AB  - The utilization of construction and demolition debris in industrial wastewater treatment by sorption of Co2+ and Ni2+ ions was investigated. Selected waste composites are cost-effective and locally available, still their sorption characteristics and application are not sufficiently investigated. The samples of concrete, facade, ceramic materials, and asphalt were characterized in terms of mineral and surface composition, radioactivity, and stability at different pH values, as well as pH values of suspension and filtrate and electrical conductivity of the filtrate. The sorption capacities were determined in batch experimental conditions in one- and multi-component solutions. Characterization showed different crystal structures and mineralogical compositions of components. The results of gamma spectrometry confirmed the radiological safety of samples. Based on stability testing results, waste materials are suitable for further utilization and do not pose any risk to the environment. The overall sorption results suggested that cement-based materials, in addition to high affinity for the tested ions, represent a sorbent that binds contaminants firmly enough, reduces their mobility and bioavailability, and are suitable for removing Co2+ and Ni2+ ions from waste waters.

AB  - For efficient operation of heating and cooling grids, underground thermal
energy storage (UTES) can be a key element. This is due to its ability to
seasonally store heat or cold addressing the large mismatch between supply and
demand. This technology is already available and there are many operational
examples, both within and outside a district heating network. Given the range
of available UTES technologies, they are feasible to install almost everywhere.
Compared to other storage systems, UTES have the advantage of being able to
manage large quantities and fluxes of heat without occupying much surface area,
although the storage characteristics are always site specific and depend on the
geological and geothermal characteristics of the subsoil. UTES can manage fluctuating
production from renewable energy sources, both in the short and long term,
and fluctuating demand. It can be used as an instrument to exploit heat available
from various sources, e.g., solar, waste heat from industry, geothermal, within the
same district heating system. The optimization of energy production, the reduction
in consumption of primary energy and the reduction in emission of greenhouse
gases are guaranteed with UTES, especially when coupled with district heating
and cooling networks.

AB  - The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal of this investigation is to determine drying characteristics of nectarine pomace as a waste from food industry. The measurements were performed in an experimental dryer by combined conductive-convective drying method with disk-shaped samples of 5, 7, and 10 mm thickness and 100 mm in diameter at the air temperatures of 30, 40, 50, 60, and 70 degrees C, hot plate temperatures of 50, 60, and 70 degrees C and air velocity of 1.5 m/s. The drying curves were compared to a few semi-theoretical mathematical models. The Logarithmic model showed the best correlation. On the basis of experiments, it is determined that the drying process takes place in a falling rate period and it is accepted that the main mechanism of moisture removal is diffusion. The effective coefficient of diffusion was determined using experimental results by calculating the slope of the drying curves. Drying time and equilibrium moisture are determined for each experiment. Analysis of drying curves showed that the conductive-enhanced drying method reduces drying times and increases the diffusivity coefficient. The character of drying rate curves for conductive-enhanced drying was analysed and compared with pure convective drying of nectarine pomace.

AB  - Two most common systems of forest biomass supply chains in Serbia are evaluated by using the Life Cycle Assessment (LCA) approach: 'cut-to-length' system with penduculate oak (CLO) on flat terrains with a tractor equipage, and 'tree-length' system with moesian beech (TLB) on more steep terrains, with a skidder. The main focus is put on the fuel consumption and its environmental impact on various stages of wood chips supply chain. Results indicate chipping as a most environmentally burdensome due to the low process productivity and high diesel combustion in outdated machines. CLO system exhibits lower environmental burden due to the 2%-35% lower impact in six out of eleven analysed impact categories compared to the TLB. The main reason is the skidding performed on a more steep terrain with a more powerful machine consuming more diesel than the tractor equipage. The higher impact of the felling operation in CLO system is caused by additional time for processing short oak assortments. The evaluated environmental impacts are consequence of the machinery old age used in Serbian forests. The application of a modern, energy efficient, combined machines such as harvesters and forwarders is recommended though it could have a lot of drawbacks.

