Austria: Loesche subsidiary A TEC has won a contract for the supply and installation of a Flash Dryer for alternative fuels (AFs) in the kiln line of Lafarge Zementwerke's 1.1Mt/yr Mannersdorf cement plant in Lower Austria. The supplier said that it will complete the project in early 2021.

The company said, “Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying the lifting effect of the gas can separate 3D impurities which contributes in a further increase of the fuel quality.”

South Korea: SungShin Cement has placed an order with Denmark-based FLSmidth for the supply of two HotPlate combustion devices for installation in lines three and six of its SungShin cement plant. The plant is in the transition from coal fuel to the possibility of 100% alternative fuel (AF) use in the two lines, which it plans to commission in mid and late 2021 respectively.

Team manager of production technology Cho K-R said, “With its degree of flexibility, the HotDisc allows us to substitute coal with a wide range of AFs – refuse-derived fuel (RDF) in our case. As we turn waste into energy, the HotDisc lowers our operating costs without compromising energy efficiency.”

FLSmidth previously delivered two HotDiscs to South Korea, to SsangYong’s Donghae and Yeongwool cement plants.

US: Bulk Handling Systems (BHS) has appointed Thomas Brooks as its chief technology officer (CTO). He previously worked as BHS’ Director of Technology and Product Development. Brooks was recently named a Waste360 40 Under 40 award winner. He has served in management and new product development roles in the aerospace, biomedical, industrial and automotive industries, among others. He holds a Bachelor’s Degree from Tennessee Tech University in Mechanical Engineering with a focus on controls and fluid dynamics.

Zimbabwe: The Environmental Management Agency (EMA) has ordered Lafarge Cement Zimbabwe to stop operations at its integrated Harare plant due to abnormal dust emissions. As part of the order the plant has been requested to notify local stakeholders and the community of any new developments or incident that may affect them, according to the NewsDay newspaper. It will also be required to report daily dust emissions readings to the EMA every two weeks.

The cement producer said it experienced an unexpected surge in dust emissions during a trial of using saw dust as an alternative fuel at the plant between July 30 and 1 August 2020. It added that immediate action was taken to control and contain the emissions and the incident was reported to EMA in line with regulatory requirements.

Mexico: Cemex says that the ongoing coronavirus pandemic will not delay its ‘Climate Action Strategy’ that was previously announced in February 2020. The building materials producer has developed a CO₂ reduction roadmap to help guide it towards a towards a targeted 35% reduction in net specific CO₂ emissions between 1990 and 2030.

The roadmap consists of: reduction of CO₂ emissions of clinker through “the production of novel clinkers with lower heat consumption”; use of “alternative decarbonated raw materials”; increased alternative fuel substitution; and increased substitution of clinker with “alternative cementitious materials, using admixtures to enhance strength, and adopting new grinding technologies to improve performance”; in addition to the increased use of renewable energy.

Cemex chief executive officer (CEO) Fernando Gonzalez said, “Climate change is one of the biggest challenges of our time, and we believe that we can continue to address it as a fundamental component of our efforts to recover from the Covid-19 pandemic.”

Hungary: Italy-based Entsorga has completed the installation of an automated alternative fuel (AF) line at a Hungarian cement plant.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.”

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.
