The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company’s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area.   The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed. The model will then be adjusted to fit a case company, which in this case is Sandvik Materials Technology (SMT) on Sandvik.   The purpose is answered by detailed studies of the literature in the subject combined with interviews and observations on SMT. Through this the key factors have been identified and a model has been developed. The factors that were seen as most crucial were sorting, tied up capital, transport cost and handling cost. These factors have a strong connection between each other and it is important to strike a balance.   By the investigation carried out on SMT it is clear that sorting is the essential factor on the case company, and have the biggest impact on the effectiveness of the returned steel flow. Without functioning sorting there will be a large increase in the quality defect costs. Another factor that was considered important is the number of storage places, where a decrease in the storage places would reduce the tied up capital.
