UK: Cemex UK, part of Mexico-based Cemex, has renewed its 100% renewable electricity supply contract with France-based Engie until mid-2024. The supply will cover nearly 200 of its UK sites including its integrated cement plant at Rugby and its grinding plant at Tilbury.

Cemex’s Europe regional head of carbon, legacy landfill and special projects Martin Hills said, “Cemex has a dedicated Climate Action Plan for its global operations which outlines the company’s vision to advance towards a carbon-neutral economy and to address society’s increasing demands more efficiently. The use of renewable electricity at our sites plays an important part in this and we are pleased to have renewed our partnership with Engie for a further three years.

Nepal: Cement producers are unable to fully exploit increased demand following the coronavirus outbreak’s decline due to problems accessing reliable electricity. The Kathmandu Post newspaper has reported that outages and reduced power have stopped production for some companies and led to increased costs. Brij Cement has reportedly resorted to diesel generators, increasing cement’s production costs by US$0.26/bag.

Brij Cement’s general manager Ravi Kumar said, "It is difficult to run a factory without regular electricity supply. And even if there is power supply, it keeps fluctuating, causing problems."

Chile: Melón has signed an electricity supply contract with Enel Generación. The contract covers the supply for its La Calera, Puerto Montt and Ventanas cement plants, and its San Bernardo aggregates quarry, until 2043, according to the La Tercera newspaper. All energy supplied under the contract will come from renewable sources. There is also the possibility of expanding the scope of the contract.

General Manager Iván Marinado said, “Our commitment to the sustainability of our operations is permanent. We have state-of-the-art technologies, we work together with our carriers in programmes to reduce logistical impact and energy efficiency, and we have a solid co-processing strategy for the use of alternative fuels (AF) and raw materials. Today we are happy to take a new step and start the use of renewable energies, as a concrete and effective example of our concern to contribute to the environmental improvement of the localities where we operate.”

Mexico: Nearly 500 cement and concrete plants in the northern Mexican states of Chihuahua, Coahuila, Nuevo León and Sonora have partly or fully suspended production due to an on-going regional shortage of natural gas. The El Financiero newspaper reports that plants run by Grupo Cementos Chihuahua (GCC), Cemex, Holcim and Cruz Azul operate in this region.

GCC said that a lack of electricity and natural gas had affected production at three of its plants in Chihuahua, Samalayuca and Juárez. Mexican Association of the Ready-mix Concrete Industry (AMIC) president Ana Laura Burciaga said that the situation has caused a 50% drop in the cement supply to concrete plants.

The cause of the shortage is reported to be the suspension of natural gas exports from Texas, US. Mexican steel and automotive manufacturers have also been affected.

Mexico: Cementos Moctezuma is installing a 10MW solar power plant at its San Luis Potosí cement plant. Forbes Mexico has reported the estimated cost of the project as US$10m. It will consist of between 32,000 and 33,000 panels.

The company said, "The energy generated will be used at the Cerritos de Cementos Moctezuma plant, in order to replace a percentage of the electricity purchased from the Federal Electricity Commission (CFE), which is produced with fossil fuels and emits greenhouse gases.” It added that it aims to generate economic savings in the medium term as well as following its sustainability policies.

Pakistan: The Ministry of Commerce has advised the government that a concessionary rate for cement companies for the supply of electricity would reduce costs and increase international competitiveness. The Business Recorder newspaper has reported that the ministry proposed the measure due to the industry’s ‘immense’ potential for exports. In the 2020 financial year, the country exported US$266m-worth of cement. The ministry said that the current government’s policies would cause this to ‘substantially’ increase.

Uzbekistan: TThe Ministry of Energy says that it has not shut off the electricity supply to various cement plants, as alleged within private messaging channels. It stated the example of the Okhangaran cement plant, which, during the alleged shutdown, was received a recorded 605,000kWh of power on 24 November 2020, up by 12% from its average supply of 540,000kWh/day.

The ministry said, “Anyone who disseminates any information to a specific audience needs to clearly understand their responsibility.”

Vietnam: Tan Thang Cement has commissioned a control system package supplied by Switzerland-based ABB for a new cement plant in Nghe An province. The order included an ABB Ability System 800xA DCS (Distributed Control System), which integrates control, electrical and communication systems, ABB Ability Knowledge Manager and ABB Ability Expert Optimizer products which are integrated with the DCS, and basic communication and electrical system infrastructure and equipment.

"This was a challenging project many years in development and we delivered the control system package within our customer's timeframe. We used remote support and provided all necessary training to ensure that the plant team could complete the commissioning accurately and safely," said Nguyen Hoang Giang, Division Manager for Process Industries, ABB Vietnam.

On the electrical side, ABB provided a 110kV air insulated substation, with a SCADA (Supervisory Control and Data Acquisition) system based on ABB Ability System 800xA for Power Control, as well as telecommunications, and high voltage primary and secondary equipment to support the electrical infrastructure. ABB also delivered power transformers, distribution transformers, a motor control centre, auxiliary control centre, emergency diesel generator, DC power supply, various field devices, and related commissioning services.

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.

Paraguay: The government has re-opened borders to imports of cement due to a national shortage. The Última Hora newspaper has reported that importers will be free to bring cement into the country without having first applied for a provisional import licence. The situation is the result of growth in demand after the coronavirus lockdown and the suspension of production at Yguazú Cementos due to ‘a problem with a transformer.’ The government has already issued Yguazú Cementos with a 15,000t/yr cement import licence due to this.
