Our study tested the susceptibility of biodegradable films to degradation in non-industrial composting conditions. The qualitative and quantitative changes in the films studied were shown by the tests of strength, weight loss, and microscopic images. After about 9 weeks of composting, many hollows and pits appeared in the surface of the foils studied and their mechanical parameters were significantly decreased, which proved the loss of biodegradable components.

Research of the biodegradability of degradable/biodegradable plastic material in various types of environments. Research was carried out in order to assess biodegradability of degradable/biodegradable materials made of HDPE and mixed with totally degradable plastic additive (TDPA additive) or made of polyethylene (PE) with the addition of pro-oxidant additive (d2w additive), advertised as 100% degradable or certified as compostable within various types of environments. Research conditions were: (i) controlled composting environment – laboratory-scale, (ii) real composting conditions – domestic compost bin, (iii) real composting conditions – industrial composting plant and (iv) landfill conditions. The results demonstrate that the materials made of HDPE and mixed with totally degradable plastic additive (TDPA additive) or made of polyethylene (PE) with the addition of pro- -oxidant additive (d2w additive) or advertised as 100% degradable did not biodegrade in any of the above-described conditions and remained completely intact at the end of the tests. Biodegradation of the certified compostable plastic bags proceeded very well in laboratory-scale conditions and in real composting conditions – industrial composting plant, however, these materials did not biodegrade in real composting conditions – domestic compost bin and landfill conditions.

Throughout 13 months, the municipal sewage sludge from sewage-treatment plant in Stalowa Wola was composted with fly-ash from combusted hard coal from the Stalowa Wola power plant; they were mixed in the following proportions: 80% sludge + 20% ash, 70% sludge + 30% ash, 60% sludge + 40% ash, 100% sludge. In order to assess the changes in Pb, Zn, Cu and Cd contents in composted wastes, composts were sampled on the day the experiment started, then on the 8th and 29th days of composting, as well as after 2, 4, 6, 8 and 13 months after the experiment beginning. Two types of wastes used for composting: the municipal sewage sludge and the hard coal ash, had similar contents of lead (19.8 and 19.5 mg·kg⁻¹) and copper (62.8 and 52.8 mg·kg⁻¹), while lower contents of zinc (43.2 mg·kg⁻¹) and cadmium (0.36 mg·kg⁻¹) were found in ash. Composting resulted in changes of heavy metal contents in the fertilizers obtained, depending on the composition of material composted and the time for which the process was carried out. Considering metals present in the 6-month compost (the standard), the fertilizers examined fell into following series: Pb: sludge + 30% ash > sludge > sludge + 20% ash > sludge + 40% ash; Zn: sludge > sludge+20% ash > sludge + 30% ash > sludge + 40% ash; Cu: sludge > sludge + 30% ash > sludge + 20% ash > sludge + 40% ash; Cd: sludge > sludge + 20% ash > sludge + 40% ash > sludge + 30% ash.

The article mentions results from changes of physical properties of composted material during the composting process. Composting conditions in compost pile were simulated in five vessels with volume of 90 m3 under home conditions. Composted material was variously modified (mixing and turning, moistening, adding fresh material) during the composting process. Temperature and oxygen concentration inside vessels were measured, as well as reduction in volume of compost material during time, pH and electric conductivity of selected compost. It appeared that the temperature of the compost material in small volume in the compost pile was lower than the requirement for hygienization of the composted material. The temperature higher than 50°C was measured only sporadically and already during the first week of the experiment temperatures inside the vessels corresponded with outside temperatures. Oxygen concentration in all vessels was sufficient to ensure the aerobic process during the entire period of the experiment. The lowest measured oxygen concentration was higher than 10 %. These low values were measured only during the first week of the experiment, during the following weeks the oxygen concentrations exceeded 15% only with small exceptions. Reduction in volume of the composted material highly depended on whether the compost material was mixed and turned during the course of the composting process. Mixed and turned composted material was reducing its volume significantly, quicker than the composted material not being mixed and turned. The effect of moistening on the composted material was not proved. Measured pH values and electric conductivity (EC) values of the compost material from selected vessel K2 (composted material being mixed and turned, moistened, fresh compost material was not added) showed values fully corresponding with a quality well-matured compost. The average pH value was 7.76 with a standard deviation of 0.04 and the average EC value was 1.79 mS.cm-1 with a standard deviation of 0.27.

