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.”

Switzerland: LafargeHolcim reduced its net CO₂ emissions per tonne of cementitious material by 1% year-on-year to 576kg CO₂/t in 2018 from 582kg CO₂/t in 2017. It said that the improvement was achieved by reducing the clinker-to-cement ratio and consuming less energy per tonne of cement, mostly by using alternative fuels and improving the efficiency of the company’s processes. However, data from its Sustainability Report 2018 shows that both its overall gross and net emissions grew. Its net CO₂ emissions from cementitious material increased by 2.5% to 121Mt. At the same time its clinker production rose by 2.7% to 151Mt from 147Mt.

The group increased its treatment of waste-derived resources to 52Mt. its alternative raw material substitute rate grew to 11.2% from 10.7%. It established a new pre-processing facility in Madukkarai in India and upgraded its waste handling capacities in Mexico, Ecuador, Brazil, Argentina, the Czech Republic, Bulgaria, India, Canada, Spain and Germany. It also reduced its freshwater withdrawal for cement production and improved its lost time injury rates.

RHI Magnesita has taken the step this week of raising its prices globally by 5% for its products for its industrial and steel divisions. It has applied the increase to both its basic (magnesia and dolomite based) and non-basic products, varying in a range of 3% to 20%. It has blamed this on a global scarcity of raw materials caused mostly by Chinese environmental regulations on mining and processing. It goes on to attribute the issue to increased export taxes, more restrictive allocation of explosives and the nationalisation or controlled consolidation of mining operations in China. All of this has, “...structurally altered the production, pricing and dynamics for industrial minerals.”

Other major refractory producers, including Imerys and Vesuvius, reported similar mounting raw material costs in 2018. They also implemented price changes to maintain income and/or sales growth. As can partly be seen in Graph 1 some of the major refractory producers reported mixed fortunes in 2018 for their divisions that produce products for the cement industry.

RHI Magnesita noted that 2018 was a year of steady refractory market growth and relative stability for cement and lime from a global market perspective, with some significant variances on a regional basis. Imery’s Energy Solutions & Specialties division suffered due to flat markets. However, its High Resistance Materials division (not shown in Graph 1) benefited from the ongoing integration of Kerneos into the group. The group restructured its businesses at the end of 2018 creating a High Temperature Materials & Solution segment that brings together its various refractory concerns. Vesuvius' Steel Advanced Refractories division, which include monolithic products, reported particular growth in the Americas in 2018. Although it noted some market share loss in North Asia and in certain European countries, the latter due in price increases.

Refractories aren’t the only material or commodity used by the cement industry that has been distorted by Chinese domestic policy. Regulations on imports of waste streams including plastics started in 2017 leading to European and US suppliers struggling to find alternate markets. One implications of this appears to have been waste firms focusing on separating plastic into high and low calorific fractions to fight the downward price trends of a market glut. The outcomes are different but the sheer size and variety of China’s economy is increasingly affecting the cement industry in new and different ways.

RHI Magnesita’s travails in China and the debacle of waste imports bring to mind the quote by the 19th century Austrian diplomat Klemens von Metternic, ‘When Paris sneezes, Europe catches a cold.’ Metternic was referring to Napoleonic-era France and its aftermath. The modern version may have been used to reference the US but maybe it should be instead, ‘When China sneezes, the world catches a cold.’ Gesundheit.
