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."
UCLA team develops ZeroCAL to cut cement CO₂ emissions 15 October 2024
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.”
Statistics on cement production in Bolivia revealed 15 October 2024
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.
Indonesia: Indocement Tunggal Prakarsa has acquired a 20% stake in Amita Prakarsa Hijau, a company that specialises in the recycling of industrial and municipal refuse and biomass-derived materials into alternative fuel for the cement industry. The deal is valued at US$120,000 and was completed on 8 October 2024.
Switzerland: After an initial increase earlier in 2024, the Swiss cement industry experienced a decline from July - September 2024 with deliveries falling by 8% year-on-year to 914,625t, according to AWP Swiss News. In its latest report, Cemsuisse attributes this decline to a continued reluctance to invest in construction. Despite this, the organisation notes potential signs of recovery, particularly in infrastructure projects.
