UK: RDF Industry Group has convened a refuse-derived fuel (RDF) industry working group to meet on a fortnightly basis to discuss the sectoral impacts of coronavirus. The Group said that it ‘is working with competent authorities to ensure the free flow of RDF is maintained.’ It acknowledged that RDF supply is essential to European cement production, adding, “The flow of RDF from the UK to off-take facilities in Europe is continuing, with the industry overall functioning well.”

Germany: Red Dot has awarded Vecoplan its Red Dot Design Award for the new Vecoplan VEZ 3200 pre-shredder for refuse-derived fuel (RDF). The prize ‘acknowledges the aesthetics and workmanship’ of the product, as well as its ergonomiocs and functionality. Vecoplan CEO Werner Berens said, “The design impacts on the machine construction, making the shredder easier to handle for operators.”

Brazil: Votorantim Cimentos earned revenues of US$2.47bn in 2019, up by 3.0% year-on-year from US$2.39bn in 2018. Its earnings before interest, taxation, depreciation and amortisation rose by 1.1% to US$513m from US$507m in 2018. Throughout the year, the company says that it paid off approximately US$570m of debt and contracted with a syndicate of banks for a new committed credit facility (CCF) for its alternative fuel substitution and CCF reduction initiatives of US$55.1m, due in August 2024.

On 30 March 2020 Votorantim Cimentos donated US$5.5m to fighting the effects of the coronavirus in Brazil.

Japan: Taiheiyo Cement has set out the measures by which it aims to achieve its July 2019 target to ‘reduce net CO₂ emissions per unit of cement production’ by 80% between 2000 and 2050. The measures consist of: the introduction of energy-saving equipment, the promotion of alternative fuels (AFs) and the development of lower-CO₂ cements, accounting for a minimum 15% reduction; development and introduction of new technologies to the production process, targeting especially indirect emissions by modernising energy sources, accounting for a minimum 15% reduction; assumption of future technologies, accounting for a minimum 50% reduction.

Spain: 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.’

Russia: Italy-based Buzzi UniCem subsidiary SLK Cement has concluded an environmental agreement with the Sverdlovsk Oblast Ministry of Energy and Housing and Communal Services for the co-processing of solid municipal waste at its 1.0Mt/yr Sukholozhskcement plant. AMF Online News has reported that the transition, part of a nationwide government initiative called simply ‘Ecology,’ entails a modernisation of the kiln line, which the company says will be commissioned in 2023 or 2024. SLK Cement general director Andrei Immoreev said that alternative fuels use will not only increase production efficiency, but will also contribute to solving the environmental problems of the region.”

Vietnam: A Memorandum of Understanding (MoU) to build public private collaborations towards a circular economy for plastic waste management was signed in Hanoi on 19 February 2020. The agreement, the first of its kind in Vietnam, was signed by the Ministry of Natural Resources and Environment, Dow Chemical Company Vietnam, Siam Cement Group (SCG), and Unilever Vietnam International.

Deputy Minister of Natural Resources and Environment Vo Tuan Nhan said the average use of plastic per capita in Vietnam is not as high as that of developed countries in the world. However, with a population of nearly 100 million and an incomplete solid waste management infrastructure, plastic waste has been a big challenge for developing countries like Vietnam. It is likely that SCG will act as an off-taker of non-recyclable plastic residues, burning them as an alternative for fossil fuels in its cement kilns.

Cuba: State-owned Cementos Cienfuegos has started to burn waste tyres in order to save on imported petcoke costs. Cuba is suffering a coal shortage due to reinforced economic sanctions led by the US.

The plant is using 130-150 tyres per day as part of a project that, in its initial phase, makes it possible to replace 5% of its petcoke requirements. Plant manager Ernesto Gálvez, explained the plant eventually aims to burn 400 tyres per day.

Oman: 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.

South Korea: Asia Cement has awarded a contract to Germany’s Humboldt Wedag, a subsidiary of KHD Humboldt Wedag International, to supply and provide engineering for the modernisation of its third clinker production line at its Jecheon plant. The target of the upgrade project is to increase the alternative fuel substitution rate to above 85% of calciner fuel, as well as the reduction of NOx to satisfy local emission limits.

KHD’s scope includes the engineering and supply of mechanical equipment for the clinker production as well as electrical equipment for the overall modernisation of the production process. During the project, the existing preheater will be modernised with the installation of a new Pyroclon R calciner, as well as a Pyrorotor rotary combustion reactor for low-processed alternative fuel.

The overall project scope consists of: a Pyroclon R calciner with Pyrotop mixing chamber; a Pyrorotor alternative fuel combustion reactor; a Pyrobox coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones for calciner connection and an overall pressure drop reduction; bypass mixing chamber installation; and a new kiln inlet chamber with orifice.

The commissioning of the modernised production line is planned for the first quarter of 2021.
