Which of the following statements is/are correct regarding the Bangalore process of composting solid waste?

1. Bangalore process is primarily anaerobic in nature.

2. Considerable heat gets evolved, and the temperature rises to about 75°C.

3. Continuous turning and handling of piled up mass is required for this process.

Explanation:

Bangalore Process of Composting

The Bangalore process of composting involves the anaerobic decomposition of organic solid waste. This process relies on the absence of oxygen to break down organic matter, which distinguishes it from aerobic composting methods.

• Anaerobic Nature: The process is primarily anaerobic, meaning it occurs without the presence of oxygen.

• Heat Generation: During the decomposition, considerable heat is evolved, and the temperature can rise significantly, often reaching up to about 75°C.

• No Continuous Turning Required: Unlike aerobic composting, the Bangalore process does not require continuous turning and handling of the piled-up mass.

Analyzing the Given Statements

1. Statement 1: "Bangalore process is primarily anaerobic in nature." (Correct)

   • This statement is accurate as the Bangalore process relies on anaerobic conditions for the decomposition of organic waste.

2. Statement 2: "Considerable heat gets evolved, and the temperature rises to about 75°C." (Correct)

   • Heat generation is a characteristic of the Bangalore process, and temperatures can indeed rise to around 75°C during the decomposition.

3. Statement 3: "Continuous turning and handling of piled up mass is required for this process." (Incorrect)

   • Continuous turning and handling are not required in the Bangalore process, as it is an anaerobic method that does not depend on regular aeration.
