Green composites of polylactic acid (PLA) with microcrystalline cellulose (MCC) as reinforcement of the polymer matrix were produced by melt blending to improve the brittleness of PLA. The MCC was prepared by hydrolysis of wheat straw cellulose with sulfuric acid to remove amorphous area. The biocomposites were prepared with different MCC contents (2, 4, 6, 8 wt%). Scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, differential scanning calorimetry, Fourier transform infrared and mechanical testing were used to study the structure and properties of MCC and biocomposites. The tensile modulus and the strength of PLA/MCC biocomposites increased from 206 to 262 MPa and from 67.35 to 73.01 MPa, respectively.
