Torn clothes can be recycled to form bags and into other usable forms. Metallic and plastic discards can be melted and recycled into usable forms any number of times. Recycling reduces environmental pollution and uses less energy as compared to the production of new materials from raw materials.
Hence, all the options are correct.
So, the correct answer is 'All the above'.

During recycling of paper, paper is broken down into

  1. Cellulose

  2. Plastic

  3. Screens

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The process of waste paper recycling involves mixing of used paper with water and chemicals to break it down. It is then chopped  and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called as pulp or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Then it can be made into new recycled paper or other products.

So, the correct answer is 'Cellulose'