The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral binders (cement or lime), pozzolanic materials (zeolite and fly ash), and water. The favorable heat transfer behavior of composites based on Miscanthus x giganteus bio-fibers was already affirmed by literature data of similar natural bio-fiber materials, the author's previous experimental results, and consideration of dynamic heat transfer processes in the insulated outer wall exposed to variable ambient conditions. The experimental assessment was focused on the bearing capacity (i.e. compressive and flexural strength), water absorption, and durability (i.e. resistance to freeze-thaw and carbonation), because there is scarce literature data regarding these properties, whose thorough understanding and systematization are highly important for a wider application of biomass-based thermal insulation materials. The obtained results were evaluated through the comparison to published data from similar bio-based thermal insulations, as well as from conventional thermo-insulation materials such as polystyrene and stone or glass wool.

AB  - The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that effects of competition may significantly influence the efficiency of the treatment, the Simplex Centroid experimental design was used to explore ions sorption from multi-component solutions. For the purpose of this study, the common components of construction and demolition waste, such as pathway concrete and different bricks samples, were used along with the multi-component Sr2+, Co2+, and Ni2+ ions solutions. The equations for the prediction of metal ions sorption capacities were derived. The coefficients that correspond to the linear and interaction terms were obtained using a special cubic model. Likewise, by analysis of variance, statistically significant terms of the obtained polynomial were defined. The investigation has shown that the most effective sorption was onto the pathway concrete for all three cations, while the highest sorption capacity was found for Co2+ ions. Also, it has been determined that concerning Sr2+ ion removal there was a competition with coexisting Co2+ and Ni2+ ions, reducing its sorption capacity, while sorption of Co2+ and Ni2+ occurred more independently on other cations in multi-component solutions. Based on the obtained results, the applied experimental design can be efficiently used for the description of competitive sorption process and could be a powerful tool for the prediction of cation immobilization in liquid radioactive waste treatment.

Given that the liquid radioactive waste usually has a complex composition and that effects of competition may significantly influence the efficiency of the treatment, the Simplex Centroid experimental design was used to explore ions sorption from multi-component solutions. For the purpose of this study, the common components of construction and demolition waste, such as pathway concrete and different bricks samples, were used along with the multi-component Sr2+, Co2+, and Ni2+ ions solutions. The equations for the prediction of metal ions sorption capacities were derived. The coefficients that correspond to the linear and interaction terms were obtained using a special cubic model. Likewise, by analysis of variance, statistically significant terms of the obtained polynomial were defined. The investigation has shown that the most effective sorption was onto the pathway concrete for all three cations, while the highest sorption capacity was found for Co2+ ions. Also, it has been determined that concerning Sr2+ ion removal there was a competition with coexisting Co2+ and Ni2+ ions, reducing its sorption capacity, while sorption of Co2+ and Ni2+ occurred more independently on other cations in multi-component solutions. Based on the obtained results, the applied experimental design can be efficiently used for the description of competitive sorption process and could be a powerful tool for the prediction of cation immobilization in liquid radioactive waste treatment.",

AB  - In this paper "well-to-pump" environmental analysis of pyrolytic diesel from Miscanthus gigantheus is performed. The average annual yield of Miscanthus from III-V year of cultivation on 1 ha of chernozem soil in Serbia (23.5 t) is considered as an input for the process. Two pyrolytic diesel pathways are considered: distributed pyrolytic pathway with external hydrogen production (from natural gas) and integrated pyrolytic pathway with internal hydrogen production (from pyrolytic oil). and are compared to a conventionally produced diesel pathway. The results of the analysis reveal that integrated-internal pyrolytic diesel pathway has lowest resources consumption and lowest pollutant emissions. Compared to conventionally produced diesel, integrated-internal pyrolysis pathway consumes 80% less of fossil fuels, and 92% more of renewables, has 90% lower global warming potential, 30% lower terrestrial acidification potential but 38% higher particulate matter formation potential. Compared to the distributed-external pathway, 88% less fossil fuels, and 36% less renewables are consumed in the integrated-internal pathway, global warming potential is 97% lower, terrestrial acidification is 20% lower, and particulate matter formation is 49% lower. Nevertheless, this pathway has high coal and hydroelectrical power consumption due to electricity production and high emissions of particulate matter, CO2, SOx, and N2O. Another drawback of this production pathway is the low yield of diesel obtained (38% lower than in distributed-external pathway). With this regard, it is still hard to designate production of diesel from fast pyrolysis of Miscanthus as a more environmentally friendly replacement of the conventional production diesel pathway.

