Question

Determine the correctness or otherwise of the following Assertion [a] and the Reason [r].

Assertion [a]: One of the best ways to reduce the amount of solid wastes is to reduce the consumption of raw materials.

Reason [r]: Solid wastes are seldom generated when raw materials are converted to goods for consumpton

1. Both [a] and [r] are false
2. Both [a] and [r] are true and [r] is the correct reason for [a]
3. Both [a] and [r] are true but [r] is not the correct reason for [a]
4. [a] is true but [r] is false

Answer 1

Correct Answer - Option 4 : [a] is true but [r] is false

Explanation

a) Reducing solid waste is reducing the amount of garbage that goes into our landfills. These are items we use each day, and then get rid of by putting them into the trash. Solid waste comes from homes, businesses, and industries.

We can reduce the amount of solid waste by reducing the consumption of raw materials: 

Ex:

1) Use a reusable bottle/cup for beverages on-the-go

2) Use reusable grocery bags, and not just for groceries

3) Buy secondhand items and donate used goods

4) Curb your use of paper: mail, receipts, magazines

b) 

• Both technological processes and consumptive processes result in the formation of solid wastes.
• Solid waste is generated, in the beginning, with the recovery of raw materials and thereafter at every step in the technological process as the raw material is converted to a product for consumption generation of solid waste during technological processes. Ex: mining, manufacturing, and packaging.

c) The objective of solid waste management is to reduce the quantity of solid waste disposed off on land by the recovery of materials and energy from solid waste. This in turn results in the lesser requirement of raw material and energy as inputs for technological processes.
