This book is the fourth and last volume in the series of training manuals on developing integrated solid waste management (ISWM) plans. It aims to build the capacity of practitioners and policy makers for developing a comprehensive ISWM plan by utilizing the information collected earlier regarding waste characterization and quantification, assessment of current waste management system and gaps therein, and targets and issues of concern for ISWM. The manual provides a methodology for developing the ISWM Plan utilizing the information from Volume 1 and Volume 2 as baseline information and information from Volume 3 for contextualizing the Plan. The manual also provides guidelines for developing specific projects/schemes along with an implementation strategy.
