A prerequisite for achieving high energy efficiency of water supply systems (understood as using less energy to perform the same task) is the appropriate selection of all elements and their rational use. Energy consumption in water supply systems (WSS) is closely connected with water demand. Especially in the case of oversized water supply systems for which consumers’ water demand is at least 50% less than previously planned and flow velocity in some parts of the system is below 0.01 m·s−1, this problem of excessive energy consumption can be observed. In the literature, it is difficult to find descriptions and methods of energy management for such a case. The purpose of this study was both an evaluation of the current demand of an oversized WSS and a preliminary technical analysis of the possibility for energy saving. Solutions are presented that resulted in improvements in energy management, thus increasing energy efficiency. The conducted analyses indicate the wide use of numerical, hydraulic models, among others, for the needs of the sustainable oversize water supply systems management in order to improve energy efficiency. Those simulations only give energy consumption results as a first step in the process of decision-making for the modernization process, in which investment costs should be taken into account as a second step. Thus, this paper emphasizes the crucial role of hydraulic models as a good analytical tool used in decision support systems (DSS), especially for large, oversized water supply systems.
Environmental awareness of managers and employees can be an important factor favouring the implementation of eco-innovation in enterprises. This article aims to identify the role of entrepreneur's ecological awareness in implementing the eco-innovation. In order to attain this purpose, the literature analysis in the field of environmental awareness and eco-innovation was conducted. The results of this analysis were the basis for the design and performance of the in-depth qualitative research based on a case study of a selected enterprise. As shown in the presented example, the high level of environmental awareness of entrepreneur translates into the company value systems and, additionally, it shapes the right attitude and pro-ecological preservation.
The article discusses the issue of smart specializations treated as a significant mechanism stimulating innovative development of water and wastewater economy. The article shows the links between the developing of smart specializations and the possibility of development innovative, research and development of the economy. The aim of the article is to present the meaning of the concept of smart specialization in the development of innovative water and wastewater economy at the national level and on the example of the Silesian Region. To achieve the goal, the theoretical assumptions of the concept of smart specialization were also presented. In particular, the article emphasizes the need for cooperation, establishing partnerships for the development of smart specializations that contribute to solving problems and increasing the competitiveness of EU countries and regions.
The issue discussed in this article concerns corporate social responsibility (CSR), which is playing an increasingly important role in the context of sustainable development of enterprises. The purpose of the current work was to assess the practices applied in the area of corporate social responsibility in water and sanitation companies, based on the opinions of employees and managers. The motivation for undertaking research on this topic resulted from the scarcity of scientific studies on the measurement of the corporate social responsibility concept in water and sanitization companies using a multidimensional approach based on the ISO 26000 standard. The study used methodological triangulation based on the use of qualitative and quantitative research methods to verify information from different sources. This approach allowed the authors to obtain the data more effectively and analyze the problem from numerous different perspectives. The study used an interview method that targeted water and sanitization utility staff. In-depth research was based on the case study method, which is particularly important when researching complex phenomena. For this purpose, surveys were carried out, the results of which indicate that corporate social responsibility of the surveyed enterprise is at a high level, and that there are statistically significant differences between individual dimensions of CSR. The results indicate that the surveyed company is oriented towards supporting activities in the area of corporate social responsibility, in accordance with the in the concept of sustainable development.
According to the Europe 2020 Strategy, the European's countries development should be based on three interrelated priorities: smart, sustainable and inclusive growth. All this priorities should be based on the increasing role of knowledge and innovation as the driving forces of future sustainable growth. The aim of this article is not to consider these categories separately, but their combination which allowed to present the possibilities and advantages for enterprises, resulting from the innovative activity directed at the sustainable development, using the sustainable management and sustainable production.
Kapitał innowacyjny ze względu na istotną rolę, jaką pełni w aspekcie procesów wdrażania innowacji w środowisku sieciowym, nabiera coraz większego znaczenia. Dziedzina innowacji jest szczególnie predestynowana do wykorzystywania podejścia sieciowego. W literaturze przedmiotu niewiele jest prac rozwijających koncepcje kapitału innowacyjnego w tym obszarze. Dotychczasowe badania kapitału innowacyjnego koncentrowały się przede wszystkim na procesach zachodzących na poziomie organizacji i regionu. Dlatego celem artykułu jest charakterystyka koncepcji kapitału innowacyjnego w perspektywie sieciowej wraz z ukazaniem wpływu kapitału innowacyjnego na procesy zarządzania innowacjami w sieciach. W oparciu o analizę literatury zaprezentowano w artykule także pojęcie kapitału innowacyjnego sieci. Sama koncepcja kapitału innowacyjnego sieci i odniesienie jej do procesów innowacji w oparciu o podejście sieciowe ma charakter wstępny, co inspiruje do uzupełnienia istniejącego stanu wiedzy w tym zakresie i podjęcia badań empirycznych.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
