Opis:
Polska, przystępując do Unii Europejskiej, przyjęła cele Dyrektywy Rady 1999/31/WE z 26 kwietnia 1999 r. w sprawie składowania odpadów, deklarując jednocześnie zmniejszenie ilości odpadów deponowanych na składowiskach m.in. na rzecz recyklingu. Jednak, mimo licznych inicjatyw podejmowanych zarówno na szczeblu regionalnym, jak i krajowym, świadomość ekologiczna Polaków jest nadal niska, a dodatkowo rosnące koszty utylizacji nie sprzyjają właściwemu zarządzaniu odpadami. W rozdziale przedstawiono analizę porównawczą wad i zalet systemu zarządzania odpadami komunalnymi w wybranych gminach województwa śląskiego i łódzkiego. Opierając się na danych statystycznych za rok 2020 dla gminy Częstochowa i Gorzkowice, przeanalizowano istniejące rozwiązania zmierzające do minimalizacji i właściwego postępowania z odpadami. Wykazano korzyści i wady płynące z systemu wprowadzonych zachęt i kar, w szczególności w odniesieniu do naliczanych przez gminy stawek za wywóz odpadów. Efektem przeprowadzonej analizy było zaproponowanie rozwiązań zmierzających do poprawy systemu zarządzania odpadami komunalnymi w analizowanych gminach, a w szczególności do podniesienia świadomości ekologicznej mieszkańców, co przełoży się na wzrost poziomu recyklingu i odzysku odpadów zebranych selektywnie.
By joining the European Union, Poland adopted the objectives of the Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste, declaring at the same time a reduction in the amount of waste deposited in landfills, e.g. for recycling. However, despite numerous initiatives undertaken both at the regional and national level, the ecological awareness of Poles is still low, and, additionally, the growing costs of disposal are not conducive to proper waste management. The chapter presents a comparative analysis of the advantages and disadvantages of the municipal waste management system in selected communes of the Śląskie and Łódzkie voivodships. Based on statistical data for 2020 for the communes of Częstochowa and Gorzkowice, the existing solutions aimed at minimizing and proper handling of waste were analyzed. The advantages and disadvantages of the introduced system of incentives and penalties have been demonstrated, in particular with regard to the rates charged by the communes for waste disposal. As a result of the analysis, solutions were proposed to improve the municipal waste management system in the analyzed communes, and in particular to raise the ecological awareness of the inhabitants, which will translate into an increase in the level of recycling and recovery of selectively collected waste in the analyzed communes.

Opis:
Indonesian municipal solid waste (MSW) is dominated by biodegradable MSW (organic and paper). Due to the degradation process, the physical and hydraulic characteristics of these components can change. It is important to study the physical and hydraulic characteristics of MSW, because landslides occurred in several landfills in Indonesia after heavy rains. Field observations showed that landslides occur due to reduced paper components in the landfill (due to high recycling activities), and cause high percolation of water into the landfill. In the research, 38 samples consisting of two variants of MSW samples (organic and 80% organic + 20% paper), were prepared under the conditions of optimum moisture content. The organic sample of MSW is leaf, while the paper sample of MSW is newspaper, which were shredded to a diameter of about 1 cm. The tests of moisture content, bulk density (in the mould of permeameter), particle size distribution, and permeability were carried out on both sample variants for 90 days, with a test frequency of once in 5 days. The results showed that there was an increase in the moisture content and density, and a decrease in particle size and permeability in both variants of MSW sample. Organic MSW + paper has lower permeability and higher density than organic MSW. This requires further study, because a high paper recycling ratio can lead to a change in the landfill characteristics.

Opis:
This paper deals with the estimation of methane emissions from the Mirash municipal solid waste sanitary landfill. The methane emission was calculated according to two different methodologies, namely, IPCC 2006 and LandGEM. Within the framework of the research, the following parameters were evaluated: the amount of landfilled waste, landfill characteristics, and composition of landfilled waste as well as the climate conditions prevailing in the region. According to the IPCC methodology, the total amount of methane emitted from the Mirash landfill during the period 2006–2017 was 30.57 Giga grams (Gg), while according to the LandGEM methodology, the total amount of methane emitted from the Mirash landfill in the period 2006–2017 was 26.32 Giga grams (Gg). The total mass of CH4 in the Mirash regional landfill for the years 2018–2025 is projected to be 53.74 Gg according to the IPCC method, while according to LandGEM method, the projection points to 50.74 Gg. This study was carried out for the sanitary landfill for solid waste management in Mirash, Prishtina Region, in the Republic of Kosovo, during the year of 2018.

