Landfilling is the most common and cheapest method of waste management practice in India. Municipal Solid Waste Landfills (MSWL) became a nuisance affecting the health, hygiene, sanitation and aesthetics of the surrounding area. Aggregates occupy almost 70% of concrete, so replacing waste materials with them could be a rewarding choice. In the current work, an experimental investigation is being carried out to test the addition of MSWL as a substitution with fine aggregate for concrete production. Out of the different aged samples available at the dumpsite, the most aged sample is chosen for experimental investigations according to the basic physical properties. Concrete mixes, with 0%, 4%, 5%, 7% and 10% partial replacement of fine aggregate with MSWL are tested for mechanical properties such as compressive strength, split tensile strength, flexural strength, and non destructive test and have proved to be a partial substitute for fine aggregate. Durability studies such as water absorption, acid attack and sulphate attack also gave better experimental proof for the sustainable reuse of this waste material. The research reveals 5% replacement is the optimum considering all the test result values. The paper leads to advanced research for the suitability of the material in the construction industry.

Celem niniejszej pracy była analiza składu pierwiastkowego zanieczyszczeń chemicznych i mikrobiologicznych występujących na nasionach bobiku uprawianego w bezpośrednim otoczeniu składowiska odpadów komunalnych. Skład pierwiastkowy zanieczyszczeń chemicznych na powierzchni badanych nasion oraz w glebie analizowano metodą EDS za pomocą mikroskopu elektronowego NOVA NANO SEM s 300. Analizy mikrobiologiczne przeprowadzono metodą seryjnych rozcieńczeń. Wyniki przeprowadzonych analiz wykazały na powierzchni nasion bobiku uprawianego na obszarze i w bezpośrednim otoczeniu składowiska komunalnego obecność zarówno makro- i mikroelementów, jak i pierwiastków z grupy metali ciężkich, a także występowanie bakterii i grzybów. Wykazano, że usytuowanie poletka względem składowiska miało istotny wpływ na stwierdzone na powierzchni nasion bobiku zanieczyszczenia chemiczne i mikrobiologiczne.

The aim of the work was to evaluate the effect of municipal solid waste landfill on the chemical and microbiological contaminants present on seeds surface of horse bean grown in its vicinity. Elemental composition of chemical contaminants on the seeds surface and in the soil was analyzed with the electron microscopy NOVA NANO SEM s 300 with EDS technique. Microbiological analyzes were performed by serial dilutions. Conducted analyses revealed presence of macro and trace elements, including heavy metals, as well as the presence of bacteria and fungi on the surface of faba bean seeds grown in the area of landfill and in its immediate vicinity. It has been shown that the localization of plot to the landfill had a significant effect on chemical and microbiological contaminants identified on the seed surface of horse bean.

W artykule opisano zastosowanie zdalnie sterowanych urządzeń typu zraszacze (instalacji „potopu tryskaczowego”) do gaszenia pożaru na wysypiskach twardych odpadów komunalnych. Stosowanie takich instalacji wymaga odpowiednich przepisów prawnych, przy tworzeniu których należy brać pod uwagę podstawowe dane taktyczne i techniczne urządzeń. Przedstawiony w artykule schemat układu jest wynikiem przeprowadzonych obliczeń hydraulicznych potrzebnych do zaprojektowania takiego urządzenia gaśniczego. Na podstawie tych obliczeń określono wymagane minimalne ciśnienie i prędkość przepływu wody, jakie jest wymagane dla projektowanego systemu gaśniczego.

The study was conducted to measure the emission from landfill in the years 2005– 2011. The results are used to diagnose the emissions of CH4. The mean value of CH4 in vol. % in the collection wells ranged from 0 to 2.14 vol. % the mean concentration of CH4 in mg/m3 ranged from 0 to 25 251 mg/m3, the average concentration of CH4 in mg/Nm3 at the measuring and control points ranged from 2.2 to 24.1 mg/Nm3. CH4 emissions from the landfill do not exceed the reporting thresholds the landfill does not meet conditions for being included in the Integrated Register of Pollutants.

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.

Discussion on counteracting the greenhouse effect focused on the reduction of CO2 emissions mainly from the fossil fuel burning. There is often forgotten that the important role in greenhouse effect play other gases, such as methane, but its production is weakly associated with the combustion of fossil fuels. The global warming potential for methane is approx. 25-fold higher than that of CO2.Methane is located at second place on the list of the substances responsible for rising the temperature of the Earth’ atmosphere. Taking into account the global action towards prevention the climate changes, a reduction of methane emissions should be enhanced. It could significantly improve the atmospheric air quality. The aim of the study was to evaluate the efficiency of bio-oxidation of methane and selected aromatic hydrocarbons emitted from municipal solid waste landfills. The research was carried out under field scale for 10 months, from early summer to early spring. An open type biofilter worked at variable loading rate of landfill gas and under different climatic conditions. Due to the low gas pressure inside the waste body, the gas suction was applied to provide a continuous gas flow to the biofilter. This was resulted in landfill gas dilution by atmospheric air migrating through the leakiness in the gas supply system. The study showed that the temperature was limiting factor in the processes of bio-oxidation of methane and monoaromatic hydrocarbons such as BTEXs in field scale biofilter. During winter season the realbed temperature fall below 0°C throughout the whole profile of the biofilter. This led to the freezing of the water contained in the soil pores, which prevented the flow of gas along the biofilter. In other seasons, where the average bed temperature ranged from 5.5 to 42.3°C, biofilter worked reaching the 100% efficiency of BTEXs removal, at average mass loading rate of 26.75 ug BTEXs m-2d-1, and 42% efficiency of methane removal at average mass loading rate of 14.6 g CH4 m-2d-1. High efficiencies of volatile organic compounds (VOCs) removal from landfill gas can be explained by dilution of gas stream entering the biofilter with the atmospheric air. Calculation of elimination capacity of particular VOCs and the evaluation of the impact of VOCs concentration on removal efficiencies was impossible due to their total oxidation in the biofilter.

The monitoring that was carried out at the landfill specialized in leachate, groundwater and surface water. There were 6 sampling sites. The observed parameters were pH, BOD5, CODCr, conductivity. Leachate reached the high values in all observed parameters. Groundwater samples were collected at two monitoring wells and the sampling site (A, B, C). Surface water was collected from two sampling sites (D, E). The pH showed slightly acid values at all sampling points. The pH of surface water was slightly acid to neutral. Both BOD5 and CODCr values remained stable over the reporting period. The average conductivity value at sampling points D, E remained constant. In line with the Czech National Standard ČSN 75 7221 “Classification of Surface Water Quality” sampling point D belongs to II Water Quality Class – slightly polluted water and sampling site E to Class I water quality – unpolluted water. The authors believe that the fluctuations occurring with regard to the values of certain samples were not caused by the operation of the landfill itself, but were a result of the intense agricultural activity nearby the landfill.
