Abstract

Rural areas have great potential, which properly supported can signifi cantly accelerate the socio-economic development of the country. However, the resources and values of individual areas are spatially diversifi ed, which means the diversity of development challenges and the necessity to diversify the instruments of local development policy as well as the territorialisation of development policy. The need to deal with development issues in connection with the development of urban functional areas and, more broadly, node regions, remains unchanged for all types of rural areas, which means the necessity of joint planning of spatial development, implementation of common development strategies of the entire functional area and pursuit of common socio-economic goals. The endogenous theory of local development remains valid, but it must be based on resources that go beyond the administrative boundaries of a single municipality. The need for network local development planning applies in particularly to peripheral rural areas, since rural municipalities often do not have sufficient economic potential to stay competitive even on a local scale. Only in partnership with other municipalities, within the framework of nodal regions, they can implement more eff ective competitive strategies. Another aspect of the network cooperation is the need to involve non-public entities into local economy. Establishing partnerships for the implementation of development goals may increase the chances of achieving a favourable competitive position and implementation of effective development strategies.

Abstract

The development of electromobility is a challenge for the power system in both technical and economic-market terms. As of today, there are no analyses to determine the power necessary to supply the planned infrastructure and to estimate the incentives and economic benefits resulting from the modification of the settlement method. The document determining the legal regulations and the obligation to build vehicle charging stations for specific municipalities is the Act on Electromobility and Alternative Fuels. This act estimates that the development of electromobility, due to the specifics including not only individual vehicles, will take place in certain areas. The places which in the first stage will be dedicated to the potential implementation of the concept of electromobility will be municipalities covering large agglomerations. In addition, due to the local aspect, the development of electromobility may take place in the areas of energy clusters’ initiatives, which, using the policy of increasing energy awareness, are aimed at energy production from local renewable energy resources. The planned development of electromobility assumes a systematic increase in the number of electric cars caused by the introduction of support systems. The dynamization of this sector will cause an increase in the demand for electricity. Due to power system reasons, an important factor determining the level of energy consumption depending on the time of day may be an appropriate shape of the pricing for the charging service. Appropriate price list stimulation can affect the behavior of recipients, causing the charging of cars in the off-peak of electricity demand. The aim of the article is to characterize the scale of the phenomenon of electromobility in the context of the emergence of a charging points infrastructure along with the possibility of price-setting stimulation affecting the profile of energy demand. It is also important to consider the challenges and responsibilities of municipalities and energy clusters from the perspective of introducing electromobility.

Abstract

This publication presents an assessment of the economic efficiency of a hypothetical installation for the gasification of the municipal and industrial waste for the production of syngas used subsequently for the production of energy or chemical products. The first part of the work presents an example of a technological system for the energo-chemical processing of coal mud and municipal waste, based on the gasification process using a fluidized bed reactor. A hypothetical installation consists of two main blocks: a fuel preparation unit and a gasification unit. In the fuel preparation installation, reception operations take place, storage, and then grinding, mixing, drying and transporting fuel to the gasification unit. In the gasification installation, fuel gasification, oxygen production, cooling and purification of raw process gas and ash treatment are carried out. The following key assumptions regarding the gasification process, as well as the capital expenditures and operating costs related to the process, were estimated. Consequently, based on the method of discounted cash flows, the unit cost of generating energy contained in the synthesis gas (cost of energy, COE) was determined and the results were interpreted. In order to obtain an acceptable efficiency of the gasification process for waste fuels for the production of alternative fuel (process gas), it is necessary to supplement the mixture of waste coal and coal mud with the RDF. In this case, the unit cost of fuel measured by the PLN/GJ index is lower than in the case of hard coal and comparable with brown coal. The use of coal mud for the production of process gas in an economically efficient way is possible only in the case of changes in the legal system allowing for charging fees for the utilization of industrial waste – coal mud.

