Philippines: Metal and ores producer Global Ferronickel Holdings (FNI) plans to invest in clinker production operations. The company has indicated that it will also begin producing limestone to supply any clinker plants that it builds. The Manila Bulletin newspaper has reported that FNI's plans also include new ventures into value-added processing, including through the establishment of a ferronickel processing plant and nickel matte processing facility.
Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO2 emissions by 400,000t per decade.
Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO2 company."
Indocement Tunggal Prakarsa and Amita Holdings launch feasibility study towards net zero cement production
21 June 2023Indonesia: Indocement Tunggal Prakarsa has engaged Japan-based environmental consultancy Amita Holdings to support a two-year feasibility study to investigate ways to make its cement production carbon neutral. The study will commence with trials of industrial wastes as alternative raw materials and municipal solid waste as refuse-derived fuel. Amita Holdings says that it is in the process of building a recycling-based society in Indonesia, in partnership with Indocement Tunggal Prakarsa.
Amita Holdings supported the establishment of the community-led Meguru waste sorting facility in Central Java. Two of Indocement Tunggal Prakarsa’s cement plants – the 18Mt/yr Citeureup cement plant and 4.1Mt/yr Paliman cement plant – are situated in neighbouring West Java.
Canada: The district council of Capital Regional District (CRD) says that it expects to resume sending biosolids to Lafarge Canada's Richmond cement plant in early June 2023. This follows a reported reduction in production at the unit in 2023 and 2022, according to the Times Colonist newspaper. The 1.1Mt/yr cement plant previously used biosolids supplied by the CRD as an alternative fuel in its cement production. However, during the current hiatus the biosolids have been sent to landfill instead.
The Richmond cement plant is the site of the CO2MENT carbon capture and utilisation project. The project proceeded to its third phase, which consists of a capture capacity expansion and the installation of a liquefaction plant, in May 2023.
Heidelberg Materials North America inaugurates expanded Port Canaveral slag cement plant and terminal
26 May 2023US: Heidelberg Materials North America has inaugurated the Port Canaveral slag cement plant and terminal in Florida, following an expansion. MENAFN News has reported that the producer invested US$24m in the installation of a new roller press at the facility.
Heidelberg Materials North America said "Heidelberg Materials' investment in the Port Canaveral slag cement facility is reflective of our commitment to supporting sustainable and resilient construction projects in the state of Florida and throughout the country. It is also aligned with our goal to significantly reduce our carbon footprint by 2030 and another milestone in our overall strategy to grow our portfolio of more sustainable products, technologies and customer-focused solutions on the path to Net Zero."
Canada: A study led by Douglas Geoffrey in Calgary, Alberta, has patented a method of producing cement from calcium carbonate precipitated in the carbonation of brine. The method mixes the mineral with magnesium oxide and cures it to form cement.
Geoffrey noted that the brine may derive from multiple industrial processes, including fossil fuel and potash production, geothermal power generation and desalination.
Golden Bay Cement secures bottom ash supply
09 May 2023New Zealand: Golden Bay Cement has signed a deal with Genesis Energy for a supply of bottom ash from Huntly power plant for use in cement production at its Portland cement plant in Northland. Genesis Energy generates 20,000t/yr of bottom ash at the Huntly plant, situated in Waikato, 260km south of the Portland cement plant. The plant currently uses 15,000t/yr of fly ash from the Huntly power plant in its operations. The producer was previously investigating the use of volcanic ash in cement production in 2022. It currently uses waste tyres and wood waste as alternative fuels (AF) to produce its EcoSure low-carbon general-purpose cement.
Golden Bay Cement's general manager Gian Raffainer said "We are driven to decarbonise and achieve 30% less carbon by 2030. Contributing to waste reduction at a large scale for the benefit of all New Zealanders is incredibly exciting. It is a win-win for the environment and for Kiwis who want to use more environmentally friendly products."
Holcim invests in Coomtech
05 May 2023UK: Switzerland-based Holcim has invested in Coomtech, a developer of low-emission kinetic drying technology for raw materials. The group says that Coomtech's technology emits up to 75% less CO2 than traditional drying methods and enables increased use of recycled materials in cement and concrete. Holcim subsidiary Aggregate Industries previously collaborated with Coomtech on fly ash drying at a UK power plant.
Edelio Bermejo, head of global research and development said "At Holcim, we are continuously working to implement greener operations for a net-zero future, and to increase the use of recycled materials in our products to drive circular construction. Coomtech's low-emission drying technology helps us meet both these goals. I look forward to working with them as a key partner in our journey to decarbonise buildings."
Holcim acquires Sivyer Logistics
06 April 2023UK: Holcim has acquired leading London construction and demolition waste (CDW) recycling company Sivyer Logistics. Sivyer Logistics produced 500,000t of recycled aggregates and manufactured soils from 1Mt of CDW across its six sites in 2022. Holcim says that the acquisition represents a step towards realising its target of 10Mt/yr of construction and demolition waste in Holcim products by 2025.
The group’s Europe regional head Miljan Gutovic said “Sivyer Logistics is an excellent addition to help us drive circular construction.” He added “I look forward to welcoming all employees of Sivyer Logistics and investing in our next era of growth together.”
Cemex publishes Integrated Report 2022
28 March 2023Mexico: Cemex has reviewed its global sustainability and financial performance during 2022 in its Integrated Report 2022. During the year, the group reduced its specific CO2 emissions by 9% from 2020 levels and by 30% from 1990 levels. It achieved a target of US$1bn-worth of investment in strategic projects over a period begun in 2020. Projects included the execution of water optimisation plans at 20% of Cemex sites in high-water stress areas. Cemex co-processed 27Mt of waste as alternative fuel (AF) in its global cement production - 67 times greater than its own non-recyclable waste footprint - and achieved an AF substitution rate of 35%. Meanwhile, the group also reduced its cement's clinker factor to 74%. Its Vertua reduced-CO2 concrete range accounted for 33% of its concrete sales. During the year, Cemex launched the world's first net zero, fully electric heavy concrete mixer truck.
In 2022, Cemex recorded sales of US$15.6bn, down by 12% year-on-year, and reduced its debt to US$408m.
