Opis:
According to the amendment to the Act on maintaining cleanliness and order in communes, a stationary a municipal solid waste collection point (MSWCP) must be established in each Polish commune or commune union and situated close to the commune center. This point (MSWCP) should exist in the commune (or commune union), which are covered in 100% by protected zone. These objects are a new element in managing of the stream of municipal solid waste in Poland, known in the European countries as “household waste recycling centers” (HWRC). The aim of the work was developing the procedure with the use of tools enabling setting potential locations for MSWCPs in protected areas. The developed method was applied (for verification of the assumptions) in the process of seeking optimal locations for MSWCPs in the communes located in the Świętokrzyski National Park (ŚNP) protection zone. The paper presents the methodology for setting locations for municipal solid waste collection points. A method was developed using the Analytic Hierarchy Process (AHP) and Geographical Information System (GIS). It was possible to designate between 98 and 191 potential locations of MSWCPs in the communes situated in the ŚNP protection zone. The assumed criterion of maximum distance from the commune center eliminated 85% of locations. Optimal locations for MSWCPs in each commune were determined using AHP method. The main results of this research was to establish of MSWCP location for every commune in analyzed protected zone, based on the proposed methodology. The method presented in the paper may be a tool for the environment impact assessment of these investments.

Opis:
The work examines the role of innovative solutions in order to make more efficient use of waste and the reduction of their storage. Such solutions are necessary in the transformation process of linear economy to circular model. In the new model, the role of waste is being changed. Waste has not yet been treated as a by-product of economic activity but as a valuable resource that can be reused in the production process. There were also analysed how extent is the development of innovativeness in Poland in comparison to other European Union Member Countries. There is also analysed the direction of changes in the waste management field, especially in the structure of municipal waste. Another aim is to examine the examples of the Polish enterprises acting in waste management sector and the kind of innovative methods they use. In the article there were also presented supportive tools for implementing innovations in enterprises, with a focus on the waste management. They include among others: National Smart Specialisations and Regional Smart Specialisations.

Opis:
W pracy oceniano jakość świadczonych usług w zakresie odbioru odpadów komunalnych na terenie gminy miejsko-wiejskiej Wadowice. Badania realizowano w latach 2013-2015. Jako narzędzie badawcze przyjęto formę ankiety mającej postać kwestionariusza. Zastosowano metodę mierzenia jakości usług SERVQUAL (service quality), określającą rozbieżności między oczekiwaniami konsumenta a postrzeganiem produktu. Założeniem tej metody jest wyrażanie jakości usług jako różnicy pomiędzy usługą oczekiwaną przez klienta (jakość oczekiwana) a usługą otrzymaną (jakość nabywana). Wynik analizy pozwolił na ocenę jakość świadczonych usług w zakresie odbioru odpadów w badanej gminie oraz wytypowanie przedsiębiorstwa preferowanego przez mieszkańców gminy Wadowice w aspekcie odbioru odpadów. Mieszkańcy gminy Wadowice wykazują wyższe oczekiwania w zakresie świadczonej usługi odbioru odpadów komunalnych z ich posesji. Dużą wagę przypisują rzetelności przedsiębiorstwa świadczącego tą usługę.
The work assessed the quality of services in the field of collection of waste in the urban-rural commune of Wadowice. The research was carried out in 2013-2015. The form of a questionnaire survey was adopted as a research tool. The method used to measure the quality of SERVQUAL services (service quality) defines the discrepancy between the consumer’s expectations and the perception of the product. The assumption of this method is to express the quality of services as the difference between the service expected by the client (expected quality) and the service received (purchased quality). The result of the analysis allowed for the assessment of the quality of services provided in the field of collection of waste in the studied commune and the selection of the preferred enterprise by the residents of the Wadowice commune in the aspect of waste collection. Residents of the Wadowice commune show higher expectations as regards the service of receiving municipal waste from their property. They attach great importance to the reliability of the company providing this service.

Opis:
Generated wastes require space and financial outlays on their proper storage and processing, whereas the lack of means usually leads to depositing wastes in places not meant for this purpose. Illegal dumping sites still emerge, despite introducing in Poland the obligatory (common) fee for collection and management of wastes and the obligatory establishing the Selective Waste Collection Points in each district. The aim of the work was conducting a detailed inventory of illegal dumping sites in the area of Olsztyn district (situated in the Silesia province, on the Krakow-Częstochowa Upland) and indicting the morphological composition of the wastes deposited in these places. The paper presents a detailed analysis of the morphological composition of illegal landfill sites situated in the analyzed district. The investigations located 28 illegal dumping sites, despite the fact that a Selective Municipal Waste Collection Point operates in the district area. The analysis of location, area, mass and composition of the wastes was conducted for each illegal landfill, according to the methodology developed for this purpose. Over a half of the illegal dumping sites was situated in the forest and on 4 of them the estimated mass of dumped waste exceeded 1Mg. Debris constitutes the highest proportion (21.8%) of the waste morphological composition. Recyclable wastes, i.e. glass, plastics, paper and cardboard, used electronic and electric equipment dominated in the morphological composition of wastes on small landfills, situated close to buildings (less than 250m) and had the smallest area (below 1m2 ). The share of debris and construction wastes was growing with increasing landfill area.

