Seaweed-Based Polymers from Sustainable Aquaculture to “Greener” Plastic Products

Seaweed-based films for sustainable food packaging: properties, incorporation of essential oils, applications, and future directions

“…Alginate has been studied by Rinaudo [24] as a potential solution for food packaging and more recently, in addition to alginate, Carina and Sharma [2] use polysaccharides as food packaging material isolated from different seaweed to further the current research on seaweed. The overall polymer condition of seaweed and its characteristics to form various plastic kinds are described by Zhang and Show [25], Pacheco and Cotas [26]. Seaweed polymers are extracted and reviewed by Shravya and Vybhava Lakshmi [27], Lim and Yusoff [28] for application in bioplastic manufacturing.…”

Novel seaweed-based bioplastic: A prospective Life Cycle Assessment

“…In the compounding and homogenization step, the alginate extracted in the biorefinery step is mixed with cellulose and glycerol, which are used as functional additives within the formulation. Glycerol is a widely used plasticizer with hydrophilic biopolymers [23], improving the mechanical properties of alginate-based plastic, such as water permeability and thermal resistance [53]. Cellulose is used as a reinforcing filler.…”

“…Rimundo [20] is among the first to investigate the use of alginate as possible material for food packaging and, more recently, Carina et al [21] expand the state of the art on seaweed polysaccharides as food packaging material using not only alginate but also other polysaccharides extracted from brown, red and green seaweed. Pacheco et al,Zhang et al and Zanchetta et al [17,22,23] describe the general status of seaweed polymers and their properties to produce different plastic types. Shravya et al and Lim et al [24,25] review the processes to extract seaweed polymers for use in bioplastic production.…”
