Question

Polyblend, a fine powder of recycled modified plastic, has proved to be a good material for:

• A. making plastic sacks
• B. use as a fertilizer
• C. construction of roads
• D. making tubes and pipes

Answer 1

The Correct Option is C

This question pertains to the usage of Polyblend, a material made from recycled modified plastics. The question asks us to determine the application for which Polyblend has been found effective. Let us use logical reasoning and the provided options to arrive at the correct solution:

1. Understanding Polyblend: 
Polyblend is known for being a fine powder derived from recycled modified plastic. Its development is an example of innovative recycling strategies aimed at reducing plastic waste and finding sustainable solutions for its disposal.

2. Analyzing the Options:

1. Making plastic sacks: Although Polyblend is plastic-based, it is not specifically notable or widely used for manufacturing plastic sacks. The production of plastic sacks typically utilizes polyethylene or polypropylene, not recycled modified plastics in powdered form.
2. Use as a fertilizer: Fertilizers usually consist of organic matter or specific chemical compounds beneficial for plant growth. Polyblend being a plastic product doesn’t contribute to soil fertility and hence is unsuitable for this use.
3. Construction of roads: This is the correct application of Polyblend. It has been successfully used in road construction because it enhances the durability and life of the roads. The addition of Polyblend in asphalt improves the binding, makes the roads water-resistant, and helps in absorbing heat, which contributes to the longevity of the roads. This is a widely recognized application in places like India where plastic waste is a significant environmental challenge.
4. Making tubes and pipes: Similar to plastic sacks, the production of tubes and pipes involves different types of plastics designed to withstand various pressures and conditions. Polyblend is not notably utilized for this purpose.

 

3. Conclusion:
Based on the analysis, Polyblend is most effectively used in the construction of roads. This application not only aids in recycling plastic waste but also provides a practical solution to enhance road quality. Thus, the correct answer is construction of roads.
