India: Construction is underway on a section of National Highway 66 in Maharashtra which is being built of concrete made from ground granulated blast furnace slag (GGBFS) and slag cement. India Today News has reported that the Central Road Research Institute developed the technology, in partnership with the National Institute for Transforming India Aayog and the Council of Scientific and Industrial Research.

India: The Border Roads Organisation (BRO) has used steel slag to construct a 1km section of National Highway 713 that connects Arunachal Pradesh's Kurung Kumey district to the Chinese border. The slag material was donated by Tata Steel and transported from Jamshedpur to Arunachal Pradesh by Indian Railways free of charge, according to the Press Trust of India. The project was an initiative of BRO Director General Lt Gen Rajeev Chaudhry to introduce sustainable new technologies with the help of Central Road Research Institute-Council for Scientific & Industrial Research (CRRI-CSIR) and Tata Steel.

India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."

India: The Border Roads Organisation (BRO) plans to launch a pilot scheme in Arunachal Pradesh to build roads using steel slag. It will work with the Central Road Research Institute (CRRI), according to the Press Trust of India. The intention is to explore building long-lasting roads using an alternative materials to conventional aggregates. The topography of the state - with high annual rainfall, forest vegetation and soil diversity – has also prompted the project partners to try using new materials and techniques.

India: Three new Indian concrete companies have separately secured agreements for the use of Finland-based Betolar’s Geoprime alkali-activated slag and fly ash additive. Reuters News has reported that the companies are Balaiji Cement Products, Shiv Tiles and SNEH Precast. Engineering company Godrej & Boyce has also signed a letter of intent with the supplier for pilot production of concrete blocks, paving slabs and other elements.

Betolar expects producers to achieve global concrete production volumes of 250,000t/yr of concrete containing Geoprime by 2023.

India: The first steel slag road in India has been built in Surat, Gujarat. The 1.2km road is located at Hazira Port, according to the Times of India newspaper. It was constructed by using steel slag aggregate in place of natural aggregate. The higher strength of the material has also allowed for the thickness of the road to be reduced by 30%. Around 100,000t of steel slag was used. The joint project was a collaboration between the Council of Scientific and Industrial Research, the Central Road Research Institute, the Union Ministry of Steel, government think-tank NITI Ayog and ArcelorMtttal-Nippon Steel.

India: Dalmia Cement (Bharat) has started using two electric trucks to transport slag as part of its E-Truck project. They are being used to transport slag from the Steel Authority of India Limited’s (SAIL) Rourkela plant to the cement producer’s plant at Rajgangpur. The company has also commissioned two charging stations at its Rajgangpur plant and three more are to be installed by March 2022. The E-Trucks initiative is intended to reduce Dalmia Cement Bharat’s carbon emissions from transportation and decrease its logistics costs. A further 20 electric trucks are intended to start use by the end of the 2022 financial year.

“Achieving environmental sustainability has always been a priority for us at Dalmia Cement Bharat from a business and a social standpoint. While we are grateful that our government is creating the right policy and investment environment that encourages organisations to take positive environmental action, as private organisations we need to take the lead,” said Mahendra Singhi, managing director and chief executive officer, Dalmia Cement Bharat. He added that the company was confident that it would able to achieve its sustainability goal of becoming carbon negative by 2040.

India: The Indian Green Building Council (IGBC) has certified the sustainability claims of Dalmia Cement’s portfolio of blended cements. The portfolio consists of composite cement, Portland pozzolan cement and Portland slag cement. The council employed a full-cycle assessment of the cements’ impacts.

Head of sales, marketing and logistics Sanjay Wali said “We see GreenPro’s accreditation as a milestone in our journey to becoming carbon-negative by 2040. This also reaffirms our blended cement products’ green supremacy, which is accelerating the global transition from a grey to green reality.”

India: Tata Steel has begun the export of Linz-Donawitz (LD) slag from its steel production processes to Bangladesh. The United News of India has reported that a Bangladeshi cement producer has purchased the material for use in its cement production. China-based cement shipping company Cemcoa will deliver the slag.

Chief operating officer Subodh Pandey said that Tata Steel continually pursues operational and market-facing innovations by creating value out of its by-products, as part of its quest to a sustainable future. It has achieved 100% granulated blast furnace slag (GBFS), fly ash and LD slag recycling.

World: World Steel Association data shows that crude steel production grew by 14.4% to 1Bt in the first half of 2021. Production in Africa and South America rebounded the fastest although these areas are amongst the smallest production regions. China produced 563Mt of crude steel in the reporting period, a rise of 11.8%, much more than Africa and South America combined. India, the next biggest manufacturer, produced 57.9Mt, a rise of 31.3%.
