Conventional energy sources often do not fully satisfy the needs of a modern economy, especially given the climate changes associated with them. These issues should be addressed by diversification of energy generation, including the development of renewable energy sources (RES). Solid biomass will play a major part in the process in Poland. The function of rural areas, along with a well-developed agricultural and forest economy sector, will be a key aspect in this as these areas are suitable for solid biomass acquisition in various ways. This study aimed to determine the solid biomass energy potential in the commune of Goworowo to illustrate the potential in the smallest administrative units of Poland. This research determined the environmental and natural conditions in the commune, which helped to identify the crucial usable solid biomass resources. The total energy potential of solid biomass resources in the commune of Goworowo amounted to 97,672 GJ y−1. The highest potential was accumulated in straw surplus (37,288 GJ y−1) and the lowest was in wood from roadside maintenance (113 GJ y−1). This study showed that rural areas could soon play a significant role in obtaining solid biomass, and individual communes could become spaces for the diversification of energy feedstock.

Extracts from the June collection of aerial parts of Helianthus salicifolius A. Dietr and Helianthus tuberosus L. were obtained using carbon dioxide supercritical fluid extraction with water as co-solvent. The antimicrobial effect in vitro of these extracts was then determined against reference species of bacteria, as well as against fungi (represented by Candida spp.). Both extracts were found to possess antimicrobial activity, with MIC = 0.62–5 mg mL−1 for bacteria and MIC = 5–10 mg mL−1 for yeasts, and both extracts demonstrated suitable bactericidal and fungicidal effect. The highest activity was observed against S. aureus ATCC 29213 (MIC = 0.62 mg mL−1 for H. salicifolius extract; MIC = 2.5 mg mL−1 for H. tuberosus extract) as confirmed by time–kill assay. Higher antioxidant activity was found for H. tuberosus extract (EC50 = 0.332 mg mL−1) as compared to that of H. salicifolius (EC50 = 0.609 mg mL−1). The total polyphenol content (TPC) expressed as gallic acid equivalents (GAE) was 13.75 ± 0.50 mg GAE g−1 of H. salicifolius extract and 33.06 ± 0.80 mg GAE g−1 of H. tuberosus extract. There was a relationship between the antioxidant potential of both extracts and TPC, but not between antistaphylococcal activity and TPC. The ATIR–FTIR spectra of both extracts showed similar main vibrations of the functional groups typical for phytoconstituents possessing bioactivity. The obtained data suggest potential application of these extracts as natural antioxidants and preparations with biocidal activity. Additionally, both extracts may be regarded as potential natural conservants in cosmetics, as well as natural preservatives in food.

The extracts from the aerial parts of Helianthus salicifolius A. Dietr and Helianthus tuberosus L. collected in June were obtained using carbon dioxide supercritical fluid extraction with water as co-solvent. The antimicrobial activity in vitro of these extracts were determined against the reference species of Gram-positive and Gram-negative bacteria as well as fungi, representing by the yeast species of Candida spp. The following parameters were estimated: minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) or minimum fungicidal concentration (MFC). Both extracts were found to possess antimicrobial activity with MIC = 0.62-5 mg mL-1 for bacteria and MIC = 5-10 mg mL-1 for yeasts, showing bactericidal (MBC/MIC = 2-4) or fungicidal effect (MFC/MIC = 1-2 ). The highest activity was observed against S. aureus ATCC 29213 (MIC = 0.62 mg mL-1 for H. salicifolius extract; MIC = 2.5 mg mL-1 for H. tuberosus extract). Bactericidal effect of both extracts against S. aureus ATCC 29213 was confirmed by time-kill assay. Higher antioxidant activity was found for H. tuberosus extract (EC50 = 0.332 mg mL-1) as compared to that of H. salicifolius (EC50 = 0.609 mg mL-1). The total polyphenol content (TPC) expressed as gallic acid equivalents (GAE) was 13.75 ± 0.50 mg GAE (g of H. salicifolius extract)-1 and 33.06 ± 0.80 mg GAE (g of H. tuberosus extract)-1. There was a correlation between the antioxidant potential of both extracts and TPC but not between antistaphylococcal activity and TPC. The obtained data suggest potential application of these extracts as the natural preparations with the biocidal activity, including those with antistaphylococcal activity. Besides, both extracts may be regarded as potential natural conservants in cosmetics as well as natural preservatives in food.

