France/Switzerland: A technology roadmap by the Cement Sustainability Initiative (CSI) and the International Energy Agency (IEA) sets out a combination of technology and policy solutions that could reduce CO2 emission from the cement industry by 24% by 2050. The Low-Carbon Transition in the Cement Industry report updates the first global sectoral roadmap produced in 2009. It aims to identify and develop international collaborative efforts and provide evidence for public and private sector decision-makers to move towards a more sustainable cement sector that can contribute to long-term climate goals.
“The first exercise carried out in 2009 had demonstrated its added value to help the sector identify solutions and enablers to reduce its CO2 emissions and it was essential to adjust this projection with the latest robust emissions data from the CSI’s Getting The Numbers right (GNR) database and the potential of latest technologies developed by the European Cement Research Academy (ECRA),” said Philippe Fonta, managing director, CSI of World Business Council for Sustainable
Development (WBCSD).The report aims to present a way to help the cement industry play its part it meeting the IEA’s 2°C Scenario (2DS) by 2050, which seeks to limit average global temperature increases to 2°C. The report forecasts that global cement production is set to increase between 12 - 23% by 2050 due to rising global population and urbanisation. Despite increasing efficiencies, direct carbon emissions from the cement industry are expected to rise by 4% globally by 2050 under the IEA Reference Technology Scenario (RTS), a base case scenario that takes into account existing energy and climate commitments under the Paris Agreement. The CSI and IEA argue that the low-carbon transition of the cement industry can only be reached with a supportive regulatory framework as well as effective and sustained investments. They say that meeting the RSI requires more investment, with a
potential doubling to meeting the 2DS. Governments, in collaboration with industry, can play a determinant role in developing policy and regulatory mechanisms that unlock the private finance necessary for such a boost in investment.The roadmap uses a bottom-up approach to explore a possible transition pathway based on least-cost technology analysis for the cement industry to reduce its direct CO2 emissions in line with the IEA’s 2DS. Reaching this goal, the CSI and IEA say, would require a combination of technology solutions, supportive policy, public-private collaboration, financing mechanisms and social acceptance.
Improving energy efficiency and switching to alternative fuels, in combination with reducing the clinker content in cement and deploying emerging and innovative technologies like carbon capture and the use of alternative binding materials are the main carbon-mitigation methods available in cement manufacturing. Further emissions savings can be achieved by taking into account the overall life cycle of cement, concrete and the built environment. The roadmap outlines policy priorities and regulatory recommendations, discusses investment stimulating mechanisms and describes technical challenges with regard to research, development and demonstration.
India: Kakatiya Cement, Sugar & Industries plans to reopen its 2.97Mt/yr cement plant at Dondapadu in Telangana following its closure on pollution grounds in October 2017. Following the installation of online SPM stack monitoring equipment and connections to the Central and State Pollution Control Board servers, the company is ‘hopeful’ that the plant will be able to restart operations by the end of April 2018. The cement producer is currently obtaining clearance from the Telangana State Pollution Control Board.
India: The Central Pollution Control Board (CPCB) has issued a show cause notice to Parasakti Cement for processing hazardous waste like battery scrap and operating without permission. The CPCB also noted that the particulate matter emissions from clinker rollers and cement mill exceeded the revised standards, according to the Times of India newspaper. The cement plant, based at Guntur in Andhra Pradesh, has been given 15 days to remedy the situation. Previously in 2016 the company said it was complying with the emissions regulations.
Locals protest against pollution at Kohat Cement plant
28 February 2018Pakistan: Local residents have protested about air pollution from the Kohat Cement plant. They demanded that the plant install air filters as soon as possible, according to the Dawn newspaper. The protestors also alleged that the company’s employment of local workers had dropped to 5% from 75% following its sale. The cement company says that it has hired a Chinese engineering firm to run a survey of its emissions. In 2016 the Environmental Protection Agency ordered Kohat Cement to stop production as its dust control unit was ‘out of order.’
Canada: The Cement Association of Canada has supported emission reduction schemes in Alberta and Ontario. The Albertan provincial government has released its overarching policy framework for the Output-based Allocation System and the Ontario government has run its fourth and final cap and trade auction before formally linking with California and Quebec in 2018.
The introduction of an Output-based Allocations (OBA) System in January 2018 will transition Alberta’s regulated facilities from the current Specified Gas Emitters Regulation (SGER). The OBA will set an industry specific performance benchmark for emissions-intensive, trade-exposed industries (EITEs), which includes the province’s two cement plants, Lafarge in Exshaw and Lehigh in Edmonton. The benchmark combined with output-based allocations is intended to drive best-in-class performance while maintaining the competitiveness of industries in Alberta.
Ontario raised US$330m bringing total proceeds from the system to date to around US$1.5bn. The proceeds are to be reinvested into initiatives that will further reduce greenhouse gas emissions.
