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."
Argentina: Holcim Argentina says that it will invest US$40m in capital expenditure in 2022. It plans to invest US$15m in its cement and concrete operations and US$15m in its subsidiary Geocycle's three waste management plants, which supply alternative fuel (AF) for its cement production. Of the remainder, US$5m will go towards the construction of a new dry mortars plant in Córdoba, which the company plans to inaugurate in December 2022.
In 2021, Geocycle processed 140,000t of waste into AF and raw materials for cement production.
Germany: Zement- und Kalkwerke Otterbein plans to invest Euro10m in upgrades to its Otterbein cement plant to increase the sustainability of cement production there. The new equipment will include a hot gas filter SCR catalytic converter system. The producer says that this will install the facility as one of the lowest-CO2 cement plants in the world. Local press has reported that, after commissioning the new system, the company plans to increase its approved substitution of biomass as fuel to 100% from 60%.
South Korea: Sampyo Cement, the Korea Cement Association, LG Chem, Hyundai Rotem and the Korea Engineers Alliance have partnered to tackle the issue of chlorine dust from alternative fuels (AFs). AJU News has reported that LG Chem will develop a product to prevent chlorine dust from attaching to the insides of cement kilns. It will thereby also develop a domestic source of potassium chloride, for use in the production of potassium hydroxide and potassium carbonate. Hyundai Rotem will supply chlorine dust treatment facilities for the project.
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.

Peterburgcement to increase Slantsy cement plant’s efficiency through alternative fuels upgrade
17 June 2022Russia: Eurocement says that its subsidiary Peterburgcement’s Slantsy cement plant in Leningrad Oblast is undergoing an upgrade in order to co-process 100,000t/yr of alternative fuel (AF) in its cement production. The group claims that the upgrade will improve the efficiency of the 1.9Mt/yr plant and reduce its consumption of natural gas by 25%. The purported cost of the upgrade is US$1.77m.
Eurocement previously implemented the same technology at another of its cement plants in the Republic of Mordovia.
Tyre fire breaks out at Vassiliko Cement plant
14 June 2022Cyprus: Vassiliko Cement’s Vassiliko cement plant was the site of a tyre fire in an alternative fuel (AF) storage area on 11 June 2022.

Local residents protested the incident at the site of the plant’s former quarry on 13 June 2022.
Sweden: Cementa plans to increase the share of bio-based alternative fuel (AF) in its Slite, Gotland, cement plant’s fuel mix. The move forms part of the plant’s plan to achieve climate positive cement production from 2030.
Parent company HeidelbergCement’s Northern Europe general manager Giv Brantenberg said “As we capture and store CO2 from the cement production, including emissions from bioenergy, we will be able to manufacture carbon-free cement for the Swedish construction industry.”
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.
