Opis:: The article presents the results of investigations focused on the determination of mercury content in gas and solid samples. The emission of Hg was the result of coal combustion. The investigations were carried out in the selected power generation facilities operated with pulverized coal and circulating fluidized bed boilers. Analysis was carried out for the flue gases, as well as fuel and sorbent samples and the by-products of the combustion process (fly ash, slag, bottom ash, and the products of wet desulfurization technology). The determination of mercury content in solid samples was carried out using Lumex RA-915+ spectrometer with RP-91C attachment. The measurements of the mercury concentration in the flue gases were performed according to the cold vapor technique. The analysis of the results indicated that the main source of mercury is coal, but significant concentration was also determined for the biomass co-combusted in one of the facilities. Considerable amounts were also determined in fly ash and wet FGD (flue gas desulfurization) samples.

Opis:: The environmental legislation in Ukraine is changing rapidly. These changes are related to the adaptation of Ukrainian laws to the requirements of the European Union. In this regard, the paper considers the unintentional production of Persistent Organic Pollutants (POPs) in the Odessa Industrial-and-Urban Agglomeration (next – Odessa agglomeration) in the context of new regulatory and legal requirements of Ukraine. In many countries around the world, the issue of pollution of environmental components by POPs has a large focus, because POPs pose a global threat to the environment and human health. The work aims to assess the main sources of unintentional production of POPs in the Odessa agglomeration during one year (2017), taking into account the new territorial features of the Odessa agglomeration. For the first time for Odessa agglomeration, the mass of POPs formed by main sources using the newest European methodological approach was calculated, sources of unintentional production of POPs on volumes of these substances were ranked, and their total mass of generation on the territory of Odessa agglomeration was calculated. The number of POPs molecules equivalent to 2,3,7,8-TСDD, which infiltrate into the air basin of the Odessa agglomeration, hence into the organisms of the agglomeration inhabitants, was calculated. The obtained results were compared with the allowable number per capita of the agglomeration, the relevant conclusions were drawn. Priority sources of unintentional production of POPs were identified, which allows taking appropriate preventive measures to reduce the scale of their generation.

Opis:: Electricity generation from swine wastewater using microbial fuel cell (MFC) was investigated Swine wastewater was collected into a dual-chambered (aerobic and anaerobic) fuel cell. The maximum power output using copper and carbon electrodes were 250.54 and 52.33 μW, respectively, while 10.0 and 5.0 cm salt bridge length between the cathode and anode gave maximum power outputs of 279.50 and 355.26 μW, respectively. Cathodic potassium permanganate and distilled water gave maximum power outputs of 1287.8 and 139.18 μW, respectively. MFCs utilized microbial communities to degrade organic materials found within wastewater and converted stored chemical energy to electrical energy in a single step. The initial bacterial and fungal counts were 7.4×10⁶ and 1.1×10³ CFU ml^-1. Bacterial counts steadily increased with time to 1.40×10⁷ CFU ml^-1 while fungal count declined to 4.4×106 CFU ml-1 after day 60. The decline in microbial counts may be attributed to the time necessary for acclimatization of microbes to the anode. The genera identified were Bacillus, Citrobacter, Pseudomonas, Lactobacillus, Escherichia coli, Aspergillus and Rhizopus. These microbes acted as primary and secondary utilizers, utilizing carbon and other organics of the wastewater. Chemical parameters indicated that the biochemical oxygen demand decreased from 91.4–23.2 mg/L, giving 75% while the chemical oxygen demand ranged from 243.1–235.2 mg/L, representing 3.3% reduction. Although, the metabolic activities of microbes were responsible for the observed degradation, leading to electricity, the overall power output depended on the distance between the anode and cathode ompartments, types of electrode materials and mediators and oxygen reaction at the cathode.

Opis:: Millions of tons of urban solid waste are discarded yearly in Mexico. The rapid population growth, urbanization, and social development, together with a more significant number of inhabitants, resulted in a massive amount of municipal solid waste (MSW) that is increasing yearly. Most of these end up in landfills without being used for energy, causing severe social and environmental problems. Municipal solid waste (MSW) is the most significant main waste stream (representing 9.21% of the waste that can be used), including plastic bottles, food dishes, cans, bags, and containers. The recycling and sustainable disposal of plastic waste is a significant activity with a high rate of complexity due to various effects that occur during its processes, such as obstructions in mechanisms and pipes, prolonged degradation and biodegradation rates, and the presence of additives, and highly toxic dyes. Pyrolysis is one of the promising technologies for converting waste into sound energy capable of being used in various applications such as power generation, transportation fuel, and multiple thermal purposes. According to the Ministry of Energy (SENER), Mexico has an installed generation capacity of 86,034 MW, of which almost 65% is based on fossil-based technologies.

