“…Accordingly, deeper research has been conducted to establish a relative price-strength relationship. The online website Vosta Stahlhandel Gmbh [19] and other mill pricelists (US Steel Kosice 2017 [20], Tata 2015 [21], Salzgitter [22], Voestalpine [23], Arvedi [24] and SSAB [25]) contain their respective grade extras for hot-rolled coils. All these values are scattered with a bi-linear interpolation of the mean values in Figure 1.…”

Environmental impact awareness in civil engineering is nowadays an important concern. The last message from the IPCC (Intergovernmental Panel on Climate Change) was clear: significant actions are mandatory and urgent to achieve the objective to limit global warming to 1.5°C. The building sector is one of the most polluting industrial sectors for which economically viable solutions must be found to cut the emissions. The development of new production technologies can contribute to this aim by creating innovative and more sustainable materials. Amongst the new materials that appear on the steel market, high strength steels are a nice example as they offer higher strength to weight ratio of structural steel elements, resulting in material savings, lighter foundations, easier transportation, and erection. These multiple advantages explain why the use of high strength steels could lead to both significant carbon emission and cost savings. However, the production of such steels uses more alloying elements and sometimes they require more production energy than for regular grades. The aim of this paper is to estimate the relative prices and relative carbon emissions of high strength steels to evaluate whether they constitute sustainable materials. This paper demonstrates that, in many cases, the increase of relative prices and carbon emissions as function of yield strength can be negligible by contrast to the weight savings induced by using high strength steels.

“…Energy efficiency may be improved by 15% to 20% in iron and steel manufacturing processes, according to recent research by Talaei et al [56]. It is possible to reduce greenhouse gas emissions by enhancing energy efficiency, which can be accomplished through improved energy and heat recovery from process gases, products, and effluents; better fuel delivery through the use of pulverized coal injection; better design of furnaces and control systems; and reduced temperature cycles, which can be accomplished via improved system pairing, such as those in Endless Strip Production (ESP) [57]. It is envisaged that several developing technologies, including carbon capture and storage (CCS), hydrogen direct reduction [58], and iron ore electrolysis, would aid in the sector's carbon decarbonization in the not-toodistant future [59].…”

Greenhouse Gas Emissions in the Industrial Processes and Product Use Sector of Saudi Arabia—An Emerging Challenge

The Kingdom of Saudi Arabia has been experiencing consistent growth in industrial processes and product use (IPPU). The IPPU’s emission has been following an increasing trend. This study investigated time-series and cross-sectional analyses of the IPPU sector. Petrochemical, iron and steel, and cement production are the leading source categories in the Kingdom. In recent years, aluminum, zinc, and titanium dioxide production industries were established. During the last ten years, a significant growth was observed in steel, ethylene, direct reduce iron (DRI), and cement production. The growth of this sector depends on many factors, including domestic and international demand, socioeconomic conditions, and the availability of feedstock. The emissions from IPPU without considering energy use was 78 million tons of CO2 equivalent (CO2eq) in 2020, and the cement industry was the highest emitter (35.5%), followed by petrochemical (32.3%) and iron and steel industries (16.8%). A scenario-based projection analysis was performed to estimate the range of emissions for the years up to 2050. The results show that the total emissions could reach between 199 and 426 million tons of CO2eq in 2050. The Kingdom has started initiatives that mainly focus on climate change adaptation and economic divergence with mitigation co-benefits. In general, the focus of such initiatives is the energy sector. However, the timely accomplishment of the Saudi Vision 2030 and Saudi Green Initiative will affect mitigation scenarios significantly, including in the IPPU sector. The mitigation opportunities for this sector include (i) energy efficiency, (ii) emissions efficiency, (iii) material efficiency, (iv) the re-use of materials and recycling of products, (v) intensive and longer use of products, and (vi) demand management. The results of this study will support the Kingdom in developing an appropriate climate change mitigation roadmap.

“…The following benefits are reported for the Castrip® process compared to conventional slab casting and hot rolling methods (Worrell et al 2010, Sosinsky et al 2008, Arvedi et al 2008:  Potential energy savings of 80 to 90 percent (compared to thick-slab casting --hot rolling, pickling and cold rolling --thin slab casting saves approximately 1 GJ/t cast steel; Compared to thin-slab casting, the Castrip® process saves approximately 1 GJ/t cast steel)  Greater tolerance of high-residual elements without loss of quality, enabling greater flexibility in ferrous feed sourcing  Potential for higher scrap recycling rates and less dependence on pig iron and HBI  Lower costs for consumables (e.g., molds, rolling cylinders) and improved liquid steel yield (up to 98 percent) are reported for endless strip production …”

Emerging Energy-efficiency and Carbon Dioxide Emissions-reduction Technologies for the Iron and Steel Industry

Iron and steel manufacturing is among the most energy-intensive industries and accounts for the largest share, approximately 27 percent, of global carbon dioxide (CO 2 ) emissions from the manufacturing sector. The ongoing increase in world steel demand means that this industry's energy use and CO 2 emissions continue to grow, so there is significant incentive to develop, commercialize and adopt emerging energy-efficiency and CO 2 emissions-reduction technologies for steel production. Although studies from around the world have identified a wide range of energy-efficiency technologies applicable to the steel industry that have already been commercialized, information is limited and/or scattered regarding emerging or advanced energyefficiency and low-carbon technologies that are not yet commercialized. This report consolidates available information on 56 emerging iron and steel industry technologies, with the intent of providing a well-structured database of information on these technologies for engineers, researchers, investors, steel companies, policy makers, and other interested parties. For each technology included, we provide information on energy savings and environmental and other benefits, costs, and commercialization status; we also identify references for more information.
