Canada: Sustainable materials startup EnviCore has raised US$3m in its seed funding round led by CSN Inova Ventures (the corporate venture capital arm of Brazil’s Companhia Siderúrgica Nacional), Heidelberg Materials and others. The funding will scale up Envicore’s production of low-carbon supplementary cementitious materials (SCMs), like mining tailings, slag, shale and glass. The company’s technology reportedly reduces the carbon footprint of cement production by up to 30%, using recycled mineral feedstock, with the SCMs replacing up to 35% of Portland cement in concrete. Proceeds will expand EnviCore's production capacity and support new business development, operations and research and development efforts. Heidelberg Materials, together with EnviCore, will conduct a feasibility study for a pilot SCM production facility close to one of Heidelberg Materials’ recycling hubs.

CEO and co-founder Shahrukh Shamim said "This investment marks a pivotal moment in our journey to commercialise a game-changing technology in the cement industry. The support from CSN, Heidelberg Materials and other investors will allow us to scale up quickly and meet the growing demand for greener building solutions."

India: Cement demand in India is projected to increase by 7 - 8% to approximately 475Mt in the 2025 financial year, down from a compound annual growth rate of about 11% between financial year (FY) 2022 and FY 2024, according to a report by CRISIL Ratings. The company analysed 18 cement producers, which account for over 85% of domestic sales volume. The forecast follows a 3% growth in demand during the first half of FY 2024, affected by an extended heatwave and a labour shortage during the general elections, the Financial Express has reported.

Director of research at CRISIL Market Intelligence and Analytics, Sehul Bhatt, said "Cement demand is expected to rebound in the second half of the 2024 financial year, as construction activity gathers pace across infrastructure and housing segments post-monsoon. Healthy monsoon, improved labour availability after the festive season, and an increase in government spending on infrastructure and housing should drive demand up 9 – 11% in the second half of the year, taking the annual growth tally to 7 – 8%."

Philippines: Holcim Philippines and Universal Robina Corporation (URC) have entered a tripartite agreement with the local government of Obando, Bulacan, to provide incentives for workers at the town's material recovery facility, based on the volume of refuse diverted. The material recovery facility in Obando has collected and sorted 785t of plastic waste for co-processing. Since 2021, URC and Holcim's waste management unit Geocycle has been processing plastic from URC's operations for co-processing. The plastics are converted into alternative fuels used to power the kiln at Holcim’s plant in Misamis Oriental.

Irwin Lee, URC president and CEO, said "This new agreement, with Obando as a key partner, aims to further drive community-based ‘waste’ diversion efforts. We hope to replicate it in other towns and cities to amplify the impact of what we set out to do three years ago."

US: Researchers at UCLA's Institute for Carbon Management have developed a new method called ZeroCAL that could eliminate ‘nearly all’ of the carbon dioxide emissions from the process of cement production, according to the UCLA Newsroom. The team created a process using limestone and a water-based solution containing ethylenediaminetetraacetic acid. Through membrane nanofiltration and an electrochemical process, they produced calcium hydroxide.

To meet ZeroCAL’s water demand, the team suggests focusing on cement plants near coasts or rivers. The researchers are reportedly working with Ultratech Cement to build a demonstration plant that will produce ‘several’ tonnes of lime per day using the ZeroCAL process. Currently, the process requires more energy than traditional lime production methods, but ongoing research aims to reduce its energy consumption.

Gaurav Sant, director of the Institute and professor at UCLA Samueli School of Engineering, said “The ZeroCAL approach offers an elegant solution to eliminate carbon dioxide emissions associated with the process of cement production. First, it addresses the carbon emissions resulting from limestone’s decomposition while providing clean hydrogen and oxygen to heat the cement kiln. Second, it enables onsite decarbonisation while making use of existing kilns and limestone feedstocks without having to build separate carbon capture and storage facilities.”

Bolivia: Bolivia recorded a 2.7% year-on-year increase in cement production and sales in August 2024. According to the National Statistics Institute, production reached 2.6Mt from January - August 2024, up from 2.53Mt in the same period in 2023. Santa Cruz produced 699,062t of cement, followed by La Paz with 679,317t, Chuquisaca with 510,841t, Cochabamba with 384,329t, Oruro with 214,660t and Tarija with 150,068t.

Marcelo Morales, general manager of Itacamba Cemento, noted a year-on-year increase of 3% in domestic demand, with 2.6Mt of cement consumed as of August 2024, saying that the growth was positive ‘considering the current economic situation’.

General manager of the Bolivian Institute of Cement and Concrete, Marcelo Alfaro, also mentioned that Santa Cruz, La Paz and Cochabamba collectively account for about 70% of cement sales in Bolivia, according to La Razón newspaper. The cement industry's installed capacity reportedly stands at 10Mt/yr and the country is facing challenges exporting cement, as neighbouring countries already produce their own.