Opis:: The article presents the analysis of waste heat emission in a typical industrial installation. On the basis of the process monitoring system, periodic analyses of fumes composition, installation process manual and the conducted measurements of the heat fluxes from individual sources emitting heat on the way of natural convection from the devices’ coats and forced convection in the fumes flux were calculated. According to the authors the heat of temperature 140–155 °C and surface power density 860–970 W/m² emitted by devices’ covers can be reclaimed in ORC techniques, Peltier’s modules and the systems realising Stirling cycle. Part of the waste heat included in fumes, which makes c.a. 76% of the total emission from the installation, should be returned to the process of fuel oxidation, what will reduce the emission by c.a. 18% and the volume of consumed fuel by c.a. 25 m³ CH4/h, according to the presented calculations.

Opis:: Solid biomass plays a leading role in the development and dissemination of technologies pertaining to the usage of renewable raw materials. The biomass processed into solid biofuel requires special logistic operations. Distribution from the place of production, handling and storage of biofuel are basic and necessary elements of the chain of fuel supply to the energy source. Solid biofuels for energy use occur in different forms which affect the costs of logistic operations. Rational heat generation requires choosing a specific type and form of biofuel, assessing the availability of raw materials, integrating fuel management with energy source technology and, above all, determining the cost of energy generation. The cost of energy generation includes the cost of fuel and logistic operations, which depend mainly on a type and form of fuel. Currently, the commonly used biofuels are wood chips, straw and pellets. This paper presents a comparison of heat demand of 400 kW, 600 kW and 1 MW boiler plants generating heat for the purpose of heating buildings and water. The analysis took into account three forms of biofuels: compressed, crushed and granulated forms resulting from different types of biomass (straw, woodchips, pellets). The cost of heat generation in the aspect of biofuel management and the share of particular cost components in heat production were determined. It was shown that in medium power boiler plants, the granulated fuel has the lowest cost of biomass distribution, whereas wood chips have the lowest cost of heat production.

Opis:: Hazardous and toxic waste are not only produced by industry, but also by households. But in fact, the household activities also produce Household Toxic and Hazardous Waste (HTHW). Considering the potential of the impact of HTHW to worsening environment quality, the effort of HTHW management must have been started well. One important aspect in the management strategy is to determine the characteristics and the HTHW generation. The method used to determine the characteristics HTHW refers to SNI 19–2454–2002, while the calculation of HTHW generation refers to the SNI 19–3694–1994 calculated based on weight and volume. Sampling was conducted in four districts of Semarang (Pedurungan, Semarang Barat, Semarang Utara and Banyumanik). The samples used in this study were 400 families that were selected based on the proportion of Slovin Formula. Data analysis performed using Analysis of Variance (ANOVA) and Kruskal-Walis test (α = 0.05). The largest characteristic of HTHW in Semarang City is infectious (79%), further Poisonous (13%), Combustible (6%) and Corrosive (2%). While HTHW generation is 0.01 kg/person/day (5.1% MSW). Statistical test result showed there was a significant difference (p-value : 0.001) between HTHW generation based on economic level, but there was no significant difference (p-value :0.442) between HTHW characteristics in Semarang city. The level of education, occupation, income level and lifestyle may become potential factors in differentiating the characteristics and HTHW generation in Semarang city.

Opis:: In recent years, much research has focused on energy recovery from biomass as an alternative to fossil fuel usage. Microbial fuel cells (MFCs), which produce electricity via microbial decomposition of organic matter, are of great interest. The performance of an MFC depends on the electrode material; most often, carbon materials with good electrical conductivity and durability are used. To increase the power output of an MFC, the anode material can be modified to reduce the internal resistance and increase the anode surface area. Therefore, this study determined how modifying a carbon felt anode with reduced graphene oxide (rGO) and a combination of rGO with iron (III) oxide (rGO-Fe) affected electricity generation in an MFC fueled with wastewater. A mixed microbial consortium was used as the anode biocatalyst. The MFC-rGO-Fe produced significantly higher voltages than other cells (average 109.4 ± 75.1 mV in the cycle). Power density curves indicated that modifying the anode with rGO-Fe increased the power of the MFC to 4.5 mW/m2, 9.3- and 3.9-times higher than that of the control MFC and the MFC-rGO, respectively. Anode modification reduced the internal resistance of the cells from 1029 Ω in the control MFC to 370 and 290 Ω in the MFC-rGO and MFC-rGO-Fe, respectively. These results show that a mixture of rGO with iron (III) oxide positively affects electricity production and can be successfully used for anode modification in the MFCs fueled with wastewater.

Opis:: Low-temperature heat sources have become increasingly popular in recent years, particularly for energy generation. The majority of thermal devices in the market (including devices using solar energy, geothermal energy, waste energy, and so on) transform heat into electricity indirectly, requiring mechanical work before producing power. Through the Seebeck effect, the technology that employs a thermoelectric generator (TEG) may directly transform heat energy into electricity. The TEG technology provides several advantages, including compactness, quietness, and the absence of moving components. TEGs have a low thermal and electrical efficiency, which is one of their main drawbacks. Therefore, the performance of a thermoelectric generator is improved by employing liquid evaporation heat transfer in this manuscript. The performance of the thermoelectric was examined experimentally and compared to the liquid evaporation mode under varied heat flux values and different modes of heat transfer in terms of free and forced convection with and without fins. The experimental results revealed that when compared to free convection without fins, adopting forced liquid evaporation convection would improve TEG voltage variation by 435.9%.

