One of the natural fiber sourced products is the rice plant. After the rice plant grown in the Thrace region is collected from the field, the remaining stalks can remain in the field for months without rotting and decomposition until the next planting process. Plant stems are tried to be removed by burning. In this study, in order to bring vegetable wastes to the economy and the environment, fiber was obtained from the paddy stalks by applying enzymatic pre-treatment and nonwoven fabric was formed by combing process. Then, biocomposite material was produced by using polylactic acid polymer by hot pressing process. The properties of the obtained composite materials were investigated by various characterization methods. Thanks to the enzymatic pre-treatment, foreign matter removal and hydrophilicity increase in the rice fiber were tried to be achieved. According to the tensile test results; It has been determined that the strength value of the nonwoven reinforced bio composite material decreases up to 10%. The glass transition temperature of PLA decreased as the fiber content increased and the loss modulus effect was felt. Dynamic mechanical analysis results show that at around 110 °C, cold crystallization of PLA occurs and high modulus values between the presence of fibers and cold crystallization and melting point
