AB  - Agro-industrial waste has gained special attention as an abundatly available natural carbon source, which can be used for value-added products such as generating power, biofuel, biogas and biofertilizers production. Further application of agro-industrial waste may be as a substrate for solid state fermentation for production of antibiotics, enzymes, and phytochemicals. Isolation of enzymes from waste material as crude extracts contributes to the concept of sustainability and lowers their cost significantly. The enzyme of interest in this study was peroxidase isolated from soybean hull. Furthermore, the crude peroxidase from soybean hull was crosslinked by oxidized pectin onto the inner walls of PTFE microtubular reactor. The influence of the crosslinker concentration on the enzyme activity and crosslinking efficiency was evaluated, together with the effect of the reagents flow rate on the enzyme activity and crosslinking efficiency. Two different microtubular diameters were examined for the crude peroxidase crosslinking: 0.5 and 0.8 mm. After the immobilization, the possibility of anthraquinone dye removal by crosslinked peroxidase in the microtubular reactor was examined. The reusability of the immobilized enzyme was also evaluated in this study.

AB  - Wastewater from textile industry contains considerable amount of dissolved dye that can trigger environmental issues if is not treated properly. Numerous methods have been developed to degrade recalcitrant pollutants safely and utterly. Among them, enzymatic treatment of wastewater is gaining attention due to the enzyme’s specificity, easier manipulation, and generation of less toxic by-products. Still, the cost of enzymatic systems is the main limitation keeping the biocatalysts at lab-scale. Alternative solution for reducing the cost of enzymatic reaction systems is the use of microfluidic systems, which contribute to better mixing, process intensification and cleaner production. In this study, implementation of horseradish peroxidase for removal of the textile dye Acid Violet 109 is performed in a microfluidic reactor. The microreactor consists of three plunger pump units, two mixers and PTFE tube. The process parameters: residence time, dye, hydrogen peroxide, enzyme activity, the reactors’ diameter and length were optimized. Under the optimal process conditions: 30 mg/L dye concentration, 0.8 U/mL horseradish peroxidase activity, 0.1 mM hydrogen peroxide, 0.25 mm reactor's diameter, 97,3 % removal was achieved at residence time of 6 min. The results from this study show that enzymatic microfluidic reactors are a convenient technology for dye removal.

AB  - Predmetni pronalazak se odnosi na postupak biodegradacije antrahinonske boje Acid Violet 109 peroksidazom, izolovanom iz poljoprivrednog otpada u kontinualnom mikroreaktorskom sistemu. Postupak se sastoji od ekstrakcije enzima i biodegradacije boje u mikroreaktoru. Koncentracija boje treba da bude do 450 mg/L, enzimski ekstrakt aktivnosti 1 U/mL i vodonik-peroksid koncentracije do 1 mM, da bi se postigao najveći stepen biodegradacije. Na ovaj način dobija se visoko efikasan postupak biodegradacije antrahinonskih boja (~97 %) koji je održiv, ekološki i ekonomski opravdan.

AB  - Climate change projections indicate that Republic of Serbia and the Western Balkans will
face a high probability of continuing temperature increases, climatic extremes are projected to become
more common, including a significant increase in the number of extreme heat events. Heavier
precipitation events are expected in the winter months, whilst summers are projected to become even
drier. This paper aims to analyse effect of precipitation changes on landfill gas generation on the
Vinča landfill, the biggest landfill in Serbia. Quantities of generated landfill gas and methane have
been estimated by using LandGem model. Site specific methane generation rate has been calculated
according to GMI methodology for Central Eastern Europe. Sensitivity analyses is performed to
determine influence of a precipitation regimes on the methane generation rate on the site. Any increase
in precipitation (in range 10-30%) may increase landfill gas production for 4.3%. The paper shows
the difference in gas emissions, with the same composition of waste, and different precipitation
regimes. Changes in precipitation regimes due to climate change can affect the dynamics of landfill
gas emissions. This information is significant for the possible re-circulation of leachate from the
landfill which could result in an increased production of landfill gas.

