Description du projet
Une technologie innovante pour traiter les déchets de construction
Le captage et l’utilisation du carbone (CCU) est un processus qui permet de capter le dioxyde de carbone (CO2) et de le convertir en substances ou produits de plus grande valeur. Dans ce contexte, le projet Carbon8, financé par l’UE, a mis au point la technologie de carbonatation accélérée (ACT), une version contrôlée et accélérée du processus de carbonatation naturel. Cette technologie apporte une solution d’économie circulaire aux déchets de construction industriels et aux émissions de CO2. À défaut, les déchets de l’industrie du bâtiment requièrent un prétraitement coûteux avant d’être transportés vers les décharges. L’ACT a déjà été déployé avec succès, sous licence par une société de gestion des déchets, à grande échelle. Le projet entend identifier les marchés et les produits finaux appropriés pour une version à échelle réduite de l’ACT.
Objectif
Carbon8 has developed Accelerated Carbonation Technology, ACT, a controlled, accelerated version of the naturally occurring carbonation process. It can be described as a CO2 capture and utilisation, or ‘CCU’, technology which captures CO2 to create a valuable, safe, carbon neutral or negative end-product which can be used as an aggregate by the construction industry.
The technology is applicable to hazardous waste from industries including cement, steel and Energy from Waste. These wastes otherwise represent a problem for the waste producer and typically require pre-treatment before transportation to landfill – at a cost of up to 150 Euros per tonne.
Carbon8’s technology has already been successfully deployed, under license by a waste management company, at large scale. This Phase 1 Project focuses on the identification of markets and suitable end-products for a small-scale version of the ACT technology - identified as more suitable to customer needs. The compact, containerized processing plant can be integrated into existing industrial processes, utilising CO2 contained in flue gas to treat the industrial waste. It represents a circular economy solution to both industrial waste and CO2 emissions.
Carbon8 estimates that around 20% of the EU’s 143 million tonnes of reactive waste might be available. These waste streams would have the potential to capture 3.5 Mt of CO2 /year. There is interest from major cement producers: Heidelberg, Lafarge, CRH, and Cemex and from EfW operators, particularly in northern Europe where disposal options are limited and costs highest.
By deploying smaller scale units with single waste streams, there is scope to fine tune the end product, an aggregate for the construction industry, with potential to ‘reverse-engineer’ a premium aggregate which can command a higher market value and further enhance the economic rationale.
