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.

Canada: Ash Grove Mississauga cement plant has entered a proposal with the Ministry of Environment Conservation and Parks to burn alternative fuels. This includes materials such as construction and demolition materials, paper fibre, wood, plastic and industrial rubber, according to the Insauga newspaper. Local residents have expressed concerns about potential toxicity and environmental impacts due to emissions from the plant entering the atmosphere. The association reportedly objected to a previous application allowing higher emissions levels at the plant. Ash Grove will address these concerns in a public meeting scheduled for 12 September 2024.

Mexico: A second industrial byproducts processing line has been inaugurated at the Cemento Cruz Azul plant in Tepezalá, Aguascalientes. The new facility, which cost US$8.5m, will create 100 jobs and convert over 66,000t/yr of post-consumer materials into energy for the cement plant's processes.

Víctor Manuel Velázquez Rangel, president of the board of directors of Cooperativa Cruz Azul, said "This is the result of joint work, teamwork and a shared vision with the State Government, which has always been concerned about the carbon footprint, sustainability and the environment. With this project we leave testimony of our great commitment and demonstrate that innovation and technology can go hand in hand with the preservation of the environment."

Germany: The University of Trier is transforming post-consumer materials into ‘ecological’ cement through a new research project that aims to find sustainable alternatives for the construction industry. The project involves using low-CO₂ industrial post-consumer materials as alternative cement binders, such as sludge from gravel and sand mining, as well as dust from quartzite extraction. The research will run for two years and is supported by the German Federal Environment Foundation.

Azerbaijan: Norm Sement Company will utilise sludge from drilling wells for powering its cement plant, following an agreement with the State Oil Company of Azerbaijan (SOCAR), according to Trend. The plant has a capacity exceeding 2.1Mt/yr of cement and 5300t/day of clinker.

A source said "In collaboration with SOCAR, we tried sludge to power Norm Sement last year. Negotiations on a long-term deal are underway. Cooperation to use industrial waste supports the country's green economy strategy.”

Vietnam: Cement producers received 811,000t of boiler slag and fly ash from the Vinh Tan 1 coal-fired power plant in Binh Thuan during the first nine months of 2023. This corresponds to 74% of the volume of the by-products generated at the plant during the period. Việt Nam News has reported that the nearby Vinh Tan 4 coal-fired power plant also ‘almost entirely’ avoided waste in the same way. The Vinh Tan 1 coal-fired power plant ended the period with 4.3Mt of ash and slag in stockpiles, while the neighbouring Vinh Tan 2 Thermal Power Plant had 7Mt.

The provincial government of Binh Thuan Province has lobbied the Ministry of Construction to review and adjust current requirements around HDPE liner use, water quality testing and radiation safety in order to facilitate the use of boiler slag and fly ash in cement and other construction products.

Spain: Cementos Molins has processed 75,000t of waste into alternative raw materials for use in its cement production since opening its Barcelona alternative raw materials plant in September 2022. The plant has a production capacity of 200,000t/yr. It produces the materials from construction and demolition waste and various industrial by-products.

Cementos Molins’ director of corporate development and sustainability, Carlos Martínez, said “Our commitment to the environment is intrinsically linked to our business model, which is based on the development of sustainable and innovative materials.” He continued “We provide a second life to industrial and construction waste that would otherwise end up in landfills, generating high-quality sustainable products from them. The plant has enabled all our cements to incorporate alternative raw materials in their production process. Furthermore, we are working to reduce the carbon footprint of all our concretes, ensuring that, in the short term, all of them include recycled aggregates in their manufacture."

UK: Material Evolution raised US$19m in a Series A funding round to scale production of its 85% reduced-CO₂ cement. Material Evolution produces cement at ambient temperature using its own ambient fusion process. Its inputs consist of industrial wastes and feedstocks. Tech Crunch News has reported that venture capital firm Kompas VC led the funding, with participation from fellow venture capital firms Norrsken VC and Circle Rock Capital, as well as quarried materials producer SigmaRoc.

Material Evolution's CEO Elizabeth Gilligan said “Fusion technology has been hailed as the way to meet humanity’s energy needs for millions of years, whilst emitting no CO₂ or other greenhouse gases."

Philippines: Metal and ores producer Global Ferronickel Holdings (FNI) plans to invest in clinker production operations. The company has indicated that it will also begin producing limestone to supply any clinker plants that it builds. The Manila Bulletin newspaper has reported that FNI's plans also include new ventures into value-added processing, including through the establishment of a ferronickel processing plant and nickel matte processing facility.

Indonesia: Indocement Tunggal Prakarsa has engaged Japan-based environmental consultancy Amita Holdings to support a two-year feasibility study to investigate ways to make its cement production carbon neutral. The study will commence with trials of industrial wastes as alternative raw materials and municipal solid waste as refuse-derived fuel. Amita Holdings says that it is in the process of building a recycling-based society in Indonesia, in partnership with Indocement Tunggal Prakarsa.

Amita Holdings supported the establishment of the community-led Meguru waste sorting facility in Central Java. Two of Indocement Tunggal Prakarsa’s cement plants – the 18Mt/yr Citeureup cement plant and 4.1Mt/yr Paliman cement plant – are situated in neighbouring West Java.
