In this paper, an optimization model for biogas power plant feedstock mixture with respect to feedstock and transportation costs using a differential evolution algorithm (DEA) is presented. A mathematical model and an optimization problem are presented. The proposed model introduces an optimal mixture of different feedstock combinations in a biogas power plant and informs about the maximal transportation distance for each feedstock before being unprofitable. In the case study, the proposed model is applied to five most commonly used feedstock in biogas power plants in Croatia and Hungary. The research is performed for a situation when the biogas power plant is not owned by the farm owner but by a third party. An optimization procedure is performed for each scenario with a cost of methane production that does not exceed 0.75 EUR/m3 in 1 MWe biogas power plant. The results show the needed yearly amounts and the maximum transportation distance of each feedstock.

“…The heat generated is used for the biogas plant own needs, which account for about 8% of total production, while the electricity is switched on to the grid. [Wiater 2017, Szatyłowicz et al 2016 The ash from the biomass combustion was taken from the municipal heat and power plant. Generation of electricity is carried out using steam boilers, two coal-fired and two biomass ones.…”

The aim of the study was to evaluate the available waste in view of the heavy metals and fractions thereof. Three waste materials were analyzed in the work, namely dried, granular sludge, digestate from agricultural biogas plant and ash after combustion of biomass from the combined heat and power plant, in terms of the content of heavy metals in them. Their mobility through fractional analysis was determined and the possibilities of their agricultural use were assessed. The analyzed waste was varied due to the pH. Biomass ashes had the highest pH and it was alkaline. The pH of the dried precipitate was neutral and digestate was slightly alkaline. In the analyzed wastes, the content of permissible concentrations of heavy metals determined in the Regulation of the Minister of the Environment was not exceeded. The content of individual elements varied and depends on the type of waste tested. The conducted sequential analysis showed that various metal fractions are present in the tested wastes. The content of heavy metals in individual factions was varied and the content of mobile and potentially mobile fractions, i.e. metals of fractions I and II, was lower compared to the non-mobile fractions III and IV.

“…On the basis of the growing interest in renewable energy sources and the support of the Polish government for development of innovative technologies in the field of energy production, the development of the hydrogen production and distribution market is also expected. Energy-rich and green gas fuel produced from organic waste can contribute to the diversification of energy sources and increase the energy security of the country [Kazimierowicz 2014, Wiater andHorysz 2017].…”

The increasing demand for electrical energy and environmental concerns associated with conventional means of its generation drive the interest in alternative fuels. Biohydrogen, widely considered as fuel of the future, is one of such alternatives. To date, research results suggest that biological routes are the most promising for hydrogen production, especially dark (hydrogen) fermentation. Hydrogen fermentation can be performed with agricultural and food processing wastes as substrates. In this paper the most important factors influencing dark fermentation are reviewed and analyzed. These are: pH, partial pressure, temperature, and retention time. The biohydrogen generation efficiency is also presented with respect to different substrates. It should be also pointed out that many factors are still unknown; thus, the process requires conducting further research.
