Vietnam: 20 factories in Quang Ninh, Thanh Hoa, Quang Nam and Thua Thien Hue provinces will be subject to a new carbon tax in a pilot project. The Ministry of Agriculture and Rural Development has started to put the programme into action following approval from Prime Minister Nguyen Xuan Phuc, according to the Vietnam News Agency Bulletin. The pilot project will start in 2020 and run until the end of 2021.
The scheme will include 11 cement companies and nine power plants. Cement producers and traders will be charged US$0.09/t of clinker, equivalent to US1.35/t of CO2. The tax will also increase electricity costs for cement producers. It is expected to increase the production cost at plants by 0.29%.
Nguyen Van Vu, head of Finance and Planning Department under Vietnam Administration of Forestry (VAF), said that the tariff was lower than the World Bank’s Forest Carbon Partnership Facility pledge to pay for emission reduction efforts in North Central Region of US$5/t of CO2. The provinces running the tariff are expected to generate around US$7.4m/yr. Most of this revenue will be accrued in Quang Ninh, followed by Thanh Hoa, Thua Thien Hue and Quang Nam.
Belgium: Australia’s Calix says the Low Emissions Intensity Lime And Cement (LEILAC) consortium has successfully demonstrated CO2 separation with more than 95% purity at its pilot unit at HeidelbergCement’s cement plant in Lixhe. Technology provider Calix said that preliminary test runs have been completed on the pilot. The technology concept has been shown to work on both lime and cement meal, with calcination near to target levels and high purity CO2 successfully separated at the top of the reactor although not yet at full design capacity.
It added that it was still working on fixing commissioning issues. Testing will run until the end of 2020 to assess the risk of potential longer-term issues such as tube health and process robustness. In parallel, planning has commenced on the next scale-up of the technology, including conceptual design and engaging funding consortia.
Lafarge Canada launches carbon capture project
26 July 2019Canada: Lafarge Canada has launched the first phase of its CO₂MENT project. The objective is to build a full-cycle solution to capture and reuse CO2 from a cement plant. The project is a partnership between Lafarge Canada, Inventys and Total.
“LafargeHolcim is committed to reducing CO2 emissions and we are excited to join forces with Inventys and Total through Project CO₂MENT. We hope to discover ways to capture emissions from our production processes and reuse them in our products, advancing a circular economy even further than today. The recent launch of the new lower carbon fuel (LCF) system at our Richmond plant aims to make the facility the most carbon efficient cement plant in Canada,” said René Thibault, Region Head North America for LafargeHolcim.
Over the next four years, Project CO₂MENT will demonstrate and evaluate Inventys’ CO₂ Capture System and a selection of LafargeHolcim’s carbon utilization technologies at its Richmond cement plant in British Columbia. The project has three phases and is expected to be fully operational by the end of 2020. Subject to the pilot’s success, the vision is to scale up the project and explore how the facility can be replicated across other LafargeHolcim plants.
During the first phase the partners will work on purifying the cement flue gas in preparation for CO2 capture. The second phase will focus on the separation of CO2 from flue gas using a customised for cement version of Inventys’ carbon capture technology at pilot scale. As part of the final phase, the captured CO2 will be prepared for reuse and support the economical assessment and demonstration of CO2 conversion technologies onsite, such as CO2 injected concrete and fly ash.
Germany: HeidelbergCement’s specific CO2 net emissions per tonne of cementitious material fell by 1.4% year-on-year to 599kg CO2/t in 2018 from 608kg CO2/t in 2017. Despite this its absolute gross CO2 emissions increased by 3% to 76.7Mt from 74.2Mt as clinker, cement, aggregate and concrete sales volumes all grew in 2018. The group has published the data in its Sustainability Report for the 2018 financial year.
“Cutting our CO2 emissions and handling natural resources considerately are priorities for all our business lines,” says Bernd Scheifele, chairman of the managing board of HeidelbergCement. "We focus primarily on the development of sustainable products and the implementation of concrete measures at plant level in order to achieve our sustainability goals.” The company has set itself the target of a 30% reduction in its specific net CO2 emissions per tonne of cement by 2030, compared with 1990. HeidelbergCement says it intends to realise its vision of CO2-neutral concrete by 2050 at the latest.
