AB  - The decrease of fossil fuel resources as well as associated pollution induced by its applications has
increased the interest in findings of renewable fuels from various biomasses such as wood, energy
crops, and various waste disposed from agricultural and food-industry activities. Especially
interesting is lignocellulosic waste (LCW) biomass, found in large quantities after processing of the
raw biomass, which pose certain energetic properties that might be used to fulfil future
sustainability demands. This paper describes the thermal decomposition of waste peach stones (PS)
investigated via thermogravimetric (TG) analyses. TG/DTG analyses provided a set of experimental
mass loss data (obtained under different conditions), which were modelled by different kinetic
models, resulting in parameters that might be used for industrial application of the tested biofuel.
The goal of analyzing the kinetics of thermal degradation was to establish a relationship between
the rate of degradation, degree of conversion (α) and temperature. In this sense, the investigation of
the kinetics of thermal degradation was performed in non-isothermal conditions, with the heating
speed varying from 5 to 20 ºC/min in an oxygen stream. Activation energy (Ea) of the PS thermal
degradation was determined using Flynn-Wall-Ozawa (FWO) isoconversional model free method.
The possible reaction mechanism that controls the process was investigated by the method of Coats-
Redfern (C-R). The values of the Ea obtained by this method were not constant with the change in
the degree of conversion (α), indicating that the thermal decomposition of PS represents a complex
process that cannot be described by a one-step reaction in the entire range of conversions. PS
waste samples investigated in this paper, have certain physical and chemical properties which
satisfy request for energy density, small ash content and safe burn out. Presented results might
support the value of biowaste in a future circular bio economy of Serbia.

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.
