Limited financial resources and lack of data availability about the amount and composition of the solid waste are posing difficulties to regulatory bodies towards proper planning of solid waste management systems in big cities. Also, solid waste generation and characterization are the essential parameters that affect the environmental sustainability. The aim of this study is to document the information on waste quantity being produced and its composition in Gujranwala city of the Pakistan. Results of this study can help the government to develop a sound waste management system for such expanding cities in the country.
