Opis:: The changes in the waste management system that have been introduced in Europe and in the world were aimed at counteracting the emergence of illegal dumping sites and increasing the levels of waste recovery and recycling, so that waste management remains in line with the principles of sustainable development and circular economy. The change introduced in 2013 in the municipal waste management system in Poland concerned the assumption of full responsibility by municipalities for the municipal waste collected from owners of residential properties, as well as the establishment and organization of a charging system for residents for the collection and management of the waste. The purpose of the study was to conduct a comparative analysis of fees paid by residents of 93 selected communes of the Lubelskie Province. The study examined the impact of the amount of fees for the waste collection and management on the share of households declaring selective municipal waste collection, the share of selectively collected waste, and the mass accumulation rate of municipal waste. As a result of the analysis conducted using the data from the years 2013–2016, it was revealed that the amount of fees for the collection and management of waste in households that sorted waste contributed significantly to the increase in the percentage of selectively collected waste. Similarly, the smaller the value of the ratio of rates for sorted and mixed waste, the greater the segregation efficiency. This indicates that in the case of the analyzed region, the lower fee charged for sorting waste was an incentive for residents to sort waste.

Tytuł:: Impact of Air-Flow Rate and Biochar Addition on the Oxygen Concentration in Waste and Emitted Gases During Biostabilization of Undersized Fraction from Municipal Solid Waste

Opis:: Mechanical biological treatment of waste is still one of the most popular methods for mixed municipal waste treatment. The result of mechanical processing of waste is sorting out: the undersized fraction from municipal solid waste (UFMSW) with granulation below 80 mm, rich in biodegradable organic waste (mainly including food waste, paper, wood, etc.). UFMSW is treated in biological processes in order to reduce the negative environmental effect of this waste. Unfortunately, the processing is not neutral to the environment. The correct course of the aerobic biostabilization process depends on the activity of microorganisms, the intensity of aeration, and the oxygen content in the processed waste. The aim of this paper was to analyze the effect of air-flow rate and biochar addition on the oxygen concentration in waste and in emitted gases during the intensive phase of UFMSW biostabilization. The study was performed under laboratory conditions. Six different variants of the process (without biochar addition and using 1.5; 3; 5; 10 and 20% of biochar addition) were applied. Subsequent replicates were conducted using an averaged air-flow rate of 0.1, 0.2, and 0.4 m3∙d-1∙kg dm.org-1. As a result of the conducted experiments, it was found that both the air-flow rate and the addition of biochar have a significant effect on the oxygen concentration in the treatment waste, as well as its content in the outlet air. Using the highest air-flow rate resulted in the oxygen content not decreasing below 14%, both in the free spaces between the waste and in the emitted gases, while the addition of biochar significantly reduced the oxygen concentration. In the case of lower air-flow rate values, the oxygen content decreased even below 5%. It was found that a high addition of biochar (10 and 20% by weight) at the lowest air-flow rate resulted in the occurrence of anaerobic zones in waste in the first days of the intensive process (between days 2 and 6 of the process), as well as absence of oxygen in the outlet air (between days 2 and 4 of the process). Despite this, no methane (biogas) emissions were found in any of the conducted experiments.

Opis:: The issue discussed in this paper is related to the correlation between the efficiency of waste segregation and fee rate imposed on residents for generated municipal solid waste, which rate is set and changed by municipal authorities. The main objective of the paper was to analyse the variability of fees for waste collection and management, as well as to analyse changes within this scope during the first several years (from 1 July 2013 to 31 December 2016) since the new waste management system was implemented in Poland. The research area included the municipalities of the 1st Waste Management Region in the Silesian Voivodeship. The mean fee sustained by residents of the examined municipalities for the collection and management of mixed waste was PLN 14.1 per person per month; when residents opted for additional selective waste collection, the fee was PLN 7.3 per person per month. During the examined period, the waste collection fee increased in the majority of the municipalities by 34.0%. One third of the municipalities did not change the rate. In those municipalities where the fee increased, the growth of segregation efficiency was hampered. The mean share of the segregated municipal waste stream in the total stream of collected waste reached 22.6%. No significant correlation was observed between the applied fee rate and efficiency of selective waste collection.

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.
