Special Issue Information

Dear Colleagues,

The 3rd Bioenergy International Conference is organized by researchers of the Polytechnique Institute of Portalegre (Portalegre, Portugal) and the University of Jaén (Jaén, Spain), and its goal is to bring together academics, researchers and companies in an international forum to discuss matters related to bioenergy technologies, economic and policy aspects.

Papers published in the Special Issue “Advances in Bioenergy from Biomass and Waste” (Selected Papers from the 3rd Bioenergy International Conference) will be focused on recent advances in biomass and waste management, biomass conversion processes, biomass applications and bio-products’ end-use. Nevertheless, we also welcome regular research or review articles on all aspects of bioenergy technology.

The demand for clean energy to improve waste valorization and enhance resource utilization efficiency has been increasingly recognized in the last few years. In this context, the co-carbonization of different waste streams, aiming at solid fuel production, appears as a potential strategy to address the challenges of the energy transition and divert waste from landfills. In this work, refuse-derived fuel (RDF) samples were subjected to the co-carbonization process with low-quality animal fat waste in different proportions to assess the synergistic effect of the mixture on producing chars with enhanced fuel properties. Dry (DC) and hydrothermal carbonization (HTC) tests were conducted at 425 °C and 300 °C, respectively, with a residence time of 30 min. The RDF sample and produced chars with different animal fat incorporation were analyzed for their physical, chemical, and fuel properties. The results demonstrated that increasing the fat proportion in the samples leads to an increase in mass yield and apparent density of the produced chars. Furthermore, char samples with higher fat addition presented a proportional increase in high heating value (HHV). The highest values for the HHV corresponded to the char samples produced with 30% fat incorporation for both carbonization techniques (27.9 MJ/kg and 32.9 MJ/kg for dry and hydrothermal carbonization, respectively). Fat addition also reduced ash content, improved hydrophobicity in hydrochars, and lowered ignition temperature, although additional washing was necessary to reduce chlorine to acceptable levels. Furthermore, fat incorporation reduced concentrations of elements linked to slagging and fouling. Overall, the results demonstrate that incorporating 30% fat into RDF during DC or HTC is the most effective condition for producing chars with improved physical, chemical, and fuel properties, enhancing their potential as alternative solid fuels.
