Was ist Steel Recycling?
Steel recycling ist ein großer Teil der Stahlproduktion und des Stahlhandels. Es beschreibt den Prozess, bei dem alter Stahl und Stahlschrott gesammelt, verarbeitet und dann wieder zur Herstellung von neuem Stahl verwendet wird. Dieser Kreislaufprozess trägt zur Reduzierung der Umweltbelastung und zur Kosteneinsparung in der Stahlindustrie bei.
Warum ist Steel Recycling wichtig?
Das Recyceln von Stahl ist aus mehreren Gründen wichtig. Erstens trägt es zur Abfallreduzierung bei, da Stahlschrott einen erheblichen Anteil an den Industrieabfällen ausmacht. Zweitens spart es Ressourcen und Energie. Der Energieaufwand für die Verarbeitung von Stahlschrott zur Herstellung neuer Stahlprodukte ist deutlich geringer als der Energieaufwand für die Gewinnung von Eisenerz. Drittens trägt es zum Schutz der Umwelt bei. Mit dem Recycling von Stahl wird auch die Zahl der Abbaustätten für Eisenerz gesenkt.
Der Prozess des Steel Recyclings
Der Prozess des Steel Recyclings besteht im Wesentlichen aus drei Schritten. Zu Anfang wird der Stahlschrott gesammelt und sortiert. Nach der Sortierung wird der Schrott zur Stahlschmelze transportiert. Dort wird er geschmolzen und in eine Form gebracht, die die Basis für neue Stahlprodukte bildet. Diese Produkte reichen von Baustahl bis hin zu Haushaltswaren.
Die Rolle des Steel Recyclings im Stahlhandel
Im Stahlhandel spielt Steel Recycling eine wichtige Rolle. Recycelter Stahl ist oft günstiger als neu produzierter Stahl. Dadurch kann der Handel mit recyceltem Stahl selbst in Zeiten niedriger Stahlpreise profitabel sein. Zudem spricht auch der ökologische Aspekt viele Unternehmen und Verbraucher an, wodurch die Nachfrage nach recyceltem Stahl steigt.
