Mexico: Cemex has adopted the United Nations (UN) Sustainable Development Goals (SDG). It has prioritised five goals from the charter that connect with the company’s business and represent an opportunity to contribute to the UN 2030 Agenda. These five goals are focused on the promotion of decent employment and economic growth (SDG 8), innovation and infrastructure development (SDG 9), climate change mitigation (SDG 13), environmental and ecosystem conservation (SDG 15) and the advancement of sustainable cities and communities (SDG 11). Cemex plans to continue embedding the UN SDGs into its business processes to create systemic change, increase engagement, promote a sense of purpose and raise awareness among its stakeholders.
Cement industry takes emissions seriously
22 May 2019Today is the first day of the Global FutureCem Conference taking place in Brussels, Belgium. The event is looking at how the cement industry can adapt to a low or zero carbon world. Although Global Cement is organising the event, it is clearly topical as two news stories this week demonstrate.
Firstly, the chief executive officers (CEO) from 13 US companies, including LarfargeHolcim, announced that they were lobbying the US government to enact business-led climate change legislation. The initiative, known as the CEO Climate Dialogue, included principles such as ‘significantly’ reducing US greenhouse gas emissions. This is shocking because, at face value, large-scale CO2 emitters like LafargeHolcim have the most to lose from more rigorous environmental regulations. What do they have to gain from doing this? This is like turkeys voting for Christmas!
Interpretations of why LafargeHolcim and others might want to do this could go in a few directions. Firstly, the intention might be fully plausible. These companies could genuinely want to combat climate change. Secondly, more cynically perhaps, leading demands for legislation puts the lobbyists in the room when change is actually made. Given the integral nature of concrete in modern construction this is not necessarily a bad thing. Environmentalists may want to ban building materials that create CO2 emissions but, until they can offer an alternative or convince people to accept reduced quality of life, then cement is the material of choice. Thirdly, leading change allows one to stay ahead of it or at least give the sector more time to react to it. The ‘turkeys’ may not want to vote for ‘Christmas,’ but perhaps ‘Christmas’ could be replaced with something else?
This latest initiative by the CEOs in the US has parallels with the creation of the Global Cement and Concrete Association (GCCA) in 2018. Like the current moves in the US, cement producers led the creation of the GCCA, to promote concrete as the sustainable building material of choice.
Meanwhile, Germany’s HeidelbergCement also announced this week that its CO2 reduction targets to 2030 have been assessed against the Science Based Targets initiative’s (SBTi) criteria. Its SBTi target is to reduce scope 1 greenhouse gas (GHG) emissions 15% per ton of cementitious material by 2030 from a 2016 base year. HeidelbergCement has also committed to reduce scope 2 GHG emissions by 65% per ton of cementitious materials within the same timeframe. The SBTi target follows HeidelbergCement’s previous goal of a 30% reduction in its specific net CO2 emissions by 2030 compared with 1990. It says it has achieved a reduction of 20% so far.
HeidelbergCement is a sustainability leader in the sector with various projects on the go including the Low Emissions Intensity Lime And Cement (LEILAC) consortium direct separation pilot project at the Lixhe cement plant in Belgium. Following SBTi is a continuation of this trend, albeit one that anchors it with a global consensus.
Coincidence perhaps but when the two largest non-Chinese cement producers start announcing sustainability stories like then the picture is changing. The questions at this point is how far will it go.
A full review of the 3rd Global FutureCem Conference will be published after the event. To find it and more information visit: http://www.globalcement.com/conferences/global-future-cement/introduction
US: The chief executive officers (CEO) of 13 US companies, including LarfargeHolcim, are lobbying the President and Congress to enact business-led climate change legislation. This initiative, known as the CEO Climate Dialogue, urges the government to put in place a long-term federal policy as soon as possible, in accordance with a set of six guiding principles. The group aims to build bipartisan support for climate policies that it says will, “… increase regulatory and business certainty, reduce climate risk, and spur investment and innovation needed to meet science-based emissions reduction targets.”
Companies involved in the CEO Dialogue include BASF, BP, Citi, Dominion Energy, Dow, DTE Energy, DuPont, Exelon, Ford Motor Company, LafargeHolcim, PG&E, Shell, and Unilever. Four environmental groups have also supplied input to the initiative. These are the Center for Climate and Energy Solutions, Environmental Defense Fund, the Nature Conservancy and World Resources Institute.
The six principles include: ‘significantly’ reducing US greenhouse gas emissions; allowing an effective timeline for reductions that will help capital intensive industries to adjust in an ‘economically rational manner’; instituting a market-based price on carbon; making the policies durable and responsible; doing no harm to the competitiveness of the US economy with particular attention to carbon leakage; and promoting equity. Specifically the initiative says that US policy should ensure the country is on a path to achieve economy-wide emissions reductions of 80% or more by 2050 with ‘aggressive’ short and medium term emissions reductions.
“Tackling the challenge of climate change is no easy task, and as industry leaders, we have an opportunity to join forces to advocate for climate legislation. It is critical we begin to set durable and achievable goals that help safeguard the environment while reducing our carbon footprint,” said Jamie Gentoso, the CEO for US Cement operations of LafargeHolcim.
