Two Indians have invented a climate-friendly technology that produces bricks without using any coal whatsoever. The new fly ash brick technology has the potential to completely eliminate carbon emissions from Indias large brick-making industry which burns huge amounts of coal and emits millions of tons of carbon dioxide each year. Another significant benefit of the new technology is that unlike clay bricks that use valuable top soil as raw material, the new method uses fly ash, an unwanted residue from coal-fired power plants. This fly ash is presently dumped on acres of land, damaging both the environment and the health of populations around power plants. The use of fly ash is particularly important as, with Indiasplans to use coal to expand power production, the generation of fly ash is set to increase while the availability of top soil is bound to decrease. A further advantage is that fly ash bricks can be produced in a variety of strengths and sizes. Given the numerous benefits of the new fly ash brick technology, the inventors are providing the technology without invoking the patent. The Government of India has also issued a number of notifications encouraging its use. In addition, a World Bank Project is helping to promote the new method by enabling entrepreneurs to earn carbon credit revenues to offset some of their initial costs. Over 16,000 FaL-G brick plants are now in operation throughout the country, up from just 100 in 2000. Fly ash bricks account for about one sixth of Indias annual brick production, putting over 20 million tons of fly ash to productive use each year. So far, the World Bank project as enabled 108 fly ash brick plants to earn about $ 3.2million, or approx Rs. 14.5 crores, in carbon credit revenues. About 12 percent of these revenues have been allocated for improving the working conditions of fly ash brick plant laborers. technology.
