Ian Melville
Overview History/ Common Uses
Problem : Current Plastics Unsuitable
Solution : BioFibers
Economic Impact
Drawbacks
Future Projections
History / Common Uses Composite plastics started 1940s Urea, Melamine and Glass Fiber
Problems with Current Plastics Non-Biodegradable
10,000,000 Tons of plastic disposed of per year
Dominating packaging industry
BioFibers Characteristic of Fiber depends on
location on plant:Leaf Origin
○ Pinapple Leaf, HenequenSeed Origin
○ CottonBast Origin
○ Flax, HempFruit Origin
○ Coconut Husk
Bio Fibers Renewable BioFibers : 2E11 Tons/year
Synthetic Fibers : 1.5E8 tons/year
BioFibers Natural Fibers vs Synthetic Fibers
Economic Impact
Economic Impact
Drawbacks Lower resistance to heat
Variable market for biofiber components
Traditional plastics already have infrastructure built
