Comparison of Two Steel Production Global Warming Potentials in Terms of Scrap Consumption by Using Life Cycle Assessment

Abstract

The European steel industry is striving to decrease both direct and indirect CO2 emissions. Achieving low CO2 emission levels requires cutting current emissions by 80-95% by 2050. Concurrently, governments are enacting stricter legal regulations to shift steel producers toward greener practices. Therefore, a managed transition and technical solutions are essential. Understanding global warming potential (GWP) mechanisms and emission ratios is crucial for sustainable steel production. This study aims to compare two integrated steel plants using the same methodology. Although these plants share the same process routes, their capacities and scrap usage ratios differ. Scrap usage in the Basic Oxygen Furnace (BOF) process directly affects the global warming potential results. Consequently, the primary focus of the present study is on scrap consumption. Currently, scrap consumption is 204.6 kg per ton of steel in Plant A, whereas it is 184.7 kg per ton of steel in Plant B. Furthermore, external scrap accounts for 78.0% of the total scrap in Plant B, compared to 37.2% in Plant A. As a result, the CO2 equivalent emissions related to external scrap usage in Plant B are 1.71 times higher than those in Plant A.

Abstract

Avrupa çelik endüstrisi, doğrudan ve dolaylı CO2 emisyonlarını azaltmaya çalışmaktadır. Düşük CO2 emisyon seviyelerine ulaşmak, 2050 yılına kadar emisyonların %80-95 oranında azaltılması anlamına gelmektedir. Bu arada, çelik üreticilerini daha çevreci (yeşil) alanlara yönlendirmek amacıyla hükümetler tarafından yasal kısıtlamalar yürürlüğe konmaktadır. Yönetilen bir geçişe ve teknik çözümlere ihtiyaç duyulmaktadır. Bu nedenle, sürdürülebilir çelik üretimi için küresel ısınma potansiyeli mekanizmasını ve emisyon oranlarını anlamak büyük önem taşımaktadır. Bu çalışma, aynı yöntemi kullanarak iki entegre çelik tesisini karşılaştırmayı amaçlamaktadır. Bu tesisler aynı proses adımlarına sahiptir; ancak kapasiteleri ve hurda kullanım oranları birbirinden farklıdır. BOF (Bazik Oksijen Fırını) prosesindeki hurda kullanımı, küresel ısınma potansiyeli sonuçlarını etkilemektedir. Bu yüzden, mevcut çalışmada odak noktası hurda tüketimi olarak belirlenmiştir. Mevcut durumda hurda tüketimi, A Tesisinde ton çelik başına 204,6 kg iken, B Tesisinde ton çelik başına 184,7 kg'dır. Öte yandan, dış hurda tedarik oranı B Tesisinde %78,0 iken, A Tesisinde bu oran %37,2'dir. Dış hurda kullanımından kaynaklanan CO2 eşdeğeri açısından B Tesisi, A Tesisinden 1,71 kat daha yüksek bir değere sahiptir.