Biomass remains one of the most important materials for the production of renewable energy in the European Union. Willow can be one of the sources of biomass, and its production can also be profitable on soils with low quality. A proper selection of raw material for energy production should be based not only on the cost effectiveness or crop yield, but also on the environmental impact and the cost it incurs. The aim of this work was to evaluate the external environmental costs of the production of willow chips of seven willow genotypes, produced for energy generation on marginal cropping lands. The environmental external costs of chips production were estimated against the amount of emissions calculated according to the LCA method (ReCiPe Midpoint) and its monetary value. The external environmental cost of willow chips production amounted to €212 ha−1 year−1, which constituted 23% of the total production cost of willow chips. The external cost of production of 1 Mg d.m. of willow chips for the best yielding variety averaged €21.5, which corresponded to 27% of the total production cost. The research demonstrated that a proper selection of an optimal variety may lead to the reduction of the external cost.

Due to the geographical and economic conditions, northern European and, particularly, the Baltic Sea region (BSR) countries are especially predisposed to biomass production and bioenergy generation. Assuming the large diversity in biomass potential and bioenergy technologies among the countries, the purpose of this study was to assess the potential of biomass and characterise the development of bioenergy technologies in nine BSR countries (Denmark, Germany, Estonia, Finland, Latvia, Lithuania, Poland, Sweden and Norway). However, Russia was not included in our analyses since data complementary to the other BSR countries could not be obtained. The largest technical potential of agricultural biomass, manure and slurry was found to be in Germany and Poland. Sweden has the largest number of pellet production plants, but the highest production was found in Germany, which is the leading biogas producer among the analysed countries (92% of all biogas plants). The gross production of derived bioheat was the highest in Sweden. Germany had the highest final energy consumption of bioheat in all sectors. The current study found that bioenergy constitutes an important share in the renewable energy structure across the majority of the BSR countries and confirmed the large diversity in biomass potential and bioenergy technologies resulting from geographical location, land use structure, population size and other factors beyond this analysis. The northern European example is a good path to follow by other regions of the world and can help improve their bioenergy development efforts.

Willow biomass is used as a bioenergy source in various conversion technologies. It is noteworthy that apart from the beneficial environmental impact of a willow plantation, the biomass quality is also very important as it has an impact on the effectiveness of its use and emissions produced in various bioenergy technologies. Therefore, this study analysed the thermophysical properties and elemental composition of 15 genotypes of willow biomass from two plantations situated in the north of Poland, harvested in two consecutive three-year rotations. The differences in the moisture content, ash content and the lower heating value were mainly determined by the genotype, i.e., by genetic factors. In contrast, the content of carbon, nitrogen, sulphur and hydrogen was determined by the location (environmental factors), but also by the genotype, and by a combination of these factors. The following were the mean levels of the willow biomass characteristics, regardless of the location, genotype and harvest rotation: 48.9% moisture content, 1.26% d.m. ash content, 19.4% d.m. fixed carbon, 79.4% d.m. volatile matter, 19.53 MJ kg−1 d.m. higher heating value, 8.20 MJ kg−1 lower heating value, 52.90% d.m. carbon, 6.23% d.m. hydrogen, 0.032% d.m. sulphur, 0.42% d.m. nitrogen. The present research has shown that the selection of the willow genotype is important for the quality of biomass as energy feedstock. However, plantation location, as well as successive harvest rotations, can have a significant impact on the biomass elemental composition.

Currently, 57.4% of the European Union (EU-28) population live in houses which usually need separate boilers to generate thermal energy. The research presented in this paper pertained to a detached house in the north-east of Poland, in which thermal energy was generated over 12 consecutive years by burning wood briquettes. This study analysed the quality and quantity of wood briquettes, energy consumption and cost of thermal energy generation for the house with the use of an automatic biomass burning unit, compared with other types of fuels. The annual consumption of briquette energy was 124.5 GJ year−1. The average annual cost of thermal energy generation for a house was 739 € year−1. When the cost of the boiler purchase and its service and fuel purchase costs were taken into account, the 12-year operating cost for a briquette-fired boiler was found to be similar to the operation cost for a coal-fired boiler and higher by 21% compared to willow chips-fired boiler. The operation of a boiler fired with other fuels, like pellets, natural gas or heating oil during the same period was more expensive by 39%, 46% and 157%, respectively.

