Building new buildings from old ones
19 April 2023Holcim launched its formal take on construction and demolition waste (CDW) this week with the unveiling of its ECOCycle technology platform at the BAU architecture fair in Munich. This amounts to managing the distribution, processing, grinding and recycling of CDW back into new building material products. It claims that its concrete, cement and aggregate products can contain 10 - 100% of CDW with no drop in performance.
It is hard to gauge whether this is marketing for existing operations or the start of something new. Yet, in its 2022 Sustainability Report, Holcim said that it recycled 6.8Mt of CDW back into building products and that it is on track to meet its target of 10Mt by 2025. This target was neatly put into words as wanting “to build more new buildings from old ones.” Ahead of the announcement of the launch of ECOCycle, it added that it was going to roll out its Susteno product around Europe. This product, made from 20% CDW, was originally released in Switzerland in the late 2010s. Notably, recent acquisitions by Holcim that connect to its growing focus on CDW include Poland-based Ol-Trans in July 2022, UK-based Wiltshire Heavy Building Materials in October 2022 and UK-based Sivyer Logistics in April 2023.
As covered by Global Cement Weekly in February 2023, Holcim is not the only heavy building materials company pivoting to CDW. The European Union (EU) set a 70% recovery target for it in 2020 and various cement company sustainability reports have described the region as being receptive to moves into this sector. Cemex set up a global waste management subsidiary called Regenera at the end of January 2023. This division covers both alternative fuels, CDW and industrial by-products, so it is more general than Holcim’s current effort, but it shows intent in the same direction. Cemex previously set a target of recycling 14Mt/yr CDW by 2030.
Heidelberg Materials has been working on developing recycled concrete paste and its ReConcrete-360° concrete recycling process. As of its last sustainability report, this process had been tested at the pilot scale and is now being developed and scaled for industrial application. In addition to acquiring UK-based Mick George Group in December 2022 Heidelberg Materials has also purchased Germany-based RWG Holding in January 2023 and Germany-based SER Group in February 2023. All three companies operate in the CDW sector.
The other notable contribution that Heidelberg Materials has been making is as a partner of the ‘Circular City - Building Material Registry for the City of Heidelberg’ project. When Heidelberg Materials announced its involvement in the initiative in mid-2022 it said it was the first city in Europe to apply the principles of urban mining. The goal of the project is to take an inventory of the city’s buildings and then compile it in a digital material registry. The basis for the registry is the Urban Mining Screener developed by EPEA (Environmental Protection Encouragement Agency). This programme can estimate the composition of buildings based on building data such as location, year of construction, building volume or building type. Circular economy supply chains can then act accordingly when a building is retrofitted, demolished or deconstructed. So, for example, at the start of the project it worked out that a former US Army housing estate conversion site was calculated to contain approximately 466,000t of material, with about half in the form of concrete, a fifth in the form of bricks and 5% as metal.
That last example compares to a European Commission estimate that, as a whole, Europe generates around 450 - 500Mt/yr of CDW. A third of this is concrete. As with alternative fuels and slag previously, this may be money going into the ground. Recycling building materials is not new but any significant increase in reusing CDW that can reduce the clinker factor of cement (and the cement factor of concrete) offers a potentially cheaper route to building materials decarbonisation than carbon capture and utilisation/storage at current costs. Hence the continued interest.
Cemex Philippines halves CO2 emissions since 1990
18 April 2023Philippines: Cemex Philippines (CHP) says it has reduced the CO2 emissions from its subsidiaries, Solid Cement Corporation and APO Cement Corporation, by 50% between 1990 and 2022. From 2020 to 2022 CHP reduced its net CO2 emissions by 18%. The company claims this is the highest CO2 emissions reduction in the sector based on publicly released information.
Luis Franco, the president and chief executive officer of CHP, said "This milestone CO2 reduction was possible because of our team's high commitment to achieve net zero. We are on track to meet our ambition of less than 430kg of net CO2 per tonne of cement by 2030 and deliver net-zero CO2 concrete by 2050." He added that the company is confident it can reach a 67% reduction by 2030 through the continued used of alternative fuels and decarbonated raw materials.
Switzerland: Holcim has appointed Rodolfo Vargas Pedroza as Group Expert Geology. He previously worked as Group Lead Geology for the company from 2018. He has worked for Holcim Group since 2018 and other prior positions include Lead Geologist and Senior Mining Engineer. Before this he was the Head of Geology and Mining for Cemex from 2001 to 2011 and the Geology and Mining Manager for Cemex Colombia in the late 1990s. Vargas Pedroza is a graduate in geology from the Universidad Nacional de Colombia.
Colombia: A criminal court has found former Cemex Colombia vice president Édgar Ramírez Martínez and fellow former director Eugenio Correa Díaz guilty of fraud, according to El Espactador newspaper. The court found that Ramírez Martínez had committed unfair administration, illicit enrichment and falsification of a private document in the process of obtaining land for use as a quarry to supply its Maceo cement plant in Antioquia. It found that Correa Díaz had committed illicit enrichment, money laundering and falsification of a private document while serving as an intermediary in the same process. Ramírez Martínez received a prison sentence of 15 years and one month, while Correa Díaz received a sentence of 20 years.
Cemex Colombia obtained the land in question during the administration of the estate of deceased embezzler José Aldemar Moncada. The court found that it had defrauded the true owners, a local family, in order to include it in Moncada's asset forfeiture prior to sale to Cemex Colombia by Correa Díaz.
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.
Mexico: President Andrés Manuel López Obrador has accused the US government of funding environmentalists' challenges to the government's planned Tren Maya tourist railway project. AP News has reported that López Obrador has declared the project a matter of national security.
