Question

Read the following statements and select the correct ones.
Ahmed khan, a plastic sack manufacturer of Bangalore, in 1998, developed polyblend, a fine powder of recycled modified plastic.
In collaboration with RV College of engineering and Bangalore City Corporation, The proved that the mixture of polyblend and bitumen was better for road carpeting as it had better water repellent property.
By 2002, more than \[40\,km\]roads of Bangalore were laid with the help of khan's mixture.
Rag pickers who used to get \[0.40\,per\,kg\]of plastic waste started getting Rs. 6.00 from Ahmed khan.
Innovation like polyblend might help modern society from being smothered with plastic waste.
A) (i), (ii), and (iii)
B) (ii), (iv), and (v)
C) (iii), (iv) and (v)
D) All of these

Answer 1

Hint:Plastic chemical is synthetic or semi-synthetic organic compounds which are malleable and molded into solid objects. Plasticity is the common term for all materials which can deform irreversibly without breaking.

 Complete answer:
>Plastics are organic polymers having high molecular mass and also contain some other substances. They are synthetic and commonly derived from petrochemicals.
>A plastic sack manufacturer in Bangalore has found the perfect answer for all the plastic problems and to reduce the increased accumulating plastic waste.
>Plastic sack manufacturer Ahmed Khan who is 57 years old. He was making these sacks for 20 years. >About 8 years ago, he realized that plastic waste was a very big problem.
>Polyblend, a powder of recycled modified plastic.
>Polyblend Mixture,blend with the bitumen that is used to lay roads.
>After RV College of engineering and the Bangalore city corporation, Ahmed Khan demonstrated that mixture of polyblend and bitumen when used to lay roads increase the bitumen's water repellent properties and help to enhance road life by factors of 3.
>Using Khan's technique by the year 2002, more than \[40\,km\]road in Bangalore has already been laid. At this rate Khan will soon see a shortage of plastic waste in Bangalore, to produce polyblends.

 So, the correct answer is all of these i.e, option ‘D’.

Note:Plastic has a very harmful effect on humans as well as on the environment. Plastic affects the food chain, groundwater pollution, air pollution, land pollution and kills animals.