AB  - Enzyme immobilization is a convenient technique for reuse of enzymes –it is one of the advantages that contributes for enhanced productivity and efficacy of these processes. Enzyme stability and their recovery from a reaction mixture are just a couple of the many benefits that can be acquired by immobilization [1]. These features give opportunity for enzymatic application at industrial scale. The enzyme used in this study is perox-idase, an oxidoreductase that oxidizes variety of organic pollutants such as: phenols, textile dyes and phar-maceutically active compounds[2]. The use of potato peel as a source of peroxidase for degradation of textile dye contributes to the  sustainability  of the treatment. The simple isolation of peroxidase as  a crude extract adds up to the cost effectiveness of the product (peroxidase).Given the fact that peroxidase is an eco-friendly biocatalyst, an effort is made to find a suitable ‘green’ way of immobilization. Glutaraldehyde is the most common cross-linker used for the same kind of immobilization [3]. However, it is a toxic compound, so it is replaced by alternative compounds such as natural polysaccharides. One of them is pectin that can be oxidized in order to introduce aldehyde groups, which in turn react with the amino-groups from the amino-acid residues and form Schiff bases [4], [5]. Afterwards, the cross-linked peroxidase can be applied for oxidation reaction.In this study, peroxidase was isolated from waste material –potato peel as a crude extract. The enzy-matic crude extract was precipitated with different reagents, in order to find the most suitable one. Next, the influence of the cross-linker concentration was examined. The cross-linked potato peel peroxidase was used for  biodegradation  of  the  anthraquinone  dye  Acid  Violet  109.  The  process  parameters:  pH,  reaction  time, enzyme, hydrogen peroxide and dye concentration were optimized for achieving the maximal degradation rate. The operational stability, as a key parameter in immobilized systems was also examined.

AB  - Despite the obvious benefits from mass production such as an increased productivity, lower product cost and rapid evolution, nowadays we are dealing with energy consumption issues and pollution. The generated waste poses a threat to the environment, so new green techniques are developed constantly. Waste valorization is one of the trending concepts that is a part of sustainability strategies. Potato exploitation due to mass production of chips, hash browns, frozen food and starch leads to a formation of high waste load. There are several available ways for potato peel valorization: as a biofertilizer, as a substrate for microbial growth, as an adsorbent, for extraction of antioxidants and for extraction of enzymes. The enzyme peroxidase is abundant in potato peel. This enzyme uses hydrogen peroxide as an activator and can be readily used for oxidation of different compounds - pollutants. In this study, peroxidase was isolated from potato peel and immobilized as cross-linked enzyme aggregates. Pectin was used as a green cross-linker. The immobilized potato peel peroxidase was used for degradation of a textile anthraquinone dye Lanaset Violet B. Under the optimal process parameters: pH 3, 0.4 mM hydrogen peroxide, 0.8 μmol/min CLEA peroxidase, 10 mg/L dye and 70 min, 85.71±1.45 % dye degradation was achieved. The operational stability, as a key parameter for immobilized enzyme systems, was also examined. After 4 cycles CLEA peroxidase kept 31.57±1.79 % of its biodegradation efficiency.

AB  - Landfilling is a dominant method of waste management in most developing countries. Moreover, a significant quantity of waste has been disposed on open dumps and unmanaged disposal sites. Landfill gas (LFG) can be considerable source of GHG emissions, as it consists of 50 % methane and 50 % carbon dioxide. Republic of Serbia is a developing country. Its waste management legislation is based on EU legislation. In the first decade of 2000s a set of laws was passed in this area. Unfortunately, the majority of goals were not fulfilled. An updated version of Waste management program is active since 2022. In Serbia, 2.95 million tons of waste is generated every year. It is estimated that 15-20 % is disposed on dumps, while 80 % is collected and disposed on the landfills. Waste treatment does not exist. Recycling rate is a very low, around 15%. Different waste management scenarios of impact on GHG emissions have been analysed. The analysis was performed using the software "Tool for Calculating Greenhouse Gases (GHG) in Solid Waste Management (SWM-GHG calculator)"developed by the German IFEU (ger. Institut für Energie- und Umweltforschung Heidelberg). The base scenario describes the current situation. Scenarios 1 and 2 describe goals set for 2025 and 2030 by Waste management program in the Republic of Serbia for the period 2022 - 2031. Scenario 3 describes best case scenario, with fully functional modern waste management system. The analysis includes several parameters, such as landfill type, recycling rate, LFG collection efficiency and use of waste incineration technology.

