At its core, a biocomposite is a combination of a matrix—often a polymer—and
reinforcement derived from biological sources such as plant fibers, agricultural residues,
or other renewable resources. Unlike traditional composites that employ synthetic fibers
like glass or carbon, biocomposites integrate materials like flax, hemp, jute, or kenaf. The
matrix can be either synthetic polymers or bio-based polymers such as polylactic acid
(PLA) and polyhydroxyalkanoates (PHA).
This integration creates a material that benefits from the mechanical strength of the

typically with lower stiffness.
Thermal degradation of natural fibers generally initiates around 200°C, limiting processing
temperatures. This necessitates careful selection of matrix materials and processing
techniques to maintain fiber integrity. In terms of environmental impact, lifecycle
assessments frequently demonstrate that biocomposites offer reductions in greenhouse
gas emissions and fossil fuel consumption by up to 40-60% compared to glass fiber
composites.
Applications Driving the Biocomposites Market
The application spectrum for biocomposites is broad and steadily expanding. Key sectors
