In modern challenging environment, decision makers often need fast and effective tools to quickly model and optimize several decision alternatives and then compare them according to various preconditions or performance criteria. Specifically, efficient solid waste management requires responsible administration to implement detailed screening of needs and desired development directions, followed by decision on the implementing measures. Such process results with a number of various solid waste management scenarios, often with mutually conflicting objectives or expected results. These scenarios affect different range of population, relate to diverse problems, vary in costs levels and time needed to become effective.When selecting only one from various scenarios, different groups of decision-makers are involved. Decision-making has to take into account usually conflicting technological, economic, social and environmental objectives. Single-criterion decision-making based on available financial resources as a sole criterion does not respond to such requests.This paper demonstrates the reliability of use of multi-criteria decision making tool for the purpose of selecting the best municipal solid waste management scenario among six different alternatives. The multi-criteria decision making tool enables decision makers to make informed decisions and achieve optimal results. © 2015 Elsevier Ltd.

EU directives RESD (2001/77/EC) and WFD (2000/60/EC) can be considered as partially conflicting. Achieving a good qualitative and quantitative status of waters, what presumes " non-deterioration principle" of the existing ecological status in line with WFD, is conflicting with the construction of new hydropower plants that are promoting renewable energies, what is in line with RESD.Several projects have been developed in order to minimize conflicts between the two Directives, often providing a list of key criteria to be taken into consideration when deciding on the impact minimization of new ones or certification to existing plants. One example is CH2OICE, aiming at developing a technically and economically feasible certification procedure for hydropower generation facilities of high environmental standard.This paper aims to evaluate applicability of multicriteria decision aid to decision makers during the design process, decisions on site selection and plant technical and operational parameters, based on both economic and environmental criteria selected. © 2012 Elsevier Ltd.

The objective of this paper is to discuss the mapping methodology implemented in the selection of BAT candidates and to present the results of the mapping of B&H food and beverage sector, prepared as a baseline for the development of national reference documents on Best Available Techniques. The subsectors subject to analysis were: dairy, fish farming, fish processing, fruit and vegetable processing, meat processing, breweries, and slaughterhouses. The sector was mapped from several aspects, including socio-economic, legal, and environmental point of view. The socio-economic aspect focused on understanding the sector's structure and financial capabilities, pricing for water, energy, and solid waste consumption, as well as employee profiles, in order to better assess the sustainability of decisions taken. Legal mapping focused on relevant regulations, including policies from the following sectors: environment, water use and protection, food safety, agriculture, and veterinary, in order to determine legal requirements from an environmental protection aspect set in the various sector policies. Environmental performance indicators were calculated in order to assess present resource efficiencies and relevant environmental impacts. In addition, the mapping process also addressed the existing level of BAT implementation in the subsectors under consideration. The paper presents a rationale for methodology selection, offers a review of the mapping methodology used, discusses mapping results and provides conclusions in regards to that methodology used and discusses issues that need to be considered in the selection of BAT candidates. © 2010 Elsevier B.V.

The countries with transition economies are under pressure to increase entrepreneurial activities that will enable fast growth with minimum impact on natural resources. Despite specific challenges the economies in transition face, development of (sustainable) entrepreneurship has not been in focus of the academic research. This leaves some open questions such as those concerning the role and mode of operation of public policies, level of risk and its influence on entrepreneurship creativity, role of knowledge in diffusing entrepreneurial values and fostering aspirations, externalities created for the society and the connection between sustainability and entrepreneurship. This paper aims to introduce a discussion on sustainable entrepreneurship in countries with economies in transition. The research carried out included (i) review of literature and statistical data on entrepreneurial environment, (ii) structured interviews with representatives of government, civil society, business sector and academia to understand the society's perception of green entrepreneurship and (iii) analysis of case studies on green entrepreneurs. It can be concluded that entrepreneurs in economies in transition do not seem to be ready to respond to the challenges or to take any risks by investing in green business, but also that the government and educational institutions do not recognize their own role and fail to support the development of green entrepreneurship. For those "green oriented" businesses, the key sociological constructs are personal motivation and mission, locality, and a forward-thinking orientation in terms of sustainability. All businesses managed to achieve the economic, environmental and social value creation without any support from the government. © 2014 Elsevier Ltd. All rights reserved.

Climate change effects are most often presented with ongoing and expected temperature increase and sea level rise, but also stressed is the shift in rainfall patterns, often difficult to distinguish because there is much natural variability in precipitation. Statistical process control presents application of statistical methods and procedures for monitoring and control of the selected process. It aims to evaluate two potential sources of a process variation: natural (common) and assignable (special) causes. Statistical process control was recently used to evaluate climate change/variation, using previous referential period as a benchmark for addressing the present variations (e. g. in temperature or precipitation) as being triggered by natural or special causes. This means that either variation statistically should have been expected or the natural processes "capability" changed and variations are higher than one could expect. This paper analytically compares specific precipitation pattern changes in the three cities of Bosnia and Herzegovina with different annual participation. The comparison is based on the assessment of statistical behaviour of the precipitation data during the periods of 1961-1990 and after 1990. Such comparison allows preliminary conclusions on the studied geographical distribution of specific climate change/variation impacts. The presented results show that climate variations effect the precipitation patterns change, but do not confirm that they are as high as they could not be statistically expected, based on previous precipitation data.