Other figures of note in the report include an alternative fuels substitution rate of 21.7% in 2018 compared in 20.8% in 2017. NOx, SOx and particulate matter emissions all fell. However, total water withdrawal rose by 8% to 65.4Mm3 from 60.4Mm3 although water consumption fell.
UK: The Institutional Investors Group on Climate Change (IIGCC) has called on European building materials companies to take steps to fight climate change or face commercial extinction. Recommended changes from its new ‘Investor Expectations of Companies in the Construction Materials Sector’ report have been sent to the heads of LafargeHolcim, HeidelbergCement, CRH and Saint-Gobain. The report informs investor engagement with other construction material firms on the initiative’s global list of 161 focus companies. Investment bodies in the group represent US$2Tn in assets, assets under management and under advice.
“The cement sector needs to dramatically reduce the contribution it makes to climate change. Delaying or avoiding this challenge is not an option. This is ultimately a business-critical issue for the sector,” said Stephanie Pfeifer, the chief executive officer (CEO) of the IIGCC. “Major economies such as the UK and France are increasingly adopting economy-wide net zero emission targets. The cement sector needs to get ahead of the profound transformation their sector faces by addressing barriers to decarbonisation in the short- to medium-term if companies are to secure their future.”
Key details set out in the ‘Investor Expectations’ report include becoming carbon neutral by 2050. Companies are expected to set short, medium and long-term science-based targets to reach this goal. Building material companies should be public policy transparent and advocate for the Paris Agreement, they should implement a ‘strong’ governance framework assigning specific responsibility for climate change to a board committee or board member and they should provide enhanced corporate disclosure in line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).
The IIGCC recognised the steps HeidelbergCement in particular has taken in already having committed to meeting key aspects of the investor expectations it has outlined. CRH, LafargeHolcim and Saint-Gobain have been encouraged to follow suit, given the ‘significant’ role they play as European-based multinationals. The group also praised the ambitious targets set by India’s Dalmia Cement to become carbon negative by 2040.
Japan Coal Energy Center, GreenOre Clean Tech and others sign deal on CO2 capture and utilisation project in Wyoming
22 July 2019US: The Japan Coal Energy Center (JCOAL), GreenOre Clean Tech, Columbia University and Wyoming Infrastructure Authority (WIA) have entered into a memorandum of understanding (MOU) to test carbon utilisation and recycling technology. GreenOre Clean Tech, using technology under license from Columbia University, will use testing space at the Integrated Test Center (ITC) near the Dry Fork Station coal-fired power station in Gillette, Wyoming. Calcium carbonate produced through CO2 mineralisation could then potentially be used for aggregates, concrete production or in paper production. The test will be funded by JCOAL with additional support from project partners.
The State of Wyoming and JCOAL have been working together since 2016, when they signed an initial MOU committing to cooperation in coal research and development of technologies and coal trade. JCOAL operates under the supervision of the Ministry of Economy, Trade and Industry of Japan and is supported by more than 120 member coal-related businesses, including Kawasaki Heavy Industries, Mitsubishi Hitachi Power Systems, Nippon Steel and Toshiba. Kawasaki is scheduled to test its solid sorbent capture technology at the ITC beginning in 2021.
Refuse-derived legislation in the Netherlands?
17 July 2019The UK waste fuels industry is facing potential challenge from changing Dutch environmental legislation. As part of its new National Climate Agreement the government in the Netherlands is considering imposing a tariff of Euro32/t on imported refuse-derived fuel (RDF) from the start of January 2020. It also wants to add a CO2 tax of Euro30/t on industrial emitters from the start of 2021.
