China: Anhui Panjing Cement has ordered an upgrade to its production line from KHD and AVIC. The project includes: installing new triple cyclones in conjunction with existing preheater top stage twin cyclones; a partial modification of downcomer duct; installing a new preheater fan; adding optimised and larger dip tubes for the existing cyclones; installing a new Pyrobox type calciner firing system; adding new raw meal pipes for the two lowest cyclone stages; making calciner modification within the existing preheater building; and installing a new kiln drive system. Where possible the project plans to use reuse existing equipment. It is scheduled for completion by January 2022. It follows a previous upgrade at the plant in 2020 – 2021.

Other recent orders that KHD has announced with China-based cement companies include an upgrade to a production line at Hongshi Group’s Lanzhou plant in Gansu province and the installation of NOx-reducing modifications on a 5000t/day clinker production line operated by China United Cement Baoding.

Brazil: Votorantim Energia and Canada-based CPP Investments have announced the consolidation of their Brazilian energy assets in a new jointly owned renewable energy platform called VTRM. The new company's assets will reach 3.3GW in capacity by October 2022, consisting of 2.3GW in hydroelectric power and 1.0GW in wind power. Its planned projects, including hydroelectric, solar and hybrid power plants, will increase its capacity by 58% to 5.2GW.Its existing assets sold 2.6GW of electricity in 2020. The partners said that the new company will also be well-positioned for future growth, including the acquisition of operational assets and those in planning or under construction. CPP Investment will inject and additional US$269m into the venture following the conclusion of the deal.

As part of the restructuring, Votorantim Energia will cease to manage Votorantim's cement subsidiary Votorantim Cimentos' dedicated energy assets. The cement producer will then incorporate these into its own operations. This will enable Votorantim Energia to focus on energy generation for sale.

Group president João Schmidt said that the consolidation reflects the major role that energy business will play in the company's future. He said "Globally, there is a growing urgency around renewable energy and the energy transition. Alongside a partner like CPP Investments, which has shared our long-term views on energy since 2017, we are ready to accelerate our role in the sector." He added "Through the assets consolidation into a single platform, Votorantim and CPP Investments will share in a new cycle of growth and value generation together."

Germany: Holcim Deutschland has signed a memorandum of understanding with Cool Planet Technologies (CPT) to build a pilot CO₂ capture unit at Holcim’s Höver cement works, near Hannover, based on Hereon’s PolyActive membrane technology. The objective of the unit is to demonstrate the performance, economics and operability of the capture technology at scale. Following this the partners will seek to establish a framework for the technology’s implementation in Holcim’s other cement plants in Germany.

Initial tests are scheduled to commence in the first quarter of 2022 with the first phase of the project, capturing 5600t/yr of CO₂, scheduled for start-up in the second quarter of 2023. If successful, it is planned to expand the unit in two further phases capturing 170,000t/yr and 1.3Mt/yr starting-up in 2024 and 2026 respectively. The final phase will capture over 90% of the carbon dioxide emissions from the Höver plant and deliver the CO₂ in high-purity liquid form for use or sequestration.

CPT is working with Hereon, part of the Helmholtz Association of Research Centres, Germany’s largest research organisation, to commercialise their PolyActive membrane technology after a decade of development. This technology is designed to capture CO₂ from carbon rich gas streams and has already been technically proven in the laboratory and piloted in two coal-fired power stations.

France: Vicat says it aims to start cultivating spirulina at its Montalieu-Vercieu cement plant in the summer of 2022 as part of its Cimentalgue project. It plans to grow 1t/yr until 2024 as part of a trial looking at volume and quality, according to the Agence France Presse. It will use CO₂ and waste heat from the plant to grow the cyanobacteria that can be used as a food source.

The project is being conducted with Algosource and the GEPEA (Process Engineering for Environment and Food) laboratory at the University of Nantes. TotalEnergies is also involved as a financial backer. The project has a budget of Euro2m and is also supported by the Environment and Energy Management Agency (ADEME).

France: Ireland-based Ecocem has opened its new innovation centre, the Centre of Excellence, in Paris. The purpose of the facility is to help to accelerate the development of new technology for the decarbonisation of the cement and construction industries. Ecocem's innovation team will use it for industrial-scale trials in collaboration with industry and academic partners, including Paris-Saclay University and The University of Toulouse. It says that it hopes that one outcome will be the further developmentof the Ecocem reduced-CO₂ product range. Breakthrough Energy Ventures provided funding towards the centre's construction.

Ecocem innovation director Laurent Frouin said “Ecocem is committed to the deep and rapid decarbonisation of the global cement industry. It is essential for the planet and future generations, and it can be achieved through innovation and technology." He added “The cement and construction industries are developing and deploying a range of emission reduction technologies – Ecocem and our new Centre of Excellence will add a further dimension to these efforts.”
