AB  - In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to those achieved within classical syntheses. In order to optimize the continuous flow syntheses and increase the yield of the products, the retention time in the microreactor was varied by changing the flow rates of the reactant solutions. Furthermore, the reaction was optimized for 3-cyano-4,6-dimethyl-2-pyridone and 3-cyano-6-hydroxy-4-methyl-2-pyridone, which are comercially important in the pharmaceutical and dye industries. Both 2-pyridones were obtained in satisfactory yield of circa 60 % in less than 10 min. The resulting compounds were characterized by their melting points, FT-IR, H-1-NMR and UV-Vis spectra. The efficiency of the presented method for the synthesis of 2-pyridone-based molecules has promising potential for industrial production.

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 research focuses on the modeling of the liquid-liquid dispersed system, including particular insight on the electrocoalescence (EC) process that occurs during the breaking of double emulsions. The representative system, used in this work, was taken from the pilot plant for solvent extraction of uranium from wet phosphoric acid. The chosen framework required for elucidation of the EC process is based on the electrohydrodynamic (EHD) principles. During the model development it was necessary to consider several theoretical concepts for easier understanding and description of the related events. The first is the concept of entities, and corresponding classification of finely dispersed systems. The second concept is an introduction of almost forgotten basic electrodynamics element the memdiode or memristor as a current controlled device, and corresponding memristive systems. Hence, the conclusions that may be withdrawn from the presented results and findings could enable easier designing of the solutions for a breaking of double emulsions problems, that is, the entrainment problems that may arise in some pilot or industrial plants. Finally, the perspectives and the remaining challenges, considering the here discussed concepts and model based on the EHD principles, are mentioned.

AB  - The aim of this paper was to emphasise the need for a volatile organic compounds VOC policy review in the field of river barge transportation of petrochemicals. Review of the VOC policy shows that barges neither fall under an integrated pollution prevention and control permit nor any other regulation or incentive related environmental policy. Current situation and trend in this area is presented through a case study of the Danube River, Serbia. The case study shows that evaporative losses have increased c ca 22 times in period 2006-2010 and, that vapour collection system can reduce VOC emissions by up to 3 times. A proposal for improved VOC policy has been developed in detail based on the following elements: a) The appropriate Best Available Techniques reference document (BREF) should include the transport sector; b) Mandatory reporting of VOC emitted during barge transport of crude oil and crude oil derivates should be introduced, and c) A pollution charge should be introduced on all barges without vapour collection system installed "onboard". Three potential scenarios for the VOC charge are presented, which vary according to the charge introducing dynamics. The differences between scenarios are in initial levels of charge, but the final charge is same for all three and it is proposed to be 220 (sic) per capacity ton.

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  - The aim of the article is to present a case study related to implementation of cleaner production (CP) process with the concept of minimizing emissions versus the end of pipe (EOP) approach within pharmaceutical industry. The idea is to move beyond simple pollution control by technology improvement and prevention of organic solvents emission into the atmosphere. Furthermore, cost-effectiveness of the suggested approach is evaluated compared to traditional concepts of polluted air treatment, ensuring both environmentally friendly and effective production of film coated tablets. Technological changes to improve the impact on the environment have been applied already in many industries as well as in pharmaceutical manufacturing. However, more effort is to be made in order to further decrease particularly VOCs emission into the atmosphere. An analysis is provided to stimulate a proactive approach in this field towards completely eliminating the use of organic solvents from film-coating systems in the production of the pharmaceutical solid dosage forms. The new way of addressing the costs actually associated with embracing cleaner technologies, which are mostly related to regulatory aspects in pharmaceutical industry, is aimed to promote the change in culture, as well as to be applied in the decision making process for other pharmaceutical facilities still using organic solvents based coatings in the manufacturing of tablets. The significance of the small scale projects is additionally emphasized considering the magnitude of the world generic market.

AB  - The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average monthly temperatures and the total monthly precipitations in the period from 2000 to 2010, and their deviations from the thirty year normal levels. The SWP operation is based on an ex-post price determination, and it conveys a signal to water users on resource scarcity. Not knowing ex ante how high their monthly bill is going to be, but aware of the price-setting rule, consumers will be in a situation to change their pattern of behaviour towards a more sustainable water use. Potential of the SWP model implementation are a) pushing consumers towards rationality, b) valuable resource conservation and c) enabling the water supply company to cover peak-season supply and the related costs. The SWP model has been created for the Belgrade Water and Wastewater Company, but might be easily implemented in all other cities with the same problems.

AB  - This article presents experience from the practice of a successful pharmaceutical company related to design and implementation of performance measures (PMs) for deviation management linked to the analysis of impact on the production cost for the selected product. Case study focuses on PMs within good manufacturing practice (GMP) processes related to quality assurance (QA) and quality management, with the aim of complying with its future requirements proposed by the European Commission. Critical areas were identified based on data gathered from the industrial deviation database. Implementation of the suggested corrective actions showed significant improvement in terms of reducing their number for more than 50% per selected deviation category. The results obtained in the course of this practice-oriented study contribute to further improvement of deviation management in the pharmaceutical industry and performance measurement of other GMP processes. The suggested performance measurement concept and problem-solving techniques may serve both practitioners and the decision-makers within QA and quality control (QC) in order to improve their processes by implementing relevant regulatory requirements for quality management and maintain compliance.

AB  - The photocatalytic degradation of the herbicide metamitron in water using ZnO under Osram ULTRA-VITALUX (R) lamp light was studied. The effect of the operational parameters such as initial concentration of catalyst, initial metamitron concentration, initial salt concentration (NaCl, Na2CO3 and Na2SO4) and pH was studied. The optimal concentration of catalyst was found to be 2.0 g/l. First-order rate constants were calculated for the uncatalysed reactions. On the base of the Langmuir-Hinshelwood mechanism, a pseudo first-order kinetic model was illustrated and the adsorption equilibrium constant and the rate constant of the surface reaction were calculated (0.119 l mg(-1) and 0.836 mg l(-1) min(-1), respectively). The photodegradation rate was higher in acidic than in alkaline conditions. When salt effect was studied, it was found that sodium carbonate was the most powerful inhibitor used, while sodium chloride was the weakest one. A negligible inhibition was observed when the concentration of sodium chloride was 20 mM. The rate of photodecomposition of metamitron was measured using UV spectroscopy and HPLC, while its mineralization was followed using ion chromatography (IC), as well as total organic carbon (TOC) and total nitrogen (TN) analysis. Under the employed conditions, almost complete disappearance of 9 mg/ml of herbicide, 56% TOC and 34% TN removal, occurred within 4 h. The ion chromatography results showed that the mineralization led to ammonium, nitrite and nitrate ions during the process.

AB  - The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the current of the oxidation peak of pure azithromycin and azithromycin from Hemomycin (R) at 0.6 V versus SCE in 0.05 M NaHCO3 and in a mixture methanol -0.05 M NaHCO3 (1:1) at a scan rate of 50 mV s(-1) is a linear function of the concentration in the range of 0.235-0.588 mg/cm(3). HPLC analysis of the bulk of electrolyte confirmed the data obtained by analysis of the values of the current peak concerning the concentration of antibiotic in the investigated concentration range. The role of methanol, when present, is discussed. In the case of azithromycin, the presence of methanol leads to higher current peak values. However, in the case of Hemonlycin (R), methanol should be avoided because of its inhibiting influence on the qualitative and quantitative determination of azithromycin and on the azithromycin/lactose, separation.