Abstract

Based on laboratory tests of selected properties of secondary waste (ashes and dusts) from municipal waste incineration plants, the possibility of recovering some properties of waste in the process of filling the post-mining voids in the salt mine was assessed. The furnace bottom ash and the waste from the flue gas treatment from one of the national incineration plants were examined. The grain curves of dry waste and the density of the prepared mixtures were characterized. Twelve variants of the compositions of ash-based mixtures with varying proportions of the individual components were considered, taking into account both fresh water and brine. For each variant of the composition, the amount of redundant liquid appeared as well as the time of solidifying of the mixture to a certain strength and the compressibility values obtained. Considering the possibility of transporting mixtures in mines by means of pipelines at relatively long distances, and allowing the filling of large salt chambers to be filled and evenly filled, flow parameters were determined. In addition, the permeability of solidified waste samples was investigated, showing the potential for reducing the strength of the waste mass due to the action of water or brine. The technical feasibility of eliminating redundant liquid in the binding process has been confirmed, which is particularly important in salt mines. Preliminary values for the amount of binder (5%÷10%) to be added to the mixtures to obtain the specified strength properties of the artificially formed mass at Rc = 0.5 MPa. Attention was paid to the important practical aspect resulting from the rapid increase of this type of waste in the comming years in Poland and at the same time vast potential for their use in salt mining, where we have a huge capacity of salt chambers available.

Abstract

Local development, based on the use of endogenous potentials, requires the cooperation of muni-cipalities in urban functional areas (agglomerations). However, conducting joint activities in the area of building and running local development policy is a serious challenge. On the one hand, there is a shortage of experience in this area (not counting the short period of functio-ning municipal unions in the years 1920-1939 and intentional inter-communal relations after 1990). In addition, there are still no legal solutions needed (in addition to the act passed in 2017 for the metropolis of Silesia and Zagłębie). In recent years, however, projects of integra-ted territorial investments and other project partnerships have been implemented under the European Union and the Norwegian Financial Mechanism Programs, which result in prac-tical conclusions and legislative recommendations. The most important of them concern the introduction of a new form of partner cooperation and the adoption of a new urban code. Their quick implementation will enable more eff ective cooperation for development.

Abstract

The Cracow districts have the status of auxiliary self-governing units within this city and, generally should be communities of residents living in particular parts of the city, close to them, in which they implement their daily practices. In theer article, the authors, by examining the sense of belonging to the district, undertook to identify its perception by residents and relations between the residents and their auxiliary units, on the example of two such districts this of VIII Dębniki and X Swoszowice. Attitudes of their residents towards self-governing districts were identified on the basis of 1141 questionnaires, obtaining during surveys conducted in 2017. The authors have found relatively weak relations of residents with their auxiliary units, as evidenced by small involvement in initiatives taken for the benefit of this districts. The analysis, however, showed also considerable differences in the detailed assessment of the attitudes of residents at the level of their division according to their age groups, period of the residence, as well as to the type of housing a single-family, multi-family or mixed ones.

Abstract

There is a very high interest in international literature about the governance of common goods related to a redefinition of representative democracy. Scholars like Sheila Foster and Christian Iaione have proposed new models of governance enhancing the preservation and management of the commons in order to overcome problems and contradictions of complex contemporary cities, such as social exclusion and land privatisation. The aim of this paper is to verify, through a recognition of administrative documents, if in the example of Rome, the political actors, the municipal government, and the civil society, could be able to take part in a collaborative governance inspired reform. To answer this question, the relationship between the policy making process, the economic production model and the normative claims arising from social groups will be investigated. What is emerging is a difficulty of the administration in implementing collaborative principles. This is reflected in the issuance of discordant administrative measures, stemming from problems in relaying to civil society and active citizens the role that these principles assign. The reasons for this mismatching might be identified in the distinctive urban regime of Rome and the political and economic set that fosters social exclusion and does not consider the positive effects and the value of collaborative-oriented policy, enhancing sharing economy and social cohesion. The constant recall in the political discourse of concepts such as common goods, citizen’s participation and collaboration values takes the characteristics of a discursive resource, a ‘common washing’, which institutions and politics seem to re-propose and consolidate the traditional mode of public action, though apparently declaring its inadequacy and ineffectiveness.