AB  - Thermal behavior of a building is mostly determined by type and capacity of utilized insulation material. Synthetic and other conventional mass-produced insulations are largely efficient in their primary role of decreasing heat flow through building envelope, but their dynamic thermal behavior and overall environmental footprint are frequently worse than those of biomass based materials. Diverse efforts towards development of energy efficient but sustainable biomass insulation have been made. The analysis of thermal performance by steady-state and transient boundary conditions and Life Cycle Assessment of biomass insulation materials, recommend them as life-time energy efficient and resource-saving alternative to conventional thermal insulations.

AB  - Following the guiding "3R" principle of sustainable development (Reduce, Reuse and Recycle), the potential applicability concerning various components of construction and demolition waste (C&DW) was investigated for radionuclide sorption (Sr, Co, Ni). Collected samples of waste concrete, facade, bricks and asphalt were characterized in respect to mineralogical and surface composition, pH and radioactivity, while their sorption capacities were determined in batch conditions. Selectivity of potential sorbents differed in respect to Co2+ and Ni2+ ions, whereas sorption of Sr2+ was generally low. Concrete and facade have demonstrated both: the highest sorption capacities and the strongest interaction with the investigated cations, as revealed by sequential extraction analysis of loaded sorbents. Taking into account chemical compatibility with mixtures, commonly used for the solidification of radioactive waste, and expressed high affinity for studied cations, waste cement materials and debris are promising matrices for radionuclide immobilization.

The sample was properly characterized in terms of mineralogical and surface composition, particles morphology, radioactivity, and of the behavior in aqueous solutions at different solid/liquid ratios and pH values. Since radioactive isotopes of Sr, Co and Ni are significant components of the liquid radioactive waste, sequestering of their ions from aqueous media was studied in single and multi-component batch sorption systems. The capacity of waste concrete decreased in the order Ni2+ (0.54 mmol/g) > Co2+ (0.32 mmol/g) > Sr2+ (0.25 mmol/g). Concurrent sorption was analyzed using Simplex Centroid Experimental Design and the coefficients that correspond to the linear and interaction terms were obtained using a special cubic model.

This is a brand new cost-effective, environment-friendly and energy-efficient material. In order to increase energy efficiency and resource saving, the lime and fly ash were used instead of cement binder. Two different mixtures were made, one with lime and one with lime and fly ash. The mixture with lime and fly ash showed the higher values of compressive and bending strength. It can be concluded that addition of fly ash contributes to mechanical properties of this new material.

AB  - A novel, cost-effective, ecological and energy-efficient insulation material based on Miscanthus x Giganteus with a reduced cement binder amount enriched with a smaller quantity of zeolite has been examined. In order to increase energy efficiency, the use of cement was minimized, as it is considered an extremely energy-inefficient material whose production requires large amounts of thermal energy, accompanied with high carbon dioxide emissions. As the physical-mechanical properties of thermal insulation are of crucial importance the paper deals with physical-mechanical properties of this material. The experimental part was consisted of preparation of four mixtures with different component mass ratio, and determination of their physical-mechanical properties. The sample that showed the highest values of compressive and bending strength simultaneously was subjected to steady state conditions thermal conductivity testing.

