Companies Producing CO2-Absorbing Concrete
Four additional companies involved in the CO2-absorbing (or carbon negative) concrete industry include Lafargeholcim, Carbicrete, Heidelbergcement, and Centralconcrete.
- Lafargeholcim's prefabricated concrete solutions and services are designed to reduce the CO2 footprint.
- Lafargeholcim offers innovative thermal efficient concrete products, such as Thermedia, EcoTerm, or Thermicimo.
- Lafargeholcim uses its innovativeness, such as the Ultra High Performance Concrete (UHPC) Ductal, to develop efficient building systems that combine cement, aggregates, and concrete solutions with other insulating components to create energy-efficient construction elements.
- Some of Lafargeholcim's ready-mix concretes include Agilia self-placing concrete, Artevia decorative concrete, Chronolia high early strength concrete, Extensia high strength, low shrinkage concrete, Hydromedia permeable concrete, and Thermedia insultating concrete.
- With more than 25 percent, Lafargeholcim is the leading international cement companies with the highest reduction of carbon emissions per ton of cement since 1990.
- Lafargeholcim develops the best range of multi-purpose concrete products and solutions in the buildings and infrastructure construction industry.
- Carbicrete produces cement-free, carbon-negative concrete.
- In 2018, Carbicrete made through to the final rounds in the $20M NRG COSIA Carbon XPRIZE, a "global competition challenging teams to transform the way the world addresses CO2 emissions with breakthrough circular carbon technologies that convert carbon dioxide emissions from power plants into valuable products."
- Through a replacement technology, Carbicrete was the first company to develop a carbon-negative alternative to cement-based concrete.
- Carbicrete’s technology of producing concrete without using cement entails using steel slag as the primary binder and carbon dioxide as the activator in cement-free concrete.
- Carbicrete’s carbonation activation process enables the production of high-quality concrete using mineral waste and CO2.
- Heidelbergcement was the first cement producer to have Science-Based Targets initiative (SBTi)-verified CO2 reduction targets.
- Heidelbergcement develops cements and concretes with improved carbon footprint.
- Heidelbergcement's processes reduce CO2 emissions by reducing the proportion of clinker.
- Heidelbergcement aims to reduce its specific net CO2 emissions per tonne of cement by 30 per cent by 2030. In 2019, Heidelbergcement reduced its specific net CO2 emissions to 589.8kg CO2/tonne of cement.
- In the last decade, Heidelbergcement has invested more than €1 billion in energy efficiency and emission reduction measures.
- According to Dr. Dominik von Achten, the Chairman of the Managing Board, Heidelbergcement is "investing in improving the energy efficiency of our production facilities, using alternative raw materials and fuels, and replacing CO2-intensive clinker in our cement with raw and waste materials that have a significantly-lower carbon footprint."
- Heidelbergcement uses carbonisation to incorporate CO2 as raw materials in their products.
- Centralconcrete is the leader in delivering low-CO2 concrete to the San Francisco Bay Area.
- Centralconcrete designs and delivers higher-performing concrete and lowers the carbon footprint with its low carbon mixes.
- Centralconcrete has invested in CarbonCure, a technology that recycles CO2 to reduce the carbon footprint in a bid to design and deliver higher-performing concrete.
- Central Concrete is a founding member of the Carbon Leadership Forum (CLF), a group dedicated to devising standards that limit the carbon footprint of building products.
- Centralconcrete houses U.S. Concrete’s National Research Laboratory, which has, through its research, significantly advanced the performance of concrete.