Germany: HeidelbergCement’s CO2 reduction targets to 2030 have been successfully assessed against the Science Based Targets initiative’s (SBTi) criteria. It says this makes it the first company in the cement sector to have approved science-based targets.
"Our goal is to realise the vision of CO2-neutral concrete by 2050 at the latest. In the coming years, we want to make significant progress in this direction, and the SBTi’s approval is a clear proof of our strong commitment," said Bernd Scheifele, the chairman of the managing board of HeidelbergCement. The group’s CO2 reduction strategy is based on measures on plant and product level. These include improving energy efficiency, and a steadily increasing use of alternative fuels and alternative raw materials.
HeidelbergCement’s SBTi target is to reduce scope 1 greenhouse gas (GHG) emissions 15% per ton of cementitious materials by 2030 from a 2016 base year. HeidelbergCement also commits to reduce scope 2 GHG emissions 65% per ton of cementitious materials within the same timeframe. The SBTi target is consistent with HeidelbergCement’s previous goal of a 30% reduction in its specific net CO2 emissions by 2030, compared with 1990. The cement and concrete producer has achieved a reduction of 20% so far.
The SBTi assesses and validates corporate emissions reduction targets against climate science research. Targets adopted by companies to reduce greenhouse gas (GHG) emissions are considered ‘science-based’ if they are in line with the goals of the Paris Agreement – to limit global warming to below 2°C above pre-industrial levels and pursue efforts to limit warming to 1.5°C.
Switzerland: LafargeHolcim reduced its net CO2 emissions per tonne of cementitious material by 1% year-on-year to 576kg CO2/t in 2018 from 582kg CO2/t in 2017. It said that the improvement was achieved by reducing the clinker-to-cement ratio and consuming less energy per tonne of cement, mostly by using alternative fuels and improving the efficiency of the company’s processes. However, data from its Sustainability Report 2018 shows that both its overall gross and net emissions grew. Its net CO2 emissions from cementitious material increased by 2.5% to 121Mt. At the same time its clinker production rose by 2.7% to 151Mt from 147Mt.
The group increased its treatment of waste-derived resources to 52Mt. its alternative raw material substitute rate grew to 11.2% from 10.7%. It established a new pre-processing facility in Madukkarai in India and upgraded its waste handling capacities in Mexico, Ecuador, Brazil, Argentina, the Czech Republic, Bulgaria, India, Canada, Spain and Germany. It also reduced its freshwater withdrawal for cement production and improved its lost time injury rates.
When China sneezes...
01 May 2019RHI Magnesita has taken the step this week of raising its prices globally by 5% for its products for its industrial and steel divisions. It has applied the increase to both its basic (magnesia and dolomite based) and non-basic products, varying in a range of 3% to 20%. It has blamed this on a global scarcity of raw materials caused mostly by Chinese environmental regulations on mining and processing. It goes on to attribute the issue to increased export taxes, more restrictive allocation of explosives and the nationalisation or controlled consolidation of mining operations in China. All of this has, “...structurally altered the production, pricing and dynamics for industrial minerals.”

Other major refractory producers, including Imerys and Vesuvius, reported similar mounting raw material costs in 2018. They also implemented price changes to maintain income and/or sales growth. As can partly be seen in Graph 1 some of the major refractory producers reported mixed fortunes in 2018 for their divisions that produce products for the cement industry.
RHI Magnesita noted that 2018 was a year of steady refractory market growth and relative stability for cement and lime from a global market perspective, with some significant variances on a regional basis. Imery’s Energy Solutions & Specialties division suffered due to flat markets. However, its High Resistance Materials division (not shown in Graph 1) benefited from the ongoing integration of Kerneos into the group. The group restructured its businesses at the end of 2018 creating a High Temperature Materials & Solution segment that brings together its various refractory concerns. Vesuvius' Steel Advanced Refractories division, which include monolithic products, reported particular growth in the Americas in 2018. Although it noted some market share loss in North Asia and in certain European countries, the latter due in price increases.
Refractories aren’t the only material or commodity used by the cement industry that has been distorted by Chinese domestic policy. Regulations on imports of waste streams including plastics started in 2017 leading to European and US suppliers struggling to find alternate markets. One implications of this appears to have been waste firms focusing on separating plastic into high and low calorific fractions to fight the downward price trends of a market glut. The outcomes are different but the sheer size and variety of China’s economy is increasingly affecting the cement industry in new and different ways.
RHI Magnesita’s travails in China and the debacle of waste imports bring to mind the quote by the 19th century Austrian diplomat Klemens von Metternic, ‘When Paris sneezes, Europe catches a cold.’ Metternic was referring to Napoleonic-era France and its aftermath. The modern version may have been used to reference the US but maybe it should be instead, ‘When China sneezes, the world catches a cold.’ Gesundheit.
Argentina: Loma Negra and tyre manufacturer Bridgestone have started a partnership to re-use water in the Llavallol suburb of Buenos Aires. Bridgestone will provide Loma Negra with 200,000l/days of filtered water for use at its operations, according to the Mercado newspaper. In return Loma Negra will use less water from the local aquifer.
