AB  - Peach stones, a valuable agro-industrial by-product available in many countries worldwide, comprise a renewable resource, which can be widely applied for multifunctional purposes. Its important advantages such as high-energy value, low ash content, low price and wide abundance, make peach stones an ideal fuel for energy production, but also for new materials synthesis. Although peach stones exhibit adequate combustion properties, allowing their direct use with minimal physical/chemical treatment, they often need further modification in order to improve their thermal properties, where slow pyrolysis is frequently used. This study aims to provide a practical and effective solution to the revalorization of waste biomass originating from the fruit processing industry, through slow pyrolysis in order to convert this waste into carbonaceous material - biochar. The thermo-chemical conversion of raw biomass resulted in a stable material with excellent fuel properties, with higher mass energy density and grinding ability, providing biochar with properties, in energy sense, similar or even better than a coal. Biochar has a higher fixed carbon content and a higher energy potential than biomass itself, and its application as a biofuel might reduce emissions of greenhouse gases, as it reduces the amount of waste landed and increases the share of energy generated from renewable sources.
AB  - Koštice breskve, otpadna biomasa poreklom iz industrije prerade voća, dostupna u mnogim zemljama širom sveta, predstavlja obnovljivi resurs koji može imati različitu primenu. Prednosti koje se ogledaju u velikom energetskom potencijalu, malom sadržaju pepela, niskoj ceni i širokoj rasprostranjenosti, čine koštice breskve idealnim resursom za proizvodnju energije, ali i za sintezu novih materijala. Iako koštice breskve imaju svojstva koja im omogućavaju da se koriste uz minimalni fizičkio-hemijski tretman, često im je potrebna dodatna modifikacija kako bi se poboljšala njihova svojstva. Jedan on načina poboljšanja energetskih karakteristika otpadne biomase predstavlja termohemijska konverzija materijala u vidu spore pirolize. Ispitivanja prikazana u ovom radu obavljena su sa ciljem obezbeđivanja praktičnog i efikasnog rešenje za revalorizaciju otpadne biomase koja potiče iz industrije prerade voća, putem spore pirolize kojom se vrši konverzija ovog otpada u ugljenični materijal – biočađ. Prikazani rezultati ukazuju na glavna svojstva dobijene biočađi u funkciji njene primene kao čvrstog goriva, istovremeno ih upoređujući sa svojstvima sirove biomase. Termohemijska konverzija polazne lignocelulozne biomase daje stabilni ugljenični material odličnih gorivih karakteristika, veće energetske gustine i boljih mehaničkih svojstava, što rezultuje energetskim svojstvima koja su bolja od uglja. Biočađ poseduje znatno veći energetski potencijal od same biomase, i njegova primena kao biogoriva može redukovati emisiju gasova sa efektom staklene baste, pri čemu se istovremeno smanjuje količina deponovanog otpada ali i povećava udeo energije generisane iz obnovljivih izvora.

AB  - In this study, slow pyrolysis was employed for the thermochemical conversion of peach stones (PS), lignocellulosic waste (LCW) from food industry, to prepare biochar (PS-B), a new and efficient sorbent for the removal of toxic dye, brilliant green (BG), from aqueous solution. Detailed characteristics of PS and PS-B were analysed using pH suspension, pHPZC, zeta potential, particle size distribution, thermogravimetric method (TG-DTG), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The results revealed that material loss during slow pyrolysis not only altered the chemical structure of the samples, but also induced the volume shrinking phenomenon, resulting in production of a rougher, porous structure with decreased crystallinity. Also, five times less total organic carbon (TOC) release was demonstrated by biochar compared to native material. Comparison of experimental results for BG sorption by PS and PS-B showed that sorption capacity increased after pyrolysis and that sorption kinetic was significantly improved. The BG sorption by both sorbents followed the pseudo-second-order reaction kinetic model, with the intraparticle diffusion model within pores controlling the adsorption rate in PS-B. Isotherm equilibrium modelling revealed that the Sips isotherm provided the best model fit with maximum sorption capacity of 82.53 and 101.11 mg/g for PS and PS-B, respectively. A possible sorption mechanism of BG was achieved through pore filling (porous diffusion), hydrogen bonding, electrostatic attraction and π-π interactions. The results demonstrated that biochar derived from peach stones can be used as a promising green material for removing BG from contaminated waters.

AB  - Renewable hydrogen produced from the waste streams can be a good option for clean energy production and reduction of greenhouse gases emissions into the environment. In this study, the potential for hydrogen production from the food industry wastewaters in Serbia and the further use of the calculated potentials were investigated. This was performed through two technological routes including the biogas steam reforming process and the electrolysis after biogas cogeneration process. Furthermore, the environmental impacts of these processes were considered. The total hydrogen potential via the biogas steam reforming process was 4094.70 tons, while the total hydrogen potential via the electrolysis after biogas cogeneration process was 1751.08 tons. These potentials can be used for direct energy production in the food industry, electricity production for the national electric grid, transport, injection in the natural gas grid and/or as a resource in the chemical industry. Regarding the Greenhouse Gas emissions reduction, hydrogen production by both routes represents a promising pathway. The results of this work can serve the decision makers to plan hydrogen application in the energy sector of the Republic of Serbia defining supporting measures for its application. Also, the presented analysis is enforceable in the Western Balkan countries for the application of hydrogen as an energy source in their systems for energy production, transport and economy.

AB  - The radical polymerization of monoethyl itaconate (MEI) was investigated in bulk and in solution at 60°C using a,a'-azobisisobutyronitrile as initiator. It was established that the obtained polymer poly(monoethyl itaconate) was insoluble in its monomer, implying that the bulk polymerization of MEI was a precipitation polymerization. The polymerization kinetics of MEI were discussed and compared to the polymerization kinetics of structurally similar alkyl itaconates. The homogeneous radical polymerization of MEI in tetrahydrofuran was not possible in the whole range of monomer/solvent concentration ratios, while the polymerization of MEI in methanol was homogeneous. The chain transfer constants to THF and methanol at 60°C were determined.