This is bad news for the UK’s waste export market because 1.28Mt or 44% of exported waste fuels from the UK in 2018 went to the Netherlands. The majority of this was RDF. That was more than the next two biggest destinations, Sweden and Germany, combined. Andy Hill of Cynosure Partners summed up the UK situation in the June 2019 issue of Global Cement Magazine when he said, “The UK generates more far more waste than it has landfill, recycling and alternative fuel capacity combined. Quite simply, that’s why the UK exports and has become a leading force in Europe in terms of RDF and solid recovered fuel (SRF) exports.”

Waste management companies and their representative associations on both sides of the North Sea are not taking this terribly well. Robert Corijn, chair of the RDF Industry Group, a European waste organisation, summed up his members response by pointing out both the environmental cost of the new legislation and the risk to jobs in the UK. “RDF export forms a vital and flexible part of the UK’s waste management system, supporting over 6800 additional jobs in the UK, and saving over 0.7Mt/yr CO2e emissions.” Robert Loos of the Dutch Waste Management Association made a similar response questioning what exactly the Dutch government was attempting to achieve.
Steve Burton, one of the directors of UK-fuels producer Andusia, went further by saying that the Dutch had proposed the move on environmental grounds because it has an incineration capacity of 8Mt/yr but produces only 6Mt/yr of waste. “So they think that by setting a tax it will significantly curtail how much gets incinerated in the Netherlands and thus produce less CO2. All very sensible if you consider CO2 in isolation in your own country. However, the Dutch Government aren’t looking at the bigger picture…” He then went on to point out that the RDF would then either get burnt elsewhere or landfilled resulting in no overall CO2 emissions reduction. His further assessment, which you can read here, goes on to speculate amongst other things that Dutch Energy for Waste (EFW) plants could end up having to cut their gate fees by more than the import tariff in order to keep running. The state-owned EFW plants would then made a loss for the tax payers until the market stabilised. It should be noted that the data from the Environment Agency indicates that Andusia exported just under 38,000t of RDF to the Netherlands in 2018.
The more prickly issues of using waste fuels may prove tricky for Dutch legislators. Corijn’s distinction above of using CO2e for the savings from RDF usage is important in this argument since burning RDF and alternative fuels, either for generating energy or making cement, still releases CO2. In the European Union (EU) it’s the biomass fraction of RDF that’s important for the Emissions Trading Scheme (ETS) and the like because biomass emissions are counted as carbon-neutral. Remove this effect and the benefit of waste fuels are more to do with the waste hierarchy and reusing materials rather than leaving them to rot and release methane, a gas with a more potent global warming effect than CO2. Despite this, at face value, importing rubbish and then burning it to release yet more unwanted CO2 may seem nonsensical to the parliamentarians. Perhaps the other thing they should consider is that waste-derived fuels are manufactured products to set specifications. On-going arguments around the world about the developed world ‘exporting its rubbish’ frequently ignore this point.
Since the new Dutch National Climate Agreement is currently at the proposal stage it has a long way to go before it becomes law. First it has to be turned into legislation and then this has to be approved by the Dutch Parliament. As indicated so far the waste management industry will continue to fight its corner with vigour.
France: Lafarge France has launched its Lafarge 360 initiative. The scheme aims to aid specifiers, contractors and builders make low-carbon structures through reducing CO2 emissions, preserving natural resources and responsible innovation. It will start the initiative by proving a Lafarge 360 score on its associated digital platform to allow customers to assess the environmental impact of Lafarge’s products. By providing a rating of A to D the tool will offer information on the concrete types.
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.
US: Hawaii’s Department of Transportation plans to use carbon-injected concrete for its new projects. This will include a new structure to protect a highway tunnel from rockfalls, according to Reuters. The Department of Transportation was testing CO2-injected concrete on an access road project with CarbonCure Technologies in May 2019. The latest decision follows a resolution by state legislators that city administrators ‘consider’ using CO2-injected concrete in city and county infrastructure where concrete is used.
In late June 2019 CarbonCure announced that its had formed a partnership with HC&D Ready Mix, a local concrete producer, to use its CO2-injected concrete process. It is the second deal with a concrete producer in the state that CarbonCure has arranged.
