In this study, it was aimed to re-incorporate spartium junceum flowers, which became garbage after essential oil extraction, into the raw material cycle through cellulose extraction and to ensure recycling. Cellulose extracted from waste flowers is a commercial product and used in the synthesis of cellulose acetate, which is the raw material of our further studies. Cellulose and holocellulose were extracted from waste flowers for the synthesis of cellulose acetate. Later, both were used to synthesize cellulose acetate. At the end of the study, cellulose acetate was obtained with a yield of 8.37% by cellulose extraction from waste flowers, while cellulose acetate was obtained with a yield of 8.14% in the holocellulose method. The characterization of the obtained cellulose acetate was done by FTIR XRD and DSC analysis. The study has shown that cellulose acetate can be synthesized from waste flowers. Synthesis made from cellulose was preferred because it is more environmentally friendly and purer cellulose acetate is obtained.
