Hungary: Italy-based Entsorga has completed the installation of an automated alternative fuel (AF) line at a Hungarian cement plant. The plant is believed to be Nostra Cement’s 1.0Mt/yr integrated Kiralyegyháza cement plant, which in early 2020 received an AF fuel store expansion aimed at bringing AF substitution rates to 80% from 60%. The upgrade consists of an Entsorga Spider crane and Pelican power system which will be able to maintain a continuous feed to the plant’s calcination system 24 hours a day.

Entsorga CEO Francesco Galanzino said, “Bringing a commission to a successful conclusion in the middle of the maximum intensity period of the coronavirus crisis has been a great satisfaction. The cement plant will make significant savings in CO₂ emissions.”

Spain: A 25% alternative fuel (AF) substitution rate has accounted for a 9650t reduction in CO₂ emissions at Cementos Cosmos’ 0.7Mt/yr Oural, Galicia plant, lowering the specific CO2 emissions of its clinker by 45kg/t. A main constituent of the AF mix was olive stones. Cementos Cosmos Oural plant managing director Jaime Santoalla said, “At Cementos Cosmos, we accept our responsibility to meet the global objectives of reducing greenhouse gas emissions.”

Ireland: The Environmental Protection Agency (EPA) has postponed a four-day hearing over Irish Cement’s alternative fuel (AF) licence application, scheduled for May 2020, to an as yet unspecified date due to the coronavirus. Under the terms of the proposed licence, Irish Cement will be able co-process a maximum of 90,000t/yr of refuse-derived fuel (RDF), including tyres, in the single dry line of its 1.0Mt/yr Mungret plant in County Limerick. The EPA said that emissions from operations under the terms of the licence ‘will meet all required environmental protection standards.’

Irish Cement received its preliminary licence to burn refuse-derived fuel (RDF) in September 2019. The move attracted local resistance, with 4500 people participating in a protest on 5 October 2019.

The EPA has said that it will give all relevant parties notice ‘well in advance’ of the date of the rescheduled hearing, which will take place after the government lifts the country’s coronavirus lockdown. On 14 April 2020 County Limerick had 234 coronavirus cases out of an Irish total of 10,647.

Ireland: The Environmental Protection Agency (EPA) has scheduled a four-day oral hearing in which it will review Irish Cement’s application for a permanent licence to co-process a maximum of 90,000t/yr of tyres and other waste materials as fuel in the single dry kiln of its 1.0Mt/yr Limerick plant in County Limerick. Irish Cement received its preliminary licence to burn refuse-derived fuel (RDF) in September 2019. The Irish Times newspaper has reported that 5000 local residents have since petitioned the EPA against permitting the practice, including ex-Irish rugby international Paul O’Connell and a former Love Island contestant.

The EPA said that emissions from operations conducted in accordance with the proposed licence ‘will meet all required environmental protection standards.’

Vietnam: 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.’

Italy: Federbeton, the Italian cement and concrete producers’ association, has complained of ‘bureaucratic and regulatory’ obstacles causing Italy to lag behind other European countries in its use of refuse-derived fuel (RDF) in cement production. Statistics from the Italian Technical and Economic Cement Association (AITEC) show a net AFD substitution of 0.39Mt in 2018, corresponding to 20% of cement fuels burned in Italy. This represents a year-on-year increase of 2.4% from 0.38Mt (17%) in 2017, but lags behind the European annual average of 46%. Peak substitution was in neighbouring Austria, where 79% of cement fuel was refuse-derived. “Our investments in environmental technologies are bearing fruit,” said Antonio Buzzi, coordinator of Federbeton’s Environment and Circular Economy Committee. “We are ready to use larger quantities of alternative raw materials, but continue to pay for these obstacles.”

ANSA has reported that in 2018, Italian cement producers achieved a year-on-year decrease in net CO₂ emissions of 8.9%. Dust levels also decreased by 15.4% compared to 2017.

Egypt: According to Reuters, Arabian Cement Company has commissioned new alternative fuel processing machinery at its plant in Suez.

The state-of-the-art FLSmidth HOTDISC^TM allows Arabian Cement's plant to rely completely on coal and alternative fuels to run its operations. Moreover, it enables the plant to operate its kilns using alternative fuel materials directly, without the need to pre-treat them. Arabian Cement now has a designed fuel mix of 70% coal and 30% alternative fuels. The alternative fuel that will be used will be a mixture of agricultural wastes, municipal sludge and refuse-derived fuels (RDF). Alternative fuel use is expected to result in around 60,000t/yr of reduced CO₂ emissions.
