This study focused on the evaluation of briquettes made of rose oil processing wastes obtained from during the production of rose oil with lignite coal dust (LCD). In the experiment, a hydraulic press with the maximum compression pressure of 350 MPa was used for production of briquettes. Four mixtures prepared (rose oil processing wastes-lignite coal dust (%), dry weight basis) were 100-0; 75-25; 50-50, and 25-75. The mixtures were briquetted at room temperature without using a binder for 30 seconds under pressure of 35 MPa. All briquettes were stored under ambient conditions for 7 days before testing. At the end of the experiment, full cylindrical briquettes with the height of 100 mm and the diameter of 60 mm and hollow-core briquettes with the height of 100 mm and the diameter of 80 mm with 20 mm central hole were produced. Physical tests of briquettes such as shattering resistance, abrasive resistance, air humidity resistance, water intake resistance, and density measurement were performed. Results showed that the density values of briquettes varied between 1239 and 1274 kg/m(3). Shattering resistance value of all briquettes changed between 95.46 and 98.72%. The results of abrasiveness test showed that the increase in the amount of lignite coal dust in the composition of briquettes led to decrease in abrasive resistance value. Briquettes showed no structural changes in terms of water intake resistance and were determined to be pretty solid based on humidity resistance test. Furthermore, flue gas emissions values measured after combustion was found to be below the limit values specified in Turkish Regulation on Air Pollution Caused by Heating.
