This article presents the circular-economy-based biorefinery concept developed by the “Biorefinery” research group at the Zittau/Görlitz University of Applied Sciences. The biorefinery concept aims the holistic utilization of plant raw materials and residues, in orders to exploit their entire value creation potential. The material or energetic utilization of all parts of the plants or plant residues results in significant economic and ecological advantages compared to conventional recycling methods and commonly accepted utilization concepts. The biorefinery process of our research group also envisages feeding products made of or contanining natural fibers after their use to a novel recycling process using saprobionthic fungi. As a result of fungal recycling mycelium-based biocomposites are produced and provided for further applications, e.g. in the construction industry or as packaging material. In this way, carbon can be sequestered in the long term and CO2 emissions can be avoided.

The use of mobile platforms can help employees automate manual processes and streamline operations to save time and perform their tasks safely and accurately. A power-assisted vehicle to move weight around the place – solution: inexpensive, easy to apply, reliable, safe. It can adjust to various tasks, operators’ gait, loads up to 500 kg. It is a relatively inexpensive, easy-to-apply, reliable, and safe solution for moving weight. The motivation of the study is to increase efficiency and reduce physical strain on the operator in material handling tasks and to promote the implementation of this smart platform. Artificial intelligence learning methods are applied to adapt to individual operator’s experience, resulting in a personalized and more comfortable interaction with the help of Q-learning algorithm with 256 learning outcomes in adjusting controller settings: damping, mass, stiffness.

Battery Electric Vehicles (BEVs) are widely seen as one of the available options to combat increasing greenhouse gas emissions. However, these vehicles’ use is less widespread than conventional combustion engine vehicles. One reason for this is their still relatively short range and long charging times. For this reason, it is becoming increasingly crucial in BEV development to use the most accurate simulation models that allow the impact on electricity consumption to be analyzed based on changes made to individual powertrain components. To this end, the author’s dissertation deals with developing a simulation model for estimating the power consumption of a BEV powertrain, describing the definition of the efficiency parameters of the individual powertrain components. The results from the simulation model were then compared with measurements performed in a test facility. The maximum deviation of approximately 8% was measured depending on the driving cycle and parameters.

ACC JOURNAL

The ACC JOURNAL is an international scientific journal that came into existence in 2009. The Technical University of Liberec publishes it Four universities (Technical University of Liberec, Czechia; Technical University Dresden – International Institute Zittau, Germany; University of Applied Sciences Zittau/Görlitz, Germany; Wroclaw University of Economics and Business, Poland) have joined in the Academic Coordination Centre Nisa (ACC) participate in its production. There are usually three issues per year. The ACC JOURNAL is a periodical publishing original reviewed scientific papers, scientific studies, papers presented at conferences and summaries of findings of research projects. The first issue contains contributions focused on natural sciences and technology, the second one is focused on the science of economics and the third one on social sciences. ACC JOURNAL is a reviewed one. It is built upon the tradition of the “Scientific Treaties” published between 1995 and 2008. The journal is registered in international databases: INDEX COPERNICUS INTERNATIONAL, ERIH PLUS, ROAD Directory of Open Access Scholarly Resources and DOAJ Directory of Open Access Journals. Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.  Plagiarism Policy  The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
