Question 1

What are bioplastics and their advantages

Answer 1

Not sourced from crude oil but from renewable biomass. This leads to:
1) less usage pf finite resources.
2) More energy as less energy intensive process
3) Biodegradable

Question 2

Polyhydroxybutyrate
(PHB) Biopol ™
Non
toxic, insoluble in water, high melting point

Answer 2

> > > Made by plant sugar and glucose form sweet potatoe and peas etc..
Can be injection moulded and vacuum
formed.
shampoo bottles, disposable razors, disposable cups, surgical stitches, surgical pins, disposable knives and forks, woven medical patches and nappy linings

Question 3

Polycaprolactone (PCL)
e.g. Polymorph

Answer 3

melting point of 68 and soften when submerged in hot water.

Question 4

Polylactide/ Polylactic Acid (PLA)
*
A biodegradable plastic made from corn starch

Answer 4

The resulting resin can be injection and blow moulded, to form
