Aggregate Industries’ Cauldon cement plant starts solid alternative fuels upgrade project
10 June 2021UK: Switzerland-based LafargeHolcim subsidiary Aggregate Industries has launched a Euro15.1m project to increase its use of alternative fuels at its Cauldon cement plant in Staffordshire. The company plans to install a 100,000t/yr pre-processing unit and a new chlorine bypass at the site. The new pre-processing unit, including a haulage and feeding platform, will be built across the road from the main plant and connected via an enclosed conveyor. The company intends to complete the work in early 2022. It says that it will result in a 30,000t/yr CO2 emission reduction.
Chief executive officer Dragan Maksimovic said, “It is great to see us continuing to recognise the importance of sustainability and investing in Cauldon cement plant to ensure that we further reduce carbon emissions and remain sustainable for the long term, both as a local employer and contributor to the local economy, as well as a UK-wide supplier of high quality products and services.”
Portugal: Cimpor Cement plans to upgrade the kiln line of its Souselas cement plant in order to enable 60% refuse-derived fuel (RDF) substitution in its fuel mix. The producer has contracted Denmark-based FLSmidth to install chlorine bypass technology in order to prevent chlorine build-up in the plant’s flue gas. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022.
Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO2 emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”
Germany: Märker Zement has ordered a single-source alternative fuels (AF) storage and conveying system for its Harburg, Bavaria cement plant from Germany-based Beumer. The supplier says that the line will consist of a 700m pipe conveyor, silos, distribution equipment and a screen. It will be equipped with a BG OptiFeed screw weigh feeder. It will connect the preheater both to an existing warehouse and a new one at the site. The line will handle two different qualities of refuse-derived fuel (RDF) and shredded tyres. It will be operated at a maximum capacity of 40t/hr. Commissioning is scheduled for 2022.
Canada: St Mary’s Cement plans to increase its use of alternative fuels to 400t/day from 96t/day at its Bowmanville plant. The Toronto Star newspaper has reported that the plans will entail a 90,000t/yr reduction in the plant’s coal and petcoke consumption.
US: The Department of Environmental Conservation (DEC) of New York state has turned down Lafarge Cement’s application for a licence to burn tyres as an alternative fuel (AF) at its Ravena cement plant. The Times Union newspaper has reported the DEC found that the plant in Albany county was inadequately equipped to burn tyres under the permit for which the company had applied.
Spokesperson Jocelyn Gerst said “We received the DEC’s correspondence and are reviewing it. We will be weighing all available options.”
South Korea: Finland-based BMH Technology has secured a contract to supply three waste shredding lines at Ssangyong C&E’s integrated cement plants at Donghae and Yeongwol. The lines will supply solid recovered fuel (SRF) for the units. Each line will include a Tyrannosaurus type FineScreen and Air Classifier for separating impurities. The full delivery will contain five Tyrannosaurus type FineShredders. The lines will be commissioned in the autumn of 2021.
Donghae plant will become one of the world’s largest SRF shredding plants producing alternative fuels for the cement industry once the order is complete. The unit will produce 80t/hr of SRF with a particle size under 25mm using two lines and four shredders. The cement plant is the world’s largest with a production capacity of 11.5Mt/yr.
Iraq: Germany-based Eggersmann Group has commissioned a 1040t/day refuse-derived fuel (RDF) plant in Sulaymaniyah municipality. The unit uses the company’s biological drying process to increase the yield of RDF from the municipal solid waste (MSW) it receives. Waste & Recycling Middle East and Africa previously reported that the plant can achieve a landfill diversion rate of 80%. A local cement producer will operate the facility and receive MSW from the region for a fee.
New Zealand: Golden Bay Cement has commissioned a waste tyre feeding line at its Golden Bay integrated cement plant in Northland. The producer will cut CO2 emissions by 13,000t/yr by substituting tyres for coal. It will eliminate the 5000t/yr of iron sands used in production and reduce coal use by 15%. The New Zealand government’s Waste Minimisation Fund supplied US$11.2m towards the US$17.5m project.
Government environment minister David Parker told Live News, "This innovative project is a win-win-win for the environment. It reduces a significant waste problem, reuses a valuable resource, and reduces carbon emissions by about 13,000t/yr.” He added that the line, "will divert from landfill or stockpiles about 42% of the estimated 3m waste tyres in Auckland each year. New Zealand needs to address its longstanding problem with waste so we can become the low-waste, low-emissions economy we need to be. "
A TEC wins alternative fuels flash dryer contract at Lafarge Hungary’s Királyegyháza cement plant
30 March 2021Hungary: Lafarge Hungary, part of LafargeHolcim, has awarded a contract to Germany-based Loesche subsidiary A TEC for the supply of an alternative fuel (AF) flash dryer for the 1.0Mt/yr kiln line at its Királyegyháza cement plant in Baranya county. The supplier says that the dryer will use residual hot gas from the chlorine bypass system in conjunction with a satellite burner for firing the material in the kiln. The project also includes the installation of a new AF receiving, handling, and dosing system for a second AF flow firing directly into the kiln burner. A TEC says that it will commission the project in the second quarter of 2021 after the end of the plant’s 2020/2021 winter shutdown.
UK: Cemex has announced a Euro21m investment in an upgrade to its Rugby cement plant. The planned upgrade incorporates green hydrogen into the plant’s cement production process. The company says that the upgrade will enable it to shift to 100% alternative fuel (AF) substitution from fossil fuel use. It said the move is a step towards carbon neutrality in line with its Future in Action programme. The upgrade is expected to be fully operational in June 2021.
Europe, Middle East, Africa and Asia regional president Sergio Menendez said, “We believe that this very significant investment in this upgraded facility supports Cemex’s position to minimise the use of fossil fuels for both environmental and economic reasons. It will enable the Rugby plant to consistently operate with up to 100% AF, which will contribute to our climate action targets.”