Abstract

The EU member states have implemented excise duties on fuel and electricity according to the EU Energy Tax Directive. The purpose of these measures is to motivate a reduction in energy consumption by internalizing external costs of energy. The taxes on energy have success in inciting energy savings. Simultaneously, the price levels of energy in the EU member states have increased to levels significantly higher compared to other countries in the region and the world. The price increase is the result of a cumulative effect of excise duties and other taxes and mechanisms including feed-in tariffs and quota policies. While the Energy Tax Directive gives the member states a level of freedom in setting the exact duty rates, the minimal rates enforced on all member states are relatively high. The policy intends to limit competition between the states on low energy prices and arbitrage trading between countries. We examine the purchasing power for energy products relative to the per capita GDP for a wide set of countries countries within the EU and in the rest of the world. We can identify several groups or clusters of countries based on their GDP per capita and energy prices. The new member states of the EU face a unique combination of low or moderate GDP per capita and very high energy prices. Their relative purchasing power for energy is degraded to levels comparable or lower than the purchasing power in developing countries with significantly lower GDP per capita and underdeveloped energy infrastructure. The calibration of energy taxation in the EU at high price levels suitable for Western European economies with high per capita GDP is leading to strong negative social effects and increasing poverty in Eastern European member states. The current implementation of these policies does not recognize to a sufficient extent income levels, regional social inequalities, and the low price elasticity of demand for energy.

Abstract

In this article the author attempts to define the specificity of the tools for development planning at the local level in the context of: institutional resources of community (gmina) (and means of strengthening them), models of public management as well as the specifics of the Polish public administration system and its ensuing dysfunctions. These dysfunctions rely mainly on a limited awareness of the need to create mechanisms of coordination for: socio-economics, spatial and financial planning. These factors contribute to a decrease in the effectiveness of measures for the development of communities. Socio-economic planning answers the question: WHAT we want to do in the community; spatial planning: WHERE we would like to carry out certain activities, and financial planning: HOW MUCH it will cost and where the financial sources are. We can see the theoretical causal links between the areas of development planning, therefore, the main purpose of this article is to offer conceptual framework and a relevant case study of Kraków serving as its validation attempt.

Abstract

The new legislative provisions, regulating the trade in solid fuels in our country, draw attention to the need to develop and improve methods and methods of managing hard coal sludge. The aim of the work was to show whether filtration parameters (mainly the permeability coefficient) of hard coal sludge are sufficient for construction of insulating layers in landfills at the stage of their closing and what is the demand for material in the case of such a procedure. The analysis was carried out for landfills for municipal waste in the Opolskie, Śląskie and Małopolskie provinces. For hard coal sludge, the permeability coefficient values are in the range of 10–8–10–11 m/s, with the average value of 3.16 × 10–9 m/s. It can be concluded that this material generally meets the criteria of tightness for horizontal and often vertical flows. When compaction, increasing load or mixing with fly ash from hard coal combustion and clays, the achieved permeability coefficient often lowers its values. Based on the analysis, it can be assumed that hard coal sludge can be used to build mineral insulating barriers. At the end of 2016, 50 municipal landfills were open in the Opolskie, Śląskie and Małopolskie Provinces. Only 36 of them have obtained the status of a regional installation, close to 1/3 of the municipal landfill are within the Major Groundwater Basin (MGB) range. The remaining storage sites will be designated for closure. Assuming the necessity to close all currently active municipal waste landfills, the demand for hard coal sludge amounts to a total of 1,779,000 m3 which, given the assumptions, gives a mass of 2,704,080 Mg. The total amount of hard coal sludge production is very high in Poland. Only two basic mining groups annually produce a total of about 1,500,000 Mg of coal sludge. The construction of insulating layers in landfills of inert, hazardous and non-hazardous and inert wastes is an interesting solution. Such an application is prospective, but it will not solve the problem related to the production and management of this waste material as a whole. It is important to look for further solutions.
