Summary: The decarbonisation efforts in the iron and steel industry will lead to a significant increase in electricity consumption, especially with the increased electrification and the switch to hydrogen as iron reductant. This study focuses on the potential demand response strategies for new lowcarbon technologies and finds that hydrogen-based direct reduction of iron with electric arc furnace technology has a much higher potential for electricity cost savings compared to retrofitting blast furnace basic oxygen furnace technology with carbon capture.

Summary: As the European Union takes more actions on the climate emergency, industries that are difficult to reduce energy consumption have gained increased attention, especially the steel industry which is crucial to the European economy. With the development of new hydrogen-based steelmaking technologies, the global steel production and supply chains will shift from relying on low-cost coal resources to low-cost electricity and hydrogen production. This study explores the techno-economic options for three European countries, including Germany, Spain, and Finland, and analyzes different steel supply chain configurations compared to local production.

Summary: The study explored efficient remediation technologies using a combination of sawdust ash, sawdust biochar, and specific plant species to remediate soil contaminated by zinc, cadmium, and arsenic in a mining area. The results showed that for the highest removal rates of the contaminants, Festuca arundinacea combined with 5% material was the most effective treatment, significantly improving soil enzyme environment and microbial community diversity. Furthermore, the study highlighted the potential of using a combination of materials and plants for remediation of PTE-contaminated soil in mining areas.

Summary: This paper explores the market effects of increased forest biomass competition in the iron and steel industry (ISI) when promoting the use of forest-based bio-products. The results indicate an upward pressure on biomass prices, affecting both forest industries and the ISI. Prudence is necessary to consider potential price effects in investment decisions. Increased domestic biomass supply, adjustments of international trade, or revising relevant policies can mitigate the estimated price effects.

Summary: Steel slag is a by-product of steel manufacturing and has been widely used in civil and construction materials in countries like Japan, USA, and EU. However, Vietnam's current utilization is low due to lack of quality control and opportunities for reuse. This study evaluates steel slag production in Vietnam and identifies environmental and quality issues for its use in road construction, suggesting pH adjustment and official guidelines for disposal.

Summary: This article addresses the high-dimensional stochastic optimal control problem faced by an option market maker, showing that it can be handled using an approximation of the portfolio in terms of its vega and modeling volatility with a classical stochastic volatility model. The low-dimensional functional equation characterizing the market maker's problem can be solved numerically using an Euler scheme and interpolation techniques, even for large portfolios. Numerical examples are provided to illustrate the findings.

Summary: Studies have shown significant differences in the bioaccessibility of PTE in soil across different size fractions, with a general trend of higher bioaccessibility in finer size fractions. The relationship between bioaccessibility and soil size fraction varies for different elements, suggesting the need for consensus on methods to determine PTE bioaccessibility for more accurate human health risk assessment.

Summary: Humans have played a significant role as geomorphic agents on Earth since the mid-Holocene, impacting the planet through activities such as domestication, deforestation, agriculture, urbanization, and mining. The concept of the Anthropocene highlights the period in which humans, along with natural forces, have influenced the Earth's surface and biosphere. Soil, as the Earth's skin, serves as a sensitive archive of human-induced changes, preserving traces of man's impact on the environment.

Summary: Soil is a non-renewable natural resource, but current rates of usage and degradation have led to loss of soil for agriculture, habitats, biodiversity, and ecosystems. Constructed soils or technosols, designed to mimic natural soil and support vegetation growth, offer a potential solution to land degradation and urban green problems, especially if made from recycled wastes or by-products with analysis to ensure safety.

Summary: In semiarid environments, the total inorganic carbon in soil can play a key role in storing atmospheric CO2, but not all of it can be accounted for CO2 sequestration. The study aimed to investigate the dissolution of Ca2+ from gypsum in the formation of soil atmospheric carbonates and to quantify different forms of inorganic C pools. Results showed that gypsum contributes significantly to the net accumulation of inorganic C in soil, while the organic C pool was found to be the most important element in fixing atmospheric CO2 in the surveyed semiarid Mediterranean environment.

Summary: The end of life of plastic polymers depends on whether they are considered as waste. Reduction strategies in the coming decades will focus on reducing material quantities, supporting reuse and recycling, incentivizing the collection of low-value plastics, promoting awareness, and streamlining processes. The agricultural sector needs to consider environmental, social, and economic aspects to optimize the recycling process.

Summary: This study characterizes lignite samples from Kapurdi, Giral, and Sonari mines in Rajasthan's Barmer Basin using petrographic and geochemical techniques. The results provide insights into the geochemical properties, hydrocarbon potential, depositional environment, and paleo-climatic conditions of these lignite deposits. The study finds high volatile matter and sulfur concentrations in the Barmer lignite deposits, as well as indications of a wet environment during organic material decomposition. The findings have implications for understanding the coalification profile and hydrocarbon source rock potential in the region.

Summary: The assessment of heavy metal concentrations in agricultural soil is important for crop safety and quality, as well as potential risks to human health. This review analyzed published data on seven heavy metals in Iranian farmland soils and found that nickel and cadmium exceeded permissible levels. Arsenic showed significant contamination in multiple provinces, while lead and cadmium were highly contaminated in Fars province. Overall, the contamination levels of heavy metals in Iranian agricultural soils were relatively low.

Summary: This study analyzed apatite grains from the Angico dos Dias Carbonatite Complex region in Brazil using an electron probe microanalyzer. The results showed that the apatite grains had characteristics of metacarbonatitic lithotypes and some had undergone substitution processes. Statistical analysis helped identify the sources of the apatite grains and confirmed the presence of carbonatitic bodies in the area.
