Abstract: The goal of this paper is to present a new planning optimisation framework for the disassembly processes of an end-of-life (EOL) building, by explicitly taking into account, as an input, its bill of materials. When disassembling an EOL building, there is the option either to selectively deconstruct specific components and materials for reuse and recycling, respectively, while demolishing the remainder of the building, or to further continue the deconstruction process and postpone the demolition of the building for a later stage. In this context, we present a novel, integrated, decision-making model for the entire construction and demolition supply chain, starting from the optimisation of the on-site deconstruction and demolition decisions till the delivery of the collected components and materials to potential recyclers/customers and landfills. An application of the developed methodology is demonstrated via a specific case study, while the relative obtained managerial insights, regarding the behaviour of the optimal solution, are presented.
