Holcim has invested in CO2 mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO2 by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO2 removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to
Norway-based Capsol Technologies says that it has signed contracts for two new feasibility studies for carbon capture installations at ‘large cement plants’ in the EU. If successful, the plants will proceed to the installation of Capsol Technologies’ CapsolEoP carbon capture systems. Nordic Daily News has reported that the technology reduces the energy consumption of carbon
The French cement sector association, France Ciment, has called on the government to make ‘heavy investments’ in the industry amid its on-going transition to net zero CO2 cement production. It estimated the total cost of its transition, which will include carbon capture, at Euro3.5bn. The association said that producers currently benefit from the government’s partial price
Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO2, using solar heat. La Tribune de Genève Online News has reported
Cemex and industrial solar heat specialist Synhelion have achieved constant clinker production on an industrially viable scale using only solar heat. The partners say that this confirms the technology’s potential for industrial-scale implementation. Cemex CEO Fernando A González said “I am convinced we are getting closer to the technologies that will enable net-zero CO2 cement and
A team at Imperial College London has won a US$1.27m grant for its research into developing carbon negative cement from silica. The research won the Department for Energy Security and Net Zero (DESNZ)’s Carbon Capture, Usage & Storage (CCUS) Innovation 2.0 competition. The Imperial team sources its silica from natural olivine. It says that the
UNACEM Peru said that it reduced its CO2 emissions per tonne of cement by 2.7% year-on-year during 2022. Throughout the year, the company reduced its electricity consumption by 3.4%. It sourced 90% of its electricity from renewable sources and met 70% of its fuel needs with natural gas. UNACEM Peru is committed to reaching carbon neutral
Asia Cement has launched its 2050 decarbonisation strategy, entitled ‘Net-Zero Carbon Emissions By 2050 – Asia Cement Advanced Deployment.’ The strategy consists of multiple pillars, namely ‘alternative fuels,’ ‘reducing cement’s clinker factor,’ ‘increasing renewable energy reliance’ and ‘carbon capture.’ During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal
The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO2 cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO2 emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net