AB  - This paper investigates the environmental impacts and energy benefits of the cultivation of Miscanthus (Miscanthus x giganteus Greef et Deu.), in order to initiate its use in sustainable household heating in the Republic of Serbia. Based on the analysis of available data regarding the use of agricultural machinery in Serbia, a Miscanthus supply chain is constructed and examined in detail, scrutinizing all relevant operationsfrom planting of rhizomes to thermal energy production. Results of the life cycle assessment identify the briquetting process as the most environmentally burdensome operation due to high electricity consumption and low productivity. It is concluded that an average yield of 23.5 t dry matter (d.m.) year(-1) obtained from 1 ha of chernozem soil would have energy output:energy input (EO:EI) ratio of 51:1, and would release 365.5 gigajoules (GJ) of heat during combustion in a boiler. With this amount of energy, around 383 m(2) of a free-standing family house in Serbia can be heated annually. The same amount of energy is obtained by the combustion of 22 t of lignite or 23 t of wood logs. The substitution of lignite and wood with Miscanthus briquettes would lead to significant reduction of CO2 equivalents (eq), SO2 eq, P eq, N eq, 1,4 dichlorobenzene (1,4-DB) eq, Non-methane volatile organic compound (NMVOC), PM10 eq and U235 eq emissions. This designates Miscanthus as a more sustainable energy solution for household heating. In instances where more modern agricultural machinery is used, emission reduction is higher, except for CO2 eq due to higher emission factors predicted for more powerful engines. Depending on Miscanthus' annual yield, the replacement of set-aside land with Miscanthus plantations result in carbon (C) sequestration from 0.08 t C ha(-1) year(-1) to 0.91 t C ha(-1) year(-1). In a modern machinery scenario, C sequestration is only attainable when maximal Miscanthus yield is obtained. The combined use of machinery with different engine power is the best option for Miscanthus cultivation in Serbia.

AB  - This paper presents energy recovery data by hazardous waste treatment in the Republic of Serbia (RS). Such waste treatment meets modern requirements of environmental protection, by reducing waste and increasing energy use from alternative sources. From a total of 210.000 tons of hazardous waste generated in the RS, only 4.300 tons is utilized as an energy source. Quantity and contribution data of hazardous waste fractions for energy recovery by its treatment in the RS in 2014, shows that only two categories of hazardous waste („waste containing oil“ and „oil from oil/water separator“) are treated in a satisfying manner, though in insufficient quantities.

AB  - The possible utilization of waste ceramic (CT) and roof tiles (RT), as sorbents for liquid radioactive waste (LRW) treatment, was investigated. Following the European directives on waste and politics of saving natural raw materials, it is reasonable and desirable to explore potential applicability of such construction wastes. These materials are lowcost and locally available in high quantities, yet, their sorption characteristics were not evaluated to this point. In the present study, detailed physicochemical characterization of waste CT and RT included determination of mineral composition, surface functional groups, radioactivity, as well as the stability in aqueous media. The batch sorption study of Sr2+, Co2+ and Ni2+ ions from single- and multi-component solutions was performed, as their radioactive isotopes are common constituents in LRW. Sorption equilibrium was best described by Freundlich isotherm model, regardless of the sorbent and the sorbate type. Sorption capacities of CT, defined in single element solutions, increased in the order 0.035 mmol Sr/g  lt  0.12 mmol Ni/g  lt  0.17 mmol Co/g, while the affinity of RT was generally lower (0.030 mmol Sr/g  lt 0.065 mmol Co/g  lt  0.10 mmolNi/g). The study of competitive cation sorption was performed following a simplex centroid experimental design matrix. The equations for the prediction of metal sorption capacities from multi-component solution were derived. Utilization of CT and RT might be an efficient way for waste water purification, with simultaneous reduction in construction waste amount on municipal landfills.