Opis:
Mixed municipal solid waste collected from the area of each Polish district (commune) is transferred to Regional Installations for Municipal Solid Waste Treatment. They comprise one or more of the following facilities: installations for mechanical-biological waste treatment (MBT), installations for thermal treatment of municipal solid waste, green waste composting plants and landfill sites. MBT installations have been currently the dominant technology of mixed municipal solid waste treatment in Poland. In these installations mixed waste is subjected to mechanical processes (including: crushing, separation, screening and classification) resulting in the production of the undersize fraction with usual grain size below 80mm and the oversize fraction with grain size over 80mm. Because of the necessity of stabilization and hygenization of the undersize fraction prior to landfilling, it is subjected to the process of biological treatment, e.g. biostabilization. The main aim of the research was to analyze the temperature changes during the biostabilization of the undersized fraction in thermally insulated BKB100 laboratory bioreactor. The research covered a 14-day period of the intensive phase. The analyses were performed in 6 replications. 40.1±2.2kg of waste with density of 519.2±27.5kgˑm-3 and the biodegradable fraction content of 41.9±1.9% was placed in the reactor. The temperature of waste inside the reactor was measured by 9 Pt 1000 temperature sensors. The air for the process was constantly supplied from the outside of the reactor. Flow of the supplied air with temperature of 18.3±3.1°C was regulated depending on the average indication of all temperature sensors. Results of the temperature measurements were averaged and showed using Golden Software Surfer 7. As a result of the conducted research it was found that changes in the temperature inside the bioreactor occurred uniformly throughout its full volume. The time of reaching the temperature of 45°C (the beginning of thermophilic phase) was 25.6±4.0 hours (21 hours at the earliest). During the first period the temperature in the reactor was increasing most intensively in the lower parts of the layer, in the central part of the layer the temperature reached 45°C after 34 hours at the earliest, whereas on average it took 47.7±9.9 hours. The average maximum process temperature was 64.8±3.5°C.

Opis:
Municipal Solid Waste (MSW) is the mixture of many waste types, including organic waste (garden and park waste, food and kitchen waste, paper and cardboard etc.). Such waste creates a living environment for various microorganism species, many of which are known as pathogenic. The presence of microorganisms in favorable conditions (pH, organic matter content, carbon content, moisture, appropriate granulation) leads to decomposing of organic matter, which is accompanied by an increase in temperature. Microorganisms in waste pose a serious risk for staff operating at waste treatment plants. Moreover, heat released by their activity may cause a fire in waste storage facilities. Therefore, it is necessary to search for methods of waste stabilization and hygienization. The most commonly applied technology for waste stabilization is its processing in Mechanical Biological Treatment (MBT) plants. Such treatment is capital – and timeconsuming, however. Waste liming can become an alternative method for stabilization and hygienization of waste. Lime addition is one of the oldest method known by humans for hygienization of certain waste materials, such as animal waste. Currently, liming is applied in sewage sludge treatment as one of the initial operations and is necessary for further sludge management processes. The aim of the research was to valuate temperature changes during mixed MSW hygienization process with CaO addition in the amount of several percent by using a thermographic camera. The reaction of CaO with waste is short and lasts no longer than 20 minutes. The maximal temperatures were reached after 65-124 seconds from the time of CaO addition. The most dynamic increase in temperature were observed up to approx. 120th second of the process, with the rate dependent on the initial moisture of the material. The observed pH values indicate that the maximal dose of CaO additive should not exceed 3%. Such a dose is sufficient for waste to reach pH 12, which, according to literature, guarantees the deactivation of microorganisms.

