Indonesia: Semen Baturaja has signed a memorandum of understanding with Huadian Buket Asam Power. Under the agreement, the producer will supply the power company with limestone for its flue gas desulfurisation (FGD) process in exchange for fly ash, bottom ash and gypsum. The agreement will last two years until March 2023.

The cement producer’s managing director Sumsal Saifudin said, “This collaboration is a form of synergy between the two companies to improve competitiveness, which is much-needed in facing an increasingly competitive industrial environment, by taking advantage of opportunities for the creation of new revenue streams and cost transformation.”

US: Charah Solutions will sell and market production fly ash from NV Energy’s North Valmy coal-fired power plant in Valmy, Nevada under a contract with the power producer. The contract runs until 2025. The company will distribute the ash through its 40-location nationwide MultiSource materials network as supplementary cementitious material (SCM) for cement and concrete production.

President and chief executive officer Scott Sewell said, “We are delighted to partner with NV Energy to manage their fly ash marketing needs at Valmy, while supplying our concrete producers with the high-quality material they need.”

Australia: Boral’s group net sales fell by 9% year-on-year to US$2.10bn in the first half of its 2021 financial year from Euro2.78bn in the corresponding period of its 2020 financial year. Earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 1% to US$376m from US$381m. Net profit after tax remained consistent with previous first-half levels at US$121m. The group noted good value creation from its sale of its 50% stake in USG Boral to Germany-based Knauf for US$1.02bn, which it expects to conclude in the second half of the 2021 financial year.

Chief executive officer and managing director Zlatko Todorcevski said, “While market conditions across the sector remain uncertain, we have made strong early progress to reset our portfolio of businesses, in line with our commitment to shareholders to transform Boral into a more agile, resilient and profitable company. Much work remains to be done but we are well on our way. Our half-year results were impacted, as we expected, by a decline in multi-residential and non-residential construction activity in Australia, particularly in New South Wales, and the completion of a number of major projects ahead of materials demand from new projects coming through. We are in a good position to supply demand when activity in Australia picks up.” He added that housing demand in the North American region strengthened throughout the first half of 2021.

Cement sales revenue and earnings from the group’s Boral Australia subsidiary were reported as stable. The group has also conducted a study of the US fly ash market as part of its ongoing portfolio review. It plans to strengthen its fly ash business in the long term due to expected demand growth.

India: Star Cement has announced the completion of its US$61m grinding plant project in Jalpaiguri, West Bengal. The Press Trust of India has reported that the 2Mt/yr grinding plant is set to enter production shortly. This will bring the company’s installed capacity to 6.3Mt/yr. The company intends to source clinker from its integrated cement plant in Meghalaya that has mines nearby. Fly ash will be procured from West Bengal or Bihar.

Star Cement plans to discontinue its lease of another grinding plant in Siliguri, West Bengal, at the end of January 2021.

UK: DB Group has supplied its Cemfree concrete product to a site in Birmingham, West Midlands for use by the Environment Agency in a flood defence project. It says that the agency will use the concrete “for kerb bedding and backing over several kilometres in conjunction with various recycled products in an effort to reduce the projects’ carbon footprint.” Cemfree is a low carbon concrete made using ground blast furnace slag (GGBS) and pulverised fly ash.

Tanzania: Mbeya Cement, part of LafargeHolcim Tanzania, has launched Lafarge Tembo Pozzi, a pozzolana-based cement product. It is intended to replace imports of fly ash, according to the Daily News newspaper. At present the country imports 40,000t/yr of fly ash for the construction industry.

India: BK Birla Group subsidiary Mangalam Cement has launched Mangalam ProMaxX, a premium fly ash Portland pozzolana cement (PPC) that it says boasts “high one-day strength and also high 28-day ultimate strength.” The company says that the new cement is “an environmentally-friendly alternative with all the performance abilities of Mangalam Cement’s Birla Uttam cement.”

India: Dalmia Cement has imported 3830t of fly ash from a National Thermal Power Corporation (NTPC) power plant in Uttar Pradesh for use at its 0.8Mt/yr-capacity integrated Calcom cement plant in Assam. United News of India has reported that the supplementary cementitious material (SCM) travelled over 1000km.

62.9GW-total capacity NTPC produces 65Mt/yr of fly ash, some of which is used by ACC at its cement plants in Uttar Pradesh, Madhya Pradesh and Punjab.

US: CRH subsidiary Ash Grove Cement says that it is undertaking an upgrade of its Port Manatee, Florida deep water cement terminal to install a high capacity FLSmidth Kovako unloader and modernise existing material transfer and electrical systems, as well as establishing self-loading capabilities. The aim of the upgrade is “to improve Ash Grove’s capacity to import cement clinker, slag and fly ash to meet the existing and future needs of customers in the Florida and South Georgia markets.

Regional president Monica Manolas said, “The underlying fundamentals in the Florida market are positive with good population and employment growth. The upgrade of the Port Manatee import terminal will expand our capabilities and strengthen our ability to meet growing demand in the region.”

The company says that construction will begin in early 2021 and the upgraded terminal will open in late 2021.

Singapore: Jurong Port has ordered three Siwertell ship unloaders from Bruks Siwertell to handle cement imports. The port’s cement terminal already has three Siwertell ship unloaders that have been used for over 20 years. Two of these will be replaced as part of the upgrade project.

The three new ST 490-M screw-type rail-travelling unloaders will each discharge cement, fly ash and cement slag from vessels up to 50,000dwt at a continuous rated capacity of 800t/hr. Two of the new unloaders are scheduled for delivery in May 2022 and the third by the end of 2022. All will be fully assembled prior to delivery and transported by heavy-lift ship. Final commissioning and performance tests will be carried out in Jurong Port.
