Holcim US opens solar power plant at Hagerstown cement plant
09 October 2020US: LafargeHolcim subsidiary Holcim US has opened a 10MW solar power plant at its Hagerstown, Maryland cement plant in partnership with Greenbacker Renewable Energy Company. The producer says that the power plant will supply 25% of the cement plant’s energy needs, reducing its carbon dioxide (CO2) emissions by 12,400t/yr.
LafargeHolcim cement US operations chief executive officer (CEO) Jamie Gentoso said, “As solar technologies continue to improve, this abundant energy source stands out as both a sustainable and economical solution to follow through on our commitment to minimise emissions and reduce our carbon footprint. We already have access to large areas of land with a high concentration of sunlight, so utilising solar energy is an easy decision. As we strive toward becoming a net-zero company, clean energy is a key part of our strategy. We hope to install enough renewable energy to power all of our plants and give back to the surrounding communities by 2026; this new solar array is just the beginning for us.”
India: Sustainable roofing specialist Visaka Industries has acquired a 20-year patent for production of ATUM, a roofing system consisting of cement boards with integrated solar panels. The company says that the product, which has been in development since 2016, is both insulative and capable of generating up to 28W/m2 of power.
India: Aditya Birla subsidiary UltraTech Cement said that it will spend US$200m in capital expenditure (CAPEX) during the 2021 financial year, which ends on 31 March 2021. The plans consist of a capacity expansion to 118Mt/yr from 115Mt/yr, including the completion of the 4.0Mt/yr Bara grinding plant in Uttar Pradesh and 1.2Mt/yr-worth of brownfield projects in Bihar and West Bengal. Solar and wind power capacity will increase to 350MW from 95MW, while waste heat recovery (WHR) capacity will increase to 185MW from 118MW.
Chair Kumar Birla said, “While 2021 will be a challenging year, Birla remains confident that the economy will revert to the 6 - 8% growth trajectory in 2022.”
Zimbabwe: PPC Zimbabwe has announced that it has entered into a preliminary agreement with a Zimbabwe-based energy investor “with technical partners in South Africa” that will build and operate the company’s planned 32MW solar power plant in Matabeleland South. 16MW will power PPC Zimbabwe’s cement production and the rest will be fed in the national electricity grid, according to the Herald newspaper. The unit will be located adjacent to PPC Zimbabwe’s 0.5Mt/yr integrated Colleen Bawn plant.
News roundup
18 March 2020With events moving fast in Europe with regard to the on-going health crisis, here are a few threads to consider from the cement industry news this week.
Firstly, there have been two solar power stories over the last week in North America. Grupo Argos said that it had installed a 10.6MW solar power plant at Cementos Argos’ Piedras Azules cement plant in Comayagua. Then US-based Alamo Cement Company was reported to have signed a contract with Renergetica to build a solar power plant at its integrated plant in San Antonio, Texas. Global Cement has looked at this topic on and off over the years from the steady addition of photovoltaic (PV) solar plants around the world to supply electricity to cement plants to more ambitious plans such as research into using concentrated solar power to start powering creating clinker directly. These two latest PV stories follow projects in El Salvador and Cyprus so far this year. We’re not going to comment now on the overall progress the cement industry is making towards moving away from fossil fuels but the general trend is encouraging.
Next, there are on-going investments and upgrade projects being announced. Germany’s KHD revealed on 17 March 2020 that is building a new raw mill and pyroprocessing line for an ACC plant in India. FCT combustion recently announced that it has won a deal to supply Titan Cement in the US with an upgrade to a kiln line to natural gas. Buzzi Unicem’s SLK Cement in Russia has agreed to co-process solid municipal waste at its Sukholozhskcement plant. South Africa’s PPC has invested in a pneumatic offloading facility and a silo for its George Depot cement terminal in the Western Cape. These will have likely been agreed before the global coronavirus outbreak but they are reminders that some level of capital expenditure by cement companies is happening.
In China the Ministry of Industry and Information Technology (MIIT) said this week that the domestic cement sector’s net profit grew by 20% year-on-year to US$26.6bn in 2019. With this in mind the first quarter results for 2020 from cement producers in China will make essential reading for producers from elsewhere around the world wondering what to expect. However, a recent interview with the president of Huaxin Cement, a company based in Hubei province at the epicentre of the outbreak, revealed that despite the short term economic disruption from the quarantine the company was expecting a rapid economic rebound after April 2020 provided that there is a suitable government stewardship. He also mentioned the key role the company was playing in disposing of clinical waste. As such it was hoping for tax breaks to support continuing incineration and the advancement of co-processing in general.
Finally, also on the health crisis, many cement industry events have been cancelled or postponed as work practices change including those organised by Global Cement. We’re taking our events online in the short term as virtual conferences with opportunities for information exchange and networking. We encourage as many of you as possible to register.
US: Italy-based Buzzi-Unicem subsidiary Alamo Cement Company has signed a contract with Italy-based renewable power supply expert Renergetica for the construction of a solar power plant at its 1.1Mt/yr integrated Plant 1604 cement plant in San Antonio, Texas. Renewables Now News has reported that the plant will have a capacity of 10MW.
Argos installs solar power plant at Comayagua plant
13 March 2020Honduras: Colombia-based Grupo Argos energy subsidiary Celsia has announced that it has installed a 10.6MW solar power plant at Cementos Argos’ 1.0Mt/yr integrated Piedras Azules cement plant in Comayagua. Renewables Now News has reported that the 32,000-panel plant on the roof of the Piedras Azules plant will generate 20% of its operating power needs. Celsia says that the solar plant, its first in Honduras, will reduce Cementos Argos’ annual CO2 emissions by 10,000t/yr.
El Salvador: Switzerland-based LafargeHolcim subsidiary Holcim El Salvador has announced a planned investment of US$7.5m to establish six concrete plants in 2020, which will bring its total to 18 plants. Esmerk Latin American News has reported that the investment also covers ‘new trucks and other machinery.’ Holcim El Salvador also announced its intention ‘in the long term’ to resume operations at its 1.6Mt/yr Maya cement plant, mothballed in 2008, at an estimated cost of US$20m. It is currently investigating the possibility of installing a US$5m solar power plant at its 1.7Mt/yr El Ronco cement plant.
In 2019 Holcim El Salvador produced 1.2Mt of cement and 710,000m3 of concrete.
Vassiliko Cement launches solar plant
13 February 2020Cyprus: Vassiliko Cement has launched an 8MWh photovoltaic solar plant. It is located in a former quarry in the Amalas area, approximately 8km from its cement plant. The unit is expected to supply around 10% of the cement plant’s electricity requirements. The project had an investment of around Euro6.5m. The lead contractor on the project was Sunel.
Grupo Cementos de Chihuahua secures solar power contract
18 December 2019Mexico: Grupo Cementos de Chihuahua (GCC) has signed a 15-year power supply agreement with a Mexico-based solar energy provider. The Awareness Times newspaper has reported that the contract covers the supply of solar power to GCC’s 0.2Mt/yr Juarez cement plant in Chihuahua, as well as its head office and ready mix and aggregates operations, constituting roughly 20% of its electricity consumption. The agreement, which enters force on 1 January 2021, will save GCC US$2.5m/yr and cut 0.3Mt of CO2 emissions throughout its duration.