AB  - The paper presents results of an experimental investigation of convective drying of apples var. Idared, potatoes var. Desiree and bananas var. Grand Nein, in full recirculation laboratory-scale dryer. The experiments were conducted with cube-shaped apple samples (side length 10 and 13mm), potato chips (slice thickness 2 and 3mm) and banana cylinders (slice thickness 6 and 7mm), without pre-treatment. The drying experiment was conducted at fully controlled air temperature (35-45-55 degrees C), relative humidity (10-20-30%) and air velocity (1-1.5-2m/s). Results are discussed through their comparison with other heat pump drying system scenarios in order to find the most efficient one. The efficiency of the heat pump drying (HPD) system was analyzed using the several indicators: specific moisture extraction rate (SMER), specific energy consumption (SEC), heat pump dryer efficiency (HPDE) and moisture extraction rate (MER). The average values of the full air recirculation HPD system efficiency indicators were obtained in range: SMERHP=0.030-1.317kg/kWh, SMERHPD=0.047-0.651kg/kWh, SEC=0.211-9.358 MJ/kg, HPDE=0.426-20.7 MJ/kg and MER=1.362-17.194 kWh/kg. The results were evaluated in order to provide better information about the benefits of full air recirculation usage in HPD systems in regards to the other similar dryer configurations. Practical ApplicationsThis study uses full air recirculation to provide better control of the main drying parameters and to minimize impact of the surroundings. The novelty of this study lies in the fact that RH of the drying air was precisely controlled during all experiments. The evaluation of the relevance of full air recirculation HPD system is rare in literature and therefore the present study is directed toward quantification of influence of HPD system configuration on drying process efficiency. Dependence of several energy efficiency indicators of HPD system performance: SMER, SEC, HPDE and MER on HPD system air recirculation rate were investigated. The results were evaluated in order to provide better information about the benefits of full air recirculation usage in HPD systems in regards to the other similar dryer configurations.

AB  - U radu su predstavljeni podaci o generisanju, količinama i upravljanju medicinskim otpadom (MO) u
Srbiji. Predstavljeni su načini procene i ukupne godišnje količine generisanja MO po kategorijama.
Zaključeno je da se najviše proizvede farmaceutskog (64%) i infektivnog (32%) MO. Prema dobijenim
podacima, upravljanje MO u Srbiji je trenutno na niskom nivou, osim kada je u pitanju infektivni otpad.
U radu su predložene jednostavnije metode tretmana u postojećim autoklavima i kompleksnije metode
(insineracija i plazmena piroliza), kao kratkoročna i dugoročna rešenja. Predviđena rastuća količina
MO zahteva povećanje postojećih kapaciteta prerade i primenu novih rešenja. Kapacitet instaliranih

glavne frakcije čine farmaceutski i hemijski otpad ne postoji infrastruktura. Kao privremeno rešenje,
farmaceutski otpad se tretira u inostranstvu što na duži vremenski period nije finansijski prihvatljivo.

preporuka je da se ovoj mreži pridruže i dodatni kapaciteti za tretman neinfektivnog otpada, uz

abstract = "U radu su predstavljeni podaci o generisanju, količinama i upravljanju medicinskim otpadom (MO) u
Srbiji. Predstavljeni su načini procene i ukupne godišnje količine generisanja MO po kategorijama.
Zaključeno je da se najviše proizvede farmaceutskog (64%) i infektivnog (32%) MO. Prema dobijenim
podacima, upravljanje MO u Srbiji je trenutno na niskom nivou, osim kada je u pitanju infektivni otpad.
U radu su predložene jednostavnije metode tretmana u postojećim autoklavima i kompleksnije metode
(insineracija i plazmena piroliza), kao kratkoročna i dugoročna rešenja. Predviđena rastuća količina
MO zahteva povećanje postojećih kapaciteta prerade i primenu novih rešenja. Kapacitet instaliranih
autoklava može da bude uvećan povećanjem njihovog radnog vremena, kako bi se izbegla dodatna
ulaganja. Međutim, tretman u autoklavima je pogodan samo za infektivni otpad. Za drugi MO, čije

