Legal regulations, economic factors and the need to protect forests against excessive exploitation encourage the entrepreneurs who use wood to look for its alternative sources. Among them there are almost fully utilized wooden by-products and wood waste wood, which constitute one of the elements of municipal waste. In the article the sources of post-consumer waste wood have been determined. Detailed analysis embraced one of them, namely – municipal waste generated within the territory of Wielkopolska Voivodeship. Their morphological composition has been given and the share of individual fractions in the total volume of municipal waste has been pointed out. The amount of waste wood possible to recover by 2023 was determined as the sum of those fractions of municipal waste, which contain wooden elements or wood-based elements: fraction wood and fraction bulky waste. Wooden packaging has been also included.

The article tries to find the best solution of the system, which aims to dispose of the waste stream, being at the same time an economically justified and socially acceptable system. In order to find the best possible system three strategies for dealing with waste were considered, evaluated by 11 criteria in line with sustainable development, included in the following groups: environmental, social, and economic. The evaluation criteria are used in the multi-criteria analysis, which is the final step in the decision-making analysis. The most effective solution selected is additionally dependent on the importance of specific criteria adopted for the calculations. The proposed methodology was used and verified in the selection of a waste management system for the city of Szczecin.

The object of our study is soil fertilized with a variety of compost produced from unsorted municipal waste maturing in heaps for different lengths of time, and with green waste compost. Municipal waste composts were applied at rates of 10 and 30 g·kg-1 soil, whereas green waste compost was introduced to soil as 10 g·kg-1 soil. Processes that take place during compost maturation have resulted in an increased concentration f polycyclic aromatic hydrocarbons. More PAHs were determined in municipal waste composts than in green waste compost. Fertilization of soil with municipal waste composts increased the content of PAHs in soil, but in most cases the natural concentration of these compounds was not exceeded. However, the total PAHs more than 200 μg·kg-1 d.m. soil, which is above the natural content, were observed in the objects where the highest rates of one- and three-month-old composts were applied. In the objects fertilized with green waste compost, total PAHs (as well as the levels of particular compounds) were close to the values recorded for the control object.

Our work concerns of the determinants that affect the management of municipal waste in sustainable regional development in Poland by analyzing the adequacy of income covering the costs of the new legal environmental waste management systems. We also present the results of research on the impact on local residents and the environment of the largest landfill in Europe, demonstrating a small influence on the life and health of local residents. This impact was much more correlated with smoking. We analyzed the choice of method for calculating charges for waste disposal and discuss the consequences of the introduction of the different options.

Subject and purpose of work: The purpose of this work is to present the problem of municipal waste management, and its use for the production of electric and thermal energy. Materials and methods: The information used is derived from the CSO publication for 2015 in the scope of the data on municipal waste and electric energy per province. To establish the rankings of provinces, the method of zero unitarisation was applied, whose task is to bring various variables to the state of comparability with different titres and orders of magnitudes; and then the results derivedfrom the two rankings were compared. Results: The rankings of provinces with respect to the state of waste management and obtaining electrical energy in Poland in 2015 were presented. These rankings are characterized by a significant degree of similarity. Conclusions: Regional differentiation in individual Polish provinces in 2015 is relatively moderate.

Wśród możliwych do zastosowania w rekultywacji zamkniętych składowisk odpadów komunalnych materiałów najbardziej dostępnym, a jednocześnie wartościowym są komunalne osady ściekowe. Celem niniejszej pracy było określenie możliwej do zastosowania dawki osadów ściekowych, wykorzystanych do ukształtowania warstwy próchnico twórczej. W analizie uwzględniono zawartość metali ciężkich w badanych osadach jako czynnika najsilniej ograniczającego wielkość dawki, a jednocześnie miąższość ukształtowanej warstwy próchnicotwórczej. Badaniami i analizą objęto osady ściekowe pochodzące z 3 mechaniczno-biologicznych oczyszczalni ścieków na terenie Międzyodrza w Szczecinie, Oczyszczalni Ścieków Tele-Fonika Kable S. A. (Oddział w Szczecinie - „Załom”) oraz Oczyszczalni Ścieków w Elektrowni „Dolna Odra” w Nowym Czarnowie. Po przeprowadzonych badaniach stwierdzono, że czynnikiem najbardziej ograniczającym rekultywacyjne wykorzystanie badanych osadów ściekowych okazała się wysoka w nich zawartość rtęci („Międzyodrze”, „Dolna Odra”) oraz miedzi („Załom”), co pozwala na zastosowanie osadów w ilości niespełna 1/10 dawki dopuszczalnej. Stwierdzono także, iż możliwa do zastosowania w celach rekultywacyjnych dawka osadów jest niewystarczająca do ukształtowania dobrej próchnicotwórczej warstwy rekultywacyjnej.

This study investigated the solid waste characterization of the city of Kocaeli. With this aim solid waste groups were analyzed for sub-municipalities of the city. Representative sampling points were determined in municipalities with populations over 5,000. Four different socio-economic groups (the downtown district plus low, intermediate, and high income levels) were investigated in the study. Characterization studies were performed for a 2-year period. In this context, 16 and 13 different solid waste species were categorized for winter and summer seasons, respectively. The results of the study showed that kitchen wastes constitute the highest proportion for all socio-economic groups despite dissimilarities in waste distribution of municipalities. It was followed by combustible wastes and plastic wastes. Reducing waste components into five groups as organic wastes, recycled wastes, hazardous wastes, combustible wastes and others, an increase was seen in amounts of recycled, hazardous, and combustible wastes in winter season, whereas the amount of organic wastes decreased. Investigating general waste distribution for different income levels without any seasonal distinction, it was observed that highest values of organic and recycled wastes were seen in the downtown district and high-income groups, whereas combustible, hazardous, and other wastes were higher in low-income groups. In general, as a result of the characterization study without any seasonal and/or economical distinctions, proportions of organic, recycled, combustible, hazardous wastes, and others were determined as 41.53%, 30.51%, 20.64%, 2.12%, and 5.20%, respectively.

A four-course crop rotation experiment was established in spring 2004 to study the effect of municipal waste compost on chemical composition (N, P, K, Mg) of commercial potato Jasia cv. and spring barley Justyna cv. In 2004 municipal waste compost and farmyard manure were applied at a rate of 10 t DM·ha⁻¹ (once in crop rotation). Unfertilized treatment and treatment with NPK fertilization (150 kg N, 65 kg P, 166 kg K·ha⁻¹) were used as control. Nitrogen fertilization was balanced to 150 kg·ha⁻¹, depending on organic N content in compost. In 2005 only mineral fertilizers were applied, at rates recommended for spring barley, i.e. 90 kg N, 26 kg P, 100 kg K·ha⁻¹. The composts tested in experiment affected the levels of macronutrients (N, P, K, Mg) in potato tubers, spring barley grain and straw. The highest nitrogen uptake by potatoes was recorded in the NPK-fertilized treatment and in the treatment with composted municipal green application (on average approx. 124 kg·ha⁻¹). In other cases nitrogen uptake was about 80 kg·ha⁻¹. Compost application was also conducive to macronutrient accumulation in potato tubers, especially when compared with the control treatment. Composts showed a positive after-effect on the removal of N, P, K and Mg with barley grain and straw yields.

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%.
