Ireland: Residents of Limerick protested on 10 and 11 March 2017 against Irish Cement’s plans to burn waste solvents and used tyres at its plant in Mungret. In response, Irish Cement stated that it is the only cement plant left in the country that uses solely fossil fuels and that it needs to use waste fuels to reduce costs if it is to keep the 84 jobs at the plant.

Canada: 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.

Update on Oman

It’s been an interesting month for the cement industry in Oman with the announcement of various producer projects and a recent market report predicting steady growth in the country.

A late August 2016 sector report from Al Maha Financial Services concluded that government-backed infrastructure projects in the country have pushed cement demand over the production capacity of the two leading local cement producers, Oman Cement and Raysut Cement. The report tempered the good news though with fears that excess production capacity from neighbouring producers in nearby countries would continue to lower prices in Oman. This matches the situation Global Cement found when it visited Oman Cement’s plant in early 2015. Such was the demand-production gap that this producer sometimes imported clinker to keep its supply constant when it shutdown its kiln for maintenance.

Cement production capacity in Oman currently stands at 8.81Mt/yr according to Global Cement Directory 2016 data. The major cement producers hold most of the local market with Oman Cement’s 4.2Mt/yr plant at Rusayl and Raysut Cement’s 3Mt/yr plant at Salalah.

Raysut Cement has announced progress on a number of local projects throughout 2016 including launching a new 20,000t silo at Salalah in May 2016, building a new terminal at the Port of Duqm due to open by the end of the third quarter of 2016, installing a new 150t/hr rotary packing plant with auto truck loader for expected commissioning by the end of October 2016 and it is currently upgrading its gas supply station at Salalah, also to give cement production a boost.

This last project is of particular interest because when Global Cement visited Oman Cement the staff at the Rusayl plant were concerned about the rapidly rising price of natural gas. The plant used gas as its primary fuel and at the time of the interview in January 2015 they were considering diversifying into alternative fuels such as a tyres or using local coal instead. The issue also received a mention in the company’s first quarter report, where it attributed the rise in gas prices to a 26.8% hit in its operational profit taking it down to US$15.6m in the first quarter of 2015.

Meanwhile, both Raysut Cement and Oman Cement are in the process of building a cement plant together at Al Duqm. The latest news on this joint venture emerged in mid-August 2016 when the companies announced that they had registered Al Wusta Cement as the company designated to carry out the project. So far the plant is at the feasibility study stage with further progress to be released at a later date.

Operating in a full-capacity environment will be a dream to many cement producers around the world. However, it is not without its pitfalls from input issues such as gas supply or fighting off external competition who may want a piece of the pie. Oman's construction industry is expected to see growth of 3.4% to US$5.74bn in 2016 backed by government spending. It is there for the taking for the local producers.

US: The Essroc cement plant in Speed, Indiana has lots its appeal to burn alternative fuels. Local government officials have decided that the plant will have to apply for rezoning to order to burn hazardous waste, comprising solvents, paints and other chemicals along with coal, according to the Washington Times newspaper.

“I’m disappointed in the decision, but I’m confident that we’ve got other means to obtain the required authorisation to continue with the project,” said Jeremy Black, the plant manager.

Local residents who are suing the plant have accused Essroc of misleading them regarding which fuels the company intends to burn. Essroc have denied the claim.

Ireland: Irish Cement’s plans to use used tyres as an alternative fuel at its plant in Limerick, Munster, have been delayed, after more than 1000 local residents signed a petition to present to the Environmental Protection Agency (EPA).

Local Labour councillor Joe Leddin said the sheer number of submissions is, ‘testament to the huge anxiety and worry of residents.’ An EPA spokesman confirmed it is one of the highest responses it had ever received for any application. The petition now means that no decision is likely to be made on the plans until the start of 2017.

Irish Cement has previously stated that the public’s concerns are disproportionate. The tyres will be burnt at such high temperatures, that the tyres will be completely consumed and pollution will be minimal.

Portugal: Cimpor has appealed a judgement by the Supreme Administrative Court cancelling permits to burn alternative fuels at its Souselas cement plant. The North Central Administrative Court cancelled the environmental licences, originally granted by the former Environment Minister Nunes Correia, in March 2016.

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.

Ecuador: Union Andina de Cementos (UNACEM) has been recognised as an eco-efficient company by the Ministry for the Environment. The certification is given to companies that have demonstrated environmentally friendly production. Unacem submitted four case studies to qualify for the certification, according to La Hora. These included examples of using slag to produce clinker and co-processing alternative fuels like palm kernel shell and waste oils.

Ireland: 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.

US: The GCC (Grupo Cementos de Chihuahua) Dacotah cement plant in Rapid City has started a US$90m upgrade. The project will include new kiln equipment, provision for co-processing alternative fuels and improvements to the plant’s shipping operations, according to the Rapid City Journal. The upgrade will increase the plant’s cement production capacity to 1.3Mt/yr.

The plant was founded by the South Dakota state in the 1920s and sold into private ownership in 2001. It employs 130 full-time employees. The upgrade is expected to create 13 new full-time jobs.
