BHUBANESWAR: National Aluminium Company Limited (NALCO), country's leading producer and exporter aluminium, here on Monday reported commissioning of The High Concentration Slurry Disposal (HCSD) system in its 1080 MW captive power plant.
Pulverized coal fly-ash has been evaluated as wet-end filler in manufacture of specialty products such as decorative laminate-grade base papers. Fine sized fly-ash is available abundantly as solid waste from coal based thermal power plants. Non-magnetic fly ash particles smaller than 35 um were used as wet end filler.
Uranium content in groundwater varies markedly depending upon geological terrain, climate, proximity of uranium deposits, as well as composition of the water. In India, the average reported range of uranium in groundwater is from 0.01 to 19.6 micrograms/litre (ug/L).
Growing pollution thanks to rapid industrialisation has prompted the state government to draw up plans to address the problem.
The state has at least 107 sponge iron plants, which contribute significantly to pollution. Besides, there are several thermal plants and coalfields in Talcher-Angul and Ib valley area.
ANGUL: The core committee for fly ash utilisation of Angul district has decided to use void coal mine and low-lying areas across the district to dump huge quantity of dry ash generated from the power plants in the district.
Six districts in the State, where power is generated, have formed their respective core committees on fly ash utilisation.
The joint action committee of residents of the town formed against air pollution being caused by the thermal power house of the PSEB here has decided to file a petition on the issue in the High Court as the authorities concerned have failed to check the emission of ash that is playing with the health of people.
Incorporating the beneficial use of industrial by-products into the industrial ecology of an urban region as a substitute or supplement for natural aggregate can potentially reduce life cycle impacts.
