“…Tobacco (Nicotiana tabacum) is one of the most widely cultivated non-edible crops worldwide and has been used to produce cigarettes for a long time [1]. It is well known that the huge economic value of tobacco means it occupies an important position in the field of global agriculture [2]. As the largest producer and consumer in the world, China manufactures a large amount of tobacco, with approximately 1 million tons of related waste produced every year [3].…”

With the increasing concerns of human health and the ecological environment, tobacco stalks from the cigarette industry have been recognized as hazardous wastes requiring cautious treatment. However, there is still a lack of a simple and efficient route for full utilization of tobacco stalks. Herein, we attempted to convert tobacco stalk waste to value-added carbohydrates, bio-oil, and biochar through sequential hydrothermal and pyrolysis treatments. The results showed a high carbohydrate yield under the optimized condition using a microwave reaction system. The subsequent pyrolysis of residual solids at high temperatures could produce unexpected high-level aromatic chemicals including phenols and even benzenes—difficult to form without the facilitation of catalysts or salts. The obtained by-product biochar showed rapid absorption of tetracycline in 5 min and gradual introparticle diffusion from 30 to 240 min. The isotherm result had the characteristics of the Langmuir model, displaying homogeneous active sites on the biochar surface. Probably due to the hydrothermal pretreatment before pyrolysis, the obtained biochar exhibited a high adsorption capacity toward tetracycline without introducing the activation chemicals. These results illustrate that the proposed strategy may pave the way for dealing with tobacco wastes in the agricultural field.

“…The culture of tobacco, Nicotiana tabacum L., is of great relevance to Brazil, one of the main worldwide producers and exporters. Its seeds are used to produce new seedlings for extraction of the leaves, which is the crop's profitable product (Hirsch & Landau, 2020, Boettcher et al, 2020.…”

The biopolymer coating use on seeds has aroused the interest of the agricultural sector due to its low cost, reduction of impacts on the environment and improvements in productivity and yield of major crops, being chitosan an important polymer for application in seeds. Considering this knowledge, the present study aimed to evaluate the application effect of a bioproduct based on chitosan, from the parameters of physiological quality, vigor, and biochemistry in tobacco seeds. Seeds of the Virginia variety were submitted to treatments: 0.0 (witness); 0.5; 1; 2.5; 5; and 10% were used to obtain first count values, germination test, seedling length and fresh mass, and chlorophyll and carotenoid contents. The bioproduct had a positive effect on chlorophyll a, b, and carotenoids at 10% FTSeed concentration and seedling length under 5.25% FTSeed. The study pointed out that the bioproduct has a favorable action on the development and leaf pigments, being an alternative biostimulant with less impact on the environment for the agricultural sector.