UK: The Global Cement and Concrete Association (GCCA) is formally joining the Concrete Sustainability Council (CSC). By doing so it is adding its support to the only world-wide industry specific system that certifies the sustainability performance of concrete plants and their supply chain across the globe. Developed in conjunction with social and environmental stakeholders, the CSC is the industry recognised authentication system, with more than 160 plants certified to its standards across eight different countries.
“We are delighted at the decision of the GCCA to champion the many sustainability benefits of concrete by putting their global reach behind the CSC. We look forward to reinforcing and accelerating our work with their support,” said CSC chairman, Christian Artelt.
Clients, developers and contractors can be assured of socially and environmentally responsible practices through the concrete supply chain when specifying CSC certified concrete. Internationally recognised sustainable project assessment methods such as BREEAM and DGNB credit design teams and their projects with points when CSC certified concrete is specified and procured.
SNIC launches Cement Technology Roadmap for Brazil
11 April 2019Brazil: The National Union of Cement Industry (SNIC) and the Brazilian Portland Cement Association (ABCP) have launched a Cement Technology Roadmap to 2050. SNIC president Paulo Camillo Penna said that the document would help the local industry cut its carbon footprint in the medium and long term. The roadmap was developed with the International Energy Agency (IEA), the Cement Sustainability Initiative (CSI) of the World Business Council for Sustainable Development (WBCSD), the International Finance Corporation (IFC) of the World Bank and a group of academics led by José Goldemberg.
The roadmap intends to reduce specific CO2 emissions by over 30% to 375kg CO2/t of cement in 2050. Key actions to 2030 include strengthening national and international cooperation, promoting new cement standards, raising the clinker substitution rate, promoting the use of alternative fuels in compliance with the National Policy on Solid Waste (PNRS), sharing best practive in energy efficiency and promoting resaerch and development in new greenohuse has mitigation technologies.
US: The Portland Cement Association (PCA) has announced the winners of the 2019 Energy and Environment (E&E) Awards. The awards recognised environmental and community relations projects that were completed in 2018 and were presented at the 3rd Annual Cement and Concrete Fly-In.
The CalPortland Mojave cement plant in California won the Energy Efficiency award for the installation of a new classifier system for its vertical roller mill that increased energy efficiency by reducing fan power requirements. The plant also installed a control system for the finish mill that will maximise performance and help reduce wear on equipment. The classifier installation reduced the finish mill energy intensity by 1.5 to 2.0kWh/t, and the control system reduced energy intensity by 13%. In 2018 22% of the electricity consumed by the plant came from on-site renewable wind energy generation. CalPortland has implemented significant energy efficiency measures and its energy management program has been recognised by the Environmental Protection Agency Energy Star program as the Energy Star Partner of the Year for 15 years in a row.
Roanoke Cement Company and Titan America’s Troutville plant in Virginia won the Environmental Performance award for being the first cement manufacturing plant in the US to receive ISO 50001 certification for energy management of all aspects of energy procurement, design and use. The plant reduced its total electrical consumption by 10% and fossil fuels use by more than 12%. The plant has also implemented an alternative fuels program as part of its certification for the True Zero Waste Program, administered by Green Business Certification and has received silver status achieving a 96% rate of waste divergence from landfills.
Lehigh Hanson’s Permanente cement plant at Cupertino in California won the Innovation award for the installation of a water treatment system reducing concentrations of metals, including selenium, to meet permit limits. Lehigh Hanson developed a treatment system that combined ultrafiltration and reverse osmosis (UF/RO) technology in conjunction with biological treatment technology to remove metals, including selenium and dissolved solids. This ensured applicable effluent limits were met while optimising treatment capacity and efficiency. This treatment system is the first of its kind in the cement industry ensuring that effluent limits are met while, at the same time, limiting the quantity of waste needed to be managed.
Buzzi Unicem USA’s Greencastle cement plant in Indiana won the Land Stewardship award for opening a 4km smooth packed stone trail in conjunction with the not-for-profit People Pathways organisation as Phase 2 of the Putnam Nature Trail. Buzzi Unicem USA staff and People Pathways used heavy equipment for rough clearing and grading of the overgrown former railroad bed and improved and expanded the physical trail. These areas were then landscaped with trees, native prairie vegetation plugs, interpretive signage, benches, birdhouses and other features. Additional nature trail enhancements include placement of wildlife monitoring cameras along the trail, installation of nesting boxes and interpretive signage, and maintenance of the recently completed restoration of native flora installed in 2017 and 2018.
Cemex’s Lyons cement plant in Colorado won the Outreach award for volunteering work by its staff at the Rocky Mountain National Park in Boulder, Colorado, performing campground improvement activities at Glacier Basin Campground by moving rocks and fallen timber and clearing existing fire pits of ash deposits. The plant then introduced a new community outreach initiative by hosting a Manufacturing Day event, providing local students tours of the quarry and plant to increase youth interest in pursuing a vocation in skilled trades. Additionally, the plant teamed up with the Celestial Seasonings B Strong Ride for cancer care and research for an event aimed at increasing safety awareness while fundraising for two local organizations and their efforts to fight cancer.
