Spain’s cement producers unite against coronavirus waste
26 March 2020Spain: Members of the Spanish cement association Oficemen have offered help to the government in the disposal of medical waste contaminated with the coronavirus, for which any kiln line with the right alternative fuel processing capabilities will be made available. Minister for Industry Reyes Maroto said that the plants will be used for waste’s elimination ‘only insofar as companies can continue operating.’
Huaxin Cement helps dispose of coronavirus waste
25 February 2020China: Huaxin Cement says that it has disposed of 55t of medical waste from coronavirus-infected hospitals in Wuhan province at its 3.4Mt/yr Yangxin cement plant in Hubei province. Xinhuanet News has reported that the plant’s precalciner and rotary kiln have safely processed the batch, from its delivery in sealed trucks, through the combustion of the waste and its packaging, into cement.
Vicem and FLSmidth target sustainable cement production
10 February 2020Vietnam: The Vietnam National Cement Corporation (Vicem) and Denmark-based supplier FLSmidth have announced a cooperation agreement with the aim of radically reducing the greenhouse gas emissions from cement production and improving air quality. The cooperation will consist of Vicem implementing solutions pioneered by FLSmidth. FLSmidth said that a key focus of the cooperation will be Vicat’s use of ‘municipal and other waste streams as alternative fuel sources,’ with the aim of achieving 100% substitution using FLSmidth solutions, in accordance with FLSmidth’s ambition ‘to enable cement companies to operate with zero emissions by 2030.’
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.
Cemex to convert Gádor cement plant site for renewables, waste recycling and concrete
11 January 2019Spain: Cemex has signed a Euro117m deal with the local government to convert the land used by the Gádor cement plant in Almeria for use by new projects. These will include projects in solar and wind power generation, waste fuel production from plastics and biomass and a new concrete batching plant, according to Teleprensa. The initiative is intended to create around 400 jobs.
The cement producer has also signed a similar agreement for its Lloseta in Baleares. The company announced in mid-October 2018 that it was planning to close the two plants due to reduced demand for cement and mounting European CO2 emissions regulations.
Walking the plastics tightrope in Europe
17 January 2018This week’s Plastics Strategy from the European Commission (EC) presents the cement industry with a narrowing target. If the Plastics Strategy is successful it will prevent plastics waste altogether. This will then eliminate the key calorific content of refuse-derived fuels (RDF) and disrupt co-processing supply chains at cement plants across the continent. If it is too lax then dumping plastics in landfill could become more economically viable, also changing the market dynamic. Neither extreme looks likely at this stage but the European cement industry needs to make its views known.
Cembureau, the European cement association, has done just that today with the publication of a position paper on the subject. It conveniently ignores the top two tiers of the waste hierarchy – prevention and re-use – but it does recognise that ‘high quality recycling’ is the preferred option. This is followed by the target of its lobbying: protecting co-processing. Make no mistake, this is supporting industrial behaviour change with solid environmental benefits. Its areas for policymakers to focus on include protecting co-processing: a ban on landfill; linking energy recovery to recycling; concentrating on the legislation; thinking about material lifespan sustainability benefits; and helping minimise the investment costs for processing facilities.
Providing cool heads prevail, the importance of co-processing plastics as part of any realistic plastics strategy seems unlikely to change any time soon. What’s more likely to be the real target for Cembureau is standardising measures on collection, sorting and material recovery across the European Union (EU). For example, as this column has reported twice in 2017 (GCW288 and GCW324), the issues with waste disposal legislation in Italy have led to various problems in the sector. Waste collectors found it easier to export RDF to Morocco from Italy rather than use it locally in 2016. The slag industry has also reported similar issues with reuse in Italy. The consolidation of the local cement industry following the takeover of Italcementi and Cementir by HeidelbergCement and of Cementizillo by Buzzi Unicem should present a more unified industry approach towards alternative fuels. Backup from the EC could solve the other half of the alternative fuels puzzle in Italy and help to deliver serious change. Ecofys data from 2014 showed the EU co-processing average rate as being 41%, with six countries – Ireland, Portugal, Spain, Bulgaria, Italy and Greece – having rates below 30%.
Vagner Maringolo of Cembureau outlined the market opportunities for waste uptake at cement plants at the 11th Global CemFuels Conference that took place in Barcelona in February 2017. He started by revealing that plastics represented over 40% of the total share of alternative fuels used in the EU in 2014. A ban on landfilling municipal waste was expected to boost the supply of RDF and a Cembureau/Ecofys study on the market potential of alternative fuels concluded that around 10Mt of waste was co-processed in cement kilns in the EU28 in 2015. This represented around 2% of total combustible waste each year but it represented 10% of all of the energy recovery from waste in the EU. In other words co-processing plastics waste offers a very attractive means for the EU to meet its sustainability targets.
