Abstract :

Background and Objective: Landfills cause environmental degradation and pollution by producing greenhouse gases such as methane and carbon dioxide and producing leachate as well as contaminating surface and ground water. Recently, the ecological design approach as a framework for reducing environmental degradation by adapting municipal solid waste management to environmental processes is expanding widely. Ecological design strives to maximize comfort by minimizing damage to the environment and natural processes while enhancing people's quality of life. Ecological design strives to adapt to nature through the use of natural materials as well as environmental considerations.Method: In the present study, according to the definition of sustainable design and understanding its applications, in order to achieve the best, most complete and practical design for the site in question, existing maps of the area, including aerial maps, topography , GIS, vegetation, upstream maps, site development plans, survey of active sites in Landfill, survey of contaminant types, study of COD and BOD indices of the site have been studied, as well as review and identification of existing status           (Environmental, Physical, Climatic, Landscape, Land Use, Transportation, Biological) through observation, photography and interviewing strategic design of this area is provided with ecological-based approach by site staff and residents of neighboring neighborhoods in accordance with the principles and principles governing the design of industrial environments.Findings: The existing plan prevents contamination of groundwater levels and prevents contaminated surrounding urban areas and agricultural lands. Restoration of damaged parts of the landfill, reduction of the risk of contamination by animals and noise pollution and unpleasant odors and its release into the atmosphere. The landfill is one of the main sources of greenhouse gas emissions in the country through biogas production from landfill gas collection and reduction of fossil fuel use. By collecting and using Landfill gases as fuel and power generation, the rate of emissions to the atmosphere is reduced. Maximum use of biogas is due to the greater use of digesters.Discussion & Conclusion: Design criteria are mainly based on existing constraints and needs and make the designer's policy clearer and significantly help in locating applications. Applying these criteria will help to enhance opportunities and take advantage of existing opportunities and make the project less threatening. After developing the strategies, designing from different perspectives is done to finally select the best plan for implementation by reviewing the concepts and comparing them with each other and in accordance with international standards. At the end of the study, the three concepts are finally selected and after examining these three concepts together, the winning concept is selected for the execution phase. Landfill is an inevitable step in waste management. In today's growing population, landfill has become an integral part of communities, but landfills should not be used as a last resort, but rather as a mean to create new uses for it. Converting landfills to recreational uses while also providing a pleasant place to meet the recreational and sporting needs of the area's inhabitants. Human landfill contaminates the area and destroys many animals and causes major disturbance in nature. Brings to enhance the quality of the landfills and with as the landfill site becomes more prone to disruption, it is necessary to look at the area as a demolished mosaic and take steps to repair it.
