“…Cellulose, a homopolysaccharide (carbohydrate), occurs as an abundant component in the plant cell wall and comprises repeated units of β- d -glucopyranose. 70 It can be obtained from the leaves, bark, and fruits of several plant species, and is biocompatible and biodegradable. 71 In addition, with minimal treatment procedures, it can be used as a biomaterial for various tissue engineering and wound healing applications.…”

“…Commercially, cellulose is extracted from wood, agricultural residues, grasses and other plant substances [106]. Commercial use of cellulose has a long history dating back to the nineteenth century, with cellulose derivatives still widely used for a wide range of applications because of their ability to form films in addition to their spinnability [107], coupled with its physical properties [108][109][110][111][112]. Applications include spun fibres, food products, cosmetics, building materials, pharmaceuticals and medical applications.…”

Plastics have transformed our modern world. With a range of outstanding properties, they are used in an ever-widening range of applications. However, the linear economy of their use means that a large volume of plastics is discarded after use. It is believed that approximately 80% of the estimated total 6.3 Bt of plastics ever produced have been discarded, representing not only a huge loss of valuable resources, but mismanaged waste is also the origin of an ever-increasing environmental disaster. Strategies to prevent loss of materials resources and damage to the environment are elements of a circular plastics economy that aims to maintain plastics at their highest value for the longest time possible and at the same time improve the economy and prevent detrimental environmental impact. The latter in particular is driving recent changes in policies and legislation across the world that are rapidly being introduced in order to solve these environmental issues. The achievement of a circular economy will require not only innovative technical developments, but also major economic investment and changes to business practice coupled with significant changes in social behaviour. This paper summarizes the complex and highly interrelated technical issues and provides an overview of the major challenges, potential solutions and opportunities required to achieve and operate a circular plastics economy. This article is part of a discussion meeting issue ‘Science to enable the circular economy’.

“…During synthesis, cellulose forms microfibrils (2–30 nm diameter) with both crystalline and amorphous regions. Microfibrils will aggregate into bigger fibrils (30–100 nm diameter, 100–500 μm length) and then into fibers (100–400 nm diameter, 0.5–4.0 mm length) [ 97 ]. Several studies have proven the effectiveness of IL as a solvent for cellulose [ 98 , 99 , 100 , 101 ] and cellulose composites [ 48 , 49 , 102 ], making it one of the most promising materials for the fabrication of fiber materials using IL as a solvent.…”

Natural biomacromolecules such as structural proteins and polysaccharides are composed of the basic building blocks of life: amino acids and carbohydrates. Understanding their molecular structure, self-assembly and interaction in solvents such as ionic liquids (ILs) is critical for unleashing a flora of new materials, revolutionizing the way we fabricate multi-structural and multi-functional systems with tunable physicochemical properties. Ionic liquids are superior to organic solvents because they do not produce unwanted by-products and are considered green substitutes because of their reusability. In addition, they will significantly improve the miscibility of biopolymers with other materials while maintaining the mechanical properties of the biopolymer in the final product. Understanding and controlling the physicochemical properties of biopolymers in ionic liquids matrices will be crucial for progress leading to the ability to fabricate robust multi-level structural 1D fiber materials. It will also help to predict the relationship between fiber conformation and protein secondary structures or carbohydrate crystallinity, thus creating potential applications for cell growth signaling, ionic conductivity, liquid diffusion and thermal conductivity, and several applications in biomedicine and environmental science. This will also enable the regeneration of biopolymer composite fiber materials with useful functionalities and customizable options critical for additive manufacturing. The specific capabilities of these fiber materials have been shown to vary based on their fabrication methods including electrospinning and post-treatments. This review serves to provide basic knowledge of these commonly utilized protein and polysaccharide biopolymers and their fiber fabrication methods from various ionic liquids, as well as the effect of post-treatments on these fiber materials and their applications in biomedical and pharmaceutical research, wound healing, environmental filters and sustainable and green chemistry research.
