US$3.2m grant to support algae-grown cement06 July 2022, Published under Cement NewsA team of researchers led by the University of Colorado Boulder, USA, has received a US$3.2m grant from the US Department of Energy to support the development of algae-grown cement. The university’s Will Srubar, associate professor in civil, environmental and architectural engineering, developed a way to harvest cement material from calcifying algae that consume water-dissolved CO 2 to produce limestone by photosynthesis. Algae-grown cement is carbon neutral because the same amount of C... |
Holcim, thyssenkrupp and Berlin University participate in amine scrubbing project31 March 2022, Published under Cement Newsthyssenkrupp Uhde, Holcim and the Technische Universität Berlin have partnered up in a joint project to investigate the use of a novel amine scrubbing technology for carbon capture. The goal is to significantly reduce CO 2 emissions from existing cement plants and at the same time utilise the captured CO 2 for other applications. In concrete terms, this includes the development of new mass transfer process equipment that is more efficient and resilient to contaminations. The project is be... |
CO2 to biofuels at Argos20 September 2021, Published under Cement NewsTo address the urgency of the climate crisis, a wide range of CCUS technology pathways are being explored by the cement industry. One of these options is the use of microalgae to capture CO 2 and transform it into valuable products. Over the past 10 years, Argos has been researching and scaling up the use of microalgae. Recently, the company has been testing a group of technologies to capture CO 2 directly from the cement plant smokestack using photobioreactors (PBRs) and transform the res... |
Safi CO2 helps grow Omega Green algae27 August 2019, Published under Cement NewsOmega Green, the algae cultivator in Eemshaven, The Netherlands, has opened a 1ha production location in Safi, Morocco. The company will use the CO2 emitted by HeidelbergCement’s Safi works to grow algae. The cultivation firm also has plans to upgrade the facility to 4ha with, according to co-owner Bert Knol, long-term goals by the German cement producer to extend the area to 400ha. The algae absorb 80-100tpa of CO2 from the air, or equivalent to the electricity generation required to po... |
Carbon conversion projects03 September 2014, Published under Cement NewsInnovative carbon conversion and/or utilisation projects aim to reduce the CO2 in the atmosphere by converting it into useful products, rather than sequestering it. Although most commonly encountered in the area of biofuels, there are many other applications. Carbon conversion and utilisation is the area where the highest level of future activity is anticipated.
