This work investigates the geochemical response of carbonate reservoir rocks to CO₂-enriched fluids, focusing on mineralogical changes and potential geological storage consequences. Laboratory experiments involved Žarošice field (Czech Republic) dolomite rock and in situ representative pore water. The findings show that CO₂ injection causes carbonate and feldspar dissolution, causing a detectable porosity increase (~0.25 percentage points). These findings lay the groundwork for assessing the potential of using dolomitized carbonate rocks for pilot CO₂ sequestration projects in Central Europe. Full article

Septic wastewater, or septage, represents a specific type of wastewater with a high concentration of organic matter and significant variability in composition, which places increased demand on its treatment. With the increasing pressure for decentralized solutions for small areas with no established sewage infrastructure, technologies that can ensure stable operation of the treatment plant are coming to the fore. This paper compares the technologies used for septic wastewater treatment, i.e., sequencing batch reactor (SBR), membrane bioreactor (MBR), and aerobic granular sludge reactor (AGS). For the AGS technology, a trial run of a selected wastewater collection plant is carried out. Full article

One of the key goals of the 2030 Agenda for Sustainable Development is to create inclusive, safe, resilient, and sustainable cities. A fundamental aspect of this goal is ensuring barrier-free mobility and access to public spaces, particularly for people with physical and visual impairments, seniors, and others with limited mobility. This paper discusses the statistical background of persons with disabilities in the Czech Republic and identifies the main obstacles they face in independent movement and spatial orientation. Based on current data, regulations, and practical observations, the paper outlines principles and design recommendations that support accessible and inclusive public environments. These include both physical modifications for mobility and tactile or visual systems that assist in independent navigation for visually impaired users. Full article

The D1 Paskov spoil heap is a smaller brownfield covering an area of 71,188 m², located in the former Paskov mining region. It serves as a model area for reclamation planning, based on a comprehensive assessment of its natural conditions and the risks posed by contamination from hazardous elements and erosion processes. Data for this assessment was collected through field research conducted between 2023 and 2025. In September 2023, additional fieldwork and mapping were carried out using unmanned aerial vehicles equipped with two types of sensors: an RGB camera and LiDAR. The dump is primarily covered with ruderal vegetation, with the summit plateau dominated by the expansive grass species Calamagrostis epigejos. With appropriate management, the plant communities on the western and northern slopes have the potential to develop into conservation-significant habitats. However, the southwestern slope presents challenges due to active rill erosion and contamination. Stabilization measures are required to prevent further degradation in this area. Full article

Digitalization is becoming one of the key trends in contemporary construction, playing a particularly important role in the building operation phase. This phase represents the longest period of a building’s life cycle and is simultaneously associated with high operational costs. The aim of the presented research was to analyze the views of experts and professionals working in the field of building management and operation on the use of digital tools, their perception of the level of digitalization, and the potential for further development. The research was conducted in the form of a questionnaire survey. The results show that in most cases, basic software tools prevail, while the use of advanced platforms such as CMMS (Computerized Maintenance Management System) or CAFM (Computer-Aided Facility Management) systems remains limited. Only one quarter of respondents actively use IoT sensors, which represent an innovative element with high potential for efficient building operation and sustainability. Paradoxically, some respondents perceive even the use of basic software as representing significant digitalization. The most digitalized areas include financial administration, security systems, and energy management, while digital building passports and workspace management remain on the periphery. The findings highlight the uneven application of digital tools and the need for their broader implementation, which can significantly contribute to the efficiency and sustainability of building management.

This study investigates the remediation of contaminated soil containing potentially toxic elements (PTEs) through phytoremediation. Cannabis sativa was selected as the model species due to its suitability for cultivation under Central and Northern European climatic conditions. The experiment was conducted over an eight-month period, during which no visible morphological deformities were observed, despite elevated concentrations of PTEs. Among the tested soil samples, the plant labeled No. 5 exhibited the highest remediation efficiency, removing approximately 11% of total zinc, nearly 75% of chromium, 36% of nickel, just under 9% of copper, and about 36% of arsenic from the soil.

