Biogas production from lignocellulosic biomass, such as wheat and rapeseed straw, is an essential strategy for sustainable energy generation. However, the efficiency of anaerobic digestion depends on physical characteristics substrate, particularly particle size, which influences microbial accessibility biogas yield. This study aims to optimize straw size enhanced methane by evaluating different fractionation levels. The was processed using a hammer mill separated into three fractions (2.4 mm, 1 mm) alongside non-separated finely ground (2 samples. chemical composition analyzed X-ray fluorescence (XRF), key parameters pH, dry matter (DM), organic (ODM) were assessed. results indicated that had lower pH (6.05) DM than (7.01). yield analysis demonstrated varied with size. For samples achieved highest (132.87 m3 Mg⁻1), whereas decreased increased fragmentation, observed material (206.65 Mg⁻1). carbon-to-nitrogen (C/N) ratio in (153.82), potentially limiting activity, while finer more balanced ratios. These findings highlight importance mechanical pretreatment optimizing provide insights improving straw-based systems.
