“…Chewing gum waste also represents a social problem because it substantially decreases the utility and aesthetic value of public places (Simonek, 2011), generating untidiness and discomfort, as well as promoting adverse social behavior in the population. Among the tentative strategies to reduce the amount of chewing gum waste thrown onto the streets, some chewing gum waste collection campaigns have been proposed, as well as the use of improved cleaning methods (Liu and Jiang, 2003), the incorporation of anti-sticking agents into chewing gum formulations (Sozzi and Del Visco, 2011;Bullus, 2017), the production of bio-chewing Gum (Ribadeau- Dumas and Mentink, 2004;Palabiyik et al, 2018;Saberi et al, 2018), the making of wraps for their hygienic disposal (Simonek, 2011), and their use as a filling in the formulation of plastic blends useful for manufacturing chewing gum waste collection containers (Bullus, 2017). The latter implies having to throw the chewed gum into special containers, rather than into ordinary trash bins without any appeal for the consumer.…”

Once chewed, chewing gum becomes a disposable and non-degradable cumulative residue that causes environmental, economic, and social problems. Collecting and treating chewing gum waste until its properties are adapted for some profitable use will generate environmental and economic savings. In this work, chewing gum waste was collected, sanitized, and subjected to a laboratory-scale rubber vulcanization-like process with sulfur. The evolution of the process was monitored via sequential measurements of torque and the acquisition of a series of ATR-FTIR spectra on the raw and resulting material of aliquots isolated from the reaction medium every 10 minutes for 4 hours. The absorbance values of the signals in the series of ATR-FTIR spectra were normalized and subjected to a descriptive statistical analysis, which allowed detecting intensity variations in bands attributed to carboxylate, as well as a slight decrease in the intensity of the bands attributed to hydroxyl, carbonyl, methylene in alpha to carbonyl, and other CHn groups in aliphatic fragments. These intensity changes and the trend of rheometric measurements during the process (vulcanization curve) evidenced that chewing gum waste did indeed react. Its vulcanization process had an absolute cross-linking maximum 5,15 minutes into the process and caused a remarkable increase in the torque of the resulting material; the Shore A hardness changed from 20 to 95 units, and the density varied from 1 280 to 1 510 kg/m3. These findings hint at an alternative treatment to reduce environmental pollution and revalue chewing gum waste.

A comprehensive literature search was conducted in PubMed, Cochrane Library, Web of Science, Scopus, the National Library of Medicine (NLM) catalog, and Google Scholar from January 1980 up until October 2023 on plants in the Gundelia genus. Gundelia L. (Asteraceae) has been treated as a monospecific genus with G. tournefortii L. (1753: 814) in most recent floras with wide variation in corolla color, but nowadays, the genus consists of 17 species. The unripe inflorescences of these species, especially Gundelia tournefortii L., are consumed in many ways. 'Akkoub' or 'akko' in Arabic, “Kangar” in Persian, and “Silifa” in Greek are the common names of G. tournefortii L., also known as tumble thistle in English. They have been used in traditional medicine to treat bronchitis, kidney stones, diarrhea, stomach pain, inflammation, liver and blood diseases, bacterial and fungal infections, and mumps. Based on recent studies, their extracts have exhibited hepatoprotective, hypolipidemic, antioxidant, anti‐inflammatory, and antimicrobial effects. Moreover, a variety of phytochemicals, including terpenoids, sterols, and fatty acids, as well as vitamins and minerals, have been identified in this genus. This study reviewed the ethnobotany, phytochemicals, and biological activities of the plants in the Gundelia genus as functional foods and herbal remedies.
