In the quest for sustainable energy solutions, a comprehensive review by Segun E. Ibitoye and a team of international researchers provides valuable insights into the realm of biomass solid fuels (BSFs). Published in the Journal of Bioresources and Bioproducts, the study offers a detailed examination of the various sources of biomass, the methods by which they are processed into solid fuels, and the critical morphological and microstructural properties that determine their physical, mechanical, and chemical characteristics.
The review underscores the importance of biomass as a renewable energy source, with wood constituting 67% of the biomass used for bioenergy generation. It highlights the role of different biomass sources, including wood residues, agro-residues, and municipal solid wastes, each with its unique advantages and challenges. The researchers also discuss various processing methods, such as gasification, torrefaction, carbonization, hydrothermal carbonization (HTC), and pyrolysis, each with its own set of advantages and disadvantages in terms of energy performance, techno-economics, and climate impact.
A key finding of the review is the significant impact of processing methods on the durability and strength of BSFs. Thermal treatment, for instance, often leads to less durability due to voids and gaps between particles, while HTC alters surface morphology, creating cavities and pores. The review also points out that the addition of binding materials can significantly improve the properties of BSFs, potentially optimizing them for industrial-scale commercial use.
The study concludes that while BSFs show promise as a sustainable and renewable energy source, further research is needed to fully understand the complex interplay between biomass sources, processing methods, and the resulting fuel properties. This comprehensive review is a valuable resource for energy professionals, researchers, and policymakers interested in harnessing the potential of biomass solid fuels for a more sustainable future.
