Environmental problems caused by plastics are getting serious every year, and among them, environmental problems caused by microplastics are getting particularly serious. Microplastics are largely divided into primary microplastics, which are made small to be added to fabric softeners, cosmetics, and toothpaste, and secondary microplastics, which are destroyed by the natural environment and become smaller in size. These microplastics are not filtered in wastewater treatment plants due to their small particle size, but are discharged and accumulated in the sea as they are, and can directly affect human health. Accordingly, many studies have been conducted to replace plastic microbeads using eco-friendly biomaterials. This study was a basic study to replace primary microplastics using cellulose beads, and it was intended to develop a technology to control the particle size when preparing beads using the spraying method with a coaxial needle. Cellulose was dissolved by mixing TEAOH and Urea, and beads were formed using a spraying method with a coaxial needle and solidified in acetic acid solution. The effects on spraying conditions on the particle size of cellulose beads will be discussed.
