a fly ash brick as a constructing material to build up walls. The fly ash brick can also replace the uses of clay brick in the construction industry. The technology they invented uses a mix of 60 to 80 per cent fly ash, 10 per cent sand, 10 per cent gypsum and 10 to 20 per cent lime that can replaces the use of clay from the soil. The bricks are regarded as strong and high quality. 3
The NTPC has also established a pilot project where they set up a fly ash brick manufacturing plants at their thermal power plant. The project was a success and they have produced approximately 150 million bricks in these plant. So far all of the bricks are used for their in house consumption. The also suggested that a new plant should follow the guide line of the quality standards of IS12894:1990 in order to sustain the quality of the bricks produced. A process outline for manufacturing fly ash bricks is given in Exhibit 1. Exhibit 1 : Process of Manufacturing Fly Ash Bricks 1.3 The Fly Ash Project by Rajiv Sharma and Alok Gupta This case is about 2 entrepreneur Sharma and Gupta who plan to set up a fly ash brick manufacturing plant as they see there is a good opportunity of it. Sharma has been doing some market research and he finds out that there is a good business potential for fly ash bricks.
