The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene at room temperature for 24 h (Sep–ZrI) or 95 °C 4 (sample Sep–ZrII). efficiency of the obtained removal phosphate from aqueous solutions initial pH = and 8 was investigated. Characterization samples shows that synthesis a higher shorter time provides slightly content amorphous Zr phase, which is deposited on fibers as thin layer agglomerated nanoparticles. Compared to Sep, have...

This paper investigates the influence of air flow rate in a three-phase air-lift reactor on sorption toxic dye, Brilliant green, onto promising and efficient sorbent, sour cherry stone biochar. In order to gain comprehensive insight into sorbent/sorption behaviour, biochar was characterized by Fourier transform infrared spectroscopy with attenuated total reflection, pH suspension, point zero charge, scanning electron microscopy energy-dispersive X-ray diffraction. The experiments were...

Global discussion on climate change and strengthening environmental protection has been launched, especially in the last three decades. As is a result of greenhouse gas emissions, different mechanisms were introduced order to reduce this impact, surely most significant was set by Kyoto Protocol. The Republic Serbia considers proper policy as one its priorities. switch from traditional renewable energy sources carries valuable improvements economic efficacy, Government encourages use for...

Biogas represents a promising source for the production of clean energy. The objective this paper was to quantify potential reduction emissions environment during electricity from biogas in comparison with environmental effects same amount fossil resources (coal Kolubara basin and natural gas). Basis impacts work annual plants total capacity 80 MW. This study has shown that power MW results in: substitution up 840 kt coal 123.2 million m3 gas; greenhouse gases range 491.16 - 604.97 CO2-eq,...

The aim of this paper was to present the energy flows in life cycle biogas utilization systems (cogeneration and transportation), as well their mutual relations, starting from providing feedstock for digestion through end-of-life management system fertilizer on agricultural land. This study carried out analysis two scenarios (biogas cogeneration transportation) using performance Mirotin plant (1 MW) Serbia. Results obtained have shown that analyzed scenario positive balances (52,114 53,585...

The aim of this paper is to determine the current situation in field geographical indications schemes (GI), obstacles for futures development and provide recommendations GIs Serbia, Bosnia Herzegovina Montenegro. quality confirmation consumers that foodstuff a traditional product produced certain area with attributes. Although Western Balkan countries are reach well-known products have excellent ago-ecological conditions production, not developed. In applied comparative methodology,...

The aim of this study is to analyze the possibility achieving goal related share biogas energy in final consumption Republic Serbia up 2030 which refers reach 2% electricity produced from biogas, 1% transport and heat accordance with recommendations European Biomass Association (AEBIOM). analysis was performed on basis estimated potential, where crops dedicated production, animal husbandry, municipal solid waste, waste meat industry dairy wastewater as well Serbian development strategy until 2030.

Manure is a by-product at agricultural farms that can consist of excrement, bedding, food, and other substances. significant form organic fertilizer, but it negatively impacts the environment. The objectives this study are to determine quantities manure classify them depending on size type in Serbia quantify greenhouse gas emissions from management. About 8.6 million m3 fresh liquid about 20.4 tons solid generated Serbia. dominant types manures pig cattle manures. Approximately 81% total...

Metal ions can be eliminated from aqueous solutions using biosorbent, a substance made plant biomass. This study investigated the potential use of Arundo donax stems as cheap, natural biosorbent to remove cobalt (Co2+) an solution. The was characterized by chemical composition analysis (cellulose, hemicellulose, and lignin), point zero charge (pHPZC), scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction analysis, Fourier-transform infrared spectroscopy. According...

The increased presence of phosphorus in natural waters causes eutrophication, which is a growing problem for water supply, especially the case and artificial lakes (reservoirs). Eutrophication can be slowed down by reducing input this element, primarily treatment waste before their discharge into recipients. Adsorption one most effective economical methods removing from water, but only if adsorbents with high adsorption capacity low cost are used. In work, composite were synthesized using...

The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene, at room temperature for 24 h (Sep –ZrI) or 95 °C 4h (sample Sep –ZrII). efficiency of the obtained adsorbents removal phosphate from aqueous solutions initial pH = 4 and 8, was investigated. Characterization samples showed that higher synthesis shorter time provided slightly content amorphous Zr-phase, which deposited on fibers as a thin layer agglomerated nanoparticles. Compared...

Biogas is a promising source for energy production in future systems. In this paper, the flows life cycle of real biogas plant (Mirotin-Vrbas) thermal were considered, starting from corn silage production, cow manure transport, process anaerobic digestion and to use solid liquid digestate crops. Four indicators used evaluate work. The obtained results showed that system has positive balance 62.418 GJ an efficiency 6,1, which indicates terms substitution fossil fuel consumption, heat good alternative.

The need to reduce the use of fossil fuels, due harmful impact on environment and growing energy demand, have led production from renewable sources.Access clean has become imperative for social progress.Improving existing biomass resources into efficient carriers such as biogas anaerobic digestion potential provide reliable energy, with environmental protection, rationally using natural generation new jobs.Along reducing greenhouse gas emissions, improves security and, a source, enables...
