Abstract
The concrete and cement industry is responsible for 8% of global greenhouse gas emissions, calling for solutions to minimize this impact. Research shows, that Carbon Reinforced Concrete (CRC) may be a part of the solution, as its production has lower carbon emissions. It is also more resource friendly than Steel Reinforced Concrete, saving up to 80% of concrete. However, there is little research on the End-of-Life (EoL) environmental performance of CRC and the re-utilization of its resources. In the context of the research project CRC/TRR280, we evaluate the environmental performance of diverse recycling options for CRC with varying degrees of manufacturing readiness, as well as downcycling effects. We map EoL technology paths, including demolition, transport, Carbon Fiber recovery, recycled concrete applications and recycled Carbon Fiber applications. Second, we model these scenarios in an LCA, reporting Global Warming Potential (GWP), as well as assessing Manufacturing Readiness Levels (MRL) for all processes. This allows decision-makers to quickly identify current hotspots within the CRC recycling path to achieving carbon neutrality.
