Vedanta on Monday stated its aluminium vertical has invited partnerships from cement producers like ACC, UltraTech Cement and JK Cement to make use of its by-products for manufacturing low-carbon cement.
In a nationwide workshop performed with world business specialists, the corporate expressed its curiosity for long-term collaboration with cement business gamers on alternatives of utilizing fly ash, a by-product in thermal energy era, and bauxite residue in cement manufacturing.
“Vedanta aluminium enterprise…invitations partnerships from cement producers for utilizing its by-products for manufacturing low-carbon cement,” the corporate stated in an announcement.
The cement business, which is exploring viable options to supply cement extra sustainably, is the right round economic system accomplice for Vedanta Aluminium, it stated.
“Lengthy-term strategic collaborations, resembling between Vedanta and India’s key cement producers, won’t solely get rid of vital volumes of commercial waste from the system, but additionally present the trifecta of high quality, sustainability and value advantages for the cement business.

Fly ash and bauxite residue, the 2 most voluminous by-products generated by the aluminium business, can be utilized in cement and concrete manufacturing, offering cement producers vital advantages when it comes to high quality output, price and sustainability.
Fly ash can partially change cement in concrete (or be used to supply blended cement), considerably bettering sturdiness and workability of cement. With a 30-33 per cent mixing ratio, fly ash may help save 270 kg of carbon emissions for each tonne of cement produced.
Bauxite residue may be added to the uncooked combine in clinker manufacturing to interchange virgin bauxite, bettering its hydraulic properties and energy.
Owing to excessive focus of iron oxide and alumina, bauxite residue is a greater substitute for laterite, utilized in clinker manufacturing. Furthermore, the residual caustic in bauxite residue helps in controlling the emission of sulphur when used straight, making it a greater match for the aim. Each fly ash and bauxite residue being industrial wastes themselves, include vital price and power benefits as properly.