However, before Cembureau and the cement industry starts popping the (reusable) champagne corks, consider the wider picture. China has banned imports of foreign waste in 2018 including RDF from the UK, a major exporter. Unless new markets are found this may impact the price of RDF in Europe. Brexit is another example how of European waste markets might be disrupted in the medium-term. Cement producers want a steady supply of cheap fuels but if the providers can’t make enough money from their products then the market will fail. The tightrope for Cembureau to walk with plastics is to promote RDF use and secure its supply. Persuading the EC to support this may involve some wobbling along the way.
Cembureau releases position paper on plastics strategy
17 January 2018Belgium: Cembureau, the European cement association, has published a position paper outlining its stance European Commission’s plastics strategy. The association wants policymakers to ensure any plastic waste that has a calorific value that can be recovered as a fuel source is not landfilled. At present there are differences in waste management policies across the member states of the European Union.
Other points that Cemburea wants to highlight include: a ban on landfill of recoverable and recyclable waste; recognition that cement plants can treat different waste streams such as plastics and simultaneously recycle them as material in the manufacturing process of cement and recover them as energy; the specific relevance that co-processing offers the unique opportunity of a simultaneous energy and material recovery; and the potential to minimise investment costs in dedicated facilities.
In January 2018, the European Commission published a dedicated Plastics Strategy as part of the Circular Economy package. The strategy indicates that there is currently a low rate of recycling or reuse of plastics with most of it going to landfill or used in incinerators.
Not in my cement kiln: waste fuels in Morocco
08 February 2017Last week’s Global CemFuels Conference in Barcelona raised a considerable amount of information about the state of the alternative fuels market for the cement industry and recent technical advances. One particular facet that stuck out were reports from cement and waste producers, from their perspective, about Morocco’s decision to ban imports of waste from Italy in mid-2016. The debacle raises prickly questions about how decisive attempts to reduce carbon emissions can be.
Public outcry broke out in Morocco in July 2016 over imports of refuse derived fuel (RDF) imported from Italy for use at a cement plant in the country. At the time a ship carrying 2500t of RDF was stopped at the Jorf Lasfar port. Local media and activists presented the shipment in terms of a dangerous waste, ‘too toxic’ for a European country, which was being dumped on a developing one. Public outcry followed and despite attempts to calm the situation the government soon banned imports of ‘waste’.
What wasn’t much reported at the time was that RDF usage rates in Europe have been rising in recent years and that the product is viewed as a commodity. As Michele Graffigna from HeidelbergCement explained at the conference in his presentation, its subsidiary Italcementi runs seven cement plants in Italy but only two of them have the permits to use alternative fuels like RDF. Italy also has amongst the lowest rates of alternative fuels usage in Europe, in part due to issues with legislation. This is changing slowly but the company has an export strategy for waste fuels from the country at the moment. Italy’s largest cement producer wants to use waste fuels in Italy but it can’t fully, so it is exporting them so it (and others) is exporting them to countries where it can.
In the Waste Hierarchy, using waste as energy fits in the ‘other recovery’ section near the bottom of the inverted pyramid, but it is still preferable to disposal. Waste fuels may be smelly, unsightly and have other concerns but they are a better environmental option than burning fossil fuels. HeidelbergCement engaged locally with media and local authorities to try and convey this. It also arranged visits to RDF production sites in Italy and German cement plant that use RDF to present its message. Looking to the future, HeidelbergCement now plans to focus on local waste production in Morocco with projects for a tyre shredder at a cement plant and an RDF production site at a Marrakesh landfill site in the pipeline. Graffigna didn’t say so directly, but the decision to focus on local waste supplies clearly dispenses with historical and cultural baggage of moving ‘dirty’ products between countries.
In another talk, at the conference Andy Hill of Suez then mentioned the Morocco situation from his company’s angle. His point was that moving waste fuels around can carry risks and that a waste management company, like Suez, knows how to handle them. It is worth pointing out here that Suez UK has supplied solid recovered fuel (SRF) to the country so it has a commercial interest here. He also suggested that despatching a bulk vessel of waste to a sensitive market did not help the situation and that it heightened negative publicity.
Morocco’s decision to ban the import of waste fuels in mid-2016 is an unfortunate speed bump along the highway to a more sustainable cement industry. It raises all sorts of issues about public perceptions of environmental efforts to clean up the cement industry and where they clash with commercially minded attempts to do so by the cement producers. A similar battle is playing out in Ireland between locals in Limerick and Irish Cement, as it tries to start burning tyres and RDF. These are not new issues. Meanwhile in the background the amendment to the European Union Emissions Trading Scheme draws close with a vote set for mid-February 2017. It could have implications for all of this depending on what happens. More on this later in the month.
A Tec commissions Rocket Mill in Wiener Neustadt
30 November 2016Austria: A Tec has commissioned a Rocket Mill RM 2.50 for ASA at its waste treatment plant in Wiener Neustadt. The mill has a capacity of 7 – 40t/hr and is equipped with two grinding chambers, which can be independently loaded. Each one has a main drive with 315kW. Due to the grinding technology, it also has an additional drying effect of approximately 10%. The mill is designed to produce refuse-derived fuels (RDF) with an output size of 5 - 80mm from pre-sorted and shredded household and commercial waste. It was principally built at A Tec’s plant in Eberstein.
