Golden Bay Cement uses 80,000t of waste in EcoSure reduced-CO2 cement production to date
17 October 2022New Zealand: Fletcher Building subsidiary Golden Bay Cement has co-processed 80,000t of waste in production of its EcoSure reduced-CO2 general-purpose cement at its Golden Bay, Whangarei, cement plant. The plant has achieved a coal substitution rate of 50%. It has processed various waste streams, including 3 million used tyres. EcoSure cement generates CO2 emissions of 699kg/t of product, 20% less than its imported alternatives, according to Golden Bay Cement. Fletcher building CEO Nick Traber said that this figure is 'simply our starting point.' The company's next target is to achieve a 30% CO2 reduction by 2030.
Traber said "We needed to think outside the box, or rather the cement bag to be more precise. The challenge was around what enhancements we could make to our manufacturing processes at our Golden Bay cement works in order to improve the plant's sustainability. We quickly realised that consuming used tyres and wood waste as alternative fuels was a win-win. When we started with the idea in 2015, we were aiming to replace 15% of coal with end-of-life tyres. Fast forward to 2022, and our rate of coal substitution is now at 50%, which has obviously delivered further reductions in carbon emissions, as well as helping to offset increased coal costs."
FLSmidth secures Euro150m sustainability-linked loan
13 October 2022Denmark: Nordic Investment Bank (NIB) has granted a 150m loan to FLSmidth to support technological developments for the growth of sustainability in the cement and mining sectors. The supplier said that the loan tracks three core sustainability indicators: FLSmidth's ratio of partners with SBTi-certified science-based targets, FLSmidth’s own Scope 1 and 2 CO2 emissions and its products' Scope 3 impacts.
Chief financial officer Roland Andersen said “With our MissionZero pledge, we are fully committed to developing technologies and solutions that will enable the mining and cement industries to move towards zero emissions by 2030. As sustainability is an integral part of everything we do, it is only natural for us to also link our financing to our sustainability ambitions. This is a first step in this direction, and we are very pleased with the long-term commitment provided by NIB."
Science-Based Targets Initiative reviews Heidelberg Materials' emissions reduction targets
12 October 2022Germany: Heidelberg Materials has reaffirmed its 2030 CO2 emissions reduction targets and submitted them to the Science-Based Targets Initiative (SBTi) for review. These include a reduction in Scope 1 emissions per tonne of cementitious material of 47% between 1990 and 2030. The initiative will now ensure that the targets conform to a 1.5°C climate change scenario.
Heidelberg Materials chair Dominik von Achten said “We have been actively supporting SBTi’s efforts to develop a 1.5°C roadmap and impactful criteria for the cement industry. With the industry's most ambitious CO2 reduction targets and a steadily growing portfolio of CCUS projects, we are eager to continue leading the way.”
Seratech's carbon-neutral cement wins Obel Award 2022
10 October 2022UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO2 from flue emissions, which can sequester double the CO2 of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.
Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."
Indian Institute of Technology – Madras study quantifies emissions and energy savings of limestone calcined clay cement
03 October 2022India: Research by the Indian Institute of Technology – Madras (IIT Madras) has concluded that limestone calcined clay cement (LC3) production emits 40% less CO2 than ordinary Portland cement (OPC) production, and is 20% less energy intensive. United News of India has reported that the Switzerland-based Swiss Agency for Development and Cooperation supported the study.
Three cement producers among Spanish pollution top 10 in 2021
28 September 2022Spain: Sustainability Observatory's Decarbonisation 2022 report has named FCC, Cemex and Holcim on a list of Spain's top 10 CO2 emitters. Construction conglomerate FCC, parent company of Cementos Portland Valderrivas, was the seventh largest contributor the country's CO2 emissions during the year. Mexico-based Cemex placed joint eighth with energy provider Iberdrola at 2.4Mt-worth of CO2 emissions in 2021, followed by Switzerland-based Holcim with 2Mt.
Spanish CO2 emissions grew by 5.1% year-on-year in 2021, and by 3% across industries subject to emissions credit trading, which include the cement sector. Together, the top 10 emitters accounted for 57% of these industries' emissions, and 19% of total national emissions.
Quebec government orders St Mary’s Cement’s Port-Daniel-Gascons cement plant to reduce dust emissions
20 September 2022Canada: The Quebec Ministry of the Environment has ordered St Mary’s Cement’s integrated plant at Port-Daniel-Gascons to reduce its dust and other emissions to government-mandated levels. The notification follows an incident that occurred over the summer of 2020 and has reoccurred since on occasion. The order requires, amongst other measures, that the subsidiary of Brazil-based Votorantim allow an independent expert recognised by the department to carry out an assessment of air filtration equipment at the plant and propose ways to improve the situation.
Cemex UK purchases 10 reduced-CO2 tipper trucks
01 September 2022UK: Cemex has bought 10 Volvo 460 8x4 tipper trucks for use at its Angerstein Wharf aggregates depot in Greenwich. From there, the trucks will deliver sand and aggregates all around London. The trucks’ bodies are made of lightweight aluminium, and they conform to Euro 6 emissions standards. This corresponds to 80% NOx emissions reduction and 50% particulate emissions reduction compared to Euro 5 standards.
Cemex UK fleet engineering manager Nigel Ponton said “The addition of these new trucks to our fleet will enable us to better meet customer demand, safely and efficiently. Safety is the number one focus whenever we add new trucks to our operation and these Volvos tick every box in that respect.” Ponton continued “These trucks will all be working in busy streets across London so it’s imperative we provide our drivers with the best tools possible to do the job and help protect any vulnerable road users. Moreover, thanks to the improved fuel efficiencies and enhanced payload these new Volvos are the most sustainable vehicles we’ve ever had and will help decarbonise our delivery footprint.”
Nesher fined for Clean Air Law violations
23 August 2022Israel: Nesher Cement has been fined US$1.9m for violations of the Clean Air Law at its cement factory in Ramla. The fine was issued for repeatedly exceeding permitted emissions limits, including for mercury/mercury compounds and particulate matter. 22 violations have been recorded since July 2022.
“The recent fine issued against the Nesher Ramla cement plant is a very welcome step forward, but it’s far from enough,” said Knesset member Alon Tal, chairman of the Subcommittee on Environmental and Climate Impacts on Health. “Just a month ago the ministry issued a permit for seven years to the factory, notwithstanding its dubious record as a serial violator of Israel’s Clean Air Law. This makes absolutely no sense.”
Local activists living near the factory were also not satisfied with the value of the fine. “The Environmental Protection Ministry has confirmed that there’s an unusual rate of cancer, especially lung cancer, in Ramla and Lod,” said Benjamin Ruggill, leader of a citizen action group, to local press.
