Denmark: Engineering company FLSmidth is working with insulation manufacturer Rockwool and the Technical University of Denmark (DTU) on a research project to develop sustainable process technologies that will increase the use of renewable fuels and raw materials and reduce CO₂ emissions. The project has received a Euro2.7m grant from Innovation Fund Denmark.

The project plans to investigate and optimise high-temperature processes throughout the entire production chain in both companies. The DTU holds experience in this field from the CHEC research centre at DTU Chemical Engineering, which has focused on combustion research and emission abatement in recent years. FLSmidth plans to explore using alternative cement formulas and production methods to enable the company to launch more efficient technologies for using renewable fuels and reducing emissions. Rockwool intends to lower CO₂ emissions and reduce its fuel consumption to make its production become more sustainable.

Sri Lanka: Tokyo Cement has opened an upgrade to its research centre in Colombo. The centre will test and certify cement, concrete and dry mortar products, according to the Daily News newspaper. It is also intended to be an innovation hub for the cement producer to develop new products. Facilities at the site include a wet concrete lab and mini plants to test different blends of cement.

Italy: Wamgroup has inaugurated its new technology centre in Cavezzo. The centre will be used for research, training and as a showroom, according to local media. The enginering company specialises in screw conveyors as well we manufacturing equipment for bulk solids handling and processing, dust filtration, waste water treatment and renewable energy generation. It celebrates its 50th year of business in 2018 following its founding in late 1968.

Norway: The government has proposed continuing funding for Norcem’s CO₂ capture and storage project at its Brevik cement plant. The announcement follows an assessment by the Ministry of Petroleum and Energy of local carbon capture, transport and storage (CCS) projects. The government has proposed to fund FEED studies (Front End Engineering and Design studies) with around Euro8m in 2018. The total funding for the demonstration project in 2018 amounts to Euro29m, including funds transferred from 2017. The proposed funds for 2018 will cover FEED studies of CO₂ transport, storage and up to two capture facilities.

“Of the three CO₂ capture projects evaluated, Norcem has the best conditions for a successful implementation. Norcem has demonstrated project execution abilities and relatively low cost per tonne CO₂ captured compared to the other two capture projects. The cement industry is also a significant contributor to global greenhouse gas emissions,” said the government in a statement Norcem, HeidelbergCement local subsidiary, which sbeat other projects by Yara and Fortum Oslo Varme to the funding.

US: CarbonCure has demonstrated an integrated CO₂ capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO₂ for subsequent utilisation downstream in concrete production and construction.

CO₂ emissions from the Roberta cement plant were captured by SES’ Cryogenic CO₂ Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO₂ utilisation technology. The concrete manufactured with the waste CO₂ from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.

US: The Portland Cement Association (PCA) has supported an infrastructure study by the American Council for Capital Formation (ACCF). It liked how the study highlighted the importance of life cycle cost analysis and competition in paving. “If federal and state decision makers took this report as a playbook, America would see tremendous taxpayer cost savings and stronger infrastructure built to last long into the future,” said PCA President and chief executive officer (CEO) Michael Ireland.

Austria/Germany/Italy: The European Cement Research Academy (ECRA) has launched its oxyfuel carbon capture pilot projects at HeidelbergCement’s Colleferro plant in Italy and LafargeHolcim’s Retznei plant in Austria. The two locations were chosen form a shortlist of five sites. The pilots will test oxyfuel technology on an industrial scale. The test phase of the research is expected to cost Euro80m and the cement industry has contributed Euro25m towards this. ‘Substantial’ funding from European or national research schemes is being sought.

“The technical feasibility of oxyfuel technology can only be proven in real-scale application, but we have sufficient information from our research to believe that we will obtain a positive result after the trials” said Daniel Gauthier, chairman of ECRA.

Canada: Lafarge Canada, University of Calgary, Queen’s University, and Pembina Institute have started a study on the environmental benefits of introducing lower carbon fuels at the Exshaw Cement Plant in Alberta. Eight lower carbon fuels will be researched, including construction renovation and demolition waste, non-recyclable plastic, carpets and textiles, shingles, treated wood products, wood products, rubber and tyre-derived fuels. These sources of fuel have been successfully used at other LafargeHolcim cement plants in Canada.

“Lab simulations, environmental studies, economics and logistics reviews are already underway. All research will be finalised by December 2019 with regular updates provided to the neighbouring communities via a Public Advisory Committee,” said Jim Bachmann, the plant manager of Exshaw .

Additional research by the partners will measure the environmental components associated with the sourcing, processing and full-scale commercial operation of each lower carbon fuel compared to fossil fuels. The project will also measure the benefits of diverting materials from landfills and determine optimal points in the cement manufacturing process to inject each fuel.

In addition to Lafarge’s support, research funding is being provided by Alberta Innovates, Ontario Centres of Excellence, Emissions Reduction Alberta and the Natural Sciences and Engineering Research Council of Canada. It includes research by Millennium EMS Solutions Ltd., Geocycle, and WSP Global Inc.

As part of its 2030 Sustainability Plan, LafargeHolcim aims to replace 30 - 50% of fossil fuel use at its Canadian cement plants with lower carbon fuels by 2020.

Nigeria: Danladi Matawal, the Director-General, Nigerian Building and Road Research Institute (NIBRRI) said the institute’s pilot pozzolana cement plant at Ota in Ogun is ready for commercialisation. He has asked cement producers and other stakeholders to invest in the project, according to an interview with the News Agency of Nigeria reported upon by the Nigerian Sun newspaper.

The pilot project has a production capacity of 2t/day and it is ready for testing on an industrial scale. The unit was commissioned in May 2017 by Ogbonnaya Onu, the Minister of Science and Technology. NIBRRI is also planning a volcanic-based Pozzolana pilot plant in Bokos, Plateau that will be commissioned in 2018.

UK/Europe: Cemex’s South Ferriby cement plant is participating in the European Union (EU) supported enhanced energy and resource efficiency and performance in process industry operations via onsite and cross-sectorial symbiosis (EPOS) project. Designed to enable cross-sector industrial working, the project highlights case studies exemplifying ways for companies to use wastes from other industries to deliver greater efficiency, save raw materials, and contribute to more sustainable processes.

The South Ferriby plant has worked with other companies, including the INEOS chemical company, to determine how waste from INEOS’s production could be used as part of the cement manufacturing process. In addition Cemex Poland and Cemex Research Group in Switzerland will also represent Cemex in the project.

“It is a privilege for Cemex’s cement plant in South Ferriby to participate in this project, collaborating with other companies and partners across Europe. This helps to ensure that we operate our cement plant as efficiently as possible, while learning lessons that we can apply to our other facilities,” said Kevin Groombridge, South Ferriby Cement Plant Environment Manager.
