Effect of glycerol plasticizer loading on the physical
This might be ascribed to plasticizers' role in upsetting and restructuring intermolecular polymer chain networks, converting all free volumes into the thicker film 63,64,65. Figure 4
Bioplastics for a circular economy | Nature Reviews Materials
Bioplastics — typically plastics manufactured from bio-based polymers — stand to contribute to more sustainable commercial plastic life cycles as part of a circular economy, in which virgin...
Poly(lactic acid) (PLA) and polyhydroxyalkanoates (PHAs
The bioplastics are considered compostable if within 180 days, a complete microbial assimilation of the fragmented food source takes place in a compost environment. The difference between the two branches of bioplastics is shown in Fig. 4. 24 An illustration of the bioplastics' life cycle is presented in Fig. 5. The cycle initiates by growing
A Comprehensive Review on the Emerging Roles
Plasticisers are non-volatile compounds of film-forming agents with low molecular weight, which is widely used in polymer industries [108]. Their crucial role is to improve the flexibility and...
Bio-based Additives
Bioplastics make up around one percent of the 360 million or so tonnes of plastic produced every year. That may sound small, but demand is rising fast, as is production capacity. In 2025 the global bioplastics production capacity was 2.11 million tonnes and that is forecast to rise to 2.43 million tonnes by just 2024.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Can bio-based plasticizers replace conventional plastic goods?
- The challenge to implement this new class of natural-based plasticizers matches the increasing interest of material researchers and industries in new bio-based materials, made from renewable resources with the potential, not to totally replace but to reduce the use of conventional plastic goods.
- Why are bioplastics not a viable alternative to low-cost plastics?
- This is due to their limited production, the precursors for the development of bioplastics, and their limited mechanical and thermal properties. Bioplastics cannot compete effectively with conventional low-cost plastics due to deficiencies in their formulation, processing, and end-of-life disposal.
- Why are phthalate plasticizers becoming bioplasticizers?
- Owing to health concerns, depletion of crude resources and other factors, there is a gradual drift from traditional phthalate plasticizers to bioplasticizers in the plastic industry. Bioplasticizers are derived mainly from biomass sources including agricultural products, it’s by-products and waste.
- Which plasticizers are used in the development of bioplastics?
- The plasticizers most used in the development of bioplastics are glycol, glycerol, sorbitol, fructose, sucrose, and mannose [29, 44]. Glycerol and sorbitol have been reported to improve mechanical properties; however, they decrease the biodegradation capacity of potato-based bioplastics .
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