AB  - Waste disposal is the last but inevitable step in waste management and it significantly effects the environment. According to the Serbian Waste Management Strategy, disposal sites should be closed and new, sanitary regional landfills should be established. In this paper, case study method has been used to analyse technical regulations in order to determine the need for more detailed elaboration of the Best available technique (BAT) for landfill closure. Based on the analyses results, a number of proposals have been formulated and elaborated aimed to ensure pollution prevention and environment protection on the old and new landfills. A new national model for improvement BAT landfills closure is proposed. Proposed BAT improvements for landfill cover might be used on the international level, because many countries do not have BAT elaborations beside the Landfill Directive.

abstract = "Waste disposal is the last but inevitable step in waste management and it significantly effects the environment. According to the Serbian Waste Management Strategy, disposal sites should be closed and new, sanitary regional landfills should be established. In this paper, case study method has been used to analyse technical regulations in order to determine the need for more detailed elaboration of the Best available technique (BAT) for landfill closure. Based on the analyses results, a number of proposals have been formulated and elaborated aimed to ensure pollution prevention and environment protection on the old and new landfills. A new national model for improvement BAT landfills closure is proposed. Proposed BAT improvements for landfill cover might be used on the international level, because many countries do not have BAT elaborations beside the Landfill Directive.",

AB  - Aromatic heterocyclic compounds containing nitrogen in their structure have attracted
considerable interest in medicine, because of their certain pharmacological properties
including anticancer, anti-inflammatory, antihypertensive, antibacterial, antifungal and
antiviral activities. Among them, derivatives with 2-pyridone moiety are particularly
notable due to their wide application in pharmacological and dye industry. A usual
procedure for synthesis of 2-pyridone moiety is classic condensation reaction of 1,3-
dicarbonyl compounds with cyanoacetamide. However, in the case of various
substituted reactants, drawback of this reaction can be a low yield of desirable products
and long reaction time. This factor has led to the development of different methods for
synthesis in order to overcome these defects. The microreactor technology and flow
chemistry could play a significant role in the improving of organic synthesis efficiency.
The microreactor approach could provide enhanced productivity, fast conversion and
altogether less hazardous chemical synthesis. Furthermore, it pushes towards designing
of chemistry with a lower environmental and economic impact. In this study the
synthesis of 2-pyridone moiety in a continuous flow coil-type microreactor system was
examined. In order to optimize reaction conditions, flow rates of starting reagents were
varied. The desirable 2-pyridone was obtained in satisfactory yield of circa 60% in less
than 10 minutes. The structure and purity of synthetized 2-pyridone moiety were
confirmed by melting point, FT-IR, 1
H NMR and UV-Vis spectra. The efficiency of the
presented method for the synthesis of 2-pyridone based molecules has promising scaleup potential.

AB  - In the industry, wastewater is important environmental problem. Due to the growing
environmental concern this problem became one of key issues. Large amounts of highly
contaminated wastewater, as consequence of industrial use, are important environmental
polluters. Before discharging, wastewater has to be treated to achieve quality prescribed
by law. One of solutions could be decomposition of pollutants. The decomposition of
pollutants from industrial wastewaters is of critical importance in order to maintain a
clean environment. Many process commonly used in polluter degradation processes
commonly use different harmful chemicals or leads to formation of potentially harmful
byproducts. Treatment of wastewater from industry in microreactor system is new
ecological solution. Over the last few decades microreactors have been increasingly
recognized as being an alternative to conventional batch reactors in chemical industry.
Application of these systems have aim to transform conventional into more productive
and environmental friendlier process. They are characterized by micrometer dimensions
and continuous mode, resulting in significant intensification of the mass and heat
transfer. Microreactor systems are already find application in chemical industry,
biotechnology, pharmaceutical industry and medicine. Decomposition of pollutants in
wastewater is complex, but microreactors allow purification with low quantities of
chemical reagents. This paper represents review of possible fields of wastewater

