Abstract
This paper offers guidance on modelling reuse and recycling in the life cycle assessment of constructional steel. Reusing constructional steel can significantly reduce greenhouse gas emissions, conserve natural resources, and minimise the environmental impact of construction works. A material that cannot be reused is typically recovered and recycled, resulting in only a minimal amount of untreated end-of-life waste. Steel can be repeatedly recycled but reuse can only
be performed a limited number of times. This creates challenges in interpreting
EN 15804 for simultaneous closed-loop recycling and open-loop reuse. The recently published methodology by World Steel Association addresses this issue but is not harmonised with the European standards. Our study shows how to convert World Steel Association's lifecycle models to EN 15804 and back. It demonstrates that if the open-loop reuse cycle is embedded in the closed-loop
recycling, the whole system can be treated as closed-loop and simplified.