Opis:
Hydrothermal carbonization (HTC) is known as a thermochemical converting of wet biomass into a coal-like solid fuel (hydrochar). Hydrochar is easily crumbled. Because of hydrophobic properties, hydrochar is difficult to degrade by microorganisms. It has a calorific value comparable to lignite coal. In this study, hydrochar was made via converting the organic fraction of municipal solid waste through HTC at 190, 210, and 230°C for 30 min with feed to water ratio (FWR) 0.1, 0.2, 0.3. The feedstock processed includes food waste, paper, and wood waste, represented as a pseudo-component of the organic fraction of MSW. The high heating value (HHV), FTIR, as well as proximate and ultimate analyses were applied both to feedstock and hydrochar. The results showed that the energy density of hydrochar was elevated with increasing HTC temperature. The energy densification ratio and heating value increased by approximately 1.0–1.32 and 30%, respectively compared to raw feedstock. The lower yields of hydrochar were obtained at higher temperature. The typical char yields for lignocellulosic material range between 62–63 wt% at 190 °C and reduce to 54–57 wt% at 230 °C. Furthermore, a preliminary study of kinetic model for lignocellulose decomposition was conducted. This model was based on the mass loss rate of the lignocellulose compound in HTC of MSW. Three first-order reactions were given to illustrate the hydrochar yield at of 190, 210, and 230°C. The activation energy of lignocellulose decomposition was 76.26 kJ/mol, 51.86 kJ/mol, 12,23 kJ/mol for lignin, cellulose, and hemicellulose decomposition, respectively.

Opis:
A sustainable performance evaluation of pilot-scale was carried through horizontal sub-surface Constructed Wetlands system for treating the leachate from constructed Municipal Solid Waste Landfill at Institute of Environmental Engineering and Management, Mehran University of Engineering and Technology Jamshoro. The CWs were planted with Phragmites australis, Typha latifolia and Scirpus validus with sand and gravel. The leachate had been treated with two different cycles, first cycle was performed in the winter season whereas second cycle in summer, to differentiate the performance with seasonal variation. Chemical parameters of leachate pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids TSS, Ammonia-nitrogen (NH3-N), Nitrate-nitrogen (NO3-N), Total Phosphate PO43- (TP) and heavy metals, Lead (Pb) and Copper (Cu) were tested with intervals of certain weeks. The tests result showed that all parameters experienced a considerable reduction in their concentrations. Significant reduction efficiencies were recorded for parameters, BOD with 53–82%, COD with 32–46%, TSS with 59–75%, NH3-N with 90–92%, NO3-N with 85–87%, and TP with 48–64%, and heavy metals Pb and Cu with 28–48% respectively in four weeks of the first cycle by all three plants. Whereas, in the second cycle, the removal efficiencies of BOD 78–93%, COD 63–76%, TSS 52–83%, NH3-N 90–91% and NO3-N 91–92% and heavy metals Pb and Cu with 21–58% respectively in five weeks were observed by all three plants. Along with the experimentation, United Nations Sustainable Development Goals UN SDGs are also highlighted. This study helps achieving tremendous SDGs accompanying treatment of leachate.

Opis:
Municipal solid waste (MSW) compost supplied from the Istanbul Solid Waste Recycling and Composting Facility was used to amend soil samples collected within the boundaries of Istanbul. Cat grass (Dactylis glomerata cat grass) seeds were sown in the prepared samples. Plant development was observed for 90 days. pH, Cd, Cu and Ni concentrations in plant samples were measured at the end of every month. Concentrations of forms of Cd, Cu and Ni forms in soil were determined at the beginning and at the end of 90 day period (with sequential extraction). The effect of MSW compost on the transfer of Cd, Cu and Ni from the soil to the plants and the change in the forms of heavy metals in soil was determined. Results of sequential extraction showed that, adding compost into the soil changed the forms of these metals in soil. Plant uptake of Cd decreased, however, those of Ni and Cu increased. Cu concentration in plants that grew in soil with 3 wt. % of compost added reached 136.4 μg/kg.

