Question 1

What is the primary objective of the 'Extended Producer Responsibility' (EPR) policy?

Accepted Answer

To make manufacturers responsible for the product's end-of-life. EPR shifts the responsibility of waste management back to the manufacturer. This encourages producers to design products that are easier to recycle or reuse. It is a key strategy used globally to manage electronic and plastic waste.

Question 2

Which type of waste is specifically categorized under 'Yellow Bag' in clinical waste management?

Accepted Answer

Human anatomical waste. Yellow bags are used for highly infectious waste such as body parts and soiled dressings. This waste is usually disposed of through incineration to ensure pathogens are destroyed. Proper segregation at the source is vital for hospital safety.

Question 3

Which chemical element is the primary concern during the disposal of old fluorescent lamps?

Accepted Answer

Mercury. Fluorescent lamps contain small amounts of mercury vapor which is toxic to the nervous system. If broken in landfills, mercury can leach into the groundwater or evaporate into the air. Special recycling centers are required to safely recover this liquid metal.

Question 4

The process of 'Vermicomposting' involves the use of which organism to decompose organic waste?

Accepted Answer

Earthworms. Earthworms break down organic matter into nutrient-rich manure called vermicast. This method is faster than traditional composting and produces high-quality organic fertilizer. It is highly effective for managing household kitchen waste.

Question 5

What does the 'Blue Bin' signify in a two-bin waste collection system?

Accepted Answer

Dry recyclable waste. The blue bin is intended for dry waste like paper, plastic, and metal. Segregating dry waste helps in efficient mechanical recycling and reduces landfill pressure. Biodegradable waste is typically kept in green bins.
