Swiss decarbonisation report claims high cost for industry to reach net zero
A collaborative decarbonisation report on the Swiss cement sector between ETH Zürich, Jura Cement , Vigier Holding , Holcim , cemsuisse, Swiss Federal Office of Energy and the Federal Office for the Environment has advised that net zero can be achieved by 2050 at a CO 2 abatement cost of CHF113/tCO 2 (US$115/tCO 2 ). This would lead to a mothballed annual decarbonisation cost of approxima...
Seawater the key to low-carbon cement
Researchers at the University of Columbia, New York, USA, have developed a cement that uses magnesium hydroxide harvested from seawater instead of magnesium oxide, potentially removing more carbon than it releases during its production. According to a report in Chemistry World, although reactive magnesium oxide cements as a low-carbon alternative have been explored over recent years, these cem...
Picton plant applies for alternative low-carbon fuel permit
Lehigh Cement plant in Picton is examining alternative low-carbon fuels as part of its operations at the facility on County Road 49, just north of Picton, Ontario, Canada.

Project to target CO2 emissions from refractories
A research project, funded by the European Union, could help lower CO 2 emissions in the refractory industry by up to 800,000tpa. The initiative is known as the ReSoURCE project and involves eight research partners, led by RHI Magnesita. “On average, 60 per cent of all spent refractories, generated by refractory-consuming industries, go to landfill, while only 30 per cent is recycled. With...
