France Accelerated Carbonation - Removals
Carbonated Materials
Industrial Processes
プロジェクト概要
Carbon8 has developed a project that captures CO₂ emitted from industrial or biogenic sources. The captured gas is injected into reactive materials, converting them into construction aggregates that can be used in concrete.
For this specific project activity, which is located in France at a cement plant, Carbon8 is treating a byproduct from the cement production process called Cement Bypass Dust (CBD) and mineralizing CO₂ with it. The resulting product is converted into construction aggregates.
Carbon8 has engineered a negative emissions technology, the CO2ntainer, that carbonates industrial residues on site directly from an industrial flue stack. The resulting carbonated residues from this process can be reused as construction aggregates, which have desirable performance characteristics for use in concrete manufacturing, as fertilizer, and as green roofing substrates. This creates a circular value chain which carbonates waste and redeploys it for use in the construction industry.
Carbon8’s containerized technology has been in operation since 2020 at a major global cement producer in France and has undergone technical trials in additional markets, including the Netherlands and Canada. These early anchor customers have provided a basis from which Carbon8 has built a full pipeline of commercial opportunities across the globe.
Carbonation happens naturally but very slowly at the levels of CO₂ in the atmosphere. Carbon8 discovered that by engineering the conditions of exposure to CO₂, the carbonation reaction can be dramatically accelerated and allow for the development of an economically viable form of carbon capture, utilization, and storage. When carbonation occurs, the pH of the residue reduces from highly alkaline towards neutral.
