Waste collection and recycling processes represents a strategic activity in supporting the circular transition. The present research deals with disposable diapers collection; indeed, in order to increase the recycling rates of such typologies of waste, during the very recent years, waste management companies initiated to collect those separately from other household waste streams with different typology of collections. Making use of a case study grounded on raw data from six municipalities within Lucca province (Italy), our research aims at assessing, using an Analytic Hierarchic Process (AHP), six possible scenarios for used disposable diapers collection. Results shows that the best scenario is represented by the one where disposable diapers are collected from users by a curbside door-to-door collection system on a weekly base. Results are discussed under a managerial perspective in order to support future decision-making processes in waste management companies.
