National Cement testing biomass use at Dire Dewa plant
20 April 2023Ethiopia: East Africa Holding (EAH) has set up a subsidiary, Pan Afric Energy, to pilot using the prosopis juliflora shrub as a biomass alternative fuel at its integrated Dire Dewa plant operated by its National Cement subsidiary. The US$50m project testing using the invasive species is backed for a number of different partners, including the local government and the European Union, according to the Capital newspaper. So far the initiative has reached a 5% thermal substitution rate at the Dire Dewa plant. The project is also considering using the shrub as an alternative fuel at a new cement plant being built at Lemi town, in the North Shoa zone of Amhara region. EAH has formed a joint-venture with China-based West China International Holding to build the new plant.
Irish government exempt from costs for 'unmeritorious' Limerick cement plant alternative fuels challenge
25 January 2023Ireland: A court has ruled that the Irish government need not pay legal costs for Environmental Trust Ireland president Michelle Hayes' challenge against the Environmental Protection Agency (EPA) in mid-2022. Hayes unsuccessfully sued the EPA for issuing Irish Cement with a licence to use alternative fuel (AF) at its Limerick cement plant in May 2021. The AF will comprise up to 90,000t/yr of waste tyres, biomass and/or mining by-products.
At the costs hearing, the court noted that Hayes had already caused the EPA to incur 'very significant' legal costs. The court said that Hayes 'sought to have the taxpayer pay even more.' It added that, as a solicitor at Hayes Solicitors Limerick, which represented her in her unsuccessful challenge, Hayes stood to effectively benefit from any recuperated costs. The court concluded "It would mean that legal practitioners like herself are paid by the taxpayer for bringing environmental litigation which is unmeritorious."
Cemex invests in WtEnergy
03 January 2023Spain: Mexico-based Cemex and its venture capital subsidiary Cemex Ventures have invested in Waste to Energy Advanced Solutions (WtEnergy), an energy startup company that has developed a process to transform solid waste into synthesis gas (Syngas) for industrial purposes.
WtEnergy converts biomass and non-recyclable waste into Syngas, which can be used in the short-term as a fossil fuel alternative or be upgraded in the medium- and long-term to gases such as biomethane or pure hydrogen. Cemex intends to incorporate this energy source into its clinker and cement manufacturing process, looking to further reduce the carbon footprint of its operations. Cemex aims to increase its fossil fuel substitution rate by 20% by 2030.
Gonzalo Galindo, the president of Cemex Ventures, said, “This investment aligns with our strategy to find innovative clean fuel and energy sources for the cement industry.” He added, “We have outlined an ambitious rollout strategy across multiple operations, starting with Spain and other European countries before expanding to other international markets.”
Germany: Zement- und Kalkwerke Otterbein plans to invest Euro10m in upgrades to its Otterbein cement plant to increase the sustainability of cement production there.