Contamination with bioaerosols most affects the livestock production, and especially the poultry. Prolonged or repeated exposure to high concentrations of airborne fungal spores is considered a major risk factor for human health and contributes to the deterioration of lung functions, and particularly allergic diseases. The aim of the study was to determine the number and quality of moulds and yeasts in the air of various objects for poultry post-slaughter waste processing. The study allowed to detect the presence of moulds and yeasts in the air of all sampling points. There were: Aspergillus sp., Penicillium sp., Scopulariopsis sp., Trichoderma sp., Acremonium sp., Cephalosporium sp., Alternaria sp., Pithomyces sp., Eurotium sp., and: Rhodotorula sp., Candida sp., Yarrovia sp. and Saccharomyces sp. Statistical analysis confirmed the presence of highly significant influence of the sampling point, date, and interaction of these factors on the fungi population.

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.

Different types of compost were made in a pilot plant, from pruning remains (percentages in volume ranging between 40-60%), leaf litter (20-30%), sewage sludge (0-10%), and biomass ash (0-20%). The aim of our study was to promote the utilization of plant remains to produce compost that, once stabilized and sanitized, could be used as an organic amendment and/or substrate. After six and a half months, all of the composts produced were stable, sanitized, and did not contain phytotoxic substances. However, the composts containing sludge and ash became stabilized and sanitized more rapidly than the others, and generally contained higher quantities of nutrients. The highest quality compost was produced by mixing 20% leaf litter, 10% sludge, 10% ash, and 60% pruning remains (% volume), and supplied highest quantities of phosphorus, calcium, magnesium, and potassium. This compost was categorized as class B, on the basis of the contents of chromium and zinc, i.e. it can be used as potting compost or mixed with other materials to lower the contents of chromium and zinc.

Due to frequent occurrence of pathogenic organisms in organic wastes, there is a need for a microbiological evaluation of the utilization process in the case of using them for agricultural purposes. The effectiveness of organic waste composting process using Kneer container technology was evaluated on the basis of Salmonella senftenberg W775 inactivation. The study was conducted during the spring, summer and autumn, placing specially prepared carriers in three layers of the composted biomass. In the top and middle layers the total elimination of the Salmonella rods was obtained. The inactivation rate of the bacteria in the bottom layer was slower.

Określono wpływ mieszania osadów ściekowych z tlenkiem wapnia, popiołem z węgla brunatnego, trocinami i słomą oraz kompostowania otrzymanych mieszanin na zawartość w nich wybranych metali ciężkich (Pb, Cr, Cd, Cu, Zn, Ni). Dodatek wszystkich użytych materiałów do osadów ściekowych zmniejszył zawartość ołowiu, miedzi i cynku w otrzymanych mieszaninach. Mniejszą zawartość chromu, kadmu i niklu w mieszaninach niż w samych osadach uzyskano po ich zmieszaniu z tlenkiem wapnia, trocinami i słomą. Dodatek popiołu z węgla brunatnego do osadów o niskiej zawartości chromu (z Siedlec), niklu (z Łukowa) i kadmu (obydwa rodzaje osadu) zwiększył zawartość tych pierwiastków w otrzymanych mieszaninach. W trakcie kompostowania uzyskano zwiększenie zawartości badanych metali ciężkich, zarówno w samych osadach, jak i w ich mieszaninach ze wszystkimi komponentami. Zwiększenie zawartości metali ciężkich w osadach z dodatkami mineralnymi było najczęściej mniejsze niż w samych osadach i ich mieszaninach z trocinami i słomą. W osadach ściekowych z Łukowa (stabilizowane w warunkach tlenowych) zwiększenie zawartości metali ciężkich w trakcie kompostowania było większe niż w osadach z Siedlec (po metanowej fermentacji).
