Vedanta Aluminium is working with hundreds of local brick manufacturing MSMEs near its operations in Odisha and Chhattisgarh, transitioning them away from mud bricks.
Fly-ash is a by-product of thermal power generation using coal, which caters to electricity requirement of Vedanta’s aluminium smelters.
The inherent properties of fly-ash find impactful usage in the cement, construction & infrastructure industries, to offer three-fold benefits in terms of cost, quality and sustainability.
The company supplies fly ash from its Jharsuguda and BALCO plants to cement industry for the production of low-carbon ‘green’ cement.
Besides improving product quality, in cement manufacturing, every tonne of fly-ash used can help save around 700-800 kg of carbon emissions, 4.2 million KJ of energy, and 341 litres of water.
Bricks made of fly-ash are not only lighter and stronger than traditional clay bricks, but also play a crucial role in preserving nutrient-rich topsoil from being used as raw material.
This amounts to estimated savings of 1.9 metric tonnes of topsoil for every tonne of ash brick manufactured.
In fact, for every tonne of ash bricks manufactured, an estimated 5900 kg of carbon dioxide equivalent emissions are avoided. It also makes for a healthier working environment for those involved in the brick manufacturing process. “The company has also entered a long-term partnership with the National Highways Authority of India (NHAI) for building greener roads with fly-ash in Odisha” It informed