AB  - Wastewater treatment is one of the most analysed issue in theory and practice because
of its current and vast significance nowadays. Wide range of chemical, physical and
biochemical processes are developed for wastewater treatment. Although biochemical
processes are the most eco-friendly when compared to chemical and physical, they are
still not the leading type of technology in this field. In recent years, microreactors are
trending because of their particular characteristics that can be utilized in numerous
areas. Continuous flow, higher reaction yields, scale independant and high selectivity
are just a few of the beneficial characteristics of microreactors. Due to the micro
channels, turbulent flow regime is avoided. Furthermore, high surface-to-area ratios aid
in far greater and faster heat and mass transfer than in common reactors. Another asset
of microreactors is short diffusion pathways, that together with small reaction pathways
add to its favorable attributes. When it comes to enzymes, due to their small size and
mild reaction conditions requirements, they are ideal for working in microreactos.
Enzymes can be isolated from different sources, but isolation from plant waste material
is what makes them even more interesting. Because of the above mentioned
microreactor’s pros, several enzyme’s disadvantagious properties are overcome. In this
study, a review of the positive characteristic of enzyme microreators in wastwater
treatment will be discussed.

AB  - Dyes are an important class of pollutants because large amounts are often found in the environment as a result of their extensive industrial use. Traditional wastewater treatment methods often lead to high energy costs, formation of by-products, and the production of sludge. This paper analyzes the possibility of using a new, sustainable approach to water decolorization with reduced consumption of chemicals. In microreactor experiments, reactant molar ratios, volumetric flow rate, and microreactor length and diameter were varied. The obtained results showed that batch decolorization required 250-500 times higher molar ratios to achieve comparable decolorization (70-90%) and at least three times longer residence time. Microreactor experiments demonstrated that higher microreactor lengths and molar ratios influence positively the decolorization process, although satisfactory results are also achieved with medium microreactor lengths and lower molar ratios. Higher fluids velocities contribute to the decolorization process, but the best results were obtained using a medium velocity (in a 5.8m microreactor system) to achieve the highest possible mixing intensity and long enough residence time. Microreactor systems have achieved significantly better decolorization results, considering any combination of microreactor length, molar ratio, diameter, flow rate, and residence time, than a batch system. Thus, a medium length microreactor system, with a low concentration of NaOCl, low flow rate, small diameter, and medium residence time can achieve satisfactory decolorization results, but with a lower consumption of chemicals, energy, equipment, and better environmental impact. Article HighlightsColored wastewater was decolorized using batch and microreactor systems.Various microreactor lengths, diameters, and mixture velocities were tested.Microreactor system required 500 times lower amounts of decolorizing agent.

AB  - This paper deals with environmental policy issues related to a landfill design. The final product of numerous waste treatments should be placed on a landfill. Before waste disposal, the ground should be protected by a mineral layer with properties required by the related regulation. In order to prevent environment pollution, EU adopted the Landfill Directive 1999/31/EC. The most important technical requirements related to the characteristics of the layer material are water permeability and thickness. The performed comparative national regulatory analysis raised the question of the need for more uniform elaboration of the directive requirements over the whole European Union area (including EU candidates). The choice of the material for the impermeable mineral layer, which should be made during landfill design, is a very important decision. Methods for the determination of the permeability coefficient were analysed, showing that the Directive should define hydraulic gradient as a physical quantity and define its value through measurement of the permeability coefficient. The paper analyses whether some parts of the Directive, as landfill design BAT and base for national legislative acts, require further elaboration in order to provide sufficient information about proper protection of soil and water. Using integrated approach, seven amendments on the directive annex I were suggested related to (a) the meaning of the term artificially established geological barrier, (b) layer thickness,