Opis:
One of the most serious problems of waste management in Czech Republic is the useful treatment of biodegradable municipal waste because EU Council Directive 1999/31/EC requires of member states to limit the amount of biodegradable waste deposited into landfill. Composting of biodegradable municipal waste can be a solution of this problem but there are many operational and economic problems. This article describes advantages and problems of bio-waste composting in rural conditions (of Czech Republic) at all parts of composting process, i.e. from bio-waste sorting and collection through bio-waste composting to utilization and sale of compost. Bio-waste composting in countryside brings many benefits. The waste is treated at the place of origin and it is possible to get the organic mass of compost back to the field with minimal transport distances. Decentralized waste treatment brings jobs to regions of a small rate of employment. It is necessary to solve many problems related to the process of composting. Quality of input raw material is the first of them. It was found that the amount of undesirable impurities in separately collected biodegradable municipal waste depends on the type of building density and the settlement size. By the measurement of 200 kg samples of sorted bio-waste it was showed that purity of waste sorting is much better in small villages than in rather big cities. Right size of composting plant is another question to discussion. A lot of small composting plants built for several villages allow waste treatment in the place of origin but just a big composting plant is rich enough to have adequate machine equipment. Of course, in this case transport distances are long. Compost selling is connected with other problems. Farmers usually do not want even high-quality compost because of the costs of compost application to the field (although missing of organic mass in the soil). Lots of low-quality compost is used as a reclaim material.

The objective of this paper is to zoom in on the system of separated waste collection in Czech Republic (CR). The system of packing waste collection is described. The analysis of collection of base commodities of communal waste (paper, plastics and glass) in chosen regions has been carried out. St edo eský region has been chosen because of the number of its inhabitants and as well because of its location in the middle part of CR and because it neighbours with the Czech capital city, Prague. Region Vyso ina shows average values in base commodities collection. The results of the chosen regions are being compared to the present status of separation of these wastes in CR which is counted by packing company EKO-KOM. The company caries out back withdrawal and usage of wastes of mentioned packages.

Opis:
A new act on maintaining the cleanliness and order in communes of 1 July, 2011, will become effective in Poland on 1 January, 2012. The act will come fully into force on 1 July, 2013. According to this act regulations, commune self-governments take over the obligations of the property owners concerning waste management, moreover, they become responsible for construction and maintenance of the infrastructure supporting recycling and waste disposal processes. The self-governments were granted a 1.5 year transition period to implement the act regulations.The introduced changes are an adjustment of Polish regulation to the European law. Only in Poland and Hungary local self-governments have not yet been responsible for management of waste generated in their areas.The article presents an analysis of the basic changes introduced by the act to the Polish system of municipal waste management. Presented are also the estimates of the mass of wastes collected on the territory of Poland with particular regard to the Małopolskie voivodeship. Calculations and forecasts were made on the basis of information collected by the Main Statistical Office (GUS) and commune offices, where systems similar to the one introduced by the act have been operating for several years. The act assumes that all citizens of Poland will be covered by a system of waste collection, but will also have to pay so called "garbage tax", which should translate into increased amount of collected wastes, especially in these communes where wastes collection system was faulty. In Małopolskie only in 30 communes the 100% of inhabitants have signed contracts for garbage disposal. In the communes where the modern municipal waste management system has been operating, the increase in the mass of collected wastes (for the first three years of system operation) ranged between 31% and 94% in relation to the mass collected in the year preceding the introduction of the new system, although over 90% of local inhabitants were covered by the previous system. As results from the analyses, after introducing the new act the amount of wastes collected in the Małopolskie voivodeship may increase from the level of 765,000 Mg (2010) to over 1.1 M Mg (1.4 M Mg according to less optimistic forecasts), assuming that all generated wastes will be collected (the same amount as in 2010). In some of the Małopolskie communes the estimated increase in collected municipal wastes may reach over 500%.

Opis:
Successive closing down of filled-up large municipal landfill sites or those which no longer fulfil the legal regulations, compel local governments and enterprises dealing with waste disposal, to undertake activities aimed at designing and construction of new waste management plants. One of these is a municipal solid waste sorting plant where the waste stream is divided into sub-screen and screen fraction. The screen fraction after removing ferrous and non-ferrous metals, glass and other impurities and crushing to an appropriate particle size constitutes an alternative fuel. The most frequently alternative fuel is manufactured from selectively collected plastics, rubber, textiles and waste paper. Alternative fuel is also manufactured from municipal solid waste in mechanical waste treatment plants. Municipal solid waste is characterized by a non-uniform morphological composition (depending on many factors), which may result in variable parameters of the manufactured fuel. If the waste fuel manufactured in this way and supplied to cement plants does not reach certain quality standards, its price is low, or the product is not accepted for energy recovery. The work presents results of analyses of selected properties of alternative fuels generated from solid municipal waste stream with regard to the type of communes from which the waste originated (urban commune area or rural communes). Statistical analysis was conducted using Bayesian Networks. As it results from the investigations, alternative fuel manufactured from municipal solid waste is characterized by high values of variation coefficient for such parameters as: ash content, moisture and calorific value. The content of carbon, sulphur and incineration heat revealed low values of variance coefficient. The analyses have demonstrated that technological values of alternative fuel do not depend on the administrative type of the communes where the waste used for their production was collected.

