“…This study evaluated juvenile scalloped hammerhead sharks' ingestion of plastic debris in the southeastern Gulf of California. Previous studies have reported a high presence of plastic debris in coastal sediments in this area [8,27]. Hence, the presence of plastics in the gastrointestinal tract of sharks is expected.…”

According to the International Union for Conservation of Nature Red List, the scalloped hammerhead (Sphyrna lewini) is a critically endangered species, primarily due to intense fishing and other anthropogenic effects such as pollution. Nowadays, plastic debris contamination is a subject of concern due to its extensive presence in the sea and the digestive tracts of many fish species. The possible effects of plastic debris as a vector of other pollutants are still unknown. We analyzed the digestive tract of hammerhead sharks to investigate the correlation between plastic and other anthropic debris contamination and feeding habits in the eastern region of the Gulf of California. A total of 58 specimens were analyzed from the coastal area, revealing a plastic occurrence frequency of 79.3%. Of these, 91.4% corresponded to fibers, and 8.6% to fragments. The composition of the polymers was primarily cellulose (64.4%). According to their diet, these organisms exhibit benthopelagic habits, feeding both in the water column and on the seabed. These results indicate a high level of contamination of anthropogenic cellulosic microfibers in the area. This changed according to the year, indicating that the anthropic debris ingestion is related to the discharges of human activities and their seasonality rather than to a selection process by the sharks. Although cellulosic microfibers are recognized as a biomaterial, they can harm marine species, posing an additional threat to this iconic shark.

“…In the 1940s the massive production of plastics increased exponentially (Adjani Diankristanti et al, 2024;Liwarska-Bizukojc, 2021), reaching a global amount of 400.3 million tons (Mt) in 2022 (Plastics Europe, 2022). Among them, the use of petroleum-derived plastics has become a problem worldwide, due to the well-known impact on human health and the environment (González-Rojo and Díez-Antolínez, 2023;Pinho et al, 2022;Simó-Cabrera et al, 2021). In fact, these materials are widely distributed around the world, contaminating diverse 10.3389/fmats.2024.1405483 ecosystems, also including the deepest marine ecosystems (de Mello et al, 2024) and one of the most critical problems are their long persistence in these environments (Amabile et al, 2024;Binelli et al, 2022;Pinho et al, 2022).…”

The scientific community has focused on finding sustainable alternatives, including bioplastics, whose properties are similar to conventional plastic and whose production comes from renewable sources or biological matter (Atiwesh et al, 2021;Ciftcioglu-Gozuacik et al, 2023).…”

Global concern about plastic pollution is forcing new policies and modifications of human consumption as well as promoting new research lines aiming at the replacement of non-degradable plastics with other polymers more environmentally friendly. Addressing food waste and promoting circular economy strategies, among other approaches, are crucial in reducing environmental impacts and fostering sustainability in several sectors like the agri-food industry. The European Union’s Circular Economy Action Plan is a significant initiative in this direction. Biotechnological processes, especially the valorisation of agri-food waste to produce highly marketed biomolecules like poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) using microorganisms as cellular factories, offer promising avenues for achieving these goals. PHBV is a biodegradable polymer firstly characterised as an isolated biopolymer from bacterial biomass. This biopolymer shows interesting physicochemical properties making possible immense potential in various applications due to its biocompatibility and sustainability, thus revealing it as a good candidate to replace plastics produced by chemical synthesis from petroleum (which are highly recalcitrant and consequently pollutants). This review critically analyses the PHBV synthesis and end-of-life scenarios from their synthesis using chemical and biological pathways, through the forms of biotechnological operation and production, to the forms described until the moment of recycling.
