There is no doubt that the iron and steel sector plays an important role in the determination of the
development level for countries. Especially the production and export values of this sector has the key role
of progress for countries. According to year of 2016 data, the annual production of iron and steel in the
world is 1.6 billion tonnes. On the other hand, Turkey is a remarkable spot in the iron and steel industry in
the world with an output of 33 million tons.Raising profit margins by lowering production costs has become
the most important issue all over the world, given the progress of the industry and the decline in available
resources. For this reason, waste management will be one of the leading factors for both reducing
manufacturing costs and bringing other new profit items. In addition, the developing environmental
consciousness has brought new concepts and trends in waste management. In this context, "zero waste" is
taken seriously in many countries and many commercial or non-commercial institutions. Especially in
Europe, it is predicted that these countries and institutions will switch to zero-waste production technologies
after a certain period of time.According to the year 2016, when iron and steel sector is evaluated in terms of
waste production, it will be seen that the slag production is 0,375 tons in the integrated system and 0,075
tons in the electric arc furnaces. Attempts to restore these wastes to the economy must be made in accordance
with the waste hierarchy. This is also important in terms of sustainable development. Reducing slag
production, investigation to utilization in different application should be analysed considering to scope of
zero waste.This study is focused on especially the EAF slags. First of all, the ways of recovery metal and
then the utilization of these slags in alternative applications were investigated.
