Waste tyres to be burned at Oman Cement
17 February 2020Oman: Oman Environmental Services Holding Company (Be'ah) has signed an agreement with Oman Cement Company, in which Be'ah will supply expired tyres to the cement producer for use as an alternative fuel.
The agreement was signed by Eng Tariq bin Ali al Amri, CEO of Be'ah, and Eng Salem bin Abdullah al Hajri, CEO of Oman Cement Company. Eng Hajri reported that the agreement will contribute to the national economy, diverting 30,000t of waste tyres from landfill.
Ministry of Environment permits tyre-burning by Cementos Cosmos
06 December 2019Spain: Brazilian-based Votorantim Cimentos’ subsidiary Cementos Cosmos has received authorisation for the combustion of tyres to fuel the kilns at its 1.6Mt/yr Toral de los Vados plant in León. Diario del León has reported that the government of Castile and León will complete bureaucratic procedures finalising the permit before 25 December 2019.
Continental conveyor belts used in Swedish road project
23 January 2019Sweden: Conveyor belts supplied by Germany’s Continental are being used in the Förbifart Stockholm road infrastructure project. HeidelbergCement’s aggregate company Jehander is using Continental steel cord conveyor belts at its Löten quarry near Stockholm to allow rubble from tunnelling to be reused for road construction. In addition, drilling machines from Epiroc are using Continental DrillMaster tyres to provide high cut resistance, good traction and stability.
Overall, around 5.5Mt of rock will be extracted to build the tunnels required for the new bypass. A series of conveyor belt systems are being used to transport the extracted rock to three temporary ports that have been set up for the project. The rubble is taken across the waterways by inland vessels from the construction site in Stockholm to Löten. The rubble is then reused as concrete, mostly for road construction, or it used for local construction.
Cementos Cosmos asks to burn tyres
21 December 2017Spain: Cementos Cosmos has stated its intention to ask the Castilla León Board for permission to burn tyres in the kiln at its plant in Oral Sarriana. The move has already been met with resistance from the local Bierzo Aire Limpio platform, which has raised concerns about the effects of tyre burning on the local agricultural sector as well as ‘the alarming rates of contamination, cancer and premature deaths in a region closed in by mountains.’
This is despite the plant already having permission to burn paper and plastic waste. The increase in alternative fuels, ideally up to a 70% thermal substitution rate, is intended to reduce the plant’s dependence on fossil fuels.
Lafarge Canada invests in monitoring systems to help fuels bid
29 November 2017Canada: As it awaits industrial approval from the Province to burn tyres at its Nova Scotia cement plant, Lafarge Canada says it has spent US$830,000 to install emissions monitoring systems. The company says its new equipment measures plant emissions such as sulphur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, oxygen, and total hydrocarbons every 10 seconds.
Rob Cumming, Lafarge's environment director, says the company's proposed one year pilot project at its Brookfield plant will allow it to gather the scientific evidence needed to assure the public that it is safe to use scrap tyres as a replacement for coal.
In October 2017, the Environment Department said it was reviewing the company's application and would make a decision on the project within 60 days. The project has drawn criticism from residents near the plant, environmental groups and Nova Scotia's NDP, which has called on the Liberal government to ban tyre burning.
Opposition political party backs tyre burning ban in Nova Scotia
04 October 2017Canada: The New Democratic Party has called for a ban of burning tyres in Nova Scotia. The opposition political party held a news conference with opponents of the government's decision in July 2017 to approve a one-year pilot project allowing Lafarge Canada to burn tyres for energy at the company's Brookfield cement plant, according to the Canadian Press newspaper. No tyres have been burned at the plant so far as the cement producer waits for industrial approval of the project from the provincial government.
Mark Butler of the Ecology Action Centre said the government’s decision was based on a Dalhousie University engineering study that was too narrow in its focus and wasn't peer reviewed. However the government has said that it used several technical studies to inform its decision. A group of local residents also started legal action in August 2017 on the grounds that the project violated the province's Environment Act.
Lafarge Canada to test burning tyres at its Brookfield plant
30 September 2016Canada: Lafarge Canada has started a partnership with Dalhousie University researcher Mark Gibson to test tyre-derived fuel on an industrial scale at the Brookfield cement plant in Nova Scotia. Working under a Natural Sciences and Engineering Research Council of Canada (NSERC) Discovery Grant, this initiative will research the adoption of low carbon fuels in the cement industry. The research will continue the partnership between Lafarge Canada and Dalhousie's Faculty of Engineering.
"My students and I are very pleased to see this work enter the real world. Based on our research, we expect to see significant reductions in greenhouse gas emissions from the Brookfield cement plant and thereby help Nova Scotia move one step closer to a low carbon economy," said Gibson. He added that the use of tires will also reduce NOx emissions. In 2015, Gibson and his team published a report entitled ‘Use of scrap tyres as an alternative fuel source at the Lafarge cement kiln, Brookfield, Nova Scotia.’
Due to different initiatives including previous work with Dalhousie's Faculty of Engineering, the Brookfield plant has substituted alternative fuels for conventional ones by using front-end burner injection in its kiln. The plant is expected to reach a substitution rate of up to 30% by the end of 2016. Following the test using tyres the cement producer expects to use 15% of its fuel requirements from 450,000 tyres per year, or just under half the amount of tyres generated in Nova Scotia. The project proposal will be explained in further detail at a Public Meeting planned for 20 October 2016 in Brookfield.
Ireland: Irish Cement is planning to cut the amount alternative fuels it intends to co-process at its Limerick cement plant to 90,000t/yr. The cement producer withdrew its initial planning application in March 2016 but has resubmitted a new application with a lower amount of alternative fuels, according to the Limerick Leader newspaper. It now aims to burn half of the original amount that was originally requested.
It originally announced its Euro10m plan to co-process alternative fuels including tyres at the plant in December 2015. The investment is intended to create 40 jobs. However, local citizens have opposed the plans with over 450 people signing a petition against the development.
Irish Cement defers plan to burn tyres at Limerick plant
21 March 2016Ireland: Irish Cement has deferred its plan to co-process tyres at its Limerick cement plant. Planning was lodged in late February 2016, according to the Irish Examiner. However a spokesman for Irish Cement said that the company had noted a few days previously that the planning application had not been made available for public inspection, due to a ‘procedural’ matter. They added that the company was working with the Limerick City and Country Council to resolve the issue.
Local Green Party candidate James Gaffney raised concerns about the plant upgrade in local press in mid-March 2016. He alleged that no public consultation was being carried out on the plant’s plans and that the application was being fast-tracked. Irish Cement denied these claims.
Irish Cement announced its plan to burn alternative fuels at its Limerick plant in December 2015.
Khyber-Pakhtunkhwa Environmental Protection Agency defers approval for tyre-derived fuel plant at Bestway Cement
29 February 2016Pakistan: The Khyber-Pakhtunkhwa Environmental Protection Agency (EPA) has deferred the approval for setting up a tyre-derived fuel (TDF) plant at the Bestway Cement plant in Farooqia. The decision has been left by the EPA to consent from the local community, according to local press.
EPA Director General Dr Bashir Khan said at a public meeting that unless local residents were satisfied, Bestway Cement would not be issued a no-objection certificate. Residents have cited dust, smoke, noise and water pollution as reasons to object against the proposed plant. Qamar Hayat, a local activist, said that locals would allow the EPA to approve the TDF plant when they were guaranteed pollution would be monitored and that health hazards and property losses would be checked.
