“…The process of transforming the advanced biofuels and biogas into bioenergy with low emissions of greenhouse gas should be regarded in a cost effective manner, paying attention to the need for development of the corresponding high-tech bioenergy infrastructure [9][10][11][12][13][14]. To streamline the process, the European legislators thought of conceiving thresholds to keep a balance between the need to produce clean energy and biodiversity demands.…”

The Solow-Swan macroeconomic model reveals the fact that the marginal capital rate of the bioenergy sector, as well as the bioenergy productivity and productivity of the resources variation, having positive values of their estimated coefficients, have the capacity of stimulating the sustainable economic development of an emerging country, such as Romania. The economic model substantiated by the correlations between the macroeconomic indicators evaluates the convergence in relation with the European Union (EU) average. The main objective of this paper is to analyze the impact of bioenergy on sustainable economic development. The econometric analysis revealed the fact that the bioenergy productivity, the productivity of the resources and the capital productivity of the bioenergy sector have a positive and statistically significant impact on the sustainable economic development. Data was collected from The European Statistical Office and analyzed with SPSS 22 statistical software package. Quantitative methods highlight the disparities between developed and developing countries of EU in terms of bioenergy use and efficiency.

“…The factors obtained for M. × piperita L. var. citrata Ehrh.-'Bergamot' (highest emission factors) are comparable with emission factors for oak tree leaves [49] or eucalyptus globulus [2]. However, the examined biomass is not the one with the lowest emission potential.…”

“…The market of low-power (from several kW to 2 MW) heating plants fueled with biomass offers many innovative technical solutions. Replacing coal with biomass fuel is beneficial in that it contributes to reducing gas emissions [1]; is an excellent solution for the socio-economic development of disadvantaged areas, rural or peripheral [2]; and has the possibility of being implemented at a large scale [3]. In terms of energy yield, 2 tonnes of biomass is on average an equivalent to 1 tonne of hard coal.…”

The paper presents the results of research on the physicochemical properties of plant biomass consisting of four mint species, these being Mentha × piperita L. var. citrata Ehrh.-'Bergamot', Mentha × rotundifolia L., Mentha spicata L., and Mentha crispa L. The research conducted consisted of the technical analysis of biofuels-determining the heat of combustion and the calorific value of the material under study, and the content of ash, volatile compounds, and humidity. In addition, elemental analysis was carried out for the biomass under study by determining the content of carbon, hydrogen, nitrogen, and sulfur. The research demonstrated that Mentha × piperita L. var. citrata Ehrh.-'Bergamot' had the highest energy potential with a gross calorific value of 16.96 MJ·kg −1 , and a net calorific value of 15.60 MJ·kg −1 . Among the tested materials, Mentha × rotundifolia L. had the lowest content of ash at 7.23%, nitrogen at 0.23%, and sulfur at 0.03%, and at the same time had the highest content of volatile fraction at 70.36%. When compared to hard coal, the estimated emission factors indicated a CO reduction of 29-32%, CO 2 reduction of 28-31%, NO x reduction of 40-80%, SO 2 reduction of 92-98%, and dust reduction of 45-61%, depending on the type of biomass used.Energies 2020, 13, 55 2 of 13 of harmful gas and dust emissions (CO 2 , NO, SO 2 ) [10], and reduction of mineral extraction and thus curbing environmental degradation caused by uncontrolled decomposition of unused biomass [11,12].One of the basic goals of a low-emissions economy is to reduce the flow of biodegradable waste mass within certain time limits. Reaching this objective will not be possible without the implementation and development of installations for the thermal conversion of residues from agricultural and agriculture-related production, especially in systems for managing residues in the herbal product industry [13]. Installations for the conversion of residues from the sector of agricultural, horticultural, and herbal production should ensure the possibility of fulfilling the adopted obligations to reduce biodegradable waste, and secondly, they should provide significant amounts of electricity and heat, mainly treated as energy from renewable sources [14,15]. In addition, it is still important to search for new, alternative energy sources characterized by low emission levels, including, apart from greenhouse gases, low dust emission [16,17]. Due to the growth of the herbal production sector, one can observe high potential for energy generation in the residues from herb production and, more importantly, in residues that cannot be offered on the consumer market.Poland is considered as a country with great capabilities in both the production of high-quality herbal raw materials and herbal processing. This is due to the fact that over the last decade the number of farms growing herbs in Poland has increased from 18,000 to 30,000, and plantations of herbs now cover an area of over 30,000 ha, whereas in the countries of the entire European Union, th...

“…The dust emission index, related to the ash content of the individual raw materials, is the highest for WRON (5.31 kg•Mg −1 ) and the lowest (14% lower) for WSBL (4.57 kg•Mg −1 ). The analysis of the emission factors showed that the analyzed biomass is characterized by higher emission rates relative to mint [46], tree leaves [47], rice straw [48], similar to eucalyptus globulus wood [49] and larch needles [34] and lower relative to jackfruit peel and jackfruit seeds [32]. Nevertheless, in relation to hard coal [33], it is characterized by low emissions in terms of the analyzed factors, which indicates that this fuel as environmentally friendly.…”

Using Wood-Based Waste from Grapevine Cultivation for Energy Purposes

This paper presents the possibility of the energetic utilization of biowaste in the form of lignified one-year shoots from the cultivation of grapevines of the Seyval Blanc (WSBL), Solaris (WSOL), Regent (WREG) and Rondo (WRON) varieties, grown in temperate climate zones. A technical analysis, an elemental analysis and the determination of the highest heat value and lowest heat value were performed to define the quality parameters of waste as fuel. In addition, the emission factors of SO2, NOx, CO, CO2 and dust were estimated to demonstrate the impact of potential biowaste from combustion. Based on the stoichiometric equations, the exhaust gas composition, the theoretical oxygen demand and the total flue gas volume were evaluated. The study showed that the material with the highest energy potential was WREG (LHV-16.19 MJ·kg−1), with an ash content of 3.68%, while the lowest potential was found for WRON (LHV-15.88 MJ·kg−1), with an ash content of 4.21%. The study showed that the use of the studied viticulture waste instead of hard coal could reduce CO emissions by 26–27%, CO2 by 24–26%, NOx by 55–56%, SO2 by 96–97% and dust by 77–80%.
