Natural carbonation of unground steelmaking slag for assessment of direct carbon sequestration potential during outdoor storage

Journal of CO2 Utilization
CO2 sequestration using steelmaking slag remains challenging for practical applications: one of the main barriers is the energy and costs required for accelerated carbonation. In Japan, steelmaking slag is often stored in outdoor yards for several months,

Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

steel research international, EarlyView.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

steel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Output Quality, Productivity, and Demand: Evidence from the Chinese Steel Industry

The RAND Journal of Economics, EarlyView.
ABSTRACT Unobserved objective output quality complicates the analysis of firm productivity and demand because higher‐quality products entail higher costs but offer greater consumption benefits. Using a panel of firms with output quality data, we decompose quantity‐based productivity into fundamental productivity and the costs of quality, and separate ...

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Sustainable Photovoltaics: Optimising Material Consumption, Cost and Environmental Performance Through Smart Sustainability Approaches for Crystalline Silicon Solar Photovoltaics

Solar RRL, Volume 10, Issue 11, 15 June 2026.
A sustainability framework shows that photovoltaics can simultaneously improve material security, reduce costs, and improve environmental performance. Updated learning curves reveal declining material intensity and emissions alongside rising energy return on investment, EROI (> 25).
