In the present paper, different types of pure and commercial plastic waste from different EU countries (UK, France, Italy, and Romania) were investigated for microstructure surface morphology and chemical properties by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS). The goal of the current investigation was to determine the chemical composition of selected packaging materials and compare these measurements with data obtained through a carbon-hydrogen-nitrogen-sulfur-oxygen (CHNS-O) elemental analyzer, which is conventionally used to characterize waste materials. The capabilities of the experimental approach are discussed in connection with their application to the study of waste sample materials and in comparison with alternative experimental methods such as elemental analysis. The CHNS-O comparison is made between the present data obtained with SEM-EDXS instrument and EA 3000 elemental analyzer used in previews studies conducted by the authors. Results show a difference of composition among packaging from different countries that can affect the treatment adopted for its valorization and the strategies of circular economy.
