“…The lowest sulphur content was recorded for wheat straw and it is at a comparable level for literature data. It should be emphasised that the sulphur content in rapeseed pods is high, compared to other biomass kinds, as it is about 80% higher than in rapeseed straw, wheat straw or Miscanthus and about 60% higher in relation to apple, cherry, plum or peach wood [40], hence the use of rapeseed pods in the energy industry may contribute to increased SO 2 emissions in relation to the mentioned above biomass.…”

The paper presents the possibility of managing forest and agricultural biomass for energy purposes in the aspect of environmental protection and sustainable development. The results of experimental studies of physicochemical properties of four types of plant biomass, i.e., a wheat straw, oat grains, larch needles and rapeseed pods are shown. The study consisted of determining the energy parameters in the form of gross and net calorific values of the test material. In addition, the ash and moisture content of the material was tested. Moreover, an elementary analysis for the tested materials by determining the content of carbon, hydrogen and nitrogen was performed. The studies have shown energy potential for the examined materials, in particular oat grains, where the gross calorific value amounted to 17.16 MJ·kg −1 , net calorific value to 15.37 MJ·kg −1 and ash content to 2.71%. Larch needles are characterised by the highest carbon content of 45.73%, oat grains by hydrogen at 6.53%, 1.53% nitrogen and sulphur 0.11%. Determined emission rates indicate a reduction of 31-41% CO, 30-39% CO 2 , 22-55% NO x , 95-97% SO 2 , 47-97% dust depending on the type of used biomass in relation to hard coal.

“…Methane fermentation is considered an ideal way to manage organic waste and biomass from targeted energy crop plantations [GRALA et al 2014]. Agricultural residues can become a potential source of biomass for energy production because they are available annually [BURG et al 2017; VAN DAM et al 2007].…”

Biogas plants are one of the most stable sources of renewable energy. Currently, there is a noticeable increase in the amount of post-production residues from agricultural production and agri-food processing (fruit and vegetable processing, fermentation, beet pulp, or lignocellulosic waste), which, can be used for biogas production after appropriate pretreatment. The aim of this study was to examine the possibility of using the biomass produced during the cultivation of grapes on a selected farm as a substrate for a biogas plant, taking into account the production process. The research was carried out in 2018-2020 in a vineyard located in the Sandomierz Upland in the south-eastern part of Poland. Own rooted vines were grown as a single continuous string with a trunk height of 40 cm and a length of one fixed arm approx. 0.9 m, on which six pivots were left every year after applying a short cut, from which 12-16 fruit shoots were derived, the so-called grapevines. Leaves were collected at random from three locations on the fruiting shoot, a total of 30 leaves in each replicate. Each sample consisted of 1/3 of the leaves collected at the bottom, 1/3 in the middle, and 1/3 at the top of the canopy. Leaf area was estimated with a model 3100 area meter on a sample of 30 leaves from each replicate. Both the quantity and quality of the obtained material as a substrate for methane fermentation were evaluated. Biogas yield tests in optimal conditions for mesophilic bacteria were conducted on three substrate samples referred to as 'Regent', 'Seyval Blanc', and 'Solaris'. The yields of the tested material ranged from 51.0 to 59.0 Nm 3 biogas per Mg of biomass.

Background: The huge quantity of agricultural biomass has led Europe to issue directives to ensure that it is properly managed. Among the permanent European crops area, olive, orange, and apricot orchards are the most present. The management of these crops produces significant amounts of biomass, which very often is burned in the field. With a view to the circular economy, this study aims to analyze the secondary metabolites present in the biomass of these three crops.Results: Secondary metabolites were extracted from wood and bark by an Accelerated Solvent Extractor at 120 using water, ethanol, and a mixture of water and ethanol as solvents. In addition, the identification of the molecules present in the extracts was attempted using high-performance liquid chromatography (HPLC) coupled with a mass spectrometer (MS). The analysis showed that in the three crops, the highest yields of extract were measured in the bark while the species that has shown the highest yield compared to the others was the olive tree. HPLC-MS technique revealed interesting molecular compounds, such as catechins, epicatechins, and oleuropein, respectively in the apricot and olive extracts. Conclusion:The biomass extractives of these three species highlighted an interesting potential for applications in various industrial sectors such as for example, pharmaceutical, nutraceutical, and agriculture.
