Introduction/Main Objectives: This study examines the influence of mechanistic parameters on manual biomass processing within the framework of green engineering and low-energy systems. The research focuses on the relationship between gear size in manually operated mechanical systems and the efficiency of biomass crushing, aiming to reduce reliance on electrification and fossil fuels in support of SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action).
Background Problems: The key problem addressed is how gear size affects the performance of manual biomass crushing systems. The research question is: Does increasing gear radius improve crushing efficiency in manual biomass processing systems?
Research Methods: An experimental design was implemented using three gear sizes (10 mm, 20 mm, and 30 mm) and four classes of wooden sticks with diameters ranging from 5 mm to 20 mm. Each gear-stick combination was tested three times to ensure reliability. Linear regression and statistical analysis were applied to determine the relationship between gear radius and crushing rate.
Finding/Results: The results indicate a strong positive correlation between gear size and crushing efficiency, expressed by the equation y=3.75x−12.5y = 3.75x - 12.5y=3.75x−12.5. The 30 mm gear achieved 100% crushing efficiency, while the 10 mm gear achieved only 25%. Larger gear radius significantly increases torque and biomass conversion efficiency.
Conclusion: Manual mechanical systems demonstrate substantial potential as zero-carbon-energy technologies for biomass waste conversion. This study contributes to mechanical engineering by clarifying the impact of gear size on ultra-low-energy systems, reinforcing the need for affordable, human-powered, and sustainable green technologies.
