Wastewater has high potential as an energy source. Therefore, it is important to recover even the smallest part of this energy, e.g., in microbial fuel cells (MFCs). The obtained electricity production depends on the process rate of the electrodes. In MFC, the microorganisms are the catalyst of anode, and the cathode is usually made of carbon material. To increase the MFC efficiency it is necessary to search the new cathode materials. In this work, the electricity production from yeast wastewater in membrane-less microbial fuel cells with a carbon felt, Ni-Co, Cu-B, and Cu-Ag cathodes has been analyzed. In the first place, the measurements of the stationary potential of the electrodes (with Cu-Ag catalyst obtained by the electrochemical deposition technique) were performed. Next, the analysis of the electric energy production during the operation of the membrane-less microbial fuel cell (ML-MFC). The highest parameters were obtained for the Ni-Co and Cu-Ag catalysts. The cell voltage of 607 mV for Ni-Co and 605 mV for Cu-Ag was obtained. Additionally, the power of 4.29 mW for both cathodes - Ni-Co and Cu-Ag was obtained. Moreover, Ni-Co and Cu-Ag allow the shortest time of COD reduction. Based on the test results (with selected MFC design, wastewater, temperature, etc.), it can be concluded that of all the analyzed electrodes, Cu-Ag and Ni-Co electrodes have the best parameters for use as cathodes in ML-MFC. However, based on the results of this study, it can be concluded that all the tested electrodes can be used as cathode material in MFC.

Due to the constant growth of the world's population, the amount of generated wastewater is also constantly increasing. One of the devices that can use wastewater as a raw material for energy production is a microbial fuel cell (MFC). MFCs technology is constantly evolving. However, to increase its use, it is necessary to improve its efficiency. There are various possibilities to ensure this, such as the use of new electrode materials, new cell designs, or the use of wastewaters from different sources. In this paper the analysis of MFC operation (cell voltage, power, and current density) fed by mixed municipal and industrial wastewaters was shown. Moreover, the change in time of COD was analyzed. Due to cost reduction the membrane-less microbial fuel cell (ML-MFC) was chosen. It was noted that the addition of concentrated process wastewater increases the COD reduction time in the ML-MFC. An increase of generated bioelectricity during fed ML-MFC by mixed municipal and industrial (process wastewater from yeast production) wastewater was demonstrated. The highest values of average cell voltage (598 mV), maximum power (4.47 mW) and maximum current density (0.26 mA·cm-2) were obtained for a 10% share of yeast process wastewater in the mixed wastewater, which fed the ML-MFC.

Currently, it is estimated that the construction sector consumes over 40% of the energy produced and about 50% of the mass of processed materials. As a consequence, there is a challenge to look for alternative material solutions allowing for the storage and conversion of energy. Phase change materials give us such opportunities. Their introduction leads to additional benefits related to thermal parameters. The work presents a short overview of PCMs along with the possibility of their application. Then, as part of the research, the selected phase change material was applied to the internal plaster layer of an external wall to check its activity. The obtained results were compared to the values of reference samples (without PCM). The proposed solution leads to the improvement of the analyzed partitions' thermal parameters.

The article discusses current trends in designing green and eco-friendly façades of buildings of different functions in Poland and around the world. Information collected on completed façade projects, associated research and conclusions formulated on the basis thereof, indicate trends and possibilities for the use of contemporary material solutions and technologies in designing various forms of vertical 'greenery’ which support sustainable development of urban areas. The main objective of the research was to identify the most important features of green façades as eco-friendly architectural solutions. A case study with descriptions of the features and qualitative elements of 100 of the most architecturally interesting buildings with characteristic external wall structures was constructed for research purposes. The sites selected for the case study represent a review of global trends. The data was then used for a multi-criteria analysis of green façade systems from the perspective of eco-friendly architectural solutions. The conducted research, analyses and discussions on solutions already in place were then implemented as guidelines for innovative architectural design solutions, which were presented at the Faculty of Architecture at Poznań University of Technology in the form of selected diagrams and student visualisations. These comprised highly aesthetic compositions, possible to implement in the near future.

The aim of this article is to address the influence of air humidity and testing temperature on the thermal conductivity coefficient (λ) of various thermal insulation materials. This group includes wood-based materials, rock wools, heat-insulating renders, climate boards, and lightweight cellular concretes. These materials are used both indoors and outdoors in buildings. Over the course of several years, data were collected from laboratory tests to determine the thermal conductivity coefficient (λ) in relation to increases in temperature and humidity. The obtained results were compared with values provided by the manufacturers of the insulation materials. The aforementioned research was carried out due to the rather high sorption of most materials and thus the possibility of them becoming humid at high air humidity. Because of the very large difference in the thermal conductivity coefficient of water and air, a relatively small increase in the mass moisture content of the materials results in a loss of insulation.

