Japan: Sumitomo Osaka Cement will launch its new sustainability committee on 1 April 2023. The committee will promote initiatives to reduce the producer's CO2 emissions and help it to 'realise a decarbonised society.' The new committee will operate alongside Sumitomo Osaka Cement's existing corporate social responsibility (CSR) committee, which has been in operation since April 2020.
Vicat and Materrup launch raw clay cement joint venture
24 March 2023France: Vicat and Materrup have formed a joint venture to industrialise production and accelerate marketing of Materrup's Clay Cement 1 (MCC1) raw clay cement. The Le Moniteur newspaper has reported that the technology is based on a precursor and activator mixture which removes the need for calcination of the clay. Materrup said that this halves MCC1 cement's CO2 emissions compared with ordinary Portland cement (OPC).
The partners say that clay has better long-term feasibility than other alternative raw materials for cement production, because global reserves are currently 2Tnt.
Brazil: Secil Supremo Cimentos has appointed FLSmidth to carry out a pyro process upgrade at its Adrianópolis cement plant in Paraná. The Denmark-based supplier says that it plans to carry out modifications on the plant's preheater, cooler and related auxiliary equipment. It says the new equipment will expand the plant's capacity to 3900t/day, corresponding to an annual production capacity of 1.42Mt/yr. It will also enable it to increase its alternative fuel (AF) substitution rate to 40%. Secil Supremo Cimentos' AF mix consists of shredded tyres, wood and other refuse-derived fuels.
FLSmidth's head of capital sales, Jens Jonas Skov Larsen, said “We are grateful for our continued partnership with Supremo, which has consistently invested in the latest technology. As the plant was already operating an ILC five-stage preheater from FLSmidth, it was well positioned to use AF.”
Poland: Lafarge Polska has signed a 10-year power supply agreement with Germany-based energy provider RWE Supply & Trading. Under the contract, Lafarge Polska will receive renewable energy from Windfarm Polska III on the coast at Sztum, Pomeranian Voivodeship. It is owned by German state-owned Stadtwerke München (SWM).
Renewables Now News has reported that Lafarge Polska is currently building a 41MW solar power plant at the site of its former Wierzbica cement plant in Masovian Voivodeship. This will cover a further 10% of its energy consumption.
Cembureau voices support for EU carbon storage quotas
23 March 2023EU: Cembureau, the European cement sector association, has lobbied the EU in support of a draft act for the setting of CO2 storage capacity quotas for member states. It called for the simplification and acceleration of permitting procedures for storage sites. It also encouraged policymakers to strengthen the focus on CO2 transport networks, ensuring fair access conditions for cement plants.
Cembureau said "Whilst a mix of technologies are needed to decarbonise cement production, carbon capture, utilisation and storage (CCUS) is particularly critical, as our sector faces unavoidable process emissions. A large number of CCUS pilot and demonstration projects have been launched by cement companies across Europe, with the first of them becoming operational as early as 2024. The pipeline of investments is particularly strong – for instance, the latest ETS Innovation Fund call awarded over Euro500m three cement CCUS projects."
Germany: Solid UNIT Germany, the German construction sector association, has launched its climate advisory board. The board will advise on and jointly instigate initiatives together with the Solid UNIT Germany management board. Its membership comprises representatives from the German Sustainable Building Council (DGNB), the Institute for Sustainable Construction in Germany (ARGE) and the Federal Chamber of Architects, along with members of parliament.
Solid UNIT Germany managing director Thomas Zawalski said "To cope with the Herculean task ahead of us, it is important to bundle experience. Faster CO2 reduction in the building sector is only possible through joint action by all stakeholders."
Belgium: Holcim Belgium has received an environmental permit for the kiln upgrade for its 100% decarbonisation of its Obourg cement plant. Agency Belgium News has reported that the upgraded kiln will employ a 'new incineration concept' to enable it to replace limestone with alternative raw materials. It will reduce the plant's thermal needs by 40% and its CO2 emissions per tonne of clinker by 30%. Construction will commence in late 2023. The kiln replacement will support a carbon capture installation as part of the GO4ZERO project.
The first phase of the GO4ZERO project is running from 2022 to 2025, and commands total investments of over Euro350m.
UK: The UK government has committed to investments worth Euro22.8bn in early deployments of carbon capture technology. It will announce a shortlist of new projects for deployment later in March 2022.
The government said "This unprecedented level of funding for the sector will unlock private investment and job creation across the UK, particularly on the east coast and in the North West of England and North Wales. It will also kick-start the delivery of subsequent phases of this new sustainable industry in the UK."
Ireland-based Ecocem responded to the budget with a call for funding for more short-term areas besides carbon capture. It said these will be essential in order for the UK cement and concrete industry to reach its 45% decarbonisation target by 2030. The slag-based cement products company called for funding for low-clinker technologies which have already been developed and can be rolled out at scale before 2030, until carbon capture becomes a 'scalable, viable option.'
Canada: The city administration of Langford in British Columbia plans to enact regulations requiring all public and private projects to use reduced-CO2 concrete. It plans to support the rules with parallel measures affecting the design of buildings.
Victoria News has reported that the city authorities previously mandated reduced-CO2 cement for all projects in June 2022, but subsequently relaxed the regulations after only one company – Butler Concrete and Aggregates – completed the transition. Butler Concrete and Aggregates produces its reduced-CO2 concrete using slag cement supplied by Lafarge Canada.
Nexe appoints ThyssenKrupp Industrial Solutions for new kiln line and carbon capture installation
15 March 2023Croatia: Nexe has awarded a contract to Germany-based ThyssenKrupp Industrial Solutions for the construction of a new clinker line and carbon capture installation at its 0.6Mt/yr Nasice cement plant. The Poslovni Dnevnik newspaper has reported that the work will cost Euro400m. When commissioned in 2029, the upgraded plant will produce carbon neutral cement and despatch 700,000t/yr of CO2 by pipeline for storage near Bockovac in Osijek-Baranja County.
