Conventional energy sources are increasingly at odds with contemporary environmental
sustainability objectives; hence, there is a growing interest in renewable and environmentally
friendly alternatives. Biodiesel is characterized by low toxicity, high biodegradability, and little
emissions; yet, it is susceptible to oxidative breakdown because of its polyunsaturated fatty acid
content. This circumstance reduces the fuel's storage lifespan and adversely impacts engine
performance. A natural phenolic compound called Tobacco extract was used in this study to
make biodiesel-diesel (50% biodiesel + 50% diesel) blends more resistant to oxidation. The
extract from the soxhlet process was mixed into the fuel at a concentration of 3000 ppm, and
its effects were compared to those of TBHQ, a man-made antioxidant. We tested the antioxidant
activity using FT-IR (Fourier Transform Infrared Spectroscopy), TGA (Thermogravimetric
Analysis), and DSC (Differential Scanning Calorimetry), which are thermal and chemical
methods for characterizing things. We tested the extract's ability to remove free radicals using
DPPH and ABTS methods. The results show that Tobacco is a strong natural antioxidant that
greatly slows down the oxidative breakdown of the biodiesel-diesel mix. Tobacco possesses
significant promise as a natural addition in biofuel technology.
