Bio-Composite
materials derived from natural, renewable sources have received significant interest in recent years, in particular due to the increased awareness of and drive towards more environmentally sustainable technologies. In many cases bio-based materials offer weight reduction, added functionality (e.g. damping / impact absorption) and occupational health benefits. A significant market driver for high volume applications is the potential to disassociate material costs from the fluctuating price of oil and energy.
Environmental:
In most cases, natural fibres have lower environmental impact than glass fibres due to reduced CO2 emissions and energy consumption during production. During the use phase, natural fibres can have a positive environmental impact due to their low weight. At the end of life, natural fibre composites can be recycled, biodegraded (when used with biodegradable polymers), or can be incinerated for energy recovery.
Applications: A wide range of applications exist for natural composites, most notably in the automotive, construction, consumer and leisure markets. Commercial applications of natural fibre-synthetic polymer composites include WPC decking and outdoor furniture and automotive parts such as door liners and trim panels. The demand from designers, manufacturers and consumers for environmentally friendly products will inevitably drive the rapid development of other biocomposite materials and products.
