Japan: Mitsubishi UBE Cement’s joint project with the city of Kitakyushu to pilot carbon recycled materials in public infrastructure has been selected for the Ministry of Economy, Trade and Industry’s 2024 grant programme.

Centred around the producer’s Kyushu plant in Kurosaki, Kitakyushu, the project will recycle CO₂ and waste cement from local sources for use in municipal construction. Mitsubishi UBE Cement said it aims to establish a model for resource circulation that can be expanded nationwide.

Portugal: Cimpor will invest €155m in establishing a new research and development centre focused on sustainable construction, CO₂ reduction and digital transformation. The investment will also cover the modernisation of Kiln 7 at the producer’s Alhandra cement plant. The new centre will focus on technologies such as low-clinker cement development, carbon capture and alternative fuels, using recycled concrete and 3D printing. The building itself will incorporate calcined clay-based cement and recycled aggregates.

The new centre will create over 100 jobs and serve as a hub for collaboration with universities and startups, as well as serve as a location for conferences and workshops. The building will operate as a ‘living lab’, with real-time monitoring of its thermal and structural performance and energy consumption.

The chair of Cimpor Global Holdings, Suat Çalbiyik, said “In 2018, we operated only in Portugal and Cape Verde with around 1800 employees. Today, we are the world’s third-largest cement group… with 8000 employees in 14 countries and a production capacity of 112.5Mt/yr of cement.”

UK: LKAB Minerals and Forterra have partnered to produce recycled calcined clay from unwanted bricks as a traditional cement replacement, with production set to begin at LKAB’s Flixborough plant in Scunthorpe in June 2025. The material is made by crushing bricks sourced from Forterra’s Kings Dyke site in Peterborough.

LKAB Minerals UK managing director Steve Handscomb said “The traditional manufacturing and materials industries have to work harder than other less energy intensive industries, and need significant investments to upgrade equipment. We are committed to playing a role in the transition. In fact, we are already a significant producer of GGBS, and in our minerals division, 45% of the minerals we sell are from recycled sources or by-products.”

Lithuania: Recycling company Ekobāze is set to construct a plastic byproducts and solid recovered fuel (SRF) processing complex in the Akmenė Free Economic Zone. The project is valued at about €12m and received €10m in EU financing, according to BNS News. It will create 60 new jobs. The complex will supply SRF to Akmenės Cementas, the sole cement producer in Lithuania, utilising post-consumer plastic unsuitable for recycling in its production processes. Ekobāze will process other plastic into pellets. Construction will begin at the end of 2025, with production starting in early 2027.

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: Heidelberg Materials has invested in EnviCore, a Canada-based startup that is developing low-carbon solutions. Together, the companies will focus on increasing the use of recycled construction and demolition materials as supplementary cementitious materials (SCM). This collaboration includes planning a pilot SCM production facility near one of Heidelberg Materials' recycling hubs, pending an upcoming feasibility study. Heidelberg Materials has also acquired a minority stake in EnviCore.

Katharina Beumelbur, chief sustainability and new technologies officer and member of the managing board of Heidelberg Materials, said “EnviCore’s novel approach has the potential to unlock new possibilities of increasing the amount of recycled materials we use in our products. This could pave the way to further reduce our need for virgin materials, contributing towards preserving valuable natural resources and protecting our environment.”

Spain: Packaging and paper manufacturer Mondi has co-founded Paper Sacks Go Circular Spain, an alliance aimed at enhancing the circularity of used paper bags within the construction sector. The alliance consists of 12 European companies collaborating to eventually elevate recycling processes for construction materials like cement, plaster and insulation. The alliance will start with paper bags, then expanding to other streams such as construction and demolition materials. The initiative aligns with the goal of increasing the recovery rate of construction byproducts in Spain, currently at 48%, according to the latest data from the Spanish National Statistics Institute.

Circular economy manager at Mondi Flexible Packaging, Carlos Martinez Ezquerra, said "This initiative demonstrates Mondi’s commitment to collaborating with industry partners across the value chain to increase recycling rates for used paper bags. It creates a scalable approach for the rest of Europe and other industries, leading to a reduction in ‘waste’ management costs and a significant increase in the valorisation rate, and supports transparency and traceability of the circular economy. We are proud to be one of the founding initiators."

Bangladesh: LafargeHolcim Bangladesh Limited (LHBL) has entered into a memorandum of understanding with conglomerate PRAN-RFL Group. The agreement focuses on the sustainable disposal of non-biodegradable and non-recyclable materials from PRAN-RFL's food products at LafargeHolcim's Chhatak cement plant in Sunamganj.

Corporate finance director Uzma Chowdhury noted its operation of three recycling plants capable of processing 40,000t/yr of discarded materials. He said "Some materials cannot be recycled. These often mix with soil and water, causing significant environmental harm. This is why we are partnering with LafargeHolcim to ensure that non-recyclable materials are managed in an effective and environmentally friendly manner. Now, non-biodegradable and non-recyclable food products produced by Pran-RFL Group will be managed in a sustainable manner at the LafargeHolcim plant."

CEO of LafargeHolcim Bangladesh Mohammad Iqbal Chowdhury said "LafargeHolcim has been working for a zero waste future though its Geocycle wing. Our Chhatak plant is the only integrated cement plant in Bangladesh that produces clinker. This enables us to manage different kinds of ‘waste’ sustainably."

Mexico: Veolia Mexico announced in its sustainability report that it has managed the recycling and reuse of nearly 20,000t of waste for the cement industry, as well as reducing water consumption by 15%. The company has reportedly treated 1.1Mt of solid waste and generated 22,134MWh of electricity from biogas.

Leslie Lamadrid, director of sustainability, said "This demonstrates the effectiveness of the strategies implemented and Veolia's dedication to achieving its sustainability goals."

US: The Continental Cement Davenport plant in Buffalo, Iowa, has celebrated the expansion of its facility, which now enables the reuse of post-consumer materials. This initiative will substitute approximately 50,000t/yr of fossil fuels with discarded materials that would otherwise be incinerated or sent to landfill.
