This article compares different production, economic, and selected environmental aspects of agroforestry systems in a standard (alley cropping) and a newly proposed design with fast-growing trees grown in short-rotation coppice. Our models of agroforestry systems (AFSs) are as follows: (i) alley cropping AFS with cherry and walnut trees in single r...

This paper presents the methodology and findings of a comprehensive study that in the selected key time milestones (2030, 2040, 2050) assess the ongoing energy transformation and its impacts within the interconnected European electricity system and overall energy security. The study models the expected development of the installed capacities of ind...

The article presents a proposal for a comprehensive methodology for the design of the process of local production of alternative energy fuel. The goal of the methodology is to ensure a local source of renewable fuel (biomass) for the needs of covering the supply of thermal energy to citizens in rural areas. In the first part, the methodology deals...

The article presents a proposal for a comprehensive methodology designed to increase the energy self-sufficiency and overall resilience of rural areas. The methodology aims to maximize the synergy and economic benefit of the agrovoltaic system with the cultivation of the energy crop Miscanthus x giganteus and its use for energy production in CHP so...

The treatment and disposal of sewage sludge is one of the most important and critical problems of wastewater treatment plants. 8.7 million tonnes of dry matter of sewage sludge were produced annually in the European Union in the year 2020. Due to the fact that sewage sludge contains a large number of substances that are not beneficial for human hea...

The treatment and disposal of sewage sludge is one of the most important and critical issues of wastewater treatment plants. One option for sludge liquidation is the production of fuel in the form of pellets from mixed sewage and paper mill sludge. This study presents the results of the combustion of pelletized fuels, namely sewage and paper mill s...

This paper deals with an assessment of the steps taken and planned by the EU (European Union) to achieve its climate neutrality by 2050. Emphasis is placed on the reality of achieving RES (renewable energy sources) in total energy production in individual countries according to the required values for 2030. A detailed analysis of the previously set...

The new Li-ion battery systems used in electric vehicles have an average capacity of 50 kWh and are expected to be discarded when they reach approximately 80% of their initial capacity, because they are considered to no longer be sufficient for traction purposes. Based on the official national future development scenarios and subsequent mathematica...
