Build Back Better for war-torn Ukraine: Dual strategies for integrating circularity in post-disaster recovery

The circular economy has long been regarded as a fundamental strategy for achieving sustainable development. Most recently, it has also been acknowledged as an effective approach to crisis response. This study contributes to this nascent literature by introducing a dual hierarchy of 6Rs strategies as an inspiring framework for circular post-disaster recovery and reconstruction, supporting the Build Back Better principle through circular initiatives. The key distinction between the proposed hierarchy and the traditional 6Rs framework lies in the two-vector operationalization of each strategy, addressing both past and future considerations. Also, this article examines the case of war-torn Ukraine as one of the most severe man-made disasters. The study explores Ukraine's potential for circular recovery within the framework of European Union policies in the construction sector.
