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.

Studies to evaluate the potential of aquifer pollution caused by leachate infiltrating the Iranshahr landfill are carried out in order to identify and analyze the environmental effects caused by the leachate produced in this landfill. Leachates, as hazardous effluents resulting from the decomposition of waste, can contain toxic substances and microbial contaminants, which pose a serious threat to the water resources of the region if they penetrate into aquifers. In this study, using field and laboratory methods, sampling of underground water and leachate is done in order to investigate the concentration of polluting substances and the potential of contamination of aquifers. The results of this assessment not only help to determine the current state of aquifer pollution, but also can be the basis for decision-making to improve waste management and implement appropriate protective measures in Iranshahr landfill. The ultimate goal of these studies is to maintain the quality of water resources and the health of the region's ecosystem.

The project of reviewing waste management studies in Takab city is carried out with the aim of improving the existing systems and increasing the efficiency in the management and disposal of urban and industrial waste. This project includes analysis of the current situation, identification of problems and weaknesses of waste management systems, and assessment of environmental effects caused by improper waste management. In this process, a comprehensive review of the waste produced in the city, including all types of household, industrial, medical, and agricultural waste, is done. The main goal of this revision is to upgrade the management infrastructure and update the methods and technologies of waste collection, separation, recycling and disposal. Also, in this project, attention is paid to educating and informing citizens about reducing waste generation and the importance of separation at the source. The results of these studies will lead to the development of practical and sustainable solutions for waste management, minimizing environmental damage and improving the quality of life in Takab city.

Arian Shahr waste management comprehensive plan studies project is carried out in order to design and implement a comprehensive and sustainable system for urban, rural and industrial waste management. In these studies, a detailed assessment of the state of production, collection, transportation, processing and disposal of all types of wastes in this region, including household, agricultural, industrial and medical wastes is done. The purpose of these evaluations is to identify challenges and weaknesses in the current system and provide optimal solutions to improve its performance. In the framework of this plan, strategies are proposed to reduce waste generation at source, improve collection and separation processes, increase recycling capacity, and optimize final waste disposal methods. Also, these studies include the design of necessary infrastructure, including recycling sites, sanitary landfills, and separation centers. Educating and informing citizens and businesses about reducing waste production and separation from the source is another goal of this plan. The successful implementation of this comprehensive plan can lead to the improvement of environmental quality, reduction of pollution and optimal use of resources in Arian Shahr.

In order to evaluate the environmental consequences of constructing and operating the Mirjaveh landfill, Environmental Impact Assessment (EIA) studies for this project are currently underway. These studies aim to identify, analyze, and manage the potential impacts of the project on the environment, natural resources, and public health. With the support of a specialized team and a scientific approach, the assessment process covers site selection, technical design, waste disposal methods, and pollutant control. Additionally, strategies for minimizing negative impacts and enhancing environmental sustainability indicators are carefully considered within these studies. The outcomes of the assessment will play a vital role in guiding executive decisions and shaping effective management plans for the sustainable development of the region.

The design studies of the Mirjaveh landfill cell are being conducted with the aim of establishing an optimized, safe, and environmentally compliant waste disposal system. These studies include a thorough assessment of the geological, hydrological, and structural parameters of the area, with a focus on designing drainage liners, leachate collection systems, and landfill gas management. Special attention is given to preventing soil and groundwater contamination, as well as enhancing efficiency in waste management. These studies provide a solid scientific and technical foundation for the successful and sustainable implementation of the waste disposal project in Mirjaveh. The results of the design studies ensure compliance with environmental and technical regulations and play a vital role in safeguarding public health and protecting the regional environment.