Opis:: Microbial fuel cells (MFCs) pertain to a kind of modern technology for the direct conversion of chemical energy in organic matter from wastewaters into electricity during the oxidation of organic substrates. A system of continuous MFC was constructed for the treatment of real petroleum refinery wastewater (PRW). The treatment of real PRW, operational performance of the MFC system, biodegradation of furfural, and energy output were investigated in this study. The MFC was inoculated by mixed anaerobic bacteria, with Bacillus sp. as the dominant type, and continuously operated for 30 days. The biodegradation of furfural and phenol, which are the most prevalent toxicants in refinery wastewater, was investigated. The MFC system reached maximum energy outputs of 552.25 mW/m3 and 235 mV. In the anodic chamber, the maximum removal of furfural and phenol was higher than 99%, with biodegradation of organic content reaching up to 95%. This study demonstrated the viability of a continuous-flow MFC system as a green technology for the treatment of furfural-rich real refinery effluents while generating electricity.

Opis:: This paper studies the environmental impact of two different forms of solar power generation in Thailand – that of multicrystalline silicon solar cells, and that of thin film amorphous silicon solar cells. It takes as its study two of the largest solar cell power plants of their kind in Thailand; a multicrystalline silicon plant in the north (generating 90 MW) and a thin film amorphous silicon plant in the centre (generating 55 MW). The Life Cycle Assessment tool (LCA) was used to assess the environmental impact of each stage of the process, from the manufacture of the cells, through to their transportation, installation and eventual recycling. The functional unit of the study was the generation of 1 kWh of power transmitted and distributed by the Electricity Generating Authority of Thailand (EGAT) and Provincial Electricity Authority (PEA). The environmental impact results were calculated in terms of eco-points (Pt) per functional unit of 1 kWh. The characterised data for 1 kWh of solar power generation was then compared with data for 1 kWh of combined cycle and thermal power generation (both in Thailand), using the same set of characterisation factors. After analyzing the results, both forms of solar power energy generation were found to impact upon the studied categories of Human Health, Ecosystem Quality and Resource Depletion, whilst also highlighting the importance of the solar cell module recycling process in decreasing the overall environmental impact. When the two solar cell technologies were compared, the overall impact of the multicrystalline silicon solar cell was found to be higher than that of the thin film amorphous silicon solar cell. Furthermore, when assessing the overall impact against non-renewable power generating technologies such as combined cycle and thermal power generation, the thin film amorphous silicon solar cells were found to have the lowest environmental impact of all technologies studied.

Opis:: The energy sector worldwide is a significant source of air pollutant emission. In Poland, the vast majority of heat and electricity is generated in coal-fired heat and power plants. There is a common belief that high greenhouse gas emissions from the energy sector in Poland are mainly due to the technological processes involving the conversion of energy by burning fossil fuels. However, coal mining also causes a high environmental burden. This paper aimed to determine the carbon footprint of a typical hard coal-fired heating plant in Poland, taking into account mining of hard coal, its transport to the heating plant and useful energy generation in the heating plant. The investigation carried out allowed comparing the process steps and determining which of them is the dominant source of the greenhouse gas emissions. The obtained results show that hard coal mining and hard coal transport account for almost 65% and 5% of total equivalent carbon dioxide emission, respectively. Energy transformations in the heating plant account for 30% of total equivalent carbon dioxide emission, where approx. 29% is due to hard coal burning and 1% due to electricity consumption. The relative shares of carbon dioxide, methane and nitrous oxide in total equivalent carbon dioxide emission account for approx. 91%, 4% and 5%, respectively.

Opis:: Recently, studies have been carried out on an implementation of aerobic granular sludge (AGS) technology in full-scale wastewater treatment plants. The aim of the work was to evaluate the effectiveness of organic, phosphorus and nitrogen compounds removal from municipal wastewater and to characterize the biomass in a wastewater treatment plant upgraded from the activated sludge to AGS technology. In the upgraded facility, granulation was obtained quickly and it was observed that the granule morphology depended of the temperature. In the granular biomass harvested at moderate temperatures in the reactor (15°C), the granules with diameters in the range from 125 to 500 μm constituted the largest share (about 60%), while the second-largest biomass fraction comprised the granules with diameters over 1 mm (25%). The analysis of granule diameters carried out in winter (the temperature in the reactor equaled 8°C) showed a decrease in the share of the largest granules and predominance of the granules with diameters in the range from 90 to 355 μm (about 75%). Upgrading the municipal wastewater treatment plant from activated sludge to aerobic granular sludge significantly improved the settling properties of the biomass and efficiency of wastewater treatment. The average efficiency chemical oxygen demand (COD) and phosphorus removal increased by about 10% and 20%, respectively, while ammonium nitrogen was completely oxidized, regardless of the season. After modernization, the concentration of nitrates in the effluent increased significantly to about 3-6 mg/L. The results of the study show that it is possible to effectively upgrade the existing facilities to aerobic granular sludge technology; it was also proven that this technology is an excellent alternative to a conventional activated sludge.