Opis:
The amount of generated waste has been increasing for several years in Poland. There is a lot of research in the field of the environmental and economic evaluation of waste treatment processes. Waste transport is considered to be one of the most important elements of waste management (WM), because it integrates the whole WM system. The environmental impact of waste transport is rising (emissions to air). The European Union introduced provisions on the principle of proximity in the Waste Framework Directive. This principle suggests that waste should generally be transported, treated or disposed of as near to its place of origin as possible. The main aim of the study was to perform an ecological and technical-economic analysis of transportation of selected types of waste (mixed municipal solid waste, construction and demolition waste, separately collected waste called: segregation). The research applied data obtained from a municipal enterprise operating in the South Poland. SimaPro 8.1 software with Ecoinvent 3.3 database was employed to calculate the environmental impact. As a result of the analysis, it was found that the transportation of 1 Mg construction waste had twice as much negative impact on the environment as transportation of 1 Mg mixed municipal waste and segregated waste. This is connected with higher fuel consumption per 1 Mg of transported construction waste and twice the distance that an average hooklift truck must cover in order to collect 1 Mg of construction waste.

Opis:
In pursuance of the Saudi vision 2030, the Al-Hasa municipality has been allocating a total of US$ 60.1 million since 2018 to the implementation of a modern Municipal Solid Wastes (MSW) management system. In addition to the improved old components, the system involves six new-engineered cells, five of which will be gradually implemented in progresses, two waste sort-out lines station, and LFG energy recovery. The present research aimed at investigating the environmental and economic impacts of this MSW management system. For this purpose, the authors applied the Life Cycle Analysis (LCA) and Life Cycle Costs Analysis (LCCA) approaches. The main results showed that the air quality was not affected. For instance, gas emission, like carbon monoxide, was less than 0.1 ppm. However, soil and groundwater were contaminated due to leachate infiltration from the uncontrolled cell in which Chloride, Nitrate, and Sulfate exceeded the maximum limits. As for noise, it was found to be high near the sorting-out station at 71.1 Leq dBA. In terms of the financial aspect, the improved MSW management was relatively feasible despite its high costs over its revenues. Thus, the negative cash-flow could be supplemented by setting household taxes at US$ 29 per capita per year, which makes the project cost-effective. Thus, the research recommends continuing the MSW management project.

Opis:
Zawiesiny sporządzone z konwencjonalnych popiołów lotnych stosuje się z powodzeniem w technologiach górniczych do podsadzki samozestalającej, do doszczelniania zrobów czy w profilaktyce przeciwpożarowej. Wykorzystanie w ten sposób popiołów powstających w czasie termicznego unieszkodliwiania odpadów komunalnych jest niemożliwe ze względu na ich własności chemiczne (odpad niebezpieczny). Zbrylanie tego typu odpadów, a zwłaszcza ich granulacja z cementem i/lub specjalnymi dodatkami, zmniejsza wymywalność wielu jonów toksycznych, co umożliwia ich zastosowanie jako dodatku do mieszaniny samozestalającej. Celem niniejszej pracy jest określenie wpływu dodawania zgranulowanych popiołów ze spalania odpadów komunalnych na własności zawiesin popiołowo-wodnych przed zestaleniem i po zestaleniu.
Dense mixtures of conventional fly ashes and water are utilized in many modern mining operations as an underground mine paste backfill, structural fills, fire prevention. The use of MSW fly ashes in such operations are limited as a result of their chemical composition. In this case, the compaction process, accomplished with the use of binder such as Portland cement and/or others, immobilizes the reactive components of this waste and results in the formation of strong granules which remain impervious to leaching. This unables addition of compacted waste to the mixture of fly ash-water. The main purpose of this paper is to evaluate the influence of addition of compacted MSW fly ashes on the properties of fresh and hardened fly ash-water pastes.
