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.

Before this he worked for ACC in logistics and shipping positions. Garg is a graduate of the Indian Institute of Management in Calcutta and the Indian Institute of Technology in Kharagpur.
Portugal: The first batch of clinker has been manufactured on the new upgraded production line at Secil’s Outão plant. Construction and start-up teams from ThyssenKrupp Polysius reached the milestone in mid-April 2023 after a heating period of 72 hours. Germany-based ThyssenKrupp Industrial Solutions was appointed by Secil to work on the Clean Cement Line project in 2020. It said it was going to modify the existing rotary kiln and preheater tower, install a new calciner and add a new grate cooler. Once finished it will produce Portland limestone cement (PLC). It is scheduled for commissioning in mid-2023.
Italy-based CTP Team was contracted in mid-2020 to supply and install a 29MW waste heat recovery (WHR) unit for the project. It planned to use an organic rankine cycle (ORC) unit using a 7.2MW turbine supplied by Turboden.
Italy-based Bedeschi also revealed in early April 2023 that it was in the cold commissioning phase for a new pipe conveyor at the plant to handle different kinds of alternative fuels. The conveyor has a diameter of 250mm and conveying length of 350m and will transport alternative fuels at a rate of 300m3/hr.
Cash flow issues noted in Vietnamese cement sector
19 April 2023Vietnam: Cash flow issues have been noted as a risk for local cement producers struggling to create enough revenue to continue operations. Revenue is reliant on output, local consumption and exports but these are all falling with raw material costs rising and no improvement forecast for the real estate in the short-term, according to the Việt Nam News newspaper. Examples of cement companies reporting a loss include Quang Ninh Construction and Cement in the fourth quarter of 2022. An estimate by the Quang Ninh Tax Department also showed that the company owed more than US$4.m in July 2021, making it the largest debtor in the province’s building materials industry. Quang Son Cement, based in Thanh Hoa province, also reported an after-tax loss of US$13.5m in 2022.
Data from the Vietnam Association for Building Materials (VABM) shows that the cement industry’s production capacity reached 114Mt/yr in 2022, with an estimated output of 93Mt in 2022, giving it a capacity utilisation rate of 82%. However, domestic consumption accounts for around 60 –65Mt/yr, with exports accounting for the remainder. Information from the General Statistics Office reveal that local cement production fell by just under 10% year-on-year in the first quarter of 2023.
Thai Duy Sam, vice president and general secretary of VABM, told Vietnam Investment Review “In recent years, the cost of input materials, particularly coal, has increased multiple times. It has an effect on both production and output.” He added, “Currently, several significant corporations continue to ensure production. However, small enterprises with production lines that can produce 1 - 2t/day face both manufacturing and consumption challenges.” He continued by saying that the production lines of older plants have high depreciation costs and greater heat and electricity consumption than modern units. In addition, these smaller and older plants often lack a trademark, which can make the sales process harder. Commenting on the real estate market, Sam noted complicated payment processes can cause problems with both construction companies and building material suppliers. He cited examples of how the payment for the building materials used to build the Dong Tru and Vinh Tuy bridges had still not been settled 10 years after completion.
Nigerian cement producers among group of manufacturers that spent around a quarter of revenue on raw materials in 2022
19 April 2023Nigeria: Raw material costs for a group of major local manufacturers – including BUA Cement, Dangote Cement and Lafarge Africa – accounted for 24% of revenue in 2022. The increase in the cost of raw materials was driven by a shortage of foreign currency, raw material availability, logistics issues at ports and rising energy costs, according to the This Day newspaper. BUA Cement’s spending on raw materials rose by 9% year-on-year to US$54.3m in 2022, Dangote Cement’s spend grew by 12% to US$427m and Lafarge Africa’s expenditure increased by 32% to US$106m. The other companies included as part of the grouping included BUA Foods, Nestlé Nigeria, Cadbury Nigeria, Nigerian Breweries and Dangote Sugar Refinery.
Malaysia: Prime Minister Anwar Ibrahim says that a ‘reasonable’ cement price will be offered to housing developers that develop affordable projects. The initiative is targeted at the Bottom 40% (B40) and Middle 40% (M40) income groups, according to the Bernama news agency. The government is working with the Malaysian Cement and Concrete Association (C&CA) and private housing developers to offer the reduced cement price. US$27m will be provided to back the incentive. 1Mt of cement will be made available at a subsidised discount of 29% under the Rahmah Cement Scheme Initiative.
Anwar Ibrahim said “This private incentive is adequate for the construction of up to 24,000 units of affordable houses.” It is part of the coalition government’s ambition to increase the supply of affordable housing.
Germany: Robert Habeck, the Federal Minister for Economic Affairs and Climate Action, has visited specialist Flender at the Hannover Messe trade fair. He spoke with the company’s head Andreas Evertz about the energy transition goals for Germany and Europe, Flender's role as a supplier for the wind sector, and the importance of an energy-efficient industry on the way to reach global climate goals. The mechanical drive manufacturer was part of the government minister’s official tour of the exhibition.
Habeck said, "Discussing about the expansion of renewable energies, we usually talk about the electrical output, the production. But here at Hannover Messe, we see also the other side of the coin. A lot of the industrial production is here in Germany, or at least with German companies. And when you say the market is now swinging in and growing, that's good news." He added that “It is challenging to bring electricity production out of renewables to 80% of the demand by 2030, but it is possible."
Evertz said "Flender is a major driver of the energy transition. And this starts with any kind of materials. In drive technology, Flender not only manufactures wind gearboxes, but industrial gearboxes that are involved in the production of raw materials for wind turbines. Flender is part of nearly every supply chain."
Other recent interest shown by the German government include a tour by Foreign Minister Annalena Baerbock of Flender’s plant in Tianjin as part of a tour of China.
