New Zealand: Fletcher Building says that its subsidiary Golden Bay cement is waiting to embark on a US$119 – 178m course of capital expenditure (CAPEX) investment. However, the group said that it will first require ‘clarity from the government’ on any upcoming changes to industrial CO2 emissions allocations or border adjustments.

CEO Ross Taylor said “Until we get certainty there, we really can’t pull the cord.” He added “There’s a good pipeline of existing stuff which will really start maturing in two or three years, but there’s another really sizeable pipeline beyond that.”

Fletcher Building invested a total of US$182m across its businesses during the 2023 financial year, which ended in June 2023. The Bay of Plenty Times newspaper has reported that the investments are part of the group’s growth strategy for the four-year period up to the end of the 2027 financial year. Planned areas for investments include adding value to the group’s wood products by developing its alternative fuel (AF) capacity. The growth strategy has a budget of US$474m.

New Zealand: Fletcher Building recorded sales of US$5.07bn during the 2023 financial year, down slightly year-on-year from US$5.08bn in the 2022 financial year. Its earnings before interest and taxation (EBIT) fell by 29% to US$296m from US$419m. The drop in earnings was mainly attributed to additional costs allocated to the New Zealand International Convention Centre and Hobson Street Hotel project. Adjusted for significant items, the group’s EBIT rose by 6% to US$477m from US$452m.

Throughout the year, Fletcher Building’s cement subsidiary Golden Bay Cement co-processed 100,000t of waste as alternative fuel (AF). The producer awarded a bottom ash supply contract to Huntly Power Station. It also launched EcoZero carbon neutral cement, which is its EcoSure reduced-CO₂ cement with the remaining emissions offset.

Chief executive officer Ross Taylor said “Looking forward to the 2024 financial year, we expect some further tightening in our overall volumes and so our focus remains on strong customer performance, cost control and pricing disciplines across our businesses. We have shown we are well equipped to continue performing solidly through the cycle.”

Spain: Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO₂, using solar heat. La Tribune de Genève Online News has reported that Synhelion’s thermochemical reactor further helps to capture CO₂ emissions from clinker production. A study by the Swiss Federal Institute of Technology Lausanne indicated that this can halve the cost of carbon capture at cement plants, to below Euro85/t.

Thailand: Siam Cement Group (SCG) recorded sales of US$7.22bn in the first half of 2023, down by 17% year-on-year from US$8.69bn. Cement and building materials accounted for US$2.6bn (36%) of sales, behind chemicals at US$2.74bn (38%). The company's earnings before interest, taxation, depreciation and amortisation (EBITDA) dropped by 24% to US$915m from US$1.21bn. Meanwhile, its profit excluding extra items dropped by 49% to US$279m from US$543m. Cement and building materials contributed 78.5m (28%) of group profit, down by 38% from US$126m (23%).

During the first half of 2023, sales of alternative CEM-I and CEM-II cement rose above 50% of SCG's cement sales for the first time, compared to 41% throughout 2022. The group substituted 22% of all cement fuel with alternative fuel (AF) across its operations, and 22% of cement fuel in its Thai domestic business. SCG invested US$91.5m in capital expenditure in its cement and building materials business throughout the first half of 2023.

Peru: Grupo Gloria subsidiary Cemento Yura plans to transition its Yura cement plant from using coal to alternative fuels (AF) in its cement production. Additionally, the producer will build a 30MW solar power plant at the site. The Gestión newspaper has reported the total value of the upgrades as US$50m. Both projects are scheduled for commissioning in mid-2025.

In the 2023 financial year, which ended on 30 June 2023, Peruvian cement despatches fell by 8% to 12.6Mt.

Brazil: Votorantim Cimentos has secured a US$150m loan from the International Finance Corporation for an upgrade to its Salto de Pirapora cement plant in São Paulo. The producer aims to increase the alternative fuel (AF) substitution rate at the 4.8Mt/yr plant, and reduce its CO₂ emissions. It says that the loan is tied to sustainability performance indicators (SPIs), based on the reduction in the plant’s Scope 1 CO₂ emissions.

US: Buzzi subsidiary Buzzi Unicem USA has published an update following a fire on the evening of 13 July 2023. The producer said that it first detected smoke from an alternative fuel (AF) store that housed wood chips and shredded tyres. Staff contacted the fire service, which brought the blaze under control without any injuries. The fire damaged the siding of the storehouse, as well as some electrical equipment. The producer said that the Stockertown cement plant did not lose electrical power, and that it is currently evaluating the extent of the damage.

Plant manager Rad Slavov said “I want to thank all the emergency responders for their quick response and professionalism in getting the fire under control swiftly.”

Portugal: Cimpor Portugal has signed a contract with Germany-based KHD Humboldt Wedag (KHD) for an upgrade to production line 7 at its Alhandra cement plant. The project is intended to increase the production capacity at the plant to 3600t/day from 3000t/day and increase the line’s alternative fuels thermal substitution rate to over 80%. It will also be the first installation of KHD’s Pyrorotor alternative fuel combustion reactor in the country.

The scope of the engineering and supply contract comprises:

• New HKSK 224/335 preheater ID fan
• New downcomer duct
• New preheater with 8064/5-type HEM cyclones
• Pyroclon R calciner with Pyrotop mixing chamber. The Pyroclon R will utilize fine refuse-derived fuel (RDF) and natural gas
• 4m x 10m Pyrorotor alternative fuel combustion reactor
• Pyrobox coal firing system for process start-up and operation balancing
• Shortening of the existing kiln and installation of new kiln inlet chamber with bypass extraction
• New kiln drive station 2 (the existing girth gear and two pinions will be reused)
• New kiln hood and take-off of tertiary air from the cooler roof
• New main kiln burner designed to use more than 50% alternative fuels (but will also be capable of burning natural gas, as well as liquid fossil and alternative fuels)
• New Pyrofloor PFC²829AW cooler with a Pyrocrusher PRC 420-3ES clinker crusher.

KHD will also be supplying its KHD ProMax software product as part of the project.

Matthias Mersmann, chief technology officer at KHD, said “The decision by Cimpor Portugal to opt for KHD pyroprocessing equipment - and especially the Pyrorotor - underlines the leading market position of KHD, as well as the outstanding capability of KHD’s unique alternative fuel-processing solution.”

Project execution will be led by KHD Germany, with support from Humboldt Wedag India and the Turkish branch office of Humboldt Wedag. Commissioning of the upgraded production line is scheduled for 2025.

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

Belgium: The European cement association, Cembureau, has asked the Europen Union (EU) to provide a regulatory framework to support the work of the European cement industry in co-processing waste composite materials as alternative raw materials. The materials in question consist of glass, carbon or other fibres and polymer matrices. The association called on the EU to recognise co-processing as ‘recycling’ under the EU Waste Framework Directive, to establish waste composite materials collection schemes and phase out landfilling, and to introduce dedicated waste codes for the materials. Cembureau said that the last of these proposals would help to increase visibility and attract investments.

Cembureau set out its proposals in a joint statement with resins associations Cefic UP/VE and Cefic Epoxy Europe, boating association EBI, composite materials association EuCIA, glass fibre association Glass Fibre Europe and wind energy association WindEurope.
