Dalmia Cement (Bharat) deploys gas-fuelled truck fleet
20 February 2023India: Dalmia Cement (Bharat) has successfully launched its new fleet of 35 liquefied natural gas (LNG)-fuelled trucks from its Murli cement plant in Maharashtra. The trucks are of two types, covering ranges of 50 - 600km, and will transport bagged cement and bulk raw materials. They have 28% lower CO2 emissions than conventional diesel-powered trucks, and are thus able to eliminate 840t/yr of CO2 emissions, while also reducing emissions of nitrous oxides (NOx) by 59% and particulates by 91%, and eliminating emissions of sulphur oxides (SOx).
Dalmia Cement (Bharat) says that its next move will be to launch a second fleet of 25 trucks from its Ariyalapur cement plant in Tamil Nadu. By April 2024, it plans to convert 10% of its 3000 truck-strong fleet to LNG fuel.
A spokesperson for the company said “Dalmia Cement has been following the business philosophy of Clean & Green is Profitable and Sustainable. Our overall CO2 emissions have come down from 670kg/t to 467kg/t – one of the lowest globally – and we are focusing on realising our carbon negative goal by 2040. We are delighted to partner with GreenLine Logistics for further reduction of our Scope 3 greenhouse gas emissions.”
South/Central America: Holcim Latinoamérica says that it expects to use 18% renewable power across its operations in February 2023, compared to 8% throughout 2022. The regional unit of Holcim says that it will increase its share of renewable power to 25% by the end of 2023. It is committed to a target of 60% renewables by 2030. Holcim Latinoamérica's operations span Argentina, Colombia, Costa Rica, Ecuador, El Salvador, Nicaragua and Mexico.
Earlier in February 2023, Holcim Nicaragua commenced construction of a 3.38MW solar power plant in Nagarote, León Department. The producer said that the solar power plant's contribution to the national grid will cover 40% of its consumption in its cement operations there.
Holcim's Latin America regional head Oliver Osswald said “Our world is in constant change from population growth, urbanisation and the climate challenge. That is why, at Holcim, we are determined to put our best foot forward to accelerate low carbon circular construction."
Holcim to acquire Duro-Last
07 February 2023US: Holcim has signed an agreement with Duro-Last to acquire the roofing systems producer for US$1.29bn. Reuters has reported that the acquisition will be Holcim's largest for all of 2022 and 2023 so far. Once the parties complete the transaction, Duro-Last's business will join Holcim's products and systems division. Holcim expects the deal to yield synergies of US$60m/yr, primarily through a reduction in the cost of materials.
Holcim expects its products and systems division to contribute a majority of its profit in North America once increased investment under the US government's Inflation Reduction Act begins to take effect. In 2022, the division accounted for 40% of regional profit. The group is committed to a global target of 30% of sales being attributable to the products and systems division by 2025, compared to 19% of sales in 2022.
Mexico: GCC has secured validation by the Science-Based Targets Initiative (SBTI) for its latest CO2 reduction goals. The group has committed to reducing its Scope 1 emissions per tonne of cementitious product by 31% and its Scope 2 emissions per tonne of cementitious product by 57% between 2015 and 2030. It has also committed to a 37.5% absolute reduction in its products’ Scope 3 emissions over the same period. The goals will serve as sustainability performance targets for GCC’s US$500m sustainability-linked bond, which it issued in January 2022.
GCC's vice president of sustainability and environment Gina Lotito said "We are proud and excited to be a catalyst of progress towards a low-carbon future. Our laser-focus on our climate change strategy and emphasis on reducing CO2 emissions is a testament to our commitment to creating a sustainable future. While we celebrate our achievements, we acknowledge that there is still much work to be done and remain steadfast in our mission."
Update on construction and demolition waste, February 2023
01 February 2023Cemex launched a new waste management division called Regenera this week. Cemex describes Regenera as a “business that provides circularity solutions, including reception, management, recycling, and coprocessing of waste.” The Mexico-based company has a long and leading history with sourcing and using alternative fuels in the cement sector and the new organisation looks set to utilise this experience. What is notable though is how the business is targeting three waste streams: municipal and industrial; industrial by-products; and construction, demolition and excavation waste (CDEW). Bringing the three waste streams together in this way appears to be novel for the heavy building materials sector, particularly the inclusion of CDEW, which we will explore further here.
CDEW is split into fractions, just like the municipal and solid waste streams that end up as alternative fuels at cement plants, but the biggest fractions are generally concrete, followed by bricks. The recycled concrete is then typically used as an aggregate, either in new concrete production or in areas like road construction and earthworks. The use of recycled aggregates (RA) made from CDEW goes back to at least the 1930s in its current form although ‘reusing’ materials from structures such as castles and churches goes back far further. Recycling and reusing CDEW gained a boost in 2020 when the European Union (EU) set a 70% recovery target. However, within the EU the CDEW recycling rates vary considerably and that 2020 target includes the use of CDEW in backfill applications.