The study is devoted to the remediation of contaminated soil with the presence of potentially toxic elements by flotation. The research summarizes the results concerning the verification of the effectiveness of selected flotation agents at different doses. Kerosene and potassium ethyl xanthogenate were used as reagents. Application of these two reagents simultaneously and flotation without the use of a collector were also tested. The flotation tests showed that similar results were obtained with kerosene, which is a non-polar collector, as with the polar potassium ethyl xanthogenate, which as an anionic collector is designed specifically for metal flotation. Interesting results were also achieved in flotation without the use of a collector. Full article

A technology aimed at reducing extremely high water hardness in Chotěšov, a village in the Czech Republic, was developed and tested. Three treatment methods were evaluated under laboratory conditions: softening filtration using a cation exchange resin in the Na⁺ cycle (resulting in a 72% reduction in hardness); nanofiltration (NF); and reverse osmosis (RO), which reduced hardness by 71% and 96%, respectively. The mixing of the permeate with treated groundwater at a volume ratio of 1:1 resulted in a further reduction in hardness to 41% with NF permeate and to 53% with RO permeate, relative to the original value.

The key topic of this article is the attempt to take a comprehensive and not always reflected approach to environmental protection in the Ostrava-Karviná agglomeration. It emphasizes the importance of environmental interactions between humans and the landscape, which allow the emergence of environmental-interaction elements. These elements work with a balanced combination of top-down and bottom-up approaches in environmental protection. The research is based on the recognition that one of the key environmental problems of the Ostrava-Karviná agglomeration is the disturbed relationship of inhabitants to the landscape, which negatively affects their willingness to participate in its protection. Within the framework of the work, environmental-interaction elements at model sites of the Ostrava-Karviná agglomeration are identified and analyzed, and their potential for integration into environmental protection systems is assessed.

This paper deals with the removal of selected micropollutants from water in the laboratory, namely the removal of pharmaceuticals using the sorption materials Filtrasorb F100 and Filtrasorb F400. A group of well-known and available pharmaceuticals was selected for the experiment, which were the over-the-counter analgesics Ibuprofen, Diclofenac, Naproxen and Paracetamol. The model water was created by mixing drinking water from the water supply system of the city of Brno and standards of these pharmaceuticals prepared in the accredited laboratory of ALS Czech Republic. Water filtration was carried out through two filter columns, each filled with a different type of Filtrasorb sorbent. The filtered water was collected at selected time intervals (1, 2, 4 and 6 min) for analysis. The measurements showed that Filtrasorb F100 and Filtrasorb F400 activated carbons have comparable efficiency for the removal for Ibuprofen, Diclofenac, Naproxen and Paracetamol (around 83%). Both activated carbons have proven to be reliable sorbents for the removal of selected micropollutants from water. Full article

The study assesses water-filled subsidence basins in the Karviná region using ecological and faunistic characteristics, with freshwater molluscs as bioindicators. Two sites—subsidence lake Kozinec and Doubrava basins—differing in size, salinity, and vegetation, were examined. A malacological survey identified 16 mollusc species, with invasive species dominating Kozinec due to high salinity from mine water discharge, while native species prevailed in Doubrava basins. The study analysed the impact of shoreline zones on mollusc communities, measured physicochemical water parameters (e.g., salinity, pH, nitrites), and evaluated anthropogenic influences. Proposed measures include raising the dam to prevent salinisation of Kozinec’s isolated section, supporting ecological succession, and protecting littoral zones, highlighting the potential for revitalising post-mining sites.

