Biobased Polymer Composites: A Review
Summary
This review surveyed the development of biobased polymer composites using natural fibers like hemp, flax, and sisal, highlighting their potential as sustainable alternatives to synthetic materials while discussing challenges in mechanical performance and processing.
Global environmental concerns, as well as the rapid depletion of non-renewable fossil fuel-based resources, have prompted research into the development of sustainable, environmentally friendly, and biodegradable materials for use in a variety of high-end applications. To mitigate the environmental setbacks caused by nonbiodegradable materials, the development of biocomposites with improved mechanical performance is gradually gaining momentum. Natural fibers such as hemp, flax, and sisal have been well incorporated into biocomposite development. Nonetheless, the impact of functional moieties in their life cycle cannot be underestimated. In this review paper, a detailed discussion of the characteristics and components of biocomposites is presented. The treatment of composite materials (alkali and acetylation), as well as several manufacturing processes (hand layup, 3D printing, extrusion, etc.) and the applications of biocomposites, which are not limited to the aerospace industry, packaging, biomedicine, etc., are presented. Biocomposites with excellent durability, performance, serviceability, and reliability must be produced to expand their applications.

Sustainable Biodegradable Biocomposites Reinforced With Natural Fibers: A Review on Processing, Properties, and Degradation
As concern grows about plastic waste and microplastic pollution from synthetic polymers, this review examines biodegradable biocomposites reinforced with natural plant fibers as a more sustainable alternative. The authors find that these materials can match or exceed the mechanical performance of conventional plastics while actually degrading in the environment — but note a critical gap: lab biodegradation tests often do not reflect real-world conditions, creating uncertainty about how quickly these materials actually break down. Better standardized testing and lifecycle analysis are needed to confirm whether natural fiber biocomposites can genuinely replace conventional plastics at industrial scale.
Future Prospects of Biodegradable Natural Fiber Composites: Innovations and Enhanced Performance in Roofing and Packaging Applications
Despite its title referencing sustainable composites and roofing/packaging, this paper studies the development of biodegradable natural fiber composites (from hemp, jute, and flax) as alternatives to synthetic fiber materials — not microplastic pollution research. It examines materials science for sustainable construction and packaging applications and is not directly relevant to microplastic contamination or human health.