Cemex is currently embroiled in a dispute with Vulcan Materials subsidiary Sac-Tun over use of the latter's Punta Venado terminal in Quintana Roo. The terminal sits along the planned route of the Tren Maya line. The Mexican State Prosecutor's Office supported Cemex's re-entry into the terminal on 14 March 2023. The government previously rejected Sac-Tun's application to renew its quarrying licence for its quarry at the site of the terminal.

Update on Mexico, March 2023
22 March 2023A dispute between Cemex and Vulcan Materials over the use of a terminal in Quintana Roo state heated up this week as the two companies publicly argued over the situation. US-based Vulcan Materials went to the press to say that the Mexican police had forced entry into the facility south of Cancun, run by its subsidiary Calica, with orders to allow a Cemex ship to discharge cement. Vulcan denied that the authorities had any legal basis for the action and said that it was an illegal occupation. Cemex then responded with a press release explaining that the two companies had held a previous contractual relationship for joint-usage of the terminal until the agreement broke down in late 2022. It says it was granted an injunction by a local court to continue using the terminal while legal proceedings carry on.
The disagreement over the use of the Punta Venado terminal dates back to at least 2018 when Vulcan initiated a North American Free Trade Agreement (NAFTA) arbitration claim over alleged planning and environmental issues in relation to a nearby quarry. Dialogue continued, but Calica’s operations in the area were shut down by the government in May 2022. Subsequently, Vulcan’s total volumes of shipped aggregates fell by 6% year-on-year to 54Mt in the fourth quarter of 2022, partly due to the closure.
Unfortunately, the argument has become increasingly politicised with Mexican president Andres Manuel Lopez Obrador criticising Vulcan for its environmental record and US senators using the Vulcan case as an alleged example of Mexico treating US companies unfairly. Some media commentators have also noted that the Mexican government is promoting a number of large-scale infrastructure schemes in the region, including the Tren Maya project, a new 1500km train line around the Yucatan peninsula, which would link tourist towns such as Cancún with historical sites like Palenque.

Data from the National Institute of Statistics and Geography (INEGI) shows that rolling annual cement production in Mexico peaked at around 43Mt in late 2018 before falling to 39Mt in mid-2020. It later recovered to a peak of just under 46Mt in mid-2021. It has since dropped a little to mid-2022 and then started to trend upwards again. The nominal cement production capacity in Mexico is 60Mt/yr according to the Global Cement Directory 2023. Yet, the actual production capacity has been reported in local press as being 42Mt/yr, lower than the annual cement production of 43.9Mt in 2022. In February 2023 it was reported that the Mexican government was taking steps to 'implement import facilities' to support more cement being imported. This was due to shortages in certain states particular in the south-west of the country.
Cemex’s net sales in Mexico grew by 11% to US$3.84bn in 2022 and this was attributed partly to tourism-related construction in ‘the peninsulas.’ Holcim noted ‘market softness’ for cement in the country but reported growth for concrete due to infrastructure projects such as the Tren Maya. Cemento Moctezuma’s net sales rose by 2.6% to US$878m. Despite rising sales, both Cemex and Cemento Moctezuma reported falling earnings in 2022.
The dispute between Cemex and Vulcan Materials overlaps with wider trends on how and where the Mexican cement market is developing following a lull in the late 2010s. Production is growing in certain parts of the country, particularly in the Yucatan peninsula due to various infrastructure projects and tourism-related demand. However, the overall economic environment appears to have decreased earnings for some producers. However Cemex said that this was starting to correct itself in late 2022, as prices caught up with inflation. Portraying the Cemex - Vulcan situation in nationalistic terms is unhelpful, especially since Cemex made more money in the US than Mexico in 2022! However, this may be yet another example of more isolationist economic policies along the same lines as the US Inflation Reduction Act.
Cemex explains right to use Punta Venado terminal
21 March 2023Mexico: Cemex says that it is within its rights to have continued using the Punta Venado terminal in Quintana Roo beyond the expiry of its contract with owner Sac-Tun at the end of 2022. Cemex says that it obtained an injunction to continue using the facilities after it began to have difficulty accessing them in late 2022. It subsequently obtained a contempt of court order against Sac-Tun when it tried to prevent it from accessing the terminal.
The Mexican State Prosecutor's Office supported Cemex's re-entry into the Punta Venado terminal on 14 March 2023.
Mexico: US-based Vulcan Materials has accused Cemex of illegally entering and unloading materials at its Punta Venado terminal in Quintana Roo. Vulcan Materials' subsidiary Sac-Tun operates the terminal, which serves its nearby Playa del Carmen quarry. Sac-Tun previously provided handling and unloading services at the terminal for Cemex, under a contract which expired on 31 December 2022. A local court ruled in favour of Cemex in the dispute over its continued use of the facilities on 5 March 2023. A high court intervened with an injunction in favour of Vulcan Materials on 16 March 2023.
Vulcan Materials now plans to take further legal action, according to Forbes. It is currently engaged in another legal dispute against the Mexican government for the latter's refusal to renew Sac-Tun's licence to operate the Playa del Carmen quarry. The producer is seeking damages of US$78.9m. The government said that the quarry had ceased to operate in line with requirements under its environmental impact licence and local land use plans.
Cemex launches new logo
15 March 2023Mexico: Cemex has updated its logo to a new design, which it says presents a ‘fresher, closer, and more dynamic’ visual identity. The groups says that this signifies a ‘clear and decisive company transformation.’
CEO Fernando González said “I am excited to present the renewed image of our company. But what excites me most is what is behind the change: a renewed commitment to helping our customers push the boundaries of sustainable construction through innovative solutions.”
