Could someone please help me with some good advantages and disadvantages of using biopolymer over other polymers. i know ones like biodegradable and that but a birt more if possible
thankyou

from memory, bio is obviously good coz it's biodegradable. would be even better if they can use solar energy to make it, so it wouldnt contribute to greenhouse effect.

disadvantage is that current methods are inefficient and not economical for mass production

Hi schooly

It is difficult to present a detailed discussion of the advantages and disadvantages of biopolymers without refrence to specific examples. Otherwise you'll end up just stating the obvious biodegradability, renewable resource etc.

Some starting information including a list of suitable biopolymers is available here, Thickett's Pathways and the other textbooks like the Longman Chem Contexts include some of these.

You can then go on to say things like "Orica's Biopol is curently too expensive to be a viable replacement for petroleum based plastics..."

Be sure when making your notes to address all the possible questions implied in the syllabus .

they can be made from a renewable resource

They are biodegrabable and all those obvious ones.

Disadvantage: pretty expensive to make compared with the rest of the market. Expecially if they are created from biomass like cellulose or starch.