AB  - This paper aims to highlight the advantages of using Life Cycle Assessment (or LCA) tool in energy sector for rational energy consumption, selection of green technologies and process optimization. Besides the definition and description of basic principles of this method and its historical development, previous examples of worldwide applications are analyzed. Review of these examples is made on the basis of a critical analysis of the available literature regarding the application of LCA for sustainable production of electricity and heat. Trend of using this tool since its inception until now is rising, together with a greater interest of general public to reduce negative impacts on the environment during production, use and disposal of various products. Compared to other countries (EU and beyond), in Serbia the LCA tool is insufficiently studied and practically unused. With this regard, special emphasis is placed on the possibility of practicing LCA in terms of proving the environmental suitability of biomass as an energy source, considering its huge potential in the Republic of Serbia. Wider utilization of LCA approach would also enable investigation and assessment of possibilities for heat production by different renewable energy sources in order to identify optimized environmental solutions for Serbian energy sector and to decrease dependence on energy imports through increased reliance on domestic energy resources.

AB  - Precise understanding of heat transfer processes inside the latent thermal energy storage exposed to different initial and boundary conditions is crucial for development of optimized design and operating features of similar devices. The paper presents 3D numerical study of phase change material heat storage in the shape of vertical cylinder reservoir with axially placed heat source/sink equipped with variable number of conductance enhancing longitudinal rectangular fins. As the principally important observed is the case of vertically variable heat flux supplied to the phase change material during the melting process. The numerical modeling is based on the physical model of the process and is being carried out by Fluent software that uses finite volume method for solving continuity, momentum and energy equations. The coupling between pressure and velocity is based on the Semi- Implicit Pressure- Linked Equation (SIMPLE) algorithm. The results of numerical simulations are verified through the comparison with the own experimental results. Exemplary results for characteristic heat storage geometries and boundary conditions are presented and analyzed in the paper.

AB  - Enhancement of heat transfer over a cylinder shaped thermal energy storage filled by paraffin E53 by use of longitudinal rectangular copper fins was analyzed. The thermo-physical features of the storage material are determined in separate experiments and implemented to FLUENT software over user defined function. Advanced thermal storage geometry comprehension and optimization required introduction of a parameter suitable for the analysis of heat transfer enhancement, so the ratio of heat transfer surfaces as a factor was proposed and applied. It is revealed that increase of the ratio of heat transfer surfaces leads to the decrease of melting time and vice versa. Numerical analysis, employing the 3-D model built in Ansys software, observed storage reservoir geometries with variable number of longitudinal fins. The adjusted set of boundary conditions was carried out and both written in C language and implemented over user defined function in order to define variable heat flux along the height of the heater. The comparison of acquired numerical and experimental results showed a strong correlation. Experimental validation of numerical results was done on the real thermal energy storage apparatus.

AB  - Osnovu rešenja koje omogućava bolje iskorišćavanje otpadne toplote otparka i sprečava gubitak hemijski pripremljene tople predstavlja dobošasti razmenjivač toplote – kondenzator otparka. Uređaj je konstruisan sa nepokretnim cevnim pločama i sa suprotnosmernim tokom fluida. Izrađen je od nerđajućeg čelika AISI 316. Rashladna voda struji u jednom prolazu kroz cevi koje su u trouglastom rasporedu. Otparak prirodnim konvektivnim strujanjem sa gornje strane rezetvoara kondenzata ulazi u međucevni prostor razmenjivača, gde se kondenzuje, a kondenzat se vraća u rezervoar kondezata sa suprotne strane razmenjivača. Međucevni prostor je bez cevnih pregrada, radi pospešivanja strujanja. Zahvaljujući modularnoj konstrukciji, predloženi uređaj je flekivilan u pogledu dimenzija i nazivne toplotne snage, te primenjiv u spektru parno-kotlovskih postrojenja.
