World: The Global Cement and Concrete Association (GCCA) has named its first six startups to receive backing under the inaugural Innovandi Open Challenge. The startups have partnered with GCCA members to help increase cement’s sustainability towards achieving net zero CO₂ concrete production by 2050. This will lead to the formation of six consortia to further test, develop and deploy their new technologies.

Carbon capture, utilisation and storage (CCUS) startups CarbonOrO, MOF Technologies and Saipem, all based in Europe, are among the participants. GCCA members are currently involved in dozens of pilot projects and aim to have 10 industrial-scale carbon capture plants installed by 2030. Other startups Carbon Upcycling Technologies and Fortera, from Canada and the US respectively, use captured CO₂ to produce low-carbon cement and cementitious materials, while UK-based Coomtech has developed a low-cost drying technology using turbulent air.

GCCA CEO Thomas Guillot said “It’s a proud moment to see the industry coming together to support such innovative start-ups on their journey. Our member companies were greatly impressed by their ambition to be a key part of the climate solution. The programme is another big step forward towards unlocking innovation to help us achieve our net zero goal.” He continued “As the need for resilient and sustainable communities to support a growing global population becomes more pressing , cement and concrete will be essential to providing the infrastructure and buildings that society needs. Achieving net zero concrete relies on a number of different groups playing their part, and as an industry we’re looking outwards as well as inwards, to see how start-ups like these can support our goals.”

Philippines: Holcim Philippines plans to invest US$4.18m in upgrades to its cement plants at La Union, Bacnotan, and Lugait, Misamis Oriental to improve business and sustainability performance.

The subsidiary of Switzerland-based Holcim held a ceremonial signing ceremony on 7 July 2021 to award the contract to Sinoma CBMIPH Construction to install a drying facility at the La Union plant. The project is intended to reduce the fuel consumption of the unit by reusing hot gases from operations to dry materials. The integrated plant was recently awarded an ISO 45001:2018 for Occupational Health and Safety Management System and recertified for ISO 9001:2015 (Quality Management System) and ISO 14001:2015 (Environmental Management System) by certification body TÜV Rheinland. Holcim Philippines has also contracted Sinoma CBMIPH to install a drying facility at its Lugait plant that will reduce moisture of raw materials to improve grinding operations. The La Union and Lugait projects are scheduled to be completed in the first quarter of 2022 and by the end of October 2021 respectively.

In January 2021, Holcim Philippines also started projects worth US$2.42m to raise the efficiency of converting qualified waste materials to alternative fuels of its cement plant in Bulacan, Norzagaray. These will enable its Geocycle subsidiary to support the Bulacan plant to increase its thermal substitution rate by using more post-consumer and municipal solid wastes as alternative fuels.

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.”

India: Shree Cement has ordered a TRT 5000/8.0 Triplex dryer from Germany’s Gebr. Pfeiffer. The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coal-power plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%. Artificial gypsum from the dryer will be used at other cement grinding plants in the country. The 50t/hr dryer will be installed at the end of 2018 and is expected to start commercial operation in mid-2019.

Gebr. Pfeiffer is also planning to partially calcine the gypsum in future installations of the dryer. The TRT Triplex dryer uses the uniflow principle, where both material and hot gasses flow in the same direction and pass through the dryer tubes from the centre outwards. Testing at the Gebr. Pfeiffer test station have yielded ‘positive’ results and further installations in other plants are being considered.

Ecuador: FCT Combustion has won an order to supply a clay dryer to Cemento Chimborazo. The order includes a complete raw material drying system. It consists of a 41.2t/hr Triplex drier and a fluidised bed combustion system for petcoke and alternative fuel firing. No value or commissioning date has been disclosed.

Honduras: France’s Fives has won a contract to supply a FCB Flash dryer for Cementos del Norte’s Bijao plant. The dryer will be installed on an existing ball mill that was supplied and installed by Fives FCB in 2001 for a production capacity of 90t/hr of pozzolanic cement. Since then the pozzolana content and moisture rate have increased. Once operational the grinding plant drying capacity will rise.
