This report presents three case studies in the context of centralised large-scale composting facilities in Sri Lanka in order to reveal the factors and approaches that led to positive results under different type of operational modality, i.e., 1) single municipal operation, 2) provincial operation, and 3) joint consortium operation (operated by two municipalities). This report is expected to enhance the capacity of local authorities in Sri Lanka and other countries, and also raise the level of knowledge on composting as well as planning and decision-making skills for successful implementation of composting facilities.
