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.

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%.

World: Global steel production was 1.86Bnt in 2020, down by 1% year-on-year from 1.88Bn in 2019. The decrease is the first since 2015. The sharpest declines were recorded in the US (17%), Japan (16%), the EU (12%) and India (11%). Chinese steel production rose for a sixth consecutive year to 1.05Bnt, up by 5% from 1.00Bnt. The rest of the world produced 811Mt, down by 8% from 879Mt. China’s share of world steel production rose to 57% from 53%.

India: GM Iron & Steel Company Limited has published plans for the construction of a 0.4Mt/yr slag cement grinding plant in Dhenkanal, Odisha. United News of India has reported that the plant is part of an upcoming construction materials complex, including a 46MW captive power plant, that will cost US$82.7m, according to the company.

India: The Bureau of Indian Standards has granted a licence to Counto Microfine Products (CMP), a joint venture of Ambuja Cements and medical company Alcon Group, for the production of micro-fine Ordinary Portland Cement (OPC) and ground granulated blast furnace slag (GGBFS) cement. The Times of India newspaper has reported that CMP operates a grinding plant in the state of Goa.
