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.”
Russia: Eurocement and the Toshka Centre group of companies have signed an agreement on cooperation in the use of alternative fuels (AF) at Eurocement’s cement plants. The partners signed the agreement within the framework of the Russian Environmental Operator’s nationwide Ecology project. The main area of cooperation between the parties will be the implementation of AF substitution at the cement producer’s gas-burning kiln lines. The Toshka Centre will create an AF production network to supply the producer’s operations.
Innovation and technical development vice president Sergey Demakov said, “The use of AF will allow Eurocement group to reduce natural gas consumption and show savings in fuel purchase costs at the initial stage of the project alone by 10%.”
Lafarge France completes waste processing line upgrade at Port-La-Nouvelle cement plant
09 March 2021France: LafargeHolcim subsidiary Lafarge France has completed a Euro6m modernisation of the two waste processing lines at its Port-La-Nouvelle cement plant. The final phase of modernisation aimed at increasing dosing and injection capacities, optimising unloading, replacing fire detection and protection systems and expanding the control laboratory. The company said that the modernisation will enable it to use 80,000t/yr of refuse-derived fuel (RDF) in cement production at the plant. It says that this will reduce carbon dioxide (CO2) emissions by 30,000t/yr. As a result, the plant’s fossil fuel consumption will decline by 75% in 2021 and by 90% in 2022 compared to 2020 levels. Its long-term aim is to become Europe’s first fossil fuel-free cement plant.
