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.

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.’

Germany: Beumer Group has developed a screw weigh feeder with automatic calibration. The company says it is especially well suited to exact and controlled feeding of inhomogeneous bulk materials of densities between 0.08t/m³ and 0.80t/m³ and extremely high moisture content such as alternative fuels. Its capacity is 30t/hr and its weighing tolerance is between 1% and 2%. It is completely covered to prevent dust and other environmental stresses.

Spain: Pedro Carranza, the CEO of Cementos Portland Valderrivas (CPV), has sought to reassure his company with regards to the future of the Alcalá de Guadaíara plant in Andalusia following a dispute with local authorities.

“The future of the Alcalá de Guadaíra cement plant is assured,” he said. “It is an efficient, low-cost and very well located plant in a very attractive economic environment where construction growth is above the national average. The Alcalá plant is here to stay.” Carranza added that only ‘distortion of international markets’ could compromise the plant’s future. He called for a surge in public infrastructure investment as soon as possible.

The plant has been involved in a long-running dispute with local authorities regarding co-processing of alternative fuels. A project is now underway. The plant is also exploring long-term renewable energy purchase contracts and the installation of solar panels on its site.

India: The excise department in the Indian state of Kerala has come to an agreement with Malabar Cement in which Malabar will burn seized contraband cigarettes and other tobacco products in its cement kilns. The company’s plant at Walayar is expected to receive up to 2t of material per month, in exchange for bags of cement from Malabar.

Italy: The Italian cement industry decreased its overall CO2 emissions by 8.9% in 2018 compared to 2017, in part by replacing a higher proportion of fossil fuels with alternative fuels and biomass fuels. The proportion of alternative fuels used increased to 19.7% in 2018 compared to 17.3% in 2019, according to Federbeton. This translates to 387,000t of alternative fuels.

Germany: HeidelbergCement’s specific CO₂ net emissions per tonne of cementitious material fell by 1.4% year-on-year to 599kg CO2/t in 2018 from 608kg CO₂/t in 2017. Despite this its absolute gross CO₂ emissions increased by 3% to 76.7Mt from 74.2Mt as clinker, cement, aggregate and concrete sales volumes all grew in 2018. The group has published the data in its Sustainability Report for the 2018 financial year.

“Cutting our CO₂ emissions and handling natural resources considerately are priorities for all our business lines,” says Bernd Scheifele, chairman of the managing board of HeidelbergCement. "We focus primarily on the development of sustainable products and the implementation of concrete measures at plant level in order to achieve our sustainability goals.” The company has set itself the target of a 30% reduction in its specific net CO₂ emissions per tonne of cement by 2030, compared with 1990. HeidelbergCement says it intends to realise its vision of CO₂-neutral concrete by 2050 at the latest.

Other figures of note in the report include an alternative fuels substitution rate of 21.7% in 2018 compared in 20.8% in 2017. NO_x, SO_x and particulate matter emissions all fell. However, total water withdrawal rose by 8% to 65.4Mm³ from 60.4Mm³ although water consumption fell.

Austria: Data from the Austrian Cement Industry Association (VÖZ) shows that cement production rose by 7.4% year-on-year to 5.2Mt in 2018. The increase has been attributed to a construction boom. Sales of cement grew by 4.7% to Euro432m. Sales continue to increase at a similar rate in the first quarter of 2019 but this has slowed down in the second quarter.

The association has said that environmental investment more than doubled in 2018 to Euro45m. The local industry’s alternative fuels substitution rate was 82% and CO₂ emissions fell by 0.8% to 521kg/t of cement.

Spain: Pedro Carranza, the chief executive officer (CEO) of Grupo Cementos Portland Valderrivas, has been named as the president of Fundación Laboral Andaluza del Cemento y el Medio Ambiente (FLACEMA). He succeeds Francisco Zunzunegui, who has held the post since late 2017. FLACEMA promotes the co-procesing of waste by the Andalusian cement industry. It was set up in 2003 by the Association of Manufacturers of Cement of Andalusia (AFCA) and a group of major unions.

Philippines: Republic Cement and Nestlé Philippines have signed an agreement to co-process Nestlé’s post-consumer plastic waste in Republic Cement’s cement kilns. The deal was signed by Nestlé Philippines’ Chairman and CEO Kais Marzouki, its Corporate Affairs Head Attorney Ernesto Mascenon and Republic Cement’s Renato Sunico and Nabil Francis, CEO of Republic Cement Services. In April 2018, Nestlé globally announced a commitment that 100% of its packaging will be recyclable or reusable by 2025. The company's vision is that none of its waste ends up in landfill or as litter.

“Nestlé is aiming for plastic neutrality, essentially recovering plastics equal to what we produce,” said Kais Marzouki. “Aside from our current collection and recycling initiatives, we believe this effort will help us gather and co-process bigger volumes of post-consumer waste. We target to divert more post-consumer waste from landfills and the ocean. This partnership will contribute positively in helping clean up the Philippines.”

“We are happy to partner with Nestlé Philippines and to help address the pollution from residual plastics and sachets,” said Nabil Francis. “This is a win-win situation for us and the environment. Together, we can build a greener, stronger republic.”
