The project of comprehensive waste studies of the city and Dihuk district was implemented with the aim of optimizing waste management and reducing the environmental effects caused by improper waste disposal. This project included the investigation and analysis of the current situation of production, collection, transportation and disposal of urban and rural waste. In these studies, different types of waste, including household, industrial, agricultural and hazardous waste, were identified and categorized in order to determine the optimal solutions for managing each category. One of the most important parts of this project was the development of programs to reduce waste production, promote recycling and reuse of materials, and design modern waste collection and disposal systems. Also, the feasibility of establishing recycling and waste management facilities, such as compost plants and waste separation systems, was investigated. The implementation of this project has helped to improve the environment of the region, reduce pollution and preserve natural resources, and has provided a comprehensive road map for sustainable waste management in the city and district of Dihok.
