摘要：This paper presents the results of new composite materials based on polylactide and coffee grounds sorption characteristics study. New material, that include coffee grounds as additive material is cheaper than one of common polylactide. All types of dishes cam be made from new material and they also will be biodegradable, as made from polylactide. The sorption properties and characteristics were tested in different liquid medium. The last was chosen among the most wide spread mediums which are contact with dishes during its operational life. It was found, that optimal content of coffee grounds is 40 wt.% as for level of impact strength also for complex of sorption characteristics.
