Studying the Method of Upcycling of Landfills of Joan Valley Landscape (Garaf)

Nowadays, one of the urban problems is proper waste management with minimal damage to the environment. Landfills are one of the most common waste management solutions in the world. However, according to studies conducted by researchers, the useful life of these sites is between 25 and 30. In recent decades, the revitalization of these sites has attracted worldwide attention, and we are witnessing many successful projects around the world. Unfortunately, the landfill policy in Iran is still neglected. The purpose of this article is to learn from the experiences of projects carried out worldwide in order to use these experiences in the management of Iranian cities by selecting the landfill of the Xuan Valley (Garaf) as a case study and a successful project (selected 8 architectural competitions worldwide), This project has been reviewed and analyzed by reviewing the texts and interviewing the project design company. At the beginning, using the measures and strategies adopted in this project, according to the existing challenges of the site and high-level policies, the strengths and weaknesses of the project have been expertly analyzed, and finally, important factors in the project's approach to modeling have been explained. Similar projects have been discussed with regard to the current problems of Tehran in the development of landfills and the use of other cities in Iran.
