Special Issue Information

Dear Colleagues,

The growing global demand for sustainable and low-carbon energy sources has placed biomass combustion at the forefront of renewable energy research.

This Special Issue, "Recent Advances in Biomass Combustion", aims to highlight recent advances in the utilization of biomass for heat and power generation.

It seeks to compile contributions that advance both the scientific understanding and technological readiness of biomass combustion as a key contributor to global decarbonization and the circular economy.

Topics of interest include, but are not limited to, the following:

  • The characterization of various biomass fuels;
  • Combustion mechanisms;
  • Biomass thermal conversion;
  • Process optimization;
  • Experimental studies;
  • Numerical modeling (e.g., CFD);
  • Life-cycle assessments that evaluate the environmental and energetic efficiency of biomass combustion systems.

We seek contributions discussing innovations that enhance conversion efficiency, reduce emissions, and promote the integration of biomass technologies in distributed energy systems and hybrid configurations. We particularly welcome studies that address the techno-economic feasibility, fuel flexibility, and ash behavior of biomass in industrial-scale applications.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Urban tree-management operations generate substantial amounts of woody biomass that often remain underutilized despite their potential value as a local renewable fuel. This study investigates the possibility of using woodchips and sawdust delivered from municipal tree-cutting activities as boiler fuel, with a specific focus on how fuel moisture, particle size, and natural-fiber packaging influence combustion performance and emission characteristics. In collaboration with a municipal greenery-cutting company, representative batches of biomass were collected, characterized through proximate and ultimate analyses, and combusted in a small-scale boiler. Unlike conventional densification routes (pelletization/briquetting), the proposed approach uses combustible natural-fiber packaging to create modular ‘macro-pellets’ from minimally processed urban residues. The study quantifies how this low-energy packaging concept affects emissions and boiler efficiency relative to loose chips/sawdust at two moisture levels. The results demonstrate that packaging the fuel in jute bags markedly improved performance for both woodchips and sawdust by stabilizing the fuel bed, enhancing air distribution, and reducing emissions of incomplete combustion products. Boiler efficiency increased from approximately 60% for raw unpackaged fuels to 71–75% for the dried and jute-packaged variants. The findings highlight that simple preprocessing steps—drying and packaging in natural-fiber bags—can substantially enhance the energy recovery potential of urban green waste, offering a practical pathway for integrating municipal biomass residues into a sustainable fuel.
