The construction industry is the largest contributor of waste in the EU, and research shows that a high sorting rate does not automatically entail a high recycling rate. The purpose of this study is, through a multiple case study, to provide better understanding of the waste flows and the prerequisites on the logistical operations within new build construction projects, considering the variation over time (construction phases). Waste data from five projects were analyzed. Results show that amount and mix of waste varieties vary considerably during a project, which has to be effectively managed by the waste logistics system.
