Cities need robust carbon dioxide removal strategies to meet net-zero targets

Leading European cities race to reach net-zero emissions, but residual emissions are tied to easier-to-abate sectors and temporary, land-intensive carbon removal for compensation. To keep climate neutrality credible and fair, policy must tighten expectations on cutting emissions and set clear rules for carbon removal and credits. Recommendations for policy based on G. Ulpiani et al.

How cement plants can remove CO₂ from the atmosphere

Cement is one of the most in-demand building materials of our time. Every year, around four billion tonnes are produced. Cement production is energy-intensive, and greenhouse gases are emitted during the process – particularly during the thermal decomposition of limestone, the most important natural raw material for cement. In a new study, ETH researchers show

Wie Zementwerke der Atmosphäre CO₂ entziehen können

Zement gehört zu den am meisten nachgefragten Baumaterialien unserer Zeit. Weltweit werden jährlich rund vier Milliarden Tonnen davon produziert. Die Herstellung von Zement ist energieintensiv, und während des Verfahrens entstehen Treibhausgase – vor allem bei der thermischen Zersetzung von Kalkstein, dem wichtigsten natürlichen Rohstoff für Zement. ETH-Forschende zeigen in einer neuen Studie, dass diese Emissionen

China repurposing pharma mega-factories to make novel foods, GFI report reveals

China’s industrial fermentation ecosystem is among the largest and most developed in the world. Decades of investment in fermentation-based pharmaceuticals and vitamins have created a manufacturing sector with vast production capacity, experienced technical talent, established supply chains, and competitive operating costs. Historically, these companies have shown limited interest in food applications, since pharmaceuticals are often

Mitsubishi Electric develops CCU disaster-resilience evaluation with University of Tokyo

Mitsubishi Electric said on August 4 it had jointly developed with the University of Tokyo a technology that can quantitatively evaluate the economic value of carbon capture and utilization, or CCU, from both day-to-day carbon dioxide reduction and improved resilience during disasters. The Japanese industrial group said the method makes it possible to derive an

Pilot-scale production of leucine from CO2

Technology readiness The overall technology readiness level (TRL) of the leucine production process from CO2 with Methanothermobacter marburgensis as an archaeal cell factory is estimated to be at TRL 5. The overarching process is split into three parts, namely metabolic engineering of M. marburgensis, process development and scaling, as well as downstream processing. While markerless

Opinion: Europe’s climate-elephant in the room: What to do with left-over emissions when we get to net zero?

As the European Commission published its review of the EU Emissions Trading System (ETS), one of the first steps towards implementing the 2040 climate target to reduce emissions by 90 percent, Europe is moving towards the most challenging sources of emissions: “residual emissions”, which remain undefined in the policy architecture. Residual emissions are what is left

Green Lime: Reducing Carbon Emissions in the Construction Materials Industry

Lime, a key component in cement, can be used for both interior and exterior plastering. However, the production of this versatile building material generates significant emissions. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Hermsdorf, Thuringia, are developing a membrane reactor that enables climate-neutral lime production while also recovering new raw

Grüner Kalk: CO2-Emissionen in der Baustoffindustrie senken

Kalk lässt sich als Innen- und Außenputz nutzen und ist ein Hauptbestandteil von Zement. Die Herstellung des vielseitigen Baustoffs ist jedoch emissionsintensiv. Forschende des Fraunhofer-Instituts für Keramische Technologien und Systeme IKTS entwickeln in Hermsdorf (Thüringen) einen Membranreaktor, der eine klimaneutrale Kalkproduktion ermöglicht und gleichzeitig neue Rohstoffe schafft. Die Baustoffindustrie verursacht etwa ein Viertel der globalen

KIST team converts captured carbon dioxide directly into formic acid without purification

A process has been developed that converts carbon dioxide, a typical greenhouse gas, into formic acid, which is widely used in leather, pharmaceuticals and other applications. It directly converts captured carbon dioxide into formic acid using electricity, without separating, purifying or compressing the CO2. The Korea Institute of Science and Technology (KIST) announced on the
