“…There are agricultural biomass waste resources available in Poland [14,15]. A new phenomenon, which has been highly significant for the development of this sector, is the use of innovative, small-scale technologies of energy generation from renewable sources, which created the foundations for the growth of a citizens' energy sector, based on the initiative of the citizens and their communities.…”

The aim of this study was to investigate the influence of biomass micronization on energy production using a converted aircraft turbine AI-20. The test system was constructed in such a way to ensure continuous operation for a given period of time and was equipped in a chopper, a flail mill, and a micronizer. The turbine had the ability to produce energy from solid biomass and as well conventional fuels. The most energy was obtained from absolutely dry sunflower husk (17.27 MJ/kg) and the least from Poplar (7.82 MJ/kg). Miscanthus, wheat straw, and hay (approximately 17 MJ/kg) showed high values of energy production. In addition, the thermal decomposition of wheat straw at 350 and 450 °C was studied using the Py-GC/MS technique in a helium atmosphere to determine the gaseous compounds formed during biomass gasification under anaerobic conditions. The results obtained indicate the formation of compounds classified as phenols (vanillin, hydroxymethylfurfural).

“…Pinecone-activated carbon with ZnCl2 Methylene Blue [52] Forestry residues are also used for energy purposes, both in a treated and untreated form, for refined fuels [53,54], and after thermal pre-treatment. The utilisation of forest biomass residues for bioenergy production is a valuable alternative to fossil fuel combustion [3].…”

This paper presents the results of the analysis of the chemical composition and content of heavy metal contamination in forest logging residues, in order to assess the possibility for their further utilisation. The samples were divided into 9 groups, which included coniferous tree cones, wood, and other multi-species logging residues. The elementary composition, ash content, and calorific value were determined as energy use indicators for the samples. Additionally, the content of heavy and alkali metals, which may affect combustion processes and pollutant emissions, was tested. The high content of heavy metals may also disqualify these residues for other uses. The research shows that the test residues are suitable for energy use due to their high calorific value and low content of heavy metals. However, an increased ash content in some samples and the presence of alkali metals, causing high-temperature corrosion of boilers, may disqualify them as a potential fuel in the combustion process. The forest residues may be used in other thermal processes such as pyrolysis or gasification. A low content of heavy metals and a high content of organic matter permit the use of these residues for the production of adsorbents or composite materials.

The nonhomogeneous physical properties of the raw material in the form of shredded logging residues, and its composition may cause a serious problem in its further use. As a result of conducted research, it was found that the elemental composition of logging residues (low nitrogen and ash contents) is suitable for raw materials dedicated to energy use. The possibility of using this raw material for the production of briquettes and the correlation between the physical properties of the final product and the parameters of the raw material and the briquetting process were also determined. The material used for tests was wood chips with moisture contents of 10%, 15%, 20%, compacted in a closed chamber at the temperatures of 22, 73 and 103 °C at unit pressures of approx. 65 MPa. The best results were obtained for the material moisture content of 10%. It was found that the temperature of the wood chips during agglomeration influences the degree of compaction and durability of the obtained briquettes. It is more advantageous to conduct compaction at a higher temperature. The research also determined the effect of the fractional composition of the briquetted mixture divided into size groups 0–1, 1–4, 4–8, and 8–16 mm, its moisture and temperature of the process on the durability of the product. On the basis of the obtained results, the most favorable fractional composition of the briquetted mixture, its moisture and temperature of the compaction process were determined.
