Which of the following is a common method used to recycle plastic waste?

  1. Mechanical Recycling

  2. Chemical Recycling

  3. Pyrolysis

  4. All of the above


Correct Option: D
Explanation:

Mechanical recycling involves melting and reshaping plastic waste into new products, chemical recycling breaks down plastic into its original components for reuse, and pyrolysis converts plastic into oil or gas.

What is the primary goal of recycling electronic waste (e-waste)?

  1. To recover valuable metals and materials

  2. To reduce the environmental impact of e-waste

  3. To create awareness about responsible e-waste disposal

  4. All of the above


Correct Option: D
Explanation:

Recycling e-waste aims to recover valuable materials, minimize environmental harm, and promote responsible disposal practices.

Which technology is commonly used to recycle paper waste?

  1. Pulping

  2. Deinking

  3. Bleaching

  4. All of the above


Correct Option: D
Explanation:

Paper recycling involves pulping to break down paper into fibers, deinking to remove ink and impurities, and bleaching to brighten the fibers.

What is the main objective of anaerobic digestion in waste management?
