India: Chettinad Cement’s Karikkali plant in Tamil Nadu has been issued a show cause notice by the Central Pollution Control Board (CPCB) for exceeding particulate matter emissions by more than three times the limit. An inspection following Online Continuous Emission Monitoring Systems (OCEMS) data found emissions of 91.2mg/Nm3, according to the New Indian Express. The limit is 30mg/Nm3. The CPCB also found discrepancies with the OCEMS data due to poor instrument calibration.
Ireland: Local environmental activists have accused the Irish Environmental Protection Agency (EPA) of ignoring European Union (EU) NOx emission limits by granting an exemption to Irish Cement’s Limerick integrated plant. Limerick Against Pollution group alleges that the plant has been allowed a limit of 800mg/m3 despite a EU directive reducing the limit to 500mg/m3, according to the Limerick Post newspaper.
Austria: Data from the Austrian Cement Industry Association (VÖZ) shows that cement production rose by 7.4% year-on-year to 5.2Mt in 2018. The increase has been attributed to a construction boom. Sales of cement grew by 4.7% to Euro432m. Sales continue to increase at a similar rate in the first quarter of 2019 but this has slowed down in the second quarter.
The association has said that environmental investment more than doubled in 2018 to Euro45m. The local industry’s alternative fuels substitution rate was 82% and CO2 emissions fell by 0.8% to 521kg/t of cement.
South Africa: PPC says it plans to shut the kiln at its Port Elizabeth cement plant ahead of stricter requirements to the country’s emission standards. It is shutting down the kiln to meet new standards for NO2 and dust emissions on 1 April 2020, according to Reuters. Around 30 jobs are expected to be affected by the shutdown.
The cement producer’s revenue rose slightly year-on-year to US$736m in its financial year to 31 March 2019. Its profit nearly quadrupled to US$10.2m. Its cement sales volumes also rose slightly to 5.9Mt. Sales and earnings fell in South Africa due to a poor market but they grew elsewhere in Sub-Saharan Africa, notably in Rwanda and the Democratic Republic of Congo.
Japan: Taiheiyo Cement has set an 80% CO2 reduction target from cement production by 2050. It also plans to reduce its emissions from cement products by 20%. It aims to do this via a variety of means including energy-saving measures, promoting co-processing, lowering the clinker factor of its cement and CO2 capture technology. The cement producer started a pilot of a chemical absorption method on kiln exhaust gases at its Fujiwara plant in early 2019.
UltraTech Cement to exceed 25% green energy contribution to total energy consumption by 2021
20 June 2019India: UltraTech Cement aims to increase contribution of so-called ‘green energy’ to 25% of its total power consumption by 2021 from 10% at present. It also intends to raise its contribution of renewable energy to its total power consumption by five times in the next two years to 2021 to over 10%. By building capacity for renewable power the cement producer intends to become one of the largest users of renewable energy in the Indian cement sector.
In addition to renewable energy, the green energy contribution includes energy generated through waste heat recovery systems (WHR). During its 2019 financial year UltraTech commissioned 28MW of WHR systems to take its total generation from WHR to 8% of total power consumption. Further upgrades are expected to be completed in a phased manner by 2021, taking its WHR share to 15% of its total power requirement.
“To bring the cement sector in line with the Paris Agreement on climate change, UltraTech Cement’s annual emissions will need to fall by at least 16% by 2030. There are a number of solutions for reducing emissions associated with cement production as identified by the latest Low Carbon Technology Roadmap published by International Energy Agency (IEA) in partnership with Cement Sustainability Initiative (CSI). These solutions need to be deployed at scale to meet the decarbonisation challenge,” said K K Maheshwari, the managing director of UltraTech Cement.
UltraTech Cement has set a target to reduce its CO2 emissions by 25% from its 2005 – 2006 level by 2021. The company is also working on CO2 reduction strategies including energy efficiency, alternative fuels, WHR, renewable energy and reducing its clinker ratio.
Dust matters in India
12 June 2019There was a glimmer of good news visible through the Delhi smog this week with the launch of a market-based emissions trading scheme (ETS) for particulate matter (PM). A pilot has started at Surat in Gujarat. The scheme will apply to 350 industries in the locality and it will be scrutinised for wider rollout in the country.
China robustly started to tackle its industrial PM emitters a few years ago although the work remains on-going. In its wake India has increasingly made the wrong sort of headlines with horrifically high dust emissions. Delhi, for example, reportedly had PM2.5 emissions of over 440µg/m3 in January 2019. To give this some context, the World Health Organisation’s (WHO) annual upper guideline figure for safe human exposure is 10µg/m3. Research by the Financial Times newspaper suggested that more than 40% of the Indian population is subject to annual PM2.5 emissions of over 50µg/m3.
Air Quality Life Index (AQLI) research reckons that if India were able to meet its national PM2.5 standard of 40µg/m3 then its population would live 1.8 years longer or 4.3 years longer if it met the WHO guideline level. The current situation is an unnecessary tragedy. In strictly structural terms the country’s productivity is being thrown away by damaging the health of its workforce. For comparison amongst other major cement producing countries, AQLI data placed China’s PM2.5 emissions at 39µg/m3, Indonesia at 22µg/m3, Vietnam at 20µg/m3 the US at 9µg/m3. These figures cover all industries in different conditions and climates. If the US can do it, why not the others?
