The Living Lab is an innovative and effective approach to restoring soil health on unproductive land. Through collaboration between different researchers and the use of adaptable and sustainable solutions, this method can transform degraded land into valuable resources, contributing to agricultural sustainability and the development of local commun...

The present paper is in fact a continuation of a research effort started approx. 16 years ago, and whose main purpose is to follow the process of transformation of rocks from coal mining waste dumps into a fertile soil. Thus, during 2022, a new sampling campaign was carried out from the Petrila waste dump, which was later subjected to laboratory te...

Global warming and climate changes, as well as the contribution of fossil fuel to the accentuation of these phenomena are realities almost unanimously accepted. Therefore, the reduction of the coal ratio in the energy mix and its replacement with forms of energy without emissions is being discussed more and more frequently. Nevertheless, it is impo...

The paper is motivated by the need to provide relevant synthetic indicators, on the basis of which decision makers can evaluate and compare, the extent to which the proposed projects fall within the goals of sustainable development - economic efficiency, environmental responsibility, social solidarity, circular economy, production and responsible c...

The energy perspective of the near future relies on the use of natural gas and renewable energy resources and for the distant future hydrogen energy is shaping up. In order to provide the correct information necessary for a high-performance option in the case of the availability of photovoltaic panels or cogeneration generators, this paper addresse...

The paper deals with an energetic, economic and ecologic comparative analysis regarding the installations for the incineration of wood waste in order to ensure the heat for a centralised system used for the supply of thermal energy. The results obtained have highlighted the advantages and disadvantages for each type of fuel used. An aggregate indic...

Sustainable development represents an optimistic scenario for the evolution of contemporary civilization. The object of this paper is to define certain evaluation criteria regarding the performances of water discharge networks from mining works, and propose a method for aggregating the specific indicators for monetary costs, energetic costs, and en...

This paper addresses the sensitive subject of residents in marginalized urban areas and proposes solutions in order to improve life quality parameters by accessing multidisciplinary networks of knowledge and information. In the context of contemporary technologies, conclusions resulting from applied practices in strictly contextualized situation be...

The main objective of the paper is to highlight the evolution of the energetic and environmental performances of a condensing and cogeneration 150 MW power plant for different loading levels. The values obtained from the creation of the real hourly thermal-energetic balance were graphically processed highlighting therefore the comparative evolution...

The paper deals with a case study for carried out in order to justify the installation of a gas cogeneration system fitted with an internal combustion engine, system used to supply electricity and heat to the users of an energy user which exceeds 1000 toe/year. 2 scenarios were therefore compared based on the energetic analysis: -the actual scenari...

This work presents a research of methodology in occupational stress analyse in the educational field, as a part of a larger study. The objectives of the work are in finding accents in existence of significant relations between stressors and effects, meaning the differences between the indicators of occupational stress to teaching staff in primary a...

Considering the composition of wastewater sludge, a comparative analysis of 3 energetic usage solutions of the biogas is carried out. The energetic and economic performances are brought forward as well as the environmental impact through the use of biogas for a hot water generator and for a heat recovery diesel electricity generator.

The paper represents the application of a multicriterial analysis for establishing the decisional priorities in the field of impacts generated by polluting emissions from large burning installations. The analytic hierarchy process (AHP) method was used in order to express quantitatively how the environmental protection and sustainable development o...

The problem the paper deals with is the determination of ground heat distribution on different distances inside a cylindrical mine work. Both interior radius and the exterior radii of the cylinder are known. The use of the range of temperatures is useful for the calculation of the heat exchange rock - air. Results dissemination allow the developmen...

This paper aims to explore the interactions, influences, operationalizing and quantification of a Regional Dynamic System (RDS) with the help of new methods appropriate to the study of complex systems and their development for solving difficult problems of sustainable development. The scope of the research is to provide a recent development model o...
