Efficiency is the result of the actions taken, described by the relation of the results obtained to the expenditures incurred. The main assumption of the described research project was to develop a significantly improved façade washing machine capable of working in adverse weather conditions, i.e. wind conditions. Among the many technological challenges, an important for the effectiveness of façade washing machines is the ability to efficiently move around the façade, determining the washing efficiency while maintaining constant contact of the machine with the façade and at the same time overcoming and avoiding obstacles, especially in changing weather conditions. Most of the solutions used will work in specific conditions. The research allowed to select a structural solution that allows to modify or develop the washing machine in such a way as to ensure the correct washing path of the façade regardless of weather conditions up to a wind speed of 40 km / h.

Efektywność jest wynikiem podjętych działań, opisanym relacją uzyskanych wyników do poniesionych nakładów. Głównym założeniem opisywanego projektu badawczego było opracowanie znacząco ulepszonej myjki fasadowej zdolnej do pracy W niekorzystnych warunkach atmosferycznych, tj. wietrznych. Wśród wielu wyzwań technologicznych ważnym dla skuteczności myjek fasadowych jest możliwość sprawnego poruszania się po elewacji, określania efektywności prania przy zachowaniu stałego kontaktu maszyny z elewacją przy jednoczesnym pokonywaniu i unikaniu przeszkód, szczególnie w zmiennych warunkach atmosferycznych. Większość zastosowanych rozwiązań sprawdzi się w określonych warunkach. Badania pozwoliły dobrać rozwiązanie konstrukcyjne pozwalające na modyfikację lub rozbudowę pralki w taki sposéb, aby zapewnić prawidłową ścieżkę mycia elewacji niezależnie od warunków atmosferycznych do prędkości wiatru 40 km/h.

Purpose: The aim of the article is to analyze the implementation of the Industry 4.0 technologies to improve eco-efficiency of manufacturing processes from the perspective of the development of innovative IT technologies in the circular economy. Design/methodology/approach: The research methods used in the article were desk research analysis of available source data on the functioning of Industry 4.0 technologies. Additionally, the author bases on the institutional and legal method. Analysis of selected documents and existing studies have allowed to obtain answers to the research questions and to describe the eco-efficiency of manufacturing processes. Findings: The Industry 4.0 technologies in the circular economy can contribute to improve the eco-efficiency of manufacturing processes. However, there are still some difficulties in creating the fully efficient processes in the circular economy. Research limitations/implications: The main limitation in carrying out the research is the difficult access to data about the quantity and quality of the eco-efficiency of manufacturing processes improving by the Industry 4.0 technologies. Practical implications: The results of analysis and the conclusions in this article can be used by managers of the different types of companies involved in the circular economy. The research impact upon the enterprise concentrating on the raising awareness of the benefits of using wide range of the Industry 4.0 technologies for improving the eco-efficiency of manufacturing processes. Originality/value: This article describes the benefits that can be obtained from the implementation of the Industry 4.0 technologies in the circular economy. The research issues related to development of the circular economy constitute a new area of research. The newly developed focus on improving eco-efficiency of the manufacturing processes by using the innovative IT technologies in the circular economy. The eco-efficiency of the manufacturing processes in the circular economy, examined from the point of view of the use of Industry 4.0 technologies, is an innovative research approach.
