After watching a programme on TV , about the problem of disposal of carry home bags and packaging material , Ankit - a clas XII student , suggested that instead of synthetic polymers carry home bags and packaging material used should be made up paper/ cardboard.
After reading the above passage , answer the folllowing questions :
(i) Name the polymer used to make carry home bags and packaging material.
(ii) What values are expressed by Ankit ?
(iii) Give the name , structure and one used of a biodegradable aliphatic polyester.

Explanation

(i) Carry home bags and packaging material is made up of low density polythene.
(ii) Carry home bags are usually made up of low density polythene which is a non-biodegradable polymer and thus creats disposal problem. On the other hand, paper/cardboard is a natural biodegradable polymer which disintegrate by itself over oa period of time either by hydrolysis or by bacterial degradation or oxidation in the environment thereby saving the environment from getting polluted. Further , used paper or cardboard can be easily recycled.
(iii) The name of a biodegradable aliphatic polymers is : poly `beta`- hydroxybutyrate -co-`beta`-hydroxyvalerate (PHBV). It is used in speciality packaging , orthopaedic devices and in controlled drug release.
