The Corporation of the City of Panaji (CCP), despite being a front runner in implementing measures such as source segregation, door-to-door coverage, and material recovery from dry waste, is facing an enormous challenge in handling the biodegradable waste that is generated in the city, especially, waste from bulk generators. Objective: The objective of the paper focuses on mapping of bulk waste generators in the 12 different zones of the city of Panaji, using the Geographic Information System (GIS), so the City Corporation of Panaji could devise a route map with suitable planning for waste collection and transportation. Methods: A Geographical Information System based methodology, which includes digitization of the bulk waste generators and preparation of map layouts. Results: The zone-wise mapping of the bulk waste generators revealed that zone 2, 3, 7, and 8 was highly concentrated with the number of bulk waste generators. Conclusions: As demonstrated in this study, the studied GIS methodology can be used for identification of the source of waste generation and further help in optimizing for waste collection and transportation in a city.