Opis:
The presence of municipal solid waste landfills is an inevitable spatial phenomenon that expresses the planning properties of the process of land use, economic development and the relationship to the environment. The process of land use is continuous, in which a period of planning, development and management of its operation is followed by a period of decline in the performance of (aging) and the fall of the land. Closing the landfill and reclamation results in the appearance of problem areas, i.e. of degraded areas both on the site and in the area of its influence. The paper presents the concept of development of a closed municipal solid waste landfill in the village Woźbin in the commune Cegłów and adjacent areas. According to the ‘Project of closure and reclamation of municipal solid waste landfill in the village Woźbin, in the commune Cegłów’ after the operation of the landfill as well as the technical and biological reclamation, can be implemented forest restoration direction. The concept of developing the reclaimed municipal landfill and the adjacent land is assumed to introduce the planned forest reclamation and complement the recreational function which will increase the attractiveness of the area and will enable its use in a more economical way aimed at integrating the municipal solid waste site with its surroundings.

Opis:
Among solid wastes one may distinguish mixed wastes, segregated wastes (collected selectively) and biodegradable wastes originating from open-air markets, green areas or cemeteries. Mixed wastes have constituted the largest proportion in the stream of municipal solid waste (MSW), both before and after the changes in waste management system in Poland introduced on 1 July 2013. The other group, regarding the collected wastes volume, is so-called segregation. It has been forecasted that in the nearest future the amount of segregated wastes will be successively growing. The article presents the analysis of selectively collected wastes (paper, plastics, glass and metal) indicators from lower administrative units of Liszki and Mogilany communities. The degree of segregated wastes accumulation efficiency was assessed on the basis of conducted computation. The communities selected for the analysis are suburban municipalities, situated in the area of Krakow agglomeration in the immediate vicinity of the main city of the Malopolskie voivodeship. The main aim of the work was an assessment of selective accumulation of municipal solid wastes in suburban communities. Values of quantitative indices, characterizing mixed and segregated municipal solid waste generated by the inhabitants of individual lower administrative units of the studied communities were subjected to a detailed analysis. The data assumed for the investigations cover the period from July 2012 to June 2013. As results from conducted analyses actual indices of wastes accumulation differ from the indices determined on the basis of statistical data and the data stated in the Waste Management Plans, which may evidence a high ecological awareness of the analysed areas inhabitants. The efficiency of selective waste accumulation in the analysed communities was on a similar level and exceeded 20%, i.e. was twice higher than the average for Poland.

Opis:
The article presents the results of a research on the processing of undersize fraction, extracted from a stream of mixed municipal solid waste (MSW), into alternative fuel, in the process of bio-drying. The analysis was conducted with the use of an innovative EWA (Ecological Waste Apparatus) bioreactor adapted to carrying out aerobic treatment of waste in such processes as: composting, aerobic digestion/stabilization and bio-drying of waste. EWA bioreactors have been designed and manufactured by AGRO-EKO spol. s r.o. from the Czech Republic. The subject matter of the analysis was undersize fraction, with particle dimensions ranging from 0 to 50 mm, manufactured in the process of sorting (mechanical processing) of MSW. The main aim of the research was to assess suitability of the use of EWA bioreactor in the process of alternative fuel production from undersize fraction developed from municipal waste (in the process of accelerated bio-drying). Samples were collected between 2011 and 2012. The undersize fraction and the produced alternative fuel were analysed by AGRO-EKO spol. s r.o. and at the University of Agriculture in Krakow, in accordance with the standards for wastes and solid fuels. It has been concluded that undersize fraction produced from mixed municipal waste might be the energy source for cement plants or commercial power plants. As a result of a 66-hour accelerated process of bio-drying of undersize fraction (the standard time being ca. 7 days), the waste-mass has been lowered by reducing water content (moisture) in undersize fraction by ca. 15 % while increasing its calorific value and the C:N ratio. The process resulted in the increase of non-combustible and non-biodegradable elements. The high C:N ratio and the amount of organic substances at the level of 78 % should enable further aerobic and anaerobic stabilization preceded by substance moisturizing.

