Chemical composition analysis of raw materials used in iron ore sinter plants in Poland

The main goal of the study was the analysis of the chemical compositions of raw materials used in iron ore sinter plants in Poland. The iron ore sintering process is the largest source of emissions of dust and gas pollution in the iron and steel industry. Hematite ores, magnetite concentrates, admixtures (dolomite, limestone and burnt lime), fuels (coke breeze, anthracite) and by-products are used in Poland to produce the sinter mixture

Harmful admixtures assessment in sinter mixtures used in iron ore sinter plants in Poland

In this study composition of sinter mixtures used in Polish sinter plants were established. Seven sinter mixtures composition were examined, based on iron-bearing materials, admixtures and fuels. Contents of harmful admixtures were examined according to three kinds of environmental impacts: emissions of SOx, heavy metals, polychlorinated dibenzodioxins and polychlorinated dibenzofurans (PCDDs/PCDFs)

Depletion of abiotic resources in the steel production in Poland

Steelmaking processes consume a lot of energy and materials, therefore researchers are constantly looking for new ways of reducing the consumption of resources in the production processes. The main purpose of the article is to present abiotic resource depletion the in steel production in the case of integrated steelmaking route in Poland and its role in life cycle assessment. There are different methods of life cycle assessment for abiotic resources, the use of which affects the quality of the obtained information. The article presents some results of life cycle assessment of abiotic depletion

Water scarcity assessment of steel production in national integrated steelmaking route

The main goal of the study was the assessment of the water scarcity in steel production in integrated steelmaking route in Poland. The main goal of Water footprint (WF) is quantifying and mapping of direct and indirect water use in life cycle of product or technology. In the paper Water Scarcity Indicators (WSI) for steel production and unit processes in integrated steelmaking route was performed

Innovative technologies for greenhouse gas emission reduction in steel production

The main goal of the study was to present the most significant technological innovations aiming at reduction of greenhouse gas emission in steel production. Reduction of greenhouse gas and dust pollution is a very important aspect in the iron and steel industry. New solutions are constantly being searched for to reduce greenhouse gases (GHG). The article presents the most recent innovative technologies which may be applied in the steel industry in order to limit the emission of GHG. The significance of CCS (CO2 Capture and Storage) and CCU (CO2 Capture and Utilization) in the steel industry are also discussed

An environmental evaluation of food waste downstream management options: a hybrid LCA approach

Food waste treatment methods have been typically analysed using current energy generation conditions. To correctly evaluate treatment methods, they must be compared under existing and potential decarbonisation scenarios. This paper holistically quantifies the environmental impacts of three food waste downstream management options—incineration, composting, and anaerobic digestion (AD). Methods The assessment was carried out using a novel hybrid input–output-based life cycle assessment method (LCA), for 2014, and in a future decarbonised economy. The method introduces expanded system boundaries which reduced the level of incompleteness, a previous limitation of process-based LCA. Results Using the 2014 UK energy mix, composting achieved the best score for seven of 14 environmental impacts, while AD scored second best for ten. Incineration had the highest environmental burdens in six impacts. Uncertainties in the LCA data made it difficult determine best treatment option. There was significant environmental impact from capital goods, meaning current treatment facilities should be used for their full lifespan. Hybrid IO LCA’s included additional processes and reduced truncation error increasing overall captured environmental impacts of composting, AD, and incineration by 26, 10 and 26%, respectively. Sensitivity and Monte Carlo analysis evaluate the methods robustness and illustrate the uncertainty of current LCA methods. Major implication: hybrid IO-LCA approaches must become the new norm for LCA. Conclusion This study provided a deeper insight of the overall environmental performance of downstream food waste treatment options including ecological burdens associated with capital goods. Keywords Anaerobic digestion Incineration Composting Food waste Hybrid life cycle assessment Capital good

Application of environmental assessment methods based on life cycle analysis for the automotive industry

W pracy przedstawiono możliwości zastosowania nowych metod oceny środowiskowej na podstawie podejścia cyklu życia w branży motoryzacyjnej. Na podstawie dokonanego przeglądu literatury stwierdzono, że dotychczas stosowaną metodą oceny środowiskowej w branży motoryzacyjnej jest metoda „od szybu do koła” (WTW, Well-To-Wheel). Na podstawie dokonanej analizy porównawczej oceny cyklu życia LCA (Life Cycle Assessment) i WTW wykazano wiele korzyści związanych z zastosowaniem metody oceny cyklu życia w branży motoryzacyjnej.The paper presents the potential use of new methods of environmental assessment based on life-cycle-assessment (LCA) in the automotive industry. Based on the literature review found that the up till now the method of environmental assessment in the automotive industry is the method Well-To-Wheel (WTW). Based on the comparative analyzes of LCA and WTW demonstrated many benefits of LCA. The study also presents challenges related to environmental assessments in the automotive industry under the new requirements of circular economy
