The correct answer is Both I and II

Understanding Vermicomposting and Plastic Waste Composting

Let's analyze each statement to determine its correctness.

Analyzing Statement I: Vermicomposting Definition

Statement I says: Converting kitchen waste into compost through worms or red earthworms is called vermicomposting.

Vermicomposting is indeed a natural process where specific types of earthworms, most commonly red wigglers (Eisenia fetida), are used to break down organic matter, such as kitchen scraps, paper, and cardboard, into a nutrient-rich soil amendment called vermicompost.

The worms consume the organic waste and excrete castings, which are highly beneficial for soil health and plant growth. This process is an efficient way to manage organic waste and produce valuable compost.

Therefore, Statement I accurately defines vermicomposting.

Analyzing Statement II: Plastic Waste Composting

Statement II says: It is not possible to convert plastics into less harmful substances by composting.

Plastics are synthetic materials. Most types of plastics are not biodegradable in typical composting environments. They do not break down significantly into simpler, less harmful substances through the action of microbes or worms in a standard compost pile or vermicomposting setup.

While some specialized industrial processes or specific types of bioplastics might degrade under controlled conditions, common plastics like polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) persist in the environment for hundreds or even thousands of years. Placing them in a compost pile does not convert them into compost or less harmful substances; they essentially remain as plastic fragments.

Therefore, Statement II is correct. Plastics are not converted into less harmful substances by composting.

Conclusion

Based on the analysis:

  • Statement I is correct as it accurately defines vermicomposting.
  • Statement II is correct as plastics do not break down through standard composting methods.

Since both statements are correct, the option stating that both I and II are correct is the right answer.