In the bio-based economy concept, any biomass should not be used directly for energy purposes without considering the possibility of using it for bioproducts with higher added value. Extractable phytochemicals found in lignocellulosic biomass of perennial industrial crops (PIC) are used in the pharmaceutical, cosmetics, chemical, food and feed industries. Therefore, these compounds should be obtained first, and only the so-called PIC extraction biomass should be used, for example, for the production of bioenergy. An efficient low-energy and environmentally friendly method of extracting phytochemicals from the plant biomass is supercritical carbon dioxide (scCO2) extraction. The aim of the study was to assess the thermophysical properties and chemical composition of 19 types of PIC biomass previously subjected to two types of scCO2 extraction compared to the biomass before extraction. The biomass after pure scCO2 and scCO2/H2O (1 wt%) extraction contained less ash (by 4.9 and 11.3%), carbon (by 3.1 and 7.8%), hydrogen (by 5.8 and 8.9%), nitrogen (by 4.5 and 6.8%), sulfur (by 3.8 and 3.8%), lignin (by 5.4 and 1.1%), hemicellulose (by 14.4%) and more chlorine (by 4.7 and 15.3%) compared to the biomass before extraction. In addition, the biomass after extraction with pure scCO2 contained more cellulose and was characterized by lower moisture content and higher heating value and lower heating value. However, the biomass after scCO2/H2O extraction contained more substances soluble in cold and hot water. Generally, the bark of four short-rotation coppice (SRC) species was characterized by a high content of nitrogen, sulfur, substances soluble in cold and hot water, other soluble substances and at the same time low cellulose content (26–28% d.m.). In turn, the wood of all SRC species was characterized by a high cellulose content (51–56% d.m.). However, all herbaceous crops and grasses contained more chlorine, hemicellulose and generally less lignin compared to the SRC biomass. To assess the practical suitability of the PIC biomass extraction for the production of bioenergy (solid, liquid or gaseous biofuels), further research is needed.

In sustainable production, information about product costs should be complete. Not only economic but also environmental aspects need to be taken into consideration. The aim of this study was to estimate environmental external costs of poplar short rotation woody crops (SRWC) cultivation according to different soil enrichment procedures for wood chips production. The base scenario was to grow unfertilized crops. Three other scenarios were analyzed: mineral fertilization, lignin application, and combined lignin and mineral fertilization. The assessment of the environmental costs was based on emissions originating from production of poplar wood chips. The costs were calculated based on the emissions and their monetary value. The environmental external cost of the production of poplar chips was €137.24 ha−1 year−1 on average, and corresponded to 27.5% of the internal cost. The external cost of poplar chips production relative to a mass unit was €15.67 Mg−1 d.m. on average, corresponding to 20% of the total production cost. Our analysis shows that field emission and harvest generate most of the external cost. The highest cost was associated with particulate matter formation and terrestrial acidification.

Plantations of perennial industrial crops (PIC) could be important sources of lignocellulosic biomass. These crops can be classified into three groups: short rotation coppice (SRC) – wood, herbaceous crops (semi–wood) and grasses (straw). Comparing various PIC genotypes directly under similar environmental conditions over many successive harvest rotations is necessary to accurately determine the yielding potential and energy efficiency of lignocellulose biomass production. Therefore, the aim of this study was to determine the energy input, energy yield value and the energy efficiency indices of biomass production for 26 PIC genotypes (fifteen SRC, six herbaceous crops and five grasses) harvested in six successive annual rotations. The significantly highest energy yield value throughout the experiment (2012–2017) was obtained from the Ekotur willow variety (1857 GJ ha–1). Among the 26 PIC, the top ten for energy yield value and energy gain in the six successive rotations included five SRC willow (Salix spp.) genotypes: (Ekotur, Start, Żubr, Turbo, UWM 095), three grass genotypes: Miscanthus sacchariflorus ((Maxim.) Hack.), M. sinensis ((Thunb.) Andersson), Spartina pectinata Bosc ex Link and two herbaceous crops: Sida hermaphrodita Rusby L., Helianthus salicifolius A. Dietr. The significantly highest energy ratio (22.3) was obtained for the production of M. sacchariflorus. The next three places were occupied by willows, Ekotur, Żubr and Start and the index for them was 8–10% lower than for M. sacchariflorus. This research should be continued for the entire lifetime of a plantation, which is set up for at least 15 years even though some SRC may be exploited for more than 20 years. Therefore, it is important to assess individual PIC genotypes in later years of their cultivation in terms of their productivity and energy efficiency indices.

Sugar beet is a key resource in a future chemical platform of a sugar biorefinery. Decontrol of production amounts of sugar in the European Union in 2017 necessitates the search for other profitable production alternatives in the sugar industry. One possible approach is based on the direct processing of beetroot to bioethanol. This paper discusses research which has described and compared process flows (PFD) as well as incomes and financial expenditures (CAPEX and OPEX) of two technological variants that involve the direct processing of sugar beet to ethanol: one with the use of Betaprocess® technology, and the other serving as a reference technology. The Betaprocess® technology is an original pretreatment method whereby plant cells are degraded efficiently, owing to which the feedstock is fed directly to digesters, where it is fermented effectively. The research results show that the whole processing cycle is improved by inclusion of Betaprocess®, with such gains as lower investment and operational costs of the installation in comparison to the reference technology. This paper also contains an analysis of the direct processing of sugar beet to ethanol in view of the binding law, including the legal regulations on liquid biofuels and biocomponents.
