Tobacco processing industries generate a large volume of tobacco waste as a by-product during the production of tobacco products. These wastes are typically discarded through methods like incineration or burial. However, this discarded material still contains significant economic value that is often overlooked. One of the most valuable components of tobacco waste is its high nicotine content. Nicotine is a key raw material for a variety of products, including those in the pharmaceutical and personal care industries, particularly to produce hygienic products such as nicotine patches or e-cigarette liquids. Therefore, finding ways to extract and utilize the nicotine from tobacco waste could have both economic and environmental benefits. The extraction of nicotine from tobacco waste is an important issue, as it presents an opportunity to create a valuable resource for various industries, while also mitigating the environmental harm caused by the burning of tobacco waste. Incineration and burial contribute to air and soil pollution, which can have long-lasting negative impacts on the environment. By extracting nicotine from these wastes, industries can repurpose what would otherwise be discarded material, reducing waste and contributing to more sustainable practices. This experiment focuses on a simplified approach to nicotine extraction from tobacco waste using an alkaline extraction method. In this process, sodium hydroxide (NaOH) solution is used to break down the plant material and release nicotine. Following this, diethyl ether is employed for solvent separation to isolate the nicotine from the extract. To confirm the presence of nicotine, picric acid and methanol are added to the solution, inducing the formation of a picrate precipitate. The appearance of a colorless precipitate after cooling the mixture serves as a positive indicator of the presence of nicotine in the extract. This approach provides a relatively straightforward and effective method for extracting nicotine from tobacco waste, offering a potential pathway for repurposing this by-product into valuable resources while reducing environmental impact.
