New study shows life cycle of stainless steels

Conducted by Barbara Reck, senior research scientist at Yale University, the 2015 study ‘Comprehensive Multilevel Cycle of Stainless Steel in 2015’ concluded that on average, 85% of stainless steels are recycled once they reach their end of life, either to become new stainless steels (56%) or a valuable iron source for carbon steels (29%).

METHODOLOGY FOR SLAG LCI CALCULATION | worldsteel

METHODOLOGY FOR SLAG LCI CALCULATION. Steel industry co-products such as blast furnace slag are very often recovered and used as a raw material. For example, this is often the case where blast furnace slag is used in the construction sector, replacing the need for clinker. The steel industry has developed a methodology to calculate the life cycle inventory (LCI) for the slags from the steelmaking processes.

Sequestration of carbon dioxide in steel slag

The slag is alkaline in nature and rich in Ca and Mg oxides. Upon use the oxide interact with atmospheric CO 2 and form carbonates, making them unstable. Storing CO 2 in the slag would make it more stable, enhances its life cycle and promotes further usage in various applications. CO 2 sequestration can be done through carbonation of steel slag.

The use and advantages of slag - voestalpine

Jan 10, 2014 · LD slag has a series of advantages over natural rock in the field of road construction. Greater hardness. Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. This is the result of its mineral composition. The consequences: less wear and longer road lifetimes. Roads constructed using LD slag demonstrate reduced rutting.
