The Agricultural and food industry generates large amounts of food waste. However, one of the biggest contributors to plastic pollution is food packaging materials. Most food packaging is designed to be single-use and is nonrecyclable, or they are not. There are developments toward creating more eco-friendly packaging but based on the Pew and SYSTEMIQ model, and plastic trash would decrease by 38% and cost an additional US$140 billion. One strategy that the model predicted could be useful is “reduction and substitution.” This strategy would yield a 52% decrease. Even though it would cost an additional US$250 billion, it seems as though food scientists are headed toward finding alternative methods to produce plastic. Scientists are looking into novel approaches to developing safer film materials that are also cost-effective. Some studies have looked into using components recovered from waste products and by-products as a suitable form of food packaging. Other studies have considered developing active packaging from seafood waste, such as biopolymers and bioactive agents (Debeaufort, 2021; Suleria et al., 2015).

Ulvan is the major sulfated polysaccharide isolated from green algae that accounts for 9–36% of alga mass (Kidgell et al. 2019). It is identified as an anionic, water-soluble and stable polysaccharide that contains glucose, xylose, rhamnose and glucuronic acid monomers (Madany et al. 2021). As reported by the previous studies, a common ulvan structure (Figure 7.2) composed of sulfated rhamnose is linked to glucuronic acid in ulvanobiuronic acid 3-sulfate or iduronic acid in ulvanobiuronic acid 3-sulfate (Ganesan et al. 2018: Madany et al. 2021). Apart from this common structure, two other structures of ulvan can be identified in several green algal species as branching glucuronic acid to O-2 rhamnose3-sulfate and O-2 partially sulfated xylose (Madany et al. 2021). Although ulvan has been subjected to research for developing films and coatings, no scientific evaluation has been reported on the applicability of ulvan structure in making packaging materials. However, ulvan is a potential source of active packaging as it contains a broad range of bioactive properties such as antioxidant, anticancer, antifungal, anticoagulant and antitumor activities (Kidgell et al. 2019).

Furthermore, the use of products obtained from plant sources with antimicrobial capacity has shown promise in the development of new drugs, as for the creation of active packaging capable of offering safer, better quality products with a longer shelf life. Besides, intelligent packaging can monitor the condition of the packaged food, providing information on its quality during transport and storage13,14.
