From a US$150 million expansion across three Mozambican plants to a U.S. cement tariff rollback, a biochar-from-sewage breakthrough, and banned-plastic shipments to a kiln in Tamil Nadu, the global cement value chain is being reshaped on multiple fronts at once.
African Supply Expansion: Cimentos de Moçambique’s US$150M Programme
Cimentos de Moçambique presented a US$150 million investment programme at the FACIM 2026 trade fair in Maputo, targeting clinker output at three of its four factories [S2]. The largest single project is a US$110 million rebuild of the Nacala integrated plant in Nampula province, inaugurated by President Daniel Chapo on 24 July 2026 [S2]. Nacala’s capacity triples to 1.2 million tonnes per year, anchored by a new 3,000-tonne-per-day kiln [S2].
A separate US$60 million project at the Dondo plant in Sofala province doubles cement capacity to 1.3 million tonnes per year, supported by a 3,000-tpd kiln, an 80-tonne-per-hour vertical mill, and a 120-tonne-per-hour bagging line [S2]. The Matola kiln near Maputo, rated at 2,000 tpd, has been rehabilitated and returned to service [S2]. Combined, the three kilns deliver 8,000 tpd of clinker capacity, with a Mwanza quarry in Gaza province refurbished to secure raw materials [S2]. The company is controlled by China’s Huaxin Cement following its takeover of InterCement’s African business, cleared by Mozambican regulators [S2]. Commercial director Ailton Novele framed the project as a means of reducing reliance on imported clinker and presented it alongside a search for new commercial partners, suppliers, and investors [S2].
Trade Policy Signal: U.S. Drops 50% Tariff on Canadian Cement
The Trump administration has dropped a 50 per cent tariff on Canadian cement, a move reported as evidence that the administration will reconsider duties when U.S. manufacturers demonstrate the levy is hurting them [S3]. The Financial Post article frames the reversal as a template for other industries caught in the trade war, suggesting that organized pressure from affected U.S. businesses can unlock relief [S3]. For cement-equipment buyers evaluating North American project economics, the policy change directly alters landed-cost assumptions and the competitiveness of cross-border capacity [S3]. The decision is presented by observers as a case study in leverage: competing interests that traditionally influence trade policy have, under the current administration, become more aggressive and more visible [S3].
Alternative Binders: Sewage-Sludge Biochar at 10% Replacement
Researchers in India have produced biochar from treated sewage sludge at a Warangal, Telangana treatment plant run as a public-private partnership, ground it into a fine black powder, and substituted it for a tenth of the cement in a concrete mix [S5]. After 91 days, the resulting concrete was 21 percent harder to crush than the reference mix [S5]. The work targets the cement-paste binder, which accounts for most of concrete’s climate footprint — between 5 and 8 percent of global human-caused CO2 emissions, driven primarily by limestone chemistry rather than kiln fuel [S5]. Global concrete production is projected to climb from roughly 14 billion cubic metres a year toward 20 billion by mid-century, sharpening the case for partial cement replacement [S5]. The authors flag the result as promising but preliminary, noting the paper is an early-access version still subject to edits [S5].
Waste-to-Energy: Banned Plastics Routed to a Tamil Nadu Kiln
Thanjavur district officials in Tamil Nadu have transported 3 tonnes of banned plastic products to a cement factory for co-processing, while imposing ₹1 lakh fines on the violating traders [S4]. Cement kilns are increasingly used as a disposal route for non-recyclable plastics because of their high process temperatures and residence times, converting waste into energy while incorporating mineral residues into clinker [S4]. The episode illustrates the operational interface between municipal enforcement and cement-plant intake, and the compliance cost structure now attached to single-use plastic bans in India [S4]. For procurement teams, the signal is that kiln operators are positioned as downstream receivers in state waste-management chains, with implications for feedstock contracts and community relations [S4].
Procurement Read-Across
For equipment buyers, the four signals point in a consistent direction: nameplate capacity is being added where imports are being displaced (Mozambique), tariff-driven cost curves are being redrawn (U.S.–Canada), alternative binders are entering early-stage qualification (India), and kiln intake streams are being formalized for waste materials (Tamil Nadu) [S2][S3][S4][S5]. Cimentos de Moçambique’s combined 8,000 tpd of clinker and US$110 million Nacala rebuild are concrete spec sheets for mills, bagging lines, and kilns; the U.S. tariff reversal is a market-access variable; biochar substitution is a long-horizon R&D input; and the 3-tonne plastic seizure is a marker of how kilns are being woven into municipal compliance [S2][S3][S4][S5]. Buyers should track Huaxin Cement’s supplier calls from FACIM 2026, monitor U.S. Commerce actions on cement derivatives, and qualify SCM supply chains that can accept biochar or waste-plastic residues without compromising clinker chemistry [S2][S3][S5].