W artykule przedstawiono analizę struktury kosztów transportu odpadów komunalnych gromadzonych selektywnie, odbieranych z terenu miasta Krakowa oraz 13 gmin podmiejskich. Do analiz wybrano 4 pojazdy odbierające tzw. segregację z gospodarstw domowych (gromadzoną w różnokolorowych workach). Pojazdy te posiadają zbliżoną charakterystykę pracy. Wszystkie należą do prywatnego przedsiębiorstwa zajmują- cego się zbieraniem i transportem odpadów komunalnych, budowlanych i opakowaniowych. W wyniku przeprowadzonej analizy stwierdzono, iż w strukturze kosztów transportu odpadów segregowanych dla wszystkich analizowanych pojazdów, dominują koszty zużycia paliwa, koszty wynagrodzenia oraz zakupu worków, stanowiące odpowiednio 29,5%, 26,7% i 18,0%. Pozostałe koszty oraz zysk przedsiębiorstwa stanowią 25,8% całkowitych kosztów zbierania i transportu odpadów segregowanych. Koszt transportu 1 Mg odpadów gromadzonych selektywnie wynosi średnio 243,3 zł. Mg-1. Koszt ten jest wyższy o około 60 zł. Mg-1 w stosunku do kosztów transportu zmieszanych odpadów komunalnych. Średnie zu- życie paliwa (ON) w przeliczeniu na 1 Mg segregowanych odpadów komunalnych wynosi około 13,2 dm3·Mg-1 i jest ono wyższe niż zużycie paliwa przez śmieciarki (transport zmieszanych odpadów komunalnych) o 1,1 dm3·Mg-1. W wyniku badań stwierdzono, iż istnieje statystycznie istotna zależność pomiędzy zużyciem paliwa (dm3·Mg-1), a udziałem kursów realizowanych na terenach wiejskich (R = - 0,83).
This paper reports the analysis of transport costs for segregated municipal solid waste (MSW) collected from the Krakow city and the 13 municipalities bordering the main town of Małopolska Region. There were 4 selected vehicles (garbage trucks) analyzed (collected segregated waste from households) These vehicles have a similar work characteristics. These vehicles belong to private enterprise dealing with the waste transport. The largest share in the structure of the waste transport and collection have fuel costs (29.5%), salaries (26.7%) and cost of bags purchase (18.0%). Other costs and enterprises profit represent 25.8% of the total transport costs. The average unit cost of segregated waste transport and collection is 243.3 zł. Mg-1 and is higher by 60 zł. Mg-1 in relation to the cost of mixed waste transport. Average fuel consumption (Diesel) per 1 Mg of segregated waste is about 13.2dm3·Mg-1 and it is higher than for mixed waste by an average of 1.1 dm3·Mg-1. Furthermore there is a statistically significant dependence between the unit costs of waste transport (dm3·Mg-1) and participation of courses realized at the rural areas (R = - 0.83).

Opis:
Obowiązkiem każdej gminy w Polsce jest utworzenie stacjonarnego punktu lub punktów selektywnego zbierania odpadów komunalnych (PSZOK). Obiekty te stanowią nowy element zarządzania strumieniem stałych odpadów komunalnych, znany w krajach europejskich pod nazwą - „household waste recycling center”. Brak tego typu infrastruktury gospodarki odpadami komunalnymi na terenie wielu polskich gmin lub istnienie PSZOK-ów w wersji mobilnej, przyczynia się do powstawania dzikich wysypisk, a ponadto nie umożliwia zwiększania poziomów recyklingu i ponownego użycia niektórych grup odpadów. W pracy dokonano porównawczej oceny oddziaływania na środowisko pięciu istniejących PSZOK-ów na terenie jednego z powiatów województwa świętokrzyskiego. Ocenie poddano lokalizację, funkcjonowanie i wyposażenie tych obiektów. W analizie oddziaływania na środowisko została wykorzystana metoda RIAM (Rapid Impact Assessment Matrix). Spośród przeanalizowanych PSZOK-ów dwa otrzymały ocenę pozytywną, natomiast 3 obiekty powinny zostać zlikwidowane lub całkowicie zmodernizowane.
The duty of each municipality in Poland is to set up a stationary Municipal Solid Waste Collection Points (MSWCP). These facilities are a new element of municipal solid waste management system, known in European countries as: „household waste recycling center”. The lack of this type of municipal solid waste management infrastructure in many Polish communes or the existence of MSWCPs in the mobile version contributes to the emergence of wild dumps, and also don’t allow the increase of the levels of recycling and reuse of some groups of waste. The environmental impact assessment of five existing MSWCPs in one of the poviats of the Świętokrzyskie Voivodeship was compared in article. The location, functioning and equipment of these facilities were assessed. The RIAM (Rapid Impact Assessment Matrix) method was used for the environmental impact analysis. From among the analyzed MSWCPs, two received a positive assessment, while 3 objects should be close down or completely modernized.