This study explores the effectiveness of ultraviolet (UV) irradiation, ozonation (O₃), granular activated carbon (GAC) adsorption, and their combinations (UV/GAC, O₃/GAC) in removing selected pharmaceuticals and common wastewater micropollutants under controlled laboratory-scale conditions. Eight target compounds—candesartan, irbesartan, valsartan, metoprolol, diclofenac, metformin, sucralose, and caffeine—were identified and quantified in real wastewater samples collected from a municipal wastewater treatment plant. Ozonation proved to be the most effective standalone method, achieving complete removal (100%) of five pharmaceuticals and partial removal of sucralose (~60%) and metformin (~17%). The combined O₃/GAC treatment further enhanced overall removal efficiency. In contrast, UV irradiation alone showed limited effectiveness. Importantly, all substances except metformin were fully removed by at least one of the tested methods. These findings underscore the potential of advanced and hybrid treatment technologies—validated here at the laboratory scale—for improving pharmaceutical removal from wastewater and mitigating their environmental impact.

This study explores the bioleaching potential of indium from Liquid Crystal Display (LCD) screens originating from end-of-life mobile phones using Acidithiobacillus spp. The LCD panels were mechanically processed, including dismantling, crushing, and milling, and separated into four size fractions: <1 mm, 1–1.5 mm, 1.5–2 mm and >2 mm. These fractions were leached for a period of four weeks. During the experiment, changes in pH value were monitored, and the concentrations of indium in the solutions were measured by using inductively coupled plasma optical emission spectrometry (ICP-OES). The results showed that the highest indium was detected after 4 weeks of leaching for fraction FG <1 mm (146.47 mg/L). The study confirms that bioleaching is an effective and environmentally friendly method for the recovery of critical raw materials such as indium from electronic waste, offering a promising alternative to conventional chemical and pyrometallurgical techniques.

In this study, the Purolite MB400 ion-exchange resin was investigated for its capacity to simultaneously remove metal cations (Cu, Zn, Fe) and sulphates from model solutions. The highest efficiency was observed in the CuSO₄ model solution (10 mg/L), where Cu²⁺ removal reached 97.8% and SO₄²⁻ removal 95.1%. However, increasing concentrations of metals and sulphates resulted in a gradual decline in removal efficiency. Full article

Construction is one of the largest industries, exerting a significant influence on the environment, economy, and society. With the growing emphasis on sustainability, efficiency, and minimizing negative impacts, it is essential to apply innovative tools and approaches across all phases of a building’s life cycle. This article focuses on the life cycle of buildings as a comprehensive process, covering stages from planning and construction to use and eventual disposal. Special attention is given to the integration of Life Cycle Costing (LCC) as a key methodology for evaluating both the environmental and economic aspects of sustainability. The presented case study compares two construction variants a prefabricated timber structure and a traditional masonry system highlighting the differences in cost distribution and economic demands. The findings confirm that the construction and operation phases account for the dominant share of life cycle costs, with their significance particularly increasing in larger projects. These results underline the necessity of comprehensive life cycle evaluation and emphasize the importance of modeling economic aspects as an integral part of sustainable construction. Full article

This study aims to provide a comprehensive assessment of the ecological status of two distinct sections of the Bílovka stream located in the Moravian-Silesian Region of the Czech Republic. The evaluation was conducted using the standardized HEM 2014 methodology, which assesses seventeen hydromorphological indicators across three spatial zones: the channel, the bank/riparian zone, and the floodplain. A comparative analysis between a near-natural reach and a section significantly modified by human activities revealed notable differences in ecological quality. The findings underscore the practical relevance of the HEM 2014 methodology for evaluating the current hydromorphological condition of watercourses and for informing the design of targeted restoration measures, particularly within urbanized landscapes.

