Mexico: Regenera, a subsidiary of Cemex, has launched a pilot project at its Broquers Ambiental plant in Querétaro to transform the city’s organic waste into alternative fuel using a drying process known as ‘biosecado’. This initiative makes Querétaro the first zero waste municipality in Mexico, according to the company. The plant now processes almost 90% of the municipality’s waste, transforming over 8000t monthly into biomass to reduce the amount of material sent to landfill.
Vice president of urban solutions at Cemex Mexico, Antonio Balmori, said "This project that we started today at our Broquers Ambiental plant excites me very much because it will take the city of Querétaro to the next level in waste management, where we will seek to take advantage of 100% of the urban solid waste generated in the municipality."
Azerbaijan: Norm Sement Company will utilise sludge from drilling wells for powering its cement plant, following an agreement with the State Oil Company of Azerbaijan (SOCAR), according to Trend. The plant has a capacity exceeding 2.1Mt/yr of cement and 5300t/day of clinker.
A source said "In collaboration with SOCAR, we tried sludge to power Norm Sement last year. Negotiations on a long-term deal are underway. Cooperation to use industrial waste supports the country's green economy strategy.”
US: Holcim’s Hagerstown plant in Maryland has increased its alternative fuels substitution rate to 45%, equivalent to 58,000t/yr of engineered fuel. This US$11m initiative utilises end-of-life materials like non-recyclable paper, plastics and fibres, sourced from commercial and industrial materials like packaging. Geocycle, a subsidiary of Holcim US, will process these materials at its new Cumberland facility, which has a capacity of up to 75,000t/yr.
Senior vice president of Manufacturing North for Holcim US, Michael Nixon, said "Expanding our alternative thermal energy use to 45% provides multiple environmental and economic benefits, from lowering the net carbon intensity of our cement to reducing our consumption of traditional fuels. Importantly, it enables us to play a role in the circular economy, offering a highly safe and ecological solution for unused materials."
Saraburi cement plants to turn waste into energy
08 April 2024Thailand: Saraburi, which houses Thailand’s key cement plants, is expected to start converting waste to energy in a project led by the Thai Cement Manufacturers Association (TCMA). TCMA has developed a pilot project to create ‘ignitable waste pallets’, which will replace imported coal in cement production, according to TCMA chair Dr Chana Poomee. The process involves using waste from mining, cement plants and local communities to produce fuel, focusing on waste that cannot be reused or recycled.
Seven cement plants are located in the Tan Diao subdistrict due to its proximity to limestone mountains essential for cement production. The province is facing a growing waste management problem, owing to urbanisation and the expansion of agribusiness in the area. ‘Saraburi Sandbox’ project, a public-private-people partnership (PPP), seeks to address these issues.
Kittipong Promwong, president of the National Higher Education, Science, Research and Innovation Office, believes the Saraburi Sandbox is crucial to the government's commitment to lowering CO₂ emissions.
Forty cement and concrete companies commit to the Global Cement and Concrete Association’s Roadmap to Net Zero
12 October 2021World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).
Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO2 emissions by 2030 and the elimination of 4.9Bnt of CO2 emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.
GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”
Saudi City Cement Co to invest US$6.7m in alternative energy project
04 December 2014Saudi Arabia: Saudi cement producer City Cement Company has announced that it intends to invest US$6.7m in an alternative energy project. The Chinese engineering company Sinoma will carry out the project, anticipated to be completed by 30 June 2015. Without providing further details on the nature of the project, City Cement said that it will use its own funds and/or Murabaha financing to fund it.
