Work on upgrading the plant, which supplies three-quarters of the cement used in Sweden, was due to complete in 2030. "Since at Slite we will capture all the CO2, we will also capture the CO2 from the biomass, which is not counted when you calculate the emissions from the industry," Brevik said. AU - Duan, Wenhui. Pumping carbon into depleted fossil fields is controversial since the oil and gas industry is promoting a technique called carbon capture, utilisation and storage (CCUS) to help it extract remaining fossil reserves via a process known as enhanced oil recovery. Announced last year, this vast demonstration project aims to sequester 1.5 million tonnes of carbon under the sea per year by 2024 as part of a drive to demonstrate "the potential of this decarbonisation approach to Europe and the world". CEMEX, S.A.B. In fact, cement's annual carbon footprint would need to be reduced by almost 1/5th in the next eight years to achieve this. Material scientist Wil Srubar was visiting coral reefs in the area and drew inspiration from the way the structures are naturally formed by calcium carbonate, a key component of limestone. It could eliminate the 2 gigatons of carbon dioxide annually pumped into the atmosphere through traditional cement production. Portland Cement Association members are marking the first year of their Roadmap to Carbon Neutrality by 2050 by highlighting key deliverables for public and private construction market stakeholders. When the proposed upgrade is complete in 2030, the company claims it will capture and store all emissions from the Slite plant, totalling up to 1.8 million tonnes of CO2 per year.

The plant is currently the second-largest source of greenhouse gas emissions in Sweden, responsible for three per cent of all its CO2 emissions. Another startup, Solidia, says that its system can cut the carbon footprint of concrete by as much as 70%. A new initiative, Concrete Action for Climate, aims to bring the sector's stakeholders together to drive this transformation. Limestone is a key ingredient in cement, but adding it to the mix is incredibly energy intensive. I'm pretty sure that most of the environmental cost of turning limestone into cement is the heating of the CaCO3 to turn it into CaO, releasing CO2. Related story Construction industry "doesn't know where it stands when it comes to carbon emissions". Cement giant HeidelbergCement has announced plans to eliminate carbon emissions from a plant in Sweden in a bid to decarbonise one of the world's most polluting industries. Playing an indispensable role in global construction, cement contributes around seven percent of annual greenhouse gas emissions owing to its carbon-intensive production process. These tiny creatures naturally sequester and store carbon dioxide through photosynthesis, using sunlight and seawater to turn it into calcium carbonate at a faster rate than coral reefs. The Slite project follows another carbon-reduction project at another HeidelbergCement plant at Brevik in Norway, which will act as a pilot for the Swedish plant. Americas cement manufacturers have committed to the goal of reaching carbon neutrality throughout the cement-concrete-construction value chain by 2050. That is why in September 2020, 40 of the world's leading cement and concrete producers, represented by the GCCA, announced a global climate ambition: to produce carbon neutral concrete by 2050, in line with global climate targets. It's responsible for about 8% of . The scientists call it a net carbon-neutral way to make Portland cement, as the carbon dioxide released into the atmosphere equals what the microalgae already captured. The Portland Cement Association (PCA), also came forward with its plans to develop a roadmap by the end of next year (2021) "to facilitate its member companies achieving carbon neutrality across . Related story Architects should give up concrete say experts at Architecture of Emergency climate summit. Usually I would say "Nobody knows the answer", but clearly Nobody is asking something that anyone with a computer could easily know. The concrete industry is working to reduce its carbon footprint, but despite the amount of work already accomplished, there is still much to do. Using microalgae to make a key ingredient could drastically cut that carbon footprint.

UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. Brevik added that the project has the potential to become carbon negative since the factory will derive part of its energy from burning biomass since this contains carbon that has been drawn from the atmosphere by plants via photosynthesis. Now, a CU Boulder-led research team has figured out a way to make cement production carbon neutraland even carbon negativeby pulling carbon dioxide out of the air with the help of microalgae. The World Economic Forum is an independent international organization committed to improving the state of the world by engaging business, political, academic and other leaders of society to shape global, regional and industry agendas. Once captured, the carbon dioxide will be buried under the North Sea in cavities created by the extraction of fossil fuels. Earth Is Running Out of Sand, Which Is Concerning, Fusion Reactor Must Run 8 Times Hotter Than ITER, The Worlds Whitest Paint Could Change Aviation. Srubar says these "look, feel and behave exactly like concrete," but the cement used to create it is net carbon neutral or even carbon negative, in that the associated carbon dioxide emissions are less than what is captured by the microalgae. But the rate (faster than coral reefs) doesn't bode well as a replacement source. Released in mid-October 2021, the Roadmap outlines strategies in a value chainClinker, Cement, Concrete, Construction, Carbonationthrough . Students working on carbon neutral cement using biogenic limestone at the University of Colorado Boulder. Interesting way to copy nature. Perhaps most promisingly, the biogenic limestone is described as "plug and play" with current cement production processes, and could theoretically be implemented as quickly as overnight.
