Possibilities for utilization of tobacco stems for production of energetic briquettes
Tobacco (Nicotiana tabacum L.) belongs to the group of plants that produce agricultural raw material. Besides leaves, which are used to satisfy the passion for smoking, tobacco can be used for producing oil and biodiesel, because it contains 30-40% of vegetable oil. Because of its content of citr...
