Firstly, this study researches the efficiency of the recycling systems that is composed by two or three recycling technologies. Next, this study shows effect and impact that is made by the recycling systems composed of the recycling technologies and these locations. At the end, this study shows it is more efficient to create circulation in a narrower area, in the case of setting distance of transportation systems and area of recycling systems as the variable numbers
