<p>Large quantity of relief supplies left in the disaster zones and emergency warehouses after a disaster causes critical waste in practice both economically and environmentally, which brings challenges to local authorities on how to deal with them properly. In this paper, we consider the recycling and remanufacturing of relief supplies prepared for a certain disaster as another source of relief supplies pre-positioning for the next disaster, which not only provides more relief supplies at a lower cost but also benefits the sustainable development of humanitarian logistics. We consider multiple disasters occurring within a certain period and aim to design a continuous and sustainable mechanism in preparation for potential disasters and utilize supplies in a more sustainable way. On the basis of this background, we study how recycling and remanufacturing influence the contract design and pre-positioning strategies and further consider the impact of rotation using Stackelberg model. Results show that except for extreme situations, both the overall cost and quantity of inventory supplies of the local authority are reduced via recycling and remanufacturing, and the local authorities may further benefit from rotation in certain situations. Our proposed prepositioning model can provide guidance to local authorities to improve resource circularity and enhance the sustainability of humanitarian management.</p>
