In order to identify the structure and morphology of the resulting surfaces from the abrasive water jet cutting, specialized analyses are performed. The biopolymers subjected to cold processing are Arboblend V2 Nature and Arbofill Fichte. According to the recorded data from the SEM (Scanning Electron Microscopy) and EDX (Energy-dispersive X-ray spectroscopy) analyses, uniformity as well as structural and morphological homogeneity of the samples is highlighted, together with the effect of the abrasive material, Garnet, on the structure and chemical composition of the cut surfaces. The abrasive outcome is found in the form of small streaks that has little influence on the roughness of the cut surfaces. Considering the obtained results, these biopolymers can be processed by cutting with an abrasive water jet in the conditions of obtaining a corresponding surface quality.
