This study develops a qualitative model for the energy requirements of the wood chipping process, establishing a relationship between energy needs and the variable properties of biomass. It emphasizes the connection between comminution machinery and the energy necessary for processing. While focused on chipping, the model can be adapted for various biomass types (e.g., agricultural residues) and different comminution machinery (e.g., hammermills) by adjusting material properties to fit machinery mechanics. The properties used in the model are designed to be easily measurable. Additionally, the model serves as a foundation for a quantitative approach that, through real machinery measurements and known wood properties, aims to address two key questions: 1) Would changes in the desired output size enhance total system efficiency, considering combustion process efficiency (e.g., unburned fuel)? 2) How can the energy used in comminution be optimized within the biofuel supply chain? Insights from this study could uncover new energy-saving opportunities and improve energy efficiency in the bioenergy sector. Moreover, the findings may guide optimized machinery choices for the biofuel supply chain and other applications. The study uniquely integrates mechanics, material sciences, and natural sciences to provide a comprehensive perspective.
