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

The question asks about the application of Polyblend, a fine powder made from recycled modified plastic. To determine the correct use of Polyblend, let's analyze each option:

1. Making plastic sacks: Plastic sacks are commonly manufactured using new or recycled plastic materials rather than by employing fine powders like Polyblend. This option is unlikely because it does not align with traditional practices of creating plastic materials.
2. Use as a fertilizer: Fertilizers are typically made from organic materials or synthesized chemicals that provide essential nutrients to plants. Polyblend, being a recycled plastic, does not contain the necessary nutrients to be used as a fertilizer. Therefore, this option can be ruled out.
3. Construction of roads: Polyblend is indeed recognized as a valuable material in road construction. When mixed with bitumen, Polyblend enhances the properties of the road surface, making it more durable and less susceptible to water damage. This usage of recycled plastics in road construction has been successfully implemented in various parts of India, leading to improved road infrastructure. Thus, this option is correct.
4. Making tubes and pipes: While plastic is commonly used in manufacturing tubes and pipes, these products are generally made using solid plastic materials, not in powdered form like Polyblend. Therefore, this is not a typical or practical application of Polyblend.

Upon examining all options, the most appropriate application of Polyblend is in the construction of roads. The use of Polyblend provides environmental benefits and enhances road quality, making it a sustainable and practical choice.