AB  - Waste disposal is an important element of integrated waste management. In order to dispose of waste that is free of environmental risk, the proper design of landfills during their construction and/or closure is necessary. The first section of the paper presents the current state of landfills in Serbia, the second deals with problems in project design of landfills, especially in regard to their: a) program of waste disposal; b) impermeable layer; c) leaching collection and treatment; and d) gas collection and treatment. Analysis shows that many modern landfills in Serbia do not meet environmental protection requirements, therefore, they need reconstruction. All existing landfills owned by municipalities, as well as illegal dump sites, should be adequately closed. This paper presents the guidelines for successful landfill design which are to serve to meet the requirements and recommendations of Serbian and European regulations. Sound design of landfill technological elements should insure full sustainability of landfills in Serbia.
AB  - Deponovanje otpada je element integrisanog upravljanja otpadom. Valjano izrađeni projekti izgradnje i/ili zatvaranja deponije osiguravaju bezbedno odlaganje otpada, uz minimalne negativne uticaje na životnu sredinu. U prvom delu rada izvršen je pregled i analiza deponija u Republici Srbiji. U drugom delu rada, u funkciji analize, opisani su značajni elementi tehnološkog projektovanja savremenih deponija koji uključuju: a) program deponovanja, b) obezbeđivanje vodonepropusnosti dna i prekrivnog sloja, c) sakupljanje i tretman procednih voda i d) sakupljanje, tretman i iskorišćenje deponijskog gasa. U radu je konstatovano da postojeće, savremene deponije nisu u potpunosti projektovane u skladu sa propisima, te da je neophodna njihova rekonstrukcija. Takođe, postojeća smetilišta i divlje deponije neophodno je zatvoriti i sanirati. U ovom radu predstavljene su smernice za valjano tehnološko projektovanje deponija koje su u funkciji ispunjavanja zahteva i preporuka nacionalnih i evropskih propisa.

AB  - Storage of crude oil and petroleum products inevitably leads to evaporative losses. Those losses are important for the industrial plants mass balances, as well as for the environmental protection. In this paper, estimation of evaporative losses was performed using software program TANKS 409d which was developed by the Agency for Environmental Protection of the United States US EPA. Emissions were estimated for the following types of storage tanks: fixed conical roof tank, fixed dome roof tank, external floating roof tank, internal floating roof tank and domed external floating roof tank. Obtained results show quantities of evaporated losses per tone of stored liquid. Crude oil fixed roof storage tank losses are cca. 0.5 kg per tone of crude oil. For floating roof, crude oil losses are 0.001 kg/t. Fuel oil (diesel fuel and heating oil) have the smallest evaporation losses, which are in order of magnitude 10-3 kg/tone. Liquids with higher Reid Vapor Pressure have very high evaporative losses for tanks with fixed roof, up to 2.07 kg/tone. In case of external floating roof tank, losses are 0.32 kg/tone. The smallest losses are for internal floating roof tank and domed external floating roof tank: 0.072 and 0.044, respectively. Finally, it can be concluded that the liquid with low volatility of low BTEX amount can be stored in tanks with fixed roof. In this case, the prevailing economic aspect, because the total amount of evaporative loss does not significantly affect the environment. On the other hand, storage of volatile derivatives with high levels of BTEX is not justified from the economic point of view or from the standpoint of the environment protection.
AB  - Skladištenje nafte i naftnih derivata neizbežno dovodi do pojave evaporativnih gubitaka, koji su važni sa stanovišta odgovarajućeg bilansa i sa stanovišta zaštite životne sredine. U radu je izvršena kvantifikacija evaporativnih gubitaka za različite tipove komercijalnih rezervoara sa fiksnim i plivajućim krovovima korišćenjem softverskog programa TANKS 409d. Na osnovu rezultata procenjene su mase evaporativnih gubitaka po toni uskladištene tečnosti. Gubici sirove nafte za rezervaore sa fiksnim krovom iznose oko 0,5 kg/t sirove nafte, a za rezervoare sa plutajućim krovom oko 0,001 kg/t. Gubici dizela i mazuta su zanemarljivo mali, iznose do 10-3 kg/t. Najznačajniji gubici isparljivih tečnosti su u rezervoarima sa fiksnim krovom (do 2,07 kg/t), a najmanji gubici su kod rezervoara sa kupolastim krovom (oko 0,004 kg/t).
