Studies on the removal of zinc by adsorption on two types of flyashes, namely Bokaro Thermal Power Plant Fly ash and Fluidized Bed Combustion Fly Ash from Tata Steel, Jamadoba were carried out. Since industrial waste water often contains high concentration of heavy metals/toxic elements, it was thought worthwhile to …
To meet India's annual growth rate of 7-8 per cent, coal is expected to maintain its dominant share of the electricity generation fuel mix. It is estimated that up to 80-100 million tonnes of flyash is produced each year by the low-quality coal used in India; however, only 10 per …

It is well known that 50-60% of power generated in India is from thermal power stations. These thermal power plants use coal as a fuel. The high ash content of these coals pose a serious problem to the environment. The flyash production rate is about 25 million tonne for every …
What goes into making cement? The obvious answer is: limestone, which makes up approximately 94-95 per cent of Ordinary Portland Cement. But cement is more accommodating: the Bureau of Indian Standards says flyash can comprise up to 35 per cent of cement, and blast furnace slag (bfs)
Scientists have detected an overload of radioactive compounds in the flyash in villages surrounding the 1,260 megawatt Kolaghat Thermal Power Station in West Bengal's Midnapur district. In addition, the tube well water in these villages contain very high levels of toxic elements. While the flyash was found containing high levels …
Fly ash is generated as waste in thermal power plants that run on coal. An ideal use for fly ash is in making Portland Pozzolana Cement (ppc). Though cement companies are producing ppc , the market appears to be biased against it. Why? Because the predominantly used Ordinary Portland Cement …
What are the key factors to consider while buying cement? Quality and strength. Strength is the main criterion for classifying cement. This is defined for 1 day, 3 days, 7 days and finally 28 days. It is the strength after 28 days that is most important. For instance, a new …
it is cheaper, elegantly uses waste from power plants, is less of a drain on scarce natural resources and has better resistance to cracks: cement with fly ash. But the Indian consumer doesn't like it. Companies manufacturing Portland Pozzolana Cement complain consumers prefer ordinary cement (with high compressive strength) for …

Earlier, in the petition it was alleged that toxic waste from the …
A comprehensive, spatially resolved (0.25°×0.25°) fossil fuel consumption database and emissions inventory was constructed, for India, for the first time. Emissions of sulphur dioxide and aerosol chemical constituents were estimated for 1996–1997 and extrapolated to the Indian Ocean Experiment (INDOEX) study period (1998–1999). District level consumption of coal/lignite, petroleum and …