In its launch statement for Regenera, Cemex noted that it operates a dock in Paris, where it receives a variety of materials, including construction debris, excavated material and inert soil. These materials are sorted, processed and then transformed into recycled aggregates or organic material used to restore quarries. Cemex then promptly followed up the official launch of Regenera on 30 January 2023 with the acquisition of a majority stake in Shtang Recycle, an Israel-based CDEW recycling company. It added that Shtang Recycle is preparing to build a recycling plant with a production capacity of 0.6Mt/yr of CDEW waste materials. The output from the plant will be used as raw materials for aggregate production.
The focus on CDEW recycling was flagged up at Cemex’s investor event in November 2022. It said that it was targeting a recycling rate of 14Mt/yr of construction and demolition waste by 2030. Other managed waste stream goals included doubling the amount of municipal and industrial waste it manages, to achieve a 50% to fossil fuel substitution rate, and increasing its usage of alternative raw materials and by-products by 30%, thereby eliminating 13Mt/yr of extracted materials.
Cemex is not alone in targeting the CDEW waste sector. Holcim’s recent work in the area goes back to at least 2016 when a recycling unit near its Retznei cement plant in Austria started processing 130,000t/yr of CDEW. It announced in December 2022 that it was setting up a similar recycling centre, also in Austria, at its Mannersdorf cement plant. In October 2022 Holcim acquired Wiltshire Heavy Building Materials in the UK. This company recycles 150,000t/yr of construction and demolition waste into aggregates and concrete. Holcim linked the acquisition to its Strategy 25 target of recycling 10Mt/yr of construction and demolition waste by 2025.
Activity by other cement companies includes the commissioning of a construction waste recycling plant at Gennevilliers in France by CRH-subsidiary Eqiom in April 2022. It was aiming for a target of 50,000t in 2022. In November 2022 Heidelberg Materials agreed to acquire RWG Holding based in Berlin, Germany. Then, in December 2022, it announced a deal to buy Mick George Group in the UK. Both proposed acquisitions are subject to competition authority approval. Heidelberg Materials’ current target is to offer circular alternatives for half of its concrete products by 2030.
The moves by the bigger cement companies into the CDEW sector follow sustainable thinking and the waste hierarchy. Yet the big prize here is to gain a route to dispose of some of their CO2 emissions through recarbonation and this has been flagged up in several net-zero roadmaps for the cement sector such as those by Cembureau and the Global Cement and Concrete Association (GCCA). Holcim has been involved in the FastCarb project in France, running a pilot at its Val d’Azergues cement plant in 2021. Heidelberg Materials has been testing its own process with so-called recycled concrete paste. The development now appears to be that utilising CDEW has entered the sustainability strategies for some of the big cement-concrete-aggregate producers, targets have been set and acquisitions are happening.

Republic Cement and Ecoloop seek new waste management partners
30 January 2023Philippines: CRH subsidiary Republic Cement and its waste management subsidiary Ecoloop are seeking to establish partnerships with 'sustainability-minded' organisations. BusinessWorld News has reported that Republic Cement and Ecoloop process waste for 12 private companies and 30 local government units. Philippines law will require that large organisations recover 80% of their plastic packaging waste by 2030. For 2023, the minimum is 2023.
Ecoloop managing director Angela Edralin-Valencia said “Our goal is to make our cement a greener and more environmentally friendly product. Our ambition is to replace 50% of our fuel consumption with alternative fuel (AF)." She added "A lot of investments have to be put in place from our end to get to that number, but we are still reviewing our options.”
Australian government to reduce industrial emissions limits
20 January 2023Australia: The government plans to reform its CO2 emissions Safeguard Mechanism in line with its stated goal of net zero CO2 emissions by 2050. Under the latest proposals, 215 industrial plants, including Australia's cement plants, will have to reduce their CO2 emissions by 4.9% year-on-year every year until 2030. The Australian newspaper has reported that the government is currently receiving submissions on the proposed reform as part of its consultation process, which will end on 24 February 2023.
The Business Council of Australia and the Australian Industry Group have encouraged the government to introduce an adjustment mechanism for imports, based on the EU's Carbon Border Adjustment Mechanism (CBAM), in conjunction with any tightening of the Safeguard Mechanism.

Vicem's full-year sales grow in 2022
09 January 2023Vietnam: Vicem recorded full-year sales of US$1.68bn during 2022, up by 17% year-on-year. The producer sold 27.5Mt of cement, down by 6.7% year-on-year. Export sales volumes declined more sharply than those on the domestic market. Vicem responded to the cost impacts of economic disruptions arising from the on-going Russian invasion of Ukraine by raising its cement prices. Nonetheless, its profit fell by 30% year-on-year to US$63.9m.
Vietnam News Summary has reported that Vicem is aiming to achieve sales growth of 4% year-on-year in 2023, to US$1.74bn. Export sales growth prospects are strong, since China resumed its import of foreign goods at the end of December 2022. China consumed 54% of all Vietnamese cement exports in 2021.
