The aim of this study was the production of compressed charcoal from the pyrolysis of Virginia tobacco stalks. This compressed charcoal has physicochemical properties close to or superior to charcoal from wood. After obtaining charcoal dust from tobacco stalks due to the pyrolysis process, filler and additives were added to increase the burning rate and particle binder. The mixture was then pressed and dried. In this project, wheat starch, corn and tapioca with 5 %, 10 % and 15 % contribution were used to synthesize charcoal dust particles. After completing the compressed charcoal production process, the physicochemical properties of the compressed charcoal were compared with the compressed charcoal available on the market. The results of variance analysis showed that the effect of treatment on moisture content, volatile matter content, ash content, fixed carbon, calorific value, number of hits, ignition duration and burning time factors was significant at the 1 % probability level. Also, the results showed that the calorific value of the compressed charcoal, which is an important property to consider in the study, is almost twice as much as that of the compressed charcoal available on the market.