“From the cement industry’s perspective, the framework demonstrates that the Alberta government understands the pressures EITE industries face to remain competitive in the global market. Climate change is the single most important issue facing our society today and Alberta’s Climate Leadership Plan lays the foundation for industries to play a major role in assisting government in meeting its 2030 targets and transitioning to a low carbon economy,” said Michael McSweeney, President and chief executive officer (CEO) of the Cement Association of Canada.
With respect to Ontario he added that the Canadian cement industry believes that cap and trade systems are the most effective means of delivering environmental results while putting a price on carbon. “Linkage with California and Quebec is also an important feature of the Ontario system: the broader the market, the more likely it will be that price will reflect the true incremental cost of reducing emission,” said McSweeney.
US: OGCI Climate Investments has made in an investment in Solidia Technologies to support the adoption of Solidia’s patented cement and concrete technology using CO2.
The Oil and Gas Climate Initiative (OGCI) is a chief executive officer (CEO) led initiative of 10 oil and gas companies that collaborate on action to lead the industry response to climate change. OGCI Climate Investments, its investment arm, supports the development, deployment and scale up of new technologies that are intended to reduce greenhouse gas emissions.
“We believe that Solidia Technologies’ product and process can provide a step change in lowering the greenhouse gas and water footprint of the cement and concrete industry,” said OGCI Climate Investments CEO Pratima Rangarajan.
Solidia Cement is a non-hydraulic cement composed primarily of low-lime-containing calcium silicate phases, such as wollastonite and pseudowollastonite (CaO·SiO2) and rankinite (3CaO·2SiO2). The setting and hardening characteristics of Solidia Cement are derived from a reaction between CO2 and the calcium silicates. The company uses a patented process called reactive hydrothermal liquid phase densification (rHLPD) to do this. Solidia Cement is intended to be a sustainable replacement for Ordinary Portland Cement (OPC). It uses the same manufacturing process, equipment and raw materials used by the cement industry while consuming less energy and generating less greenhouse gases.
Oficemen releases CO2 emission reduction roadmap
19 October 2017Spain: Oficemen, the Spanish cement association, has released its roadmap for reducing CO2 emissions to 2050. The document highlights the potential of new technologies, including carbon capture and storage (CCS), which could decrease the CO2 footprint of the Spanish cement industry by up to 80% in 2050. Using existing the technology the association estimates it could reduce emissions by 35% from a 1990 baseline.
Germany: Bernd Scheifele, the chairman of HeidelbergCement, has admitted that his company needs to take action to improve its overall sustainability management following its acquisition of Italcementi. Following the purchase both its specific gross CO2 emissions per tonne of cementitious material and its alternative fuels mix fell. However, specific emissions of NOx and SOx fell, although specific dust emissions rose in the reporting period. The cement producer also improved accident frequency despite increasing its workforce to 15,781 in 2016 from 9560 in 2015.
Central Pollution Control Board orders three cement plants to cease operation in Telangana
23 June 2017India: The Central Pollution Control Board (CPCB) has ordered three cement plants to stop operation and issued show-cause notices to 11 other units in Telangana. Kakatiya Cements in Nalgonda, Mancherial Cements in Mancherial and the government owned Cement Corporation of India at Tandur have been issued with closure notices, according to the new Indian Express newspaper. Around 240 cement factories across the country have been sent either closure or show-cause notices.
The campaign follows an initiative asking selected industries to install online pollution monitoring systems which are to be connected to the CPCB as well as State Pollution Control Board servers to ensure real-time monitoring of pollution emission of industries. Cement plants have also been sent show-cause notices for failing to meet new emissions standards set by the CPCB.
Cement Sustainability Initiative publishes technology review on mitigating CO2 emissions
22 June 2017Switzerland: The Cement Sustainability Initiative (CSI) has published a technology review on current and anticipated developments that can be used to mitigate CO2 emissions in cement production. The report includes 52 individual papers on existing technologies and seven additional summary papers
The CSI initiated a review of its original technology papers, which were originally developed in 2009, when the sector issued the first ever low-carbon technology roadmap in partnership with the International Energy Agency (IEA), following the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement. The European Cement Research Academy (ECRA) and a stakeholder consultant processes have also supported the project.
Key technological fields covered in the current review include: thermal energy efficiency, electric energy efficiency, use of alternative fuels, materials and biomass, reduction of the clinker content in cement, new binding materials, CO2 capture and storage (CCS), and CO2 use (CCU). The report also includes an assessment of the level of possible implementation, the challenges and costs of these technologies in future scenarios for 2030 and 2050.
“The publication of these revised and new technical papers sets robust foundations for the overall exercise of updating our 2009 roadmap. It is also a major step in the implementation of commitments made by the cement sector in Paris through the Cement Low Carbon Technology Partnerships initiative (LCTPi) and it demonstrates that the business is more than ever focused on supporting the implementation of the Paris Agreement,” said Philippe Fonta, managing director of the CSI.
The CSI and IEA plan to share the initial results of the updated global technology roadmap for the cement sector at COP 23 in Bonn, Germany.
