Abstract: Sustainability means process of change in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations. Sulaimani city is located in Kurdistan Region of Iraq, the new master plan of Sulaimani proposed to lead for sustainability and for more green areas in the city. The biggest reason that face the new master plan of Sulaimani is Tanjero as multi land used area and Tanjaro River. Tanjero is located at the South West of Sulaimani city also it is considered as part of 2020's city (new smart city) to achieve the principles of sustainability and its pillars. The choice of Tanjaro was due to its location where heavy environmental pollution exists which caused by the surrounding areas, as water pollution occurred as a result of shortage in the water filtration system. Pollution of Tanjero River caused an environmental pollutions and health problems for Tanjero and the surrounded areas. Tanjero River is considered as the main problem for implementing of Sulaimani city master plan. In order to solve this problem, the researchers are applied some sustainable techniques that lead to environmental protection and cleaning the damaged areas of Tanjero, good economic base for the 2020 city and solving electrical production problem of Sulaimani city by using the Sulaimani waste as a resource behalf of using other limited resources, also to make the Sulaimani master plan much suitable to be implemented. Waste Management is applied as main sustainable techniques for solving existing problems. Concept and issues related to using sustainability methods and precisely biomass as a source of energy are discussed in this study. The daily Sulaimani wastes will use as a source to generate energy by using factory that change organic waste to clean energy. Note that, Sulaimani solid wastes is reached to 1200 tons, also the waste carried by Tanjero River reaches to 960 tons per day.