Back on trading schemes, the famous ETS at the moment is the European one for CO2 emissions. Similar schemes are slowly appearing around the world as governments look at what the European Union (EU) did right and wrong. For example, South Africa started up a carbon tax in early June 2019. Yet as the supporting documents by the Gujarat Pollution Control Board (GPCB) point out there have been a variety of ETS systems’ over the years. The US’s Acid Rain Program is generally seen to have achieved significant reductions in SO2 and NOx emissions although the National Emission Standards for Hazardous Air Pollutants (NESHAP) has continued this work. Chile even ran its own PM ETS in the 1990s although the outcomes have been disputed.
One problem with a CO2 ETS, and anthropomorphic or man-made climate change in general, is that it is intangible. Even if sea levels deluge major coastal cities, rising mean temperatures reduce agricultural yields and human populations contract sharply, people will still be arguing over the research and the causes. The beauty of a PM ETS is that if it works you can literally see and feel the results. A famous example here is the UK’s Clean Air Act in the 1950s that banished the fog/smog that London used to be famous for.
The Gujarat PM ETS is a pilot, the results of which will be considered by researchers from a number of US-based universities and the Abdul Latif Jameel Poverty Action Lab. Explicitly, the study plans to use a randomised control trial to compares its results against the command and control style approach used in the rest of the country. On the cement-side various Indian news stories have emerged as state pollution boards have increasingly started fining producers for emission limit breaches. Clearly the government is taking dust emissions seriously. Reduction is long overdue.
South Africa introduces carbon tax
04 June 2019South Africa: The government has introduced a carbon tax of around US$8/t for carbon dioxide-equivalent (CO2e) emissions. The carbon tax will initially only apply to scope 1 emitters in the first phase. The first phase will be from 1 June 2019 to 31 December 2022, and the second phase from 2023 to 2030. Large-scale tax-free emission allowances from 60 – 95% will be provided in the first phase. Industries such as cement or iron production will benefit from a basic threshold of 70%.
A review will be held before the second phase starts to measure progress. The treasury reinforced that the introduction of the carbon tax would not raise electricity prices due to tax breaks for renewable energy sources and credits for existing generation capacity.
Nigeria: Dangote Cement has published its first sustainability report following Global Reporting Initiative (GRI) standards. Key data from the report include a CO2 emissions per tonne of cementitious material of 687kg CO2/t across all operations. Its total CO2 emissions were 16.4Mt. In 2017 it reported estimated total CO2 emissions of 8.45Mt from its domestic operations. The cement producer had an energy consumption of 52M GJ 2018. It had a 49% production capacity utilisation rate at its Nigerian plants. The group said that it supported 37,000 direct, indirect and induced jobs in Nigeria.
Cement industry takes emissions seriously
22 May 2019Today is the first day of the Global FutureCem Conference taking place in Brussels, Belgium. The event is looking at how the cement industry can adapt to a low or zero carbon world. Although Global Cement is organising the event, it is clearly topical as two news stories this week demonstrate.
Firstly, the chief executive officers (CEO) from 13 US companies, including LarfargeHolcim, announced that they were lobbying the US government to enact business-led climate change legislation. The initiative, known as the CEO Climate Dialogue, included principles such as ‘significantly’ reducing US greenhouse gas emissions. This is shocking because, at face value, large-scale CO2 emitters like LafargeHolcim have the most to lose from more rigorous environmental regulations. What do they have to gain from doing this? This is like turkeys voting for Christmas!
Interpretations of why LafargeHolcim and others might want to do this could go in a few directions. Firstly, the intention might be fully plausible. These companies could genuinely want to combat climate change. Secondly, more cynically perhaps, leading demands for legislation puts the lobbyists in the room when change is actually made. Given the integral nature of concrete in modern construction this is not necessarily a bad thing. Environmentalists may want to ban building materials that create CO2 emissions but, until they can offer an alternative or convince people to accept reduced quality of life, then cement is the material of choice. Thirdly, leading change allows one to stay ahead of it or at least give the sector more time to react to it. The ‘turkeys’ may not want to vote for ‘Christmas,’ but perhaps ‘Christmas’ could be replaced with something else?
This latest initiative by the CEOs in the US has parallels with the creation of the Global Cement and Concrete Association (GCCA) in 2018. Like the current moves in the US, cement producers led the creation of the GCCA, to promote concrete as the sustainable building material of choice.
Meanwhile, Germany’s HeidelbergCement also announced this week that its CO2 reduction targets to 2030 have been assessed against the Science Based Targets initiative’s (SBTi) criteria. Its SBTi target is to reduce scope 1 greenhouse gas (GHG) emissions 15% per ton of cementitious material by 2030 from a 2016 base year. HeidelbergCement has also committed to reduce scope 2 GHG emissions by 65% per ton of cementitious materials within the same timeframe. The SBTi target follows HeidelbergCement’s previous goal of a 30% reduction in its specific net CO2 emissions by 2030 compared with 1990. It says it has achieved a reduction of 20% so far.
HeidelbergCement is a sustainability leader in the sector with various projects on the go including the Low Emissions Intensity Lime And Cement (LEILAC) consortium direct separation pilot project at the Lixhe cement plant in Belgium. Following SBTi is a continuation of this trend, albeit one that anchors it with a global consensus.
Coincidence perhaps but when the two largest non-Chinese cement producers start announcing sustainability stories like then the picture is changing. The questions at this point is how far will it go.
A full review of the 3rd Global FutureCem Conference will be published after the event. To find it and more information visit: http://www.globalcement.com/conferences/global-future-cement/introduction
