Why bother?
Yes, let’s save the planet:
• Reduce CO2
• Reduce embodied energy
• Reduce reliance on finite resources
• Move towards sustainable societies
• Increased recycling opportunities (even incineration)
![Page 9: Technology Overview: Biocomposites · Technology Overview: Biocomposites Composites Engineering Show, 4th Nov 2015, 15.00-16.00 A Biocomposites Industry for the Future Chris Hare](https://reader030.fdocuments.us/reader030/viewer/2022040810/5e517633e9637f5b832c5b44/html5/thumbnails/9.jpg)
Why bother?
Commercial advantages:
• Light-weighting
– E.g., replace glass fibres with natural
fibres
• Noise and vibration reduction
– E.g., inter-laminar layers
• An aesthetically beneficial product
– E.g., natural fibres can lend a unique
look and proclaim their greener origins

But we can’t do that without:
• A cost competitive product
• An equivalent performance product
• A processing method that is feasible
• A supply chain