The European Union in the Industry 5,0 proposal encourages technological transformation. ICT Information and Communications Technology, which for the AEC industry are BIM and Digital Twin is appreciated, but also innovative and variable over time. Therefore publications like this, which verify the validity of information are important. Global BIM policy analysis can be valuable for stakeholders of the investment process, policymakers, researchers. The authors performed a scientific analysis on an extensive database of articles (over 20,000) as well as national regulations (in non-English languages). BIM mandatory in public investments depicted on the map, also charts showing other indicators. In Eastern Europe has been observed a small scale (22%) of planned BIM requirements. Czech Republic plans BIM mandate on public investments for project above the EU threshold. The Polish road map proposes MacroBIM for risky or complicated, public investments with budget exceeding EUR 10 million since 2025 and for all since 2025. Comparing with other indicators the Czech Republic and Poland have high GDP per capita and percentage of the industrial sector (including construction) in GDP value added. Poland is classified also as a developed market within the global equity indices. This may have an impact on digital transformation, which is a demanding project due to investment costs. Bulgaria did not include a BIM mandate in its digital transformations plan. Due to the Industry 5,0 and the positive results from case studies of countries that have already applied BIM mandatory introducing BIM requirements in public procurements should be motivated and supported.

Theft and devastation of railway infrastructure are one of the most important factors that affect the safety of the railway transport system. In Poland, the railway transported 245.1 million passengers and 243.6 million tons of cargo in 2021, so it is extremely important to ensure the maximum possible safety standards. Theft and devastation of railway infrastructure contribute to significant material damage to railway network managers. The costs of rebuilding railway equipment are estimated at millions of zlotys every year. They also influence the proper functioning of railway traffic. Due to this phenomenon, there are delays of passenger and freight trains, the total of which amounted to over 100,000 minutes in 2021. Therefore, the effects of such hooligan acts also affect passengers and commercial customers of the railways. The article is an attempt to describe the impact of theft and devastation of railway infrastructure on its safety and the operation of railway lines in Poland. By analyzing the available statistical data and using the CSM method, as well as applying certain simplifications, it was possible to determine the approximate level of risk using techniques used in practice. Based on the adopted risk reference levels, a systematic reduction in both the probability of occurrence of negative phenomena and their consequences was observed.

Concrete is the most synthesized material in construction sector which it has aggregate as one of its components. The use of natural aggregate in concrete preparation uses a significant amount of non-renewable resources and energy, having a significant environmental impact. Multiple research projects have been conducted to safeguard natural reserves, seeking a solution to the waste disposal issue, and reduce construction costs by utilizing waste materials. FA(Fly Ash) aggregate is one such material that can be a replacement for natural aggregate. Durability parameters of concrete with Fly Ash (FA) aggregate are studied in this work as an alternative for fine aggregate. In this study, 5 concrete mixes were prepared utilizing FA aggregate in percentage substitution of 0%, 10%, 20%, 30%, and 40% for each. The quantity of cement, compaction, curing rate, concrete cover, and porosity all influence the durability of the concrete. Concrete attributes such as strength in compression, retaliation to abrasion and half-cell potential were investigated. Durability parameters of the specimens were tested after 90-day curing. The results revealed that concrete with 30% FA aggregate had the highest compressive strength, improved resistance towards abrasion and least half cell potential values. Experimentation data were used to develop comprehensive prediction models by applying support vector machine (SVM) algorithm. The SVM model analyses R2 values with an accuracy of over 97%. As a result, we can use SVM to efficiently execute prediction modelling in construction area.

The functioning of societies involves the generation of large amounts of municipal waste. This study analyses the amounts of pollutants emitted during waste incineration at selected waste incineration plants in 2022. Four plants were analyzed, including three with the highest waste processing efficiency (Copenhagen, Poznan and Kraków) and one with the lowest efficiency (Konin). The choice of the factory in Copenhagen was also dictated by its strategic location in the city center. Analysing the emissions from the selected plants it can be concluded that environmental safety was maintained and none of the plants exceeded the permissible emissions value.

The purpose of this work is to present the possibilities of using tacheometric measurement technology in the development of a 3D geometric model of an existing building and the directions of using BIM technology in the process of building operation. General information on the development of BIM technology was presented, and issues related to the construction of 3D models were discussed. Attention was also drawn to the need to update the information assigned to the model on an ongoing basis in order to effectively manage the building. Supplementing the model with metadata regarding the building materials used will allow for a precise and quick analysis of all renovation assumptions. The created 3D model can be used to control the condition of structures or in safety and risk management.
