“…It should be noted that all of the studied varieties have a lower calorific value than Cabernet, Merlot, Prosecco or Verduzzo [13], and WREG has a similar value to Chardonnay [43] (Table 4). When comparing HHV results with values for other biomass types, similar values were noted for cereal straws (wheat, barley, rye), cereal grains [14], or olive, fig and almond trees [45]. On the other hand, when comparing the ash content, the grapevine varieties studied demonstrated ash contents that were below the average indicated by Fernández-Puratich et al [43], but similar to the ash contents obtained for peach, plum, hazelnut or olive [45].…”

“…Grapevines, unlike other orchard species, require intensive pruning to obtain adequate production volume and quality [13]. The recovery of plant biomass in the form of grapevine pruning residues and wastes and the possibility of their use for energy purposes represents one of the most important innovations in the agricultural sector [14][15][16][17][18][19]. Agricultural residues can become a potential source of biomass for energy production because they are available annually [20,21].…”

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%.

“…The Indian Ministry of Power has announced a policy for co-firing 5-10% of biomass pellets in all of the country's thermal coal power plants. According to estimates, co-firing in a thermal plant with a 1000 megawatt (MW) capacity would require about 0.3 million tonnes of biomass pellets [5]. To secure a wide and consistent supply of raw materials for the production of pellets, it is necessary to investigate the effect of process parameters such as moisture content and particle size on the characteristics of pellets.…”

Fuel pellets are a popular form of biomass energy due to their high energy density, ease of handling, and reduced emissions. The quality of fuel pellets is influenced by various factors, including the moisture content and particle size of the raw materials (Soybean straw and cotton stalk) used during the pelletization process. In this study, the effect of moisture content and particle size on the characteristics of fuel pellets produced using a flat die type pelleting machine was investigated. Different moisture content levels (ranging from 20 to 30%) and particle sizes (ranging from 4 to 8 mm) were used to pelletize a biomass feedstock. The pellet characteristics, including pellet durability, bulk density and water resistance and energy consumption were evaluated. The results showed that both moisture content and particle size significantly influenced the characteristics of the fuel pellets as well as energy consumption. Based on the findings, an optimal moisture content of 25% and particle size of 6 mm were determined for producing fuel pellets with desirable characteristics and low energy consumption was required using the flat die type pelleting machine. These results can provide valuable insights for biomass pellet producers and researchers in optimizing the pelletization process to achieve high-quality fuel pellets with improved properties.
