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.

Pakistan: 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.

Russia: 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.

Cyprus: 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.

Nigeria: Dangote Cement says that it co-processed 89,000t of waste as alternative fuel (AF) in its cement production as a group in 2021. The Nigerian Guardian newspaper has reported that the source materials consisted of biomass, waste tyres, fly ash and oil-based waste.

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.

Mexico: Cemex’s Torreón cement in Coahuila has concluded its first 100% alternative fuel (AF) trial run.

Chief process officer Gerardo Castilla said that the move is ‘A small step for Cemex but a big step for the world.’ He added “Let’s go for more.”
