Abstract: In light of sustainability and circular economy, the use of biochar as a filler in composites has considerable potential and needs further investigation. Several studies have documented the use of industrial and agricultural waste to enhance the characteristics of gypsum–based composites. However, few studies have investigated the incorporation of biochar and fragrance in gypsum plaster. Gypsum plaster is an excellent building material with a wide range of applications, and it is an environmentally friendly material. Many studies have shown that adding biochar to composites greatly enhances their properties, demonstrating that biochar is an excellent additive. An in–depth study of the addition of fragrance and biochar to gypsum plaster, as well as its potential for future uses, was provided in this research. A study of potential knowledge gaps was also undertaken, and improvements were proposed. Three sample mixtures have been made, the first sample being the control sample (mixture without biochar), the second and the third mixtures are made by adding different percentages of biochar. Biochar made from wood chips prepared by pyrolysis at 500 °C was added to the plaster at 2 % and 5 % by weight of gypsum. Results show that adding biochar to gypsum plaster does not significantly affect the setting time, nor improve the fire properties of the plaster. It also has no significant effect on the wettability of the plaster. In terms of adhesive strength, it was discovered that including 5 % biochar into fragrant gypsum plaster enhances the plaster's adhesion strength when compared to incorporating 2 % biochar.
