Lafarge Cement ends Čížkovice cement plant's natural gas reliance through alternative fuels use
17 August 2022Czech Republic: Lafarge Cement says that it has achieved an alternative fuel (AF) thermal substitution rate of 95% at its Čížkovice cement plant. The plant's fuel mix includes contaminant fractions from local plastic recycling. As a result of the move, the plant no longer uses any natural gas in its cement production.
In 2022 as a whole, the producer plans to increase its share of reduced-CO2 cement sales, increase construction waste recycling in its products and reduce its cement's water consumption.
National Cement Company of Alabama’s Ragland cement plant upgrade to reduce CO2 emissions by 40%
25 July 2022US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO2 emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.
Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."
Fauji Cement eliminates 8030t of CO2 emissions in 2022 financial year through AF subsititution
20 June 2022Pakistan: Fauji Cement says that it eliminated 8030t of CO2 emissions across its three cement plants through alternative fuel (AF) substitution in its 2022 financial year. The figure constituted 3.8% of a total 215,000t of emissions saved in the year by the company’s on-going sustainability initiatives.
Geminor commissions RDF line in Aalborg
06 June 2022Denmark: Norway-based Geminor has commissioned a new refuse-derived fuel (RDF) production plant in Aalborg, Jutland. The plant is equipped with a windshifter separator, allowing it to extract up to 70% of plastic in residual waste, in addition to metals and wood. This produces a heavy bio-RDF with low fossil content, of the type previously developed by the company at its HUB research facility in Landskrona, Sweden. Though more expensive to produce than other types of RDF, the company believes the fraction offers higher profitability due to its taxation benefits.
Argentina: Holcim Argentina achieved 8.4% alternative fuel (AF) substitution in its cement production in its cement production in 2021. That year, it reduced its CO2 emissions per tonne of cementitious material by 4.2% compared to 2017, to 505kg/t from 527kg/t.
Waste management partner Geocycle processed 140,000t of waste in 2021, up by 20% from 2020 levels. This included 4000t of waste tyres, which alone eliminated 2300t of CO₂ emissions. Geocycle inaugurated Argentina’s first municipal solid waste (MSW) classification facility in Córdoba in November 2021.
Mexico: Cemex reported 29% alternative fuel (AF) substitution in its global operations in 2021, according to its Integrated Report for the year. The report stated that the group reduced its CO2 emissions per tonne of cementitious material by 4.7% year-on-year.
Entsorga supplies solid recovered fuels storage, feeding and dosing systems to Indocement Tunggal Prakarsa
11 March 2022Indonesia: Entsorga has dispatched two Spider bridge cranes and two Pelican feeding and dosing systems for the construction of two new solid recovered fuel (SRF) storage, feeding and dosing systems at Indocement Tunggal Prakarsa’s 11.9Mt/yr Citeureup cement plant in Bogor Regency. The systems will have a total capacity of 50t/hr. An advanced supervision system will monitor and control their 24-hour operation. The Italy-based supplier says that both lines are highly automated and will reduce both CO2 emissions and fuel consumption.
CEO Francesco Galanzino “The systems will help the cement plant to maintain its 2030 sustainability commitments, in line with the policies of HeidelbergCement who is a real first mover in the path toward sustainability. Such project it is a very important step in a Country where environmental policies are in their early stage.”
Cemex USA to increase alternative fuel substitution at Brooksville cement plant to 30%
28 February 2022US: Cemex USA plans to increase its rate of alternative fuel (AF) substitution at its 2.2Mt/yr Brooksville, Florida, cement plant to 30%. It will also increase its AF use at its 1Mt/yr Demopolis, Alabama, cement plant. At both plants, the new fuel mix will include biomass. The producer says that it will complete the plants’ transitions before 2023.
US: Lafarge North America has reported that its Paulding, Ohio, plant achieved 99% alternative fuel (AF) substitution in its cement production, up from 95% in past years. The operator said that the fuel change saved 205,000t of CO2 emissions in 2021.
Boral invests in chlorine bypass technology at Berrima cement plant
21 February 2022Australia: Boral plans to install chlorine bypass technology at its Berrima cement plant in New South Wales. The Illawara Mercury newspaper has reported that the installation will help the plant to double its alternative fuel (AF) substitution rate to 100%. This is one of the ways in which the producer aims to reduce its Scope One and Two emissions by 46% between 2020 and 2030.