Road critical infrastructure, especially bridges, is vulnerable to threats such as extreme weather, traffic overload, accidents, and natural disasters, which can compromise stability or operability. Timely mapping of these threats and modeling crisis scenarios are vital for resilience. This study explores how Virtual Operations Support Teams (VOSTs) can enhance threat mapping and scenario modeling. VOSTs collect real-time data (e.g., from social media and sensors) and produce digital maps and analyses to improve situational awareness. The study focuses on the types of data VOSTs gather and the resulting changes in mapping procedures and scenario parameters. The findings indicate that integrating VOST capabilities supports more effective crisis planning and response for road infrastructure management. Full article

This article deals with the potential use of by-products from Třinecké železárny company—namely steelworks slag and spent foundry sand (SFS)—as an alternative to natural aggregate in the production of high-strength concrete. The aim of the study was to design and experimentally verify two concrete mixtures. For the first mixture (Mixture 1), natural aggregate was fully replaced by steelworks slag. For the second mixture (Mixture 2), the replacement was made by a combination of steelworks slag and SFS in the same volume ratio. The results have shown that Mixture 1 achieved a strength class of C70/85 and was classified as high-strength concrete. In contrast, Mixture 2, despite optimization of the composition, only achieved a strength class of C35/40, which does not allow for its classification as high-strength concrete. Full article

This study investigates the potential use of black coal mining waste as a feedstock for plasma gasification. A national database of coal waste heaps was developed based on standardized criteria such as heap volume (>100,000 m³), accessibility, and environmental risk. From six initially sampled sites, two active and unreclaimed heaps—Jan Karel (Karviná) and Paskov D (Ostrava)—were selected for detailed material analysis due to their favorable characteristics. Subsequent plasma gasification experiments were conducted using sorted coal waste fractions at a temperature of 1600 °C in a pilot-scale plasma reactor. Four trials were performed with fuel flow rates of 15 and 20 kg/h and varying steam/fuel ratios (0.6, 1.0, and 1.3). The results revealed a high syngas yield of up to 92% by volume. Increasing the steam/fuel ratio led to higher hydrogen and carbon dioxide content in the syngas, while lower ratios favored carbon monoxide and trace methane formation. Volt-ampere characteristics of the plasma torch showed that higher nitrogen flow rates required higher voltage to maintain a stable arc. The findings confirm the technical feasibility and efficiency of converting selected coal mining waste into valuable syngas, supporting its future use in advanced waste-to-energy technologies.

The aim of this research was to evaluate the impact of revitalization measures implemented in the catchments of the Vortovský Stream and the Valčice Stream, located within the protected landscape area of the Žďárské vrchy in the Pardubice Region, Czech Republic. The assessment was conducted using rainfall–runoff models HEC-HMS 4.13(The Hydrologic Engineering Center’s-Hydrologic Modeling System) and MIKE SHE version 2020 (MIKE System Hydrological European), and hydraulic models HEC-RAS 6.6 and MIKE 11 version 2020. The study focused on comparing the effects of revitalization on flow velocity in the Valčice Stream with its original state, evaluating the ability of the reconstructed ponds Malý Černý and Velký Černý to transform flood waves, and assessing the overall effectiveness of the revitalized areas in water retention within the landscape. The results demonstrate that the reconstruction of the ponds on the Valčice Stream significantly contributed to the safe transformation of flood flows, and that the revitalization of part of the stream resulted in a reduction in flow velocity in the channel. Furthermore, the revitalization measures in the Vortovský Stream catchment were found to have a positive effect on enhancing water retention in the area. Full article

The paper focuses on the analysis of the impacts of climate change on the economic performance of the studied brownfield industrial park in the Upper Nitra region of Slovakia. The aim of this paper was to suggest ways of eliminating possible negative environmental burdens and the creation of site reclamation as a result of the termination of mining and the elimination of adverse environmental impacts in the selected region. The intention was to present the main causes of the decline of mining activity, with its environmental, economic and social consequences of the end of mining. The natural conclusion of the mining process is the comprehensive revitalisation of the area affected by mining activities. We have analysed the process of revitalisation of water areas and systems affected by mining activities and quantified the amount of investments needed for this revitalisation. Full article
