“…However, it is important to note that most plant oils require modifications at their naturally occurring reactive sites, such as ester groups and carbon-carbon double bonds, before they can be utilized in biopolymer production (Ike et al, 2021; Ruiz-Rico and Barat, 2021). Therefore, these reactive sites, including the carbon-carbon double bonds found in fatty acid chains, play a crucial role during polymerization (Biermann et al, 2021;Rajput et al, 2023). In simpler terms, these double bonds act as excellent starting points for biopolymer production.…”

As climate change intensifies and the need to reduce human-caused emissions becomes more urgent, transitioning to a bio-based economy is essential. This paper explores the diverse industrial applications of plant oils as sustainable alternatives to petroleum-based products, including their use in food, polymers, lubricants, surfactants, pesticides, emollients, and biofuels. This review delves into biosynthetic pathways, detailing the key enzymes and processes involved in the synthesis of triacylglycerol. It thoroughly discusses how genetic and metabolic engineering can not only increase oil yields but also modify fatty acid compositions to better meet industrial requirements. By understanding genetics and utilizing advanced biotechnologies, the oil content and quality of plant sources can be significantly enhanced, aligning with both sustainability goals and industrial demands. This paper provides a comprehensive overview of the current uses and genetic engineering of plant oil production, proposing innovative strategies such as utilizing oils from biomass or cultivating non-edible oil crops. These approaches aim to establish a sustainable industrial system, reduce reliance on fossil fuels, and promote the growth of an environmentally responsible bio-based economy. Additionally, the review highlights future directions, examining the economic implications and environmental benefits of adopting plant oils across various sectors and positioning them as pivotal to achieving an eco-friendly, bio-based economy.

“…These epoxides can react both with CO 2 and with diamines to produce vegetable oil‐derived polycyclic carbonates and polyamines, precursors for NIPU synthesis. The reaction of materials having multiple cyclic carbonate functions with those containing amine groups leads to bio‐based PUs with diverse properties 8 . Vegetable oils with a high content of unsaturated fatty acids produce polymeric precursors with higher functionalities, which can be related to the crosslinking density of the NIPU as well as to the thermal and mechanical performance 9 …”

In this work, non‐isocyanate polyurethane (NIPU) films are synthesized from sunflower oil (SFO) with the object of using a renewable resource and establishing a nonpolluting process. SFO also has the advantage of having a higher level of unsaturation than other commercial oils, which provides more reactive sites to be chemically modified. This feature enables a higher degree of conversion to the two monomers, cyclocarbonate, and polyamine‐polyol. NIPU is obtained from their mixture and further crosslinking at 90°C allows the films with suitable mechanical properties to be used in biomedical applications. However, NIPU does not show antibacterial activity, so the surface must be modified. Two methods are used: layer‐by‐layer coating of alginate‐chitosan, and immersion in tea tree oil (TTO), previously activating the surface with acrylic acid (AANIPU). Surface modifications are confirmed by increased hydrophilicity, thermochemical changes, and a drop in mechanical performance. TTO on NIPU films inhibits bacterial growth against S. aureus and E. Coli. NIPU and AANIPU can be accepted as noncytotoxic, while incorporation of the two agents can produce cytotoxicity. No previous reports of such modifications have been found on NIPU films, which appear as promising alternatives for biomedical applications.
