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.
Coimbatore Municipal City Corporation supplying 54,800t/yr of RDF to Ariyalur cement plants
03 May 2022India: Coimbatore Municipal City Corporation says that it has reached a rate of 54,800t/yr in refuse derived fuel (RDF) deliveries to cement plants in Tamil Nadu's Ariyalur District. The Indian Express newspaper has reported that the corporation collects 1000t/day of waste, from which its sorts 150t/day of non-biodegradable waste into RDF. It has launched landfill mining at a 26.7ha tip in Vellalore, where it expects to extract several tens of thousands of tonnes more of non-biodegradable waste.
Dangote Cement co-processed 89,000t of waste in 2021
25 April 2022Nigeria: 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.
Speaking on International Mother Earth Day on 22 April 2022, head of AF projects Peter Anagbe said that the company continues to demonstrate its commitment to sustainable waste management through its advancement of local community recycling projects.
Cemex signs industrial waste processing deal with 3M
08 April 2022Panama: Cemex has secured a supply of 30t/yr of industrial waste for use at its Panamanian cement plant from US-based industrial conglomerate 3M. The waste will consist of high-calorific residual foam and wool.
Cemex South, Central America and the Caribbean regional president Jesús González said “We are very pleased to make this alliance that strengthens our company’s path towards our carbon neutrality goal by 2050. Cemex and the building materials industry can play an important role in the creation of a truly circular economy. As evidenced by this agreement, we welcome this challenge and are moving aggressively to create the better circular world of the future.”
India: ACC and Ambuja Cements have together installed a Geocycle Bubble Barrier plastic waste separator in Bhakra Beas Management Board Lake at Sunder Nagar, Himachal Pradesh. The installation will collect the waste for use as refuse-derived fuel at ACC’s Gagal cement plant in the state.
The Holcim India subsidiaries’ first such installation, on the Mantola Canal in Uttar Pradesh, has collected 500t of plastic waste since its commissioning in April 2021, and is targetting a total of 2400t in 2022.
Holcim India CEO and managing director Neeraj Akhoury said "We are committed to building a sustainable future by adopting clean and green technologies. Our efforts and expertise in co-processing has created a unique solution to sustainable disposal of the marine plastic waste that creates pollution. This initiative will also contribute towards promoting circular economy. Taking this mission ahead, we will continue our efforts to implement this innovative technology across the country."
Norway: Geminor processed 67% of waste that it handled in 2021 into refuse-derived fuel (RDF) and solid recovered fuel (SRF). The company said that the figure represents a 3% decline from 2020 levels. It handled a total of 1.73Mt of waste in nine European countries in 2021.
CEO Kjetil Vikingstad said “The Covid year 2021 has been another challenging year for the European waste industry in terms of volumes, logistics, transport and varying market mechanisms. The RDF market, in particular, has differed with lower volumes in circulation due to reduced exports from countries such as the UK and Finland. At the same time, other countries - such as Poland, Denmark, and Italy - have experienced growth, which has helped obtain a balance in the market.”
Sumitomo Osaka Cement’s Ako cement plant to receive future disaster waste from Hyogo Prefecture
18 November 2021Japan: Sumitomo Osaka Cement has secured an agreement with Hyogo Prefecture for the future reception and processing of the prefecture’s waste from disasters such as earthquakes. The company says that the agreement will facilitate the rapid reception of such materials and to best support clean-up efforts.
President Hironori Morohashi said “We will continue to strengthen our cooperative relationship with Hyogo Prefecture and work to form a sustainable society and develop and improve the region.”
Untha signs distribution agreement with Axia
07 October 2021Japan: Austria-based Untha has awarded an exclusive distribution agreement in Japan to Axia. The distributor has taken delivery of a mobile Untha XR shredder for use as a demonstration unit at its customer sites and ordered six more models.
Axia CEO Kazunori Kawata said “China’s ban on waste plastic imports means Japan has sharpened up on its domestic recycling capabilities. The introduction of Untha’s engineering experience will really disrupt the market. Operators are starting to think differently about machine reliability, throughputs and lifecycle costs. As a nation, we must increase our productivity and capacity, and we need a different class of machine to be able to do this – one that is highly configurable, versatile and built to last. Output precision is also crucial.” He added “If Japan is to enhance its commitment to the environment, it is important that we seek to use energy efficient technologies within our waste and recycling facilities. Renowned globally for using 75% less energy than competitors’ diesel-hydraulic machines, the Untha XR shredder doesn’t just improve the net carbon impact of the process – it keeps fuel costs low, too. Some customers have been known to save US$135,000/yr in fuel costs alone.”
Holcim Russia envisions 15% emissions reduction by 2030 and carbon neutral cement production by 2050
05 October 2021Russia: Holcim Russia has committed to realising a 15% CO2 emissions reduction in its cement production between 2019 and 2030 to 475kg/t from 561kg/t. It plans to further reduce its cement’s CO2 emissions to 453kg/t by 2050, and to implement further measures to ensure its net carbon neutrality at that time.
Corporate relations director Vitaly Bogachenko said “The company's goal is to drastically reduce carbon emissions, and there are two working solutions for this. The first is the use of alternative fuels (AF) obtained from different types of waste: residues of municipal solid waste after sorting and extraction of all useful fractions from them, used tyres and others. The presence of biomass in them makes such fuels carbon neutral, so emissions during production are significantly reduced. The second solution is to replace carbon-intensive raw materials. For example, instead of limestone, we use slags. The recipe for the cement is completely different - thanks to the new composition and the lower temperature during the firing process, the carbon footprint in the production of cement is reduced.”
Hachinohe Cement to use cargo and oil from shipwreck as cement fuel
17 September 2021Japan: Sumitomo Osaka Cement subsidiary Hachinohe Cement has announced that it will be receiving heavy oil and woodchips from cargo washed ashore from the wreck of a ship at Hachinohe port on 11 August 2021. The company plans to use the waste as refuse-derived fuel (RDF) for cement production at its cement Hachinohe cement plant. The company said that the oil spill from the incident has had a great impact on the region. It added “In the future, we would like to actively promote the acceptance of wreckage with heavy oil attached and cooperate in the early resolution of the situation.”
